Peeker vs MailReach
Questions

What teams ask before switching from MailReach to Peeker.

No. MailReach warms up and tests mailboxes you already own. Peeker supplies the inboxes, tracks their health and swaps burned ones.

MailReach's All-In-One plan costs $19.50 per mailbox per month for warmup and spam tests, on top of what you pay for the mailbox. A Peeker Google inbox costs $3.50 or less per month with tracking included.

If an inbox shows signs of being burned, Peeker pauses it, tells you, and lets you swap it for a fresh one without risking the rest of your inboxes.
