关于 MailboxWatch
MailboxWatch is an independent price tracker for cold email infrastructure. It compares 20 mailbox and SMTP offerings from 17 providers (Google Workspace and Microsoft 365 resellers, shared and private SMTP) on one apples-to-apples setup: 30 mailboxes on 10 domains, monthly billing, domain costs included. Prices come from each provider's own pricing page, get re-checked regularly, and every change is logged. Free to use, with a weekly price-change email. Rankings sort by price only.
