Cold email infrastructure with self-healing deliverability

Peeker is cold email infrastructure for agencies and outbound teams. It provisions Google Workspace and Microsoft 365 inboxes, monitors deliverability 24/7, and auto-heals issues before they kill campaigns. Alternative to Instantly, Smartlead, and Lemlist inbox management.


How does the auto-heal actually work when an inbox starts getting flagged, do you swap domains or just tweak sending patterns on the fly?
How does the auto-heal actually work when an inbox gets flagged, does it spin up a fresh one or try to warm the existing domain back up?
Set up a fresh Workspace in minutes and the deliverability alerts actually caught a DNS issue I would have missed. The auto-heal piece is what sold me, no more babysitting inboxes at 2am.
