Maildoso Review 2026
Last reviewed September 2026 by Théo Pascard
Overview
Maildoso sells cold email infrastructure at volume. Instead of reselling Google Workspace or Microsoft 365 seats, it runs mailboxes on its own SMTP servers and IPs, rotates IPs, sets up SPF, DKIM and DMARC for you, runs placement tests every three days and scores each mailbox's health. Mailboxes export to sequencers such as Instantly, Smartlead, Saleshandy and Apollo. Pricing is what sets it apart: $75 a month for 30 mailboxes and $499 for 1,000, plus $12 a year per domain.

Are Maildoso mailboxes Google or Microsoft?
