Warm up new domains and keep cold email out of spam with daily placement tests
InboxPilot warms new sending domains with a managed network of real inboxes and tests where your emails land every day.
Agencies use it to bring a fresh domain to a safe sending volume in about five days and to catch a placement drop before a campaign suffers.
It works with Smartlead, Instantly and any SMTP sender, and shows the result per mailbox so you know exactly which one to rest.

Works well: Per-mailbox health made it obvious which mailbox to rest.
Could be better: Reports are not white-label on the Studio plan.
Reply from InboxPilot
Thank you for the detailed feedback. We have noted the limits you mention and will share changes on the product page.
Used for: Daily placement tests across forty mailboxes.
Works well: The trial was long enough to see a real result.
Could be better: You still need a separate sending tool.
Does warm-up work with Google Workspace and Microsoft 365 mailboxes?
