AI Warmup & Deliverability
AI Warmup trades real-looking mail with a pool of mailboxes, a health score watches every one, and campaigns step away from a mailbox the moment it slips.
Warm, write, watch, check, react. Each one is a page in the app.
Your mailboxes send to and reply to mailboxes in the warmup pool. Anything that lands in spam is moved to the inbox, marked read and answered, which teaches providers that your mail is wanted.
Answer a few questions once and the AI writer drafts warmup emails about the things you really email about, for every mailbox. Or use your own templates, or mix both with the built-in library.
Health starts at 100 and loses a point for each warmup email that lands in spam over the last 14 days, plus a penalty when campaign bounces climb. Below your limit, campaigns stop using the mailbox. Warmup keeps going until it recovers.
MX, SPF, DKIM, DMARC and blocklists for every sending domain, with the exact record to add when one is missing. Re-check all with one button.
Inbox placement compares how many people still engage at Google, Microsoft, Yahoo and others against each provider's own baseline. When one collapses, it tells you what to do.
98%average inbox rate across warmed mailboxes
100 − spam landings − bounce penalty = health
One point for each warmup email that landed in spam in the last 14 days. Old landings drop out, so a mailbox can recover.
From campaign bounces, once a mailbox has sent 50 emails.
| Bounce rate | Points off | Scale |
|---|---|---|
| Up to 1% | 0 | |
| 1 to 5% | rises to 25 | |
| 5 to 10% | 25, rising to 60 | |
| 10% and over | 60, the cap |
Example: 2 warmup emails in spam and 0.5% bounces gives a health of 98.

of sending from 40 mailboxes without losing a single domain
Two mailboxes dipped under 90 in March. Campaigns moved off them on their own, warmup kept running, and both were back in a week. I found out from the weekly digest.
