No app passwords, no DNS copy-paste. Authorize once and warming runs on its own.

We check your authentication

All passingWarming starts automatically
Personas begin engaging your mail like real recipients. The dashboard tracks every open, reply, and spam rescue live, and tells you the moment the domain is ready for outreach.

Hidden by default
Keep warming out of your inbox
Choose Inbox visibility when you connect, and change it anytime in Settings. On Hidden (the default), every warming email is auto-labeled and archived the instant it arrives, so your real inbox stays exactly as it was.
Inbox visibility
Hidden moves warming mail to a label/folder so it doesn't clutter your real inbox.
Hidden
Recommended, clean inbox
Visible
Show warming mail in your inbox
Every thread the personas exchange is written fresh and grounded in your business, never templated. See how warming works.
