Adeline AI plans warm-up per mailbox and flags emails at high spam risk.
The short answer
AI assistant, in one look.
Warmerly has no deliverability assistant, while Warmy has Adeline, which plans warm-up for each mailbox, flags emails at high spam risk and suggests what to review. Warmerly's AI writes campaign openers using credits, and it runs an MCP server for Claude and ChatGPT. Warmy's Agents page says its examples are analysis and suggested next steps, not automatic remediation; its Adeline page says Adeline adjusts the plan itself. Last checked 22 October 2026.

- Whether Adeline sends email itself or only advises
- How much a person can override
- The accuracy of its spam-risk flags
- Whether you can override or undo Adeline's changes
- Which plans include the AI connections

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Keep a person in the loop
Treat any assistant's advice as an input. Warmy's Agents page says its examples stop at suggested next steps, while its Adeline page says Adeline adjusts the warm-up plan, so ask what it changes on its own.
Ask what is measured
Warmy's headline figures have no stated method, so ask how they are produced before you rely on them.
Check whose hands are on the controls
Adeline adjusts volume and pace itself, per its page. Warmerly's ramp is published and changes only by the rules you can read.
Keep the AI claims in perspective
Both products use AI. Warmy's superlatives have no method on the page, so test it in the trial.
