The SMTP dialog has presets for Gmail, Microsoft 365, Zoho, Yahoo, iCloud, Fastmail, GMX and Yandex, or choose Other or custom server.

Use Google or Microsoft whenever you can. SMTP can only send: it can't read replies or confirm delivery, so it can't run follow-up campaigns.

Default sender and sharing

• Set one mailbox as your Default sender.
• Under Who can use it, share a mailbox with teammates for sending, reading conversations, or both. See Share a mailbox.

What Reach-book.com reads
