Quick take

  • Connect unlimited inboxes, warm them up automatically and send cold email sequences that stop when someone replies.
  • Sending plans are $47, $107 and $358 a month, or about 20% less billed yearly. Leads and AI credits are a separate plan from $47 a month.
  • Bundles that combine sending, leads and AI agents start at $94 a month, or $85 billed yearly.
  • Reviews praise how easy it is, but billing complaints and campaigns landing in spam despite warmup come up often.

What is Instantly?

Instantly is a cold email tool. You connect as many email inboxes as you like, and it warms them up by sending and replying to emails in the background, so your messages are less likely to land in spam. Then you write a sequence (a first email plus follow-ups) and it sends it to your list, spreading the emails across your inboxes and stopping when someone replies.

On top of sending, it has a database of 450 million B2B contacts to find leads, email verification, a shared inbox for replies called Unibox, a simple CRM and AI agents. The AI can research each lead, write personalised first lines, sort replies into interested and not interested, and on the bigger bundles reply for you. Sending plans don't limit how many inboxes you connect, which is why agencies like it.

The catch: leads and AI run on separate credit plans, so the real cost is often double the sending price. Billing complaints, like charges after cancelling, come up a lot in reviews, and some users say warmup scores look healthy while campaigns still land in spam. Cold email laws differ by country, so check the rules where you're sending.
