Mailbox compatibility · No Outlook/Microsoft App Passwords
Mailbox Compatibility: Connect up to 15 existing mailboxes ($0 extra) via standard SMTP/IMAP + App Passwords (Gmail, Google Workspace, Zoho, Hostinger, Titan, Fastmail, or any custom SMTP/IMAP server). Providers that block standard IMAP App Passwords (such as personal Outlook/Hotmail or OAuth-only Microsoft 365 tenants) are not supported via App Password. Your provider’s plan and administrator must allow SMTP/IMAP access. The free trial includes one mailbox.
Google Workspace inboxes, automatic SPF/DKIM/DMARC, and website forwarding. Provider prices pass through with zero Maestyr markup.
