Which cold email agency for cybersecurity is best?
The best cold email agencies for cybersecurity in 2026 include Leadium for multichannel security outbound, Callbox for vendors selling worldwide, LevelUp Leads for fractional SDR support, Purple Sales for outbound plus HubSpot and A-Sales for European buyers. UltraGrowthMedia is the pick for teams that want cold email and LinkedIn outreach from one team. Only 7 of the 14 agencies we track list cybersecurity clients, and the median minimum is $1,750 a month.
Key takeaways
- Only 7 of the 14 agencies in our directory list cybersecurity clients for cold email, so this page also includes adjacent B2B technology specialists. Each pick says whether it lists security work.
- The median minimum for a cold email agency for cybersecurity is $1,750 a month, with 50% of agencies in the budget tier and 17% above $5,000, so outbound support is within reach of seed-stage vendors.
- A cold email agency for cybersecurity must protect your domain: ask about warm-up, separate sending domains and how bounces and spam complaints are handled before any list goes out.
- CISOs and security leads get heavy volumes of vendor email, so favour agencies that research accounts and write short, technical messages over high-volume templates.
- Only 14% of agencies here offer AI search work, so plan separately for how your product shows up when buyers ask AI tools. North American agencies in the pool show a $5,000 median minimum.

The 10 best cold email agencies for cybersecurity in 2026
Each agency below leads a specific category. Start with the one that matches your situation rather than reading top to bottom.
#1Best overall for security outbound with proof
Leadium
Outbound appointment setting for B2B teams via email, calls and LinkedIn
Leadium in Las Vegas lists cybersecurity first among its industries, ahead of SaaS and freight, and holds a 5.0 on Clutch across 90 reviews.

Notable clients
- Segment
- OpenEdge

Watch out
Reviewers mention a slow initial ramp-up, and it names no security-specific case study.
#2Best for cold email plus LinkedIn outreach
UltraGrowthMedia
Full-stack marketing for ambitious growth-stage brands.
UltraGrowthMedia runs cold email as a complete outbound programme: ICP definition, about two weeks of domain and DNS set-up on secondary sending domains, verified lead lists, copywriter-written sequences and ongoing A/B testing. It says it typically targets 10 to 20 qualified meetings a month from email and 15 or more from LinkedIn, and one client reports a 60% drop in cost per lead within 90 days. SEO and AI search sit in the same team for when outbound alone isn't enough. Founded in 2022 by Tushar Dey, the 27-person remote team works in weekly sprints, clients talk directly to the practitioners doing the work, and progress shows up on live reporting dashboards. Retainers start at $3,500 a month.
Watch out
It is a newer team, founded in 2022, with few named case studies or third-party reviews, so ask for references and a walkthrough of a live client dashboard before signing.
Run by our team.

LevelUp Leads in Laguna Beach lists cybersecurity among its industries, and a cybersecurity client, PlugSecure, reviewed it positively on Clutch.

It has 61 Clutch reviews at 5.0, a $5,000 minimum, and one reviewer cites $4,000 to $7,000 a month. Its named case studies are mostly finance.

Notable clients
- Sully.ai
- Clarity

B2B appointment setting and outsourced SDRs working phone, email and LinkedIn
Launch Leads in Salt Lake City has operated since 2009 and lists IT and security, software and cloud, and banking and payments among its industries.

Belkins in Denver does not list cybersecurity as a focus, but it works with B2B technology buyers and lists SaaS and IT services among its industries.

Notable clients

Gripped in London lists cybersecurity among its verticals with fintech, HR tech and dev tools, and is a B2B SaaS growth agency founded in 2017.

How to choose a cold email agency for cybersecurity
- Define the target accountsList the roles, company sizes and tech environments you sell to. Security outbound fails when lists are too broad.
- Ask how list data is sourcedFind out where contacts come from and how opt-outs are honoured, especially for UK and EU recipients under GDPR and PECR.
- Check deliverability practiceAsk about dedicated sending domains, warm-up, authentication and keeping spam complaints low, in line with Gmail sender rules.
- Review sample messagesRead example emails written for technical buyers. Reject generic fear-based copy.
- Align with your sales teamAgree who answers replies, how quickly, and what counts as a qualified meeting.
- Start with a short pilotRun one segment for 60 to 90 days, then expand based on replies and meetings, not volume sent.
Questions to ask
- Have you run cold email for cybersecurity or infrastructure vendors, and what happened to reply rates?
- Where do your contact lists come from, and how do you handle opt-outs and GDPR?
- How do you protect our primary domain and monitor deliverability?
- Who writes the emails, and who understands our product enough to be credible?
- How are meetings qualified before they reach our sales team?
- What do we own at the end, including domains, lists and sequences?
Red flags
- Promised meeting counts with no definition of a qualified meeting.
- Sending from your primary domain with no warm-up or monitoring.
- Purchased or scraped lists with no source or opt-out process.
- Generic, fear-based templates for CISOs and technical evaluators.
- No sample copy and no reporting on bounces and spam complaints.
Cold email agency for cybersecurity vs freelancer vs in-house

|---|---|---|---|
| Typical cost | $1,000 to $7,500+/mo | Lower; hourly or project-based | Salaries plus data and tools |
| Skills covered | List building, copy, deliverability, reporting | Usually copy or list building | Depends on hires; usually sales-led |
| Speed to start | 2 to 4 weeks | Days | 1 to 3 months to hire |
| Best for | Outbound pilots and scaling | Defined sequences, small budgets | Vendors with a mature sales motion |
| Main risk | Little security product depth | Capacity and continuity | Ramp time and turnover |
What does a cold email agency for cybersecurity do?
A cold email agency for cybersecurity runs outbound email to security buyers on behalf of vendors. It builds target account lists, writes short technical messages, sets up and warms sending domains, sends and monitors sequences, handles replies and books meetings. For security products the work also means credibility with CISOs and engineers, careful claims, and respect for data and email rules in each market where recipients sit.
Cold email agency for cybersecurity FAQ
What is the best cold email agency for cybersecurity?
Leadium is our top pick because it lists cybersecurity among its industries, holds 5.0 across 90 Clutch reviews and runs email, phone and LinkedIn together. Callbox, LevelUp Leads, Purple Sales and A-Sales also list security work. Seven of the 14 agencies we track list cybersecurity clients for this service.
How much does a cold email agency for cybersecurity cost?
Across the 14 agencies we reviewed, the median minimum is $1,750 a month, with 50% in the budget tier, 33% between $1,000 and $5,000 and 17% above $5,000. Callbox quotes $12,000 to $80,000 a year and LevelUp Leads reviewers cite $4,000 to $7,000 a month. Confirm what each quote includes.
How long does cold email take to book meetings for a security vendor?
Expect the first replies within two to four weeks of launch, after one to three weeks of domain setup and warm-up. Meaningful meeting volume usually takes two to three months of testing, because security buyers are cautious and need to see relevant messages repeatedly.
Is cold email to CISOs legal?
Rules depend on where recipients are. CAN-SPAM in the US requires honest sender details and a working opt-out, while GDPR and PECR in the UK and EU set stricter conditions on business email and data. This is general information, not legal advice, so ask any agency how it handles consent and opt-outs.
Do cybersecurity vendors need a specialist cold email agency?
A specialist helps, because technical buyers spot shallow messaging quickly. Seven agencies in our directory list cybersecurity clients, though few show security case studies. Choose one with security evidence and supply product expertise yourself, or pair a security-aware demand agency such as Gripped with an outbound partner.
How do I protect deliverability when sending cold email for a security product?
Send from separate domains, never your primary one, authenticate them, warm them gradually and keep volume and spam complaints low. Google's sender guidelines set clear expectations for authentication and complaint rates. Ask the agency how it monitors inbox placement and what it does when a domain is flagged.
Should I do cold email in-house or hire an agency for a security product?
Hire an agency if you need to test outbound quickly without recruiting SDRs, and go in-house once messaging and meeting quality are proven. An agency can set up domains and sequences in weeks, while an in-house team gives you product depth and control but takes months to ramp.
Which cold email agencies work with UK and EU security buyers?
A-Sales in Stockholm lists cybersecurity and offers GDPR, SOC 2 and ISO 27001 documentation on request, and Gripped in London lists security but not cold email. Other agencies can email UK and EU recipients, but must follow UK GDPR, PECR and GDPR. Ask where lists are sourced and how opt-outs are recorded.
