Peeker vs Zapmail
Questions

What teams ask before switching from Zapmail to Peeker.

Zapmail's plans run from $39 a month for 10 mailboxes ($3.90 each) to $299 a month for 100 ($2.99 each), and its ZapShield blacklist add-on costs $3 per domain per month. Peeker's Google inboxes cost $3.50 each up to 249 inboxes, $3.00 from 250 and $2.80 from 1,000, with monitoring and automatic swaps included.

Zapmail's ZapShield add-on gives a free replacement domain when a domain gets blacklisted. Its site does not describe detecting or replacing burned mailboxes. Peeker tracks every inbox and swaps burned ones automatically.

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.
