Frequently asked questions
What people usually want to know before signing up for Instantly.ai.
How many inboxes should I use?
Rule of thumb: 1 inbox per 50 emails/day. 100 inboxes = 5K/day capacity.
Does Instantly guarantee inbox delivery?
No tool can — but warmup + rotation significantly improves rates.
Is cold email still legal in 2026?
In the US and UK yes, with an opt-out link and physical address. In the EU, legitimate interest justifies B2B contact, but documentation matters.
How many emails per inbox per day is safe?
40–60 is the current ceiling for a warmed Google Workspace inbox. More than 100/day is a deliverability trap, not a growth lever.
Will this get my main domain blacklisted?
Only if you ignore warm-up and reply monitoring. Use a secondary domain pointed to your main site to keep risk off the primary.
Bottom line
Should you use Instantly.ai?
The default pick for high-volume cold-email operators. Low-volume teams should pick Snov or Lemlist instead.
