Instantly.ai alternative
Instantly sends the campaign. We decide what deserves to be sent.
What Instantly.ai is
A cold outreach platform: inbox rotation, warmup, sequencing and deliverability tooling built for sending at volume.
Sending infrastructure. Inbox rotation and warmup are genuinely hard and they do them well. We do not send campaigns at all.
Pick Instantly.ai when: You need to run and manage sequences across many inboxes. That is their product and it is not ours.
You want a gate in front of the sender, so dead addresses never leave your outbox and your domain stops absorbing the bounces.
Side by side
| Instantly.ai | Verdict | |
|---|---|---|
| Sends campaigns | Yes, at volume | No. We gate what you send |
| Verification timing | Bundled, before send | Real SMTP probe, before send |
| Catch-all handling | Marked valid | Marked unverifiable |
| Use together | — | Yes. Gate the list, then send with theirs |
Instantly is priced per seat and sending volume. Free and MIT, or $59/mo hosted.
The honest summary
Verdict has no contact database and does not send campaigns. It opens an SMTP connection to the receiving server, asks whether the mailbox exists, and reports what the server said. When the server refuses to answer, or the domain accepts every address, it says so instead of guessing. That is the whole product, it is MIT licensed, and it runs on your own machine so the list never goes anywhere.
Try it on a real list
Paste up to 500 addresses. Free, no signup, nothing stored. The fairest test is your last campaign's bounce list, since you already know which ones failed.
