Email overview
Why a self-hosted site needs a way to send email, which providers it supports, and what the "log" and "none" settings do.
Amazon SES
Send your site's email through Amazon SES, with the settings, the AWS set-up that has to happen first, and what the log says when SES refuses a message.
SMTP
Send your site's email through an ordinary mail server, with the settings, working examples and notes for common mail accounts.
Resend
Send your site's email through Resend, with the settings, the domain step and what the log says when a message is rejected.
SendGrid
Send your site's email through SendGrid, with the settings, the sender or domain step and what the log says when a message is rejected.
Mailgun
Send your site's email through Mailgun, with the settings for its US and EU regions and a working example for each.
Postmark
Send your site's email through Postmark, with the setting, the message stream the site always uses, and a working example.
Send announcements through a different service
Send login links through one provider and announcements through another, by repeating any email setting with ANNOUNCEMENT_ or TRANSACTIONAL_ in front.
Sender addresses, sending speed and testing
Set who your email comes from and where replies go, pace announcements to suit your provider, and check that email works before members depend on it.
