See why we picked itKey takeaways
- For SaaS, product-event triggers matter more than templates. Pick a tool your app can send events to, such as signups, invites and usage limits.
- Loops and Brevo are the only picks here with free plans: Loops up to 1,000 contacts, Brevo at 300 emails a day.
- B2B products sold to teams need account-level data. Userlist, Encharge and Ortto model companies as well as users.
- Send transactional and lifecycle email from one platform when you can. Customer.io, Loops, Userlist, Encharge and Brevo all do both.
- Iterable and Braze are for scaling, high-volume products with data teams. Most SaaS startups do not need them yet.
What is email marketing software for SaaS?
Email marketing software for SaaS is a platform that sends onboarding, lifecycle, marketing and transactional emails based on what users do inside your product, not just on a calendar. The best email marketing software for SaaS connects to your app through an events API or a data tool like Segment, so a signup, a missed setup step or a trial nearing its end can trigger the right email automatically.
It needs to do more than a newsletter tool. A SaaS company has to activate trial users, convert them to paid, announce features, recover failed payments and reduce churn, often while sending password resets and receipts too. B2B products also need to see the account, not just the person, and growing teams eventually want push, SMS or in-app messages alongside the inbox.

The 9 best email marketing software for SaaS in 2026
SaaS email works best when it reacts to product behavior. These 9 tools are ranked for SaaS teams, from simple startup tools to enterprise engagement platforms.
#1Best overall for event-driven SaaS lifecycle messaging
Customer.io
A data-driven messaging platform that sends email, push, SMS and in-app messages triggered by what users do in your product.
- Paid plans from
- $100/mo
- Free plan
- No (free trial)
- Best for
- SaaS and app teams with developer or data resources
- Works on
- Web; SDKs for web, iOS, Android, React Native and Flutter
Customer.io is our top pick for SaaS email marketing because it is built around product events. You send it what users do, such as signing up, inviting a teammate or hitting a usage limit, and Journeys use those events to time onboarding, activation and retention emails. Segments update in real time, so a user who finishes setup drops out of the nudge sequence straight away.
It also covers the channels a growing SaaS product ends up needing. The same workflow can send email, push, SMS and in-app messages, and receipts or password resets go through the transactional API with shared templates and reporting. Data Pipelines, Segment, Snowflake and BigQuery connections suit teams with a real data stack, though that also means you need engineering time to set it up.
Key features
- JourneysA visual builder for triggered lifecycle campaigns that branch on user attributes and events, so trial onboarding, activation nudges and churn-risk emails run automatically.
- Behavioral segmentationSegments built from tracked product events and attributes update in real time, so a user who completes a step stops getting reminders about it.
- Email, push, SMS and in-app in one workflowSend each step on the channel that fits, for example an in-app tip first and an email only if the user does not act.
- Transactional messagesSend receipts, password resets and account emails through the API with the same templates and reporting as marketing email.
- A/B and holdout testingTest variants and keep holdout groups inside journeys to see whether an onboarding sequence actually changes activation.
Pricing
| Plan | Price | What you get |
|---|---|---|
| Essentials | $100/mo | Starts at 5,000 profiles and rises with profile count; journeys, segments, newsletters, email, push, SMS and in-app messaging |
| Premium | Custom (annual) | Higher limits, advanced features, premium support and onboarding |
| Enterprise | Custom (annual) | Custom volume, security and compliance options, dedicated support |
List prices as of November 2026; plans change often, so check the vendor's pricing page before you buy. Free trial available.
Pros and cons
Pros
- Very flexible event-based targeting
- Email, push, SMS and in-app in one workflow builder
- Strong APIs and data pipelines for technical teams
- Handles transactional and marketing email together
Cons
- No free plan
- Entry price is high for small user bases
- Needs developer help to send events and set up data
Is it right for you?
Choose Customer.io ifYou track product events and want onboarding, activation and retention messages to react to what each user actually does.
Look elsewhere ifYou are pre-launch with a small list and no developer time, where Loops is cheaper and simpler.
#2Best for early-stage SaaS startups
Loops
An email platform for SaaS companies that handles product updates, automated lifecycle emails and transactional email in one place.
- Paid plans from
- $49/mo
- Free plan
- Yes (1,000 contacts)
- Best for
- SaaS startups and software companies
- Works on
- Web, API
Loops is an email platform built specifically for SaaS startups. It covers the three kinds of email a young product sends: campaigns for product updates and newsletters, loops (automations) for onboarding and trial sequences, and transactional email for password resets and receipts. Having all three in one tool means one sender reputation, one set of templates and one place to look when a user says they never got an email.
Its appeal is speed and simplicity. The Events API lets your app tell Loops what users do, contact properties store details like plan or signup date, and integrations with Stripe, Segment, Supabase and Clerk fit a typical startup stack. The free plan covers up to 1,000 contacts, and paid plans start at $49/mo with unlimited sends and Loops branding removed.
Key features
- Loops (automations)Event- and property-triggered sequences for onboarding, trial conversion and re-engagement, built without a complex canvas.
- Transactional emailSend password resets, receipts and other app emails via API from the same platform as your marketing email.
- Events APISend product events from your app so emails react to what users do, such as finishing setup or skipping it.
- CampaignsOne-off product updates, changelogs and newsletters to your whole audience or a segment.
- Stack integrationsConnects with Stripe, Segment, Zapier, Supabase and Clerk, which covers billing, auth and data tools common in early SaaS.
Pricing
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | Up to 1,000 contacts; campaigns, loops and transactional email with a monthly send cap |
| Paid | $49/mo | From 5,000 contacts, rising with contacts; unlimited sends and Loops branding removed |
| Larger lists | Higher | Same features at higher contact counts |
List prices as of November 2026; plans change often, so check the vendor's pricing page before you buy.
Pros and cons
Pros
- Built specifically for SaaS lifecycle email
- Marketing and transactional email in one tool
- Free plan for early-stage products
- Simple, modern interface
Cons
- Email only; no SMS or in-app messaging
- Lighter reporting than larger marketing platforms
- Limited account-level (company) data for B2B
Is it right for you?
Choose Loops ifYou are an early-stage SaaS team that wants product, lifecycle and transactional email in one simple, affordable tool.
Look elsewhere ifYou need push, SMS or in-app messages, or account-level targeting for a B2B sales motion.
#3Best for B2B SaaS with account-level messaging
Userlist
Behavior-based email automation for SaaS companies, with support for both individual users and the companies they belong to.
- Paid plans from
- Priced by tracked users
- Free plan
- No
- Best for
- B2B SaaS companies
- Works on
- Web, API
Userlist is built for B2B SaaS, where the customer is usually a company with several users rather than one person. It stores users and the accounts they belong to, so you can trigger an email when an account is close to renewal, when a team has only one active seat, or when the admin has not finished setup. Most general email tools only see individual contacts, which makes this kind of messaging awkward.
Beyond account data, it covers the usual SaaS email jobs in one small, focused product. Behavior-based campaigns react to what users do or do not do, broadcasts handle product announcements, and transactional email sends invitations and notifications. The visual campaign builder supports branches and conditions, and Segment, Zapier and Stripe integrations bring in product and billing data.
Key features
- Company-level messagingModels users and their companies, so you can target accounts, not just people, which suits team-based B2B products.
- Behavior-based campaignsSequences triggered by what users do, or fail to do, in your product, such as never creating a first project.
- Visual campaign builderLay out multi-step campaigns with branches and conditions on a canvas.
- Transactional emailSend invitations and notifications through the same platform as lifecycle email.
- SegmentationBuild segments from user and company properties and events, for example accounts on a trial with fewer than three active users.
Pricing
| Plan | Price | What you get |
|---|---|---|
| Paid plans | Priced by tracked users | Behavioral campaigns, broadcasts and transactional email |
List prices as of November 2026; plans change often, so check the vendor's pricing page before you buy.
Pros and cons
Pros
- Designed for B2B SaaS with user and company data
- Behavior triggers from product events
- Lifecycle, broadcast and transactional email in one place
- Small, focused product that is easy to learn
Cons
- No free plan
- Email only; no SMS or in-app messages
- Smaller integration library than larger tools
Is it right for you?
Choose Userlist ifYou sell a team-based B2B product and need emails that react to account health, not just individual users.
Look elsewhere ifYou run a B2C app or need SMS, push and in-app messages alongside email.
#4Best for trial and onboarding flows tied to Stripe and your CRM
Encharge
A marketing automation platform for B2B SaaS that uses product, CRM and billing data to run behavior-based email flows.
- Paid plans from
- Priced by contacts
- Free plan
- No
- Best for
- B2B SaaS companies and marketing teams
- Works on
- Web, API
Encharge is marketing automation built for B2B SaaS lifecycle email. Its visual flow builder handles the jobs that matter most in a trial-led business: onboarding new signups, nudging trial users toward activation, converting trials to paid and nurturing leads that are not ready yet. Flows can trigger on product events sent through Segment, the API or integrations.
Where it stands out is the data it can act on. Native integrations with Stripe, HubSpot, Salesforce and Intercom mean a flow can react to billing data from Stripe or contact and deal data from your CRM. Two-way CRM sync and lead scoring help hybrid product-led and sales-led teams pass the most engaged accounts to reps, and account-based features group people into companies.
Key features
- Visual flow builderBuild trial conversion, onboarding and nurture automations with triggers, conditions and actions on a canvas.
- Behavior-based emailsTrigger emails from product events sent via Segment, the API or integrations, without heavy custom engineering.
- CRM syncTwo-way syncs with HubSpot and Salesforce keep contact and deal data aligned between marketing and sales.
- Lead scoringScore leads on behavior and attributes so sales follows up on the trial accounts most likely to buy.
- Account-based marketingGroup people into companies and run flows on account-level data for longer B2B sales cycles.
Pricing
| Plan | Price | What you get |
|---|---|---|
| Growth | Priced by contacts | Flow builder, broadcasts, segmentation and core integrations |
| Premium | Priced by contacts | Adds account-based features, CRM integrations and more advanced tools |
| Enterprise | Custom (annual) | Higher volumes and support |
List prices as of November 2026; plans change often, so check the vendor's pricing page before you buy. Annual billing discount available.
Pros and cons
Pros
- Built for B2B SaaS lifecycle marketing
- Native integrations with Stripe, HubSpot and Salesforce
- Account-based features for B2B

Is it right for you?
Choose Encharge ifYou run a B2B SaaS trial and want flows driven by product usage, Stripe billing and CRM deal data.
Look elsewhere ifYou have a very small list and need a free plan, or you want multichannel messaging.
#5Best budget automation and CRM for SMB SaaS
ActiveCampaign

- Paid plans from
- $15/mo annual
- Free plan
- No (14-day trial)
- Best for
- Small and mid-sized businesses, SaaS and B2B marketers
- Works on
- Web, iOS, Android, API
ActiveCampaign is a general email marketing and automation platform, but it fits small SaaS companies that sell with a mix of marketing and sales. Its branching automation builder can combine email engagement, site visits and tags, which works well for nurturing leads from a demo request or webinar signup through a sales cycle that takes weeks.
Lead scoring and the built-in CRM let you pass hot leads to a pipeline without buying a separate sales tool, and site tracking shows which pages known contacts visit, such as your pricing page. A large library of automation recipes speeds up setup, and a Stripe integration is available. It is less suited to in-app behavior triggers than Customer.io or Loops.
Key features
- Advanced automation builderCombine email engagement, site visits and tags in branching automations, useful when a SaaS purchase decision takes weeks.
- Lead scoring and CRMScore contacts by behavior and move hot leads into a sales pipeline, which suits demo-led and sales-assisted SaaS.
- Site trackingTrack which pages known contacts visit, such as pricing or docs, and use those visits to trigger automations.
- Automation recipesStart from a large library of pre-built automation templates and adapt them to your funnel.
- Split testingTest subject lines and content in campaigns, and split paths inside automations.
Pricing
| Plan | Price | What you get |
|---|---|---|
| Starter | $15/mo annual | 1,000 contacts, rising with list size; email and automations |
| Plus | Higher | Starter features plus more automation, landing pages and reporting |
| Pro | Higher | Predictive sending and more reporting |
| Enterprise | Custom | Premium CRM integrations and dedicated support |

- Not built around product events like SaaS-specific tools
- Price rises quickly with contact count
Is it right for you?
Choose ActiveCampaign ifYou are a small SaaS team nurturing leads over long sales cycles and want automation plus a CRM on a budget.

- Paid plans from

- Works on
- Web (cloud)
Ortto, formerly Autopilot, suits SaaS growth teams that want their customer data and their messaging in the same place. Its customer data platform pulls contacts, events and accounts from your apps and CRM into one profile, so segments and journeys all work from the same data.
On top of that sit a clean visual journey builder, email and SMS, website capture widgets and built-in analytics with journey and revenue reports. Integrations with Salesforce, HubSpot, Segment, Stripe and Intercom cover most SaaS stacks, and account-based features group contacts into companies for B2B targeting. It is a lot of tool if you only send a monthly newsletter.
Key features
- Customer data platformBrings contacts, events and accounts from your apps and CRM into one profile that powers segments and journeys.
- JourneysA visual builder for multi-step campaigns that react to behavior, with branches, delays and goals such as trial conversion.

Choose Ortto ifYour growth team wants unified customer data, journeys and revenue reporting in one platform instead of stitching tools together.
Look elsewhere ifYou only need product updates and a few onboarding emails, where Loops is far simpler.
#7Best affordable mix of marketing and transactional email
Brevo
A marketing platform for email, SMS, WhatsApp and transactional messages, with plans priced by monthly email volume.
- Paid plans from
- $9/mo
- Free plan
- Yes (300 emails/day)
- Best for
- Small and mid-sized businesses and developers
- Works on
- Web; API and SMTP relay
Brevo, formerly Sendinblue, is the budget pick for SaaS companies that want marketing and transactional email from one vendor. Every plan, including Free, can send app emails such as receipts and password resets through the API or SMTP relay, with webhooks and log retention. That makes it easy for a small team to cover product email and newsletters without two contracts.
For lifecycle email, the Standard plan at $18/mo adds marketing automation, A/B testing, send time optimization and web and event tracking, so you can trigger workflows from product events. It is a general SMB platform rather than a SaaS-specific one, so account-level data is not its focus, and the jump to Professional at $499/mo for push, popups and contact scoring is steep.
Key features
- Transactional email on every planSend receipts, password resets and notifications through the API or SMTP relay, with webhooks and logs, even on Free.
- Marketing automationUnlimited multi-step workflows triggered by behavior and events on Standard and higher, for onboarding and re-engagement.
- Web and event trackingOn Standard, track events so automations and segments can react to product activity.
- Advanced segmentationFilter contacts by website activity, engagement and custom events, with unlimited saved segments.
- A/B testing and send time optimizationTest subject lines and content and send at the best time for each contact on Standard and higher.
Pricing
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | 300 emails/day, email campaigns, transactional email, forms, Brevo branding |
| Starter | $9/mo ($97/yr annual) | From 5,000 emails/mo (500 contacts), editor, templates, AI content generator, segmentation |
| Standard | $18/mo ($194/yr annual) | Adds marketing automation, A/B testing, send time optimization, web and event tracking, no Brevo logo |
| Professional | $499/mo | From 150,000 emails/mo, 10 seats, web and mobile push, popups, contact scoring |
| Enterprise | Custom | Dedicated IP, SSO/SAML, custom objects, tailored onboarding |

Pros and cons
Pros

- Pricing driven by email volume
- Full API and 150+ integrations
Cons
- Marketing automation requires Standard or higher
- Starter shows the Brevo logo unless you pay $12/mo extra
- Big price jump to Professional
Is it right for you?
Choose Brevo ifYou want transactional and marketing email from one cheap account and only need simple event-triggered workflows.
Look elsewhere ifYou need account-level B2B targeting or deep product-event journeys.
#8Best for larger product-led companies going cross-channel
Iterable
An enterprise customer engagement platform for orchestrating email, SMS, push and in-app messages from one data model.
- Paid plans from
- Custom
- Free plan
- No
- Best for
- Mid-market and enterprise consumer apps and larger SaaS companies
- Works on
- Web, API, iOS and Android SDKs
Iterable is for SaaS and app companies that have outgrown email-only tools and run large, product-led audiences. Its Studio journey builder lays out multi-step journeys triggered by real-time events and data, and every step can use email, SMS, mobile push, in-app or web push from one platform.
It fits teams with a modern data stack. Integrations with Segment, Snowflake, mParticle and Amplitude feed user events and profiles in, Catalog pulls content data into messages for personalization, and Experiments run A/B and multivariate tests across messages and journeys. The trade-off is cost and effort: pricing is quoted on annual contracts and setup needs data engineering.
Key features
- Studio journey builderA drag-and-drop canvas for multi-step, multichannel journeys triggered by events and data.
- Cross-channel messagingEmail, SMS, mobile push, in-app and web push from one platform, so lifecycle programs are not limited to the inbox.
- Real-time dataIngest user events and profiles via API and data integrations to trigger messages the moment users act.
- ExperimentsA/B and multivariate testing across messages and whole journeys.
- CatalogStore content or product data and pull it into messages for personalized recommendations, such as feature or template suggestions.
Pricing
| Plan | Price | What you get |
|---|---|---|
| Iterable | Custom (annual contract) | Platform pricing quoted on volume and channels |
Pricing is quoted by sales on annual contracts, based on volume and channels. Check the vendor's pricing page for current terms.
Pros and cons
Pros
- Strong multichannel orchestration
- Flexible data model for complex personalization
- Scales to very large audiences
- Rich integrations with modern data stacks
Cons
- No public pricing; enterprise budgets
- Requires technical setup and data engineering
- Overkill for small SaaS teams
Is it right for you?
Choose Iterable ifYou are a scaling product-led company with a data team and need email plus push, SMS and in-app at volume.
Look elsewhere ifYou are a startup or small B2B SaaS team, where Customer.io or Loops cost far less.
#9Best for enterprise, mobile-first consumer apps
Braze
An enterprise customer engagement platform for real-time, cross-channel messaging across email, push, SMS, in-app and more.
- Paid plans from
- Custom
- Free plan
- No
- Best for
- Large consumer brands, mobile apps and enterprises
- Works on
- Web, API, mobile SDKs (iOS, Android, React Native, Flutter and others)
Braze is an enterprise customer engagement platform, and it only makes sense for SaaS when your product looks like a high-volume consumer app. Canvas orchestrates journeys across email, mobile and web push, SMS and in-app messages with real-time triggers, and Content Cards add persistent messages inside your product, which is useful for feature announcements that should not depend on the inbox.
It is built for data-heavy teams. Cloud Data Ingestion syncs user data from warehouses such as Snowflake, Currents streams engagement data back out, and Liquid personalization pulls in user attributes and events. Braze is a publicly listed, established vendor, but pricing is sales-quoted on annual contracts and implementation needs engineers.
Key features
- CanvasVisual journey orchestration across channels with branching, delays and real-time triggers.
- Content CardsPersistent in-app and web feed messages that sit inside your product, alongside email.
- Cross-channel messagingEmail, mobile and web push, SMS and in-app messages from one platform.
- Cloud Data IngestionSync user data directly from data warehouses such as Snowflake, so segments match your source of truth.
- CurrentsStream engagement data in real time to your warehouse or analytics tools for reporting.
Pricing

|---|---|---|
| Braze | Custom (annual contract) | Packages quoted by sales based on users and volume |
Pricing is quoted by sales on annual contracts, based on users and volume. Check the vendor's pricing page for current terms.

- Real-time event processing at large scale
- Deep personalization and data integrations
- Publicly listed, established vendor
Cons
- No public pricing; expensive for small teams

How we chose the best email marketing software for SaaS
We started with the email and marketing automation tools in the MakeSuccessOnline directory and added well-known SaaS email tools we have not reviewed yet, such as Loops and Braze.

How to choose email marketing software for SaaS
- Map your lifecycle firstList the emails you need: welcome, onboarding steps, trial ending, upgrade, failed payment, feature news and win-back. That list tells you which features matter.
- Decide where your events come fromIf you already use Segment, pick a tool that connects to it. If not, check how easy the tool's events API is for your developers.
- Check B2B account supportIf you sell to teams, make sure the tool can group users into companies and trigger on account data.
- Keep transactional email togetherChoose a tool that also sends receipts and password resets, or confirm it works cleanly beside your current sender.
- Model the cost at 10x usersPrice the tool at your current user count and at ten times that, since most SaaS email tools price by contacts or profiles.
- Start simple, then expand channelsBegin with email. Move to Customer.io, Iterable or Braze only when you actually need push, SMS or in-app at scale.

Email marketing software for SaaS FAQ
What is the best email marketing software for SaaS?
Customer.io is the best email marketing software for SaaS for most product-led teams, because its journeys react to product events across email, push, SMS and in-app. Loops is the best pick for early-stage startups, and Userlist is best for B2B SaaS that needs account-level messaging.
What is the best free email marketing software for SaaS?
Loops is the best free option for SaaS, covering campaigns, automations and transactional email for up to 1,000 contacts with a monthly send cap. Brevo's free plan allows 300 emails a day and includes transactional email, but marketing automation needs its paid Standard plan.
How much does email marketing software for SaaS cost?
Budget tools cost $9 to $49 a month: Brevo Starter is $9/mo, ActiveCampaign starts at $15/mo billed annually and Loops paid plans start at $49/mo. SaaS lifecycle platforms like Customer.io start at $100/mo, and Iterable and Braze use custom annual contracts.
Loops vs Customer.io: which is better for SaaS?
Loops is better for early-stage SaaS teams that want simple product, lifecycle and transactional email with a free plan. Customer.io is better once you need complex event-driven journeys, real-time segments and channels beyond email such as push, SMS and in-app, and you have developer time to set it up.
Customer.io vs Braze: which should a SaaS company choose?
Most SaaS companies should choose Customer.io. It starts at $100/mo with a free trial and covers email, push, SMS and in-app. Braze is an enterprise platform with sales-quoted annual contracts, best for high-volume, mobile-first consumer apps with engineering and data teams.
What email marketing software is best for B2B SaaS?
Userlist is best for B2B SaaS because it models both users and the companies they belong to. Encharge adds Stripe, HubSpot and Salesforce sync plus lead scoring for sales-assisted trials, and ActiveCampaign is a budget option with lead scoring and a built-in CRM.
Should SaaS companies send transactional and marketing email from one tool?
Usually yes, if the tool supports both well. One platform means shared templates, one place to check delivery logs and a simpler setup. Customer.io, Loops, Userlist, Encharge and Brevo all send transactional email alongside lifecycle and marketing email. If you keep a separate sender, make sure both share the same domain authentication.
How do I choose email marketing software for SaaS?
Start by listing your lifecycle emails, then check how each tool receives product events, whether it supports account-level data for B2B, and whether it sends transactional email. Finally, price it at your current user count and at ten times that, since most tools charge by contacts or profiles.
