Guides

Build with Mail.

Six chapters from your first DNS record to a debuggable production sender. Each chapter assumes you've finished the previous one but cross-references back, so jumping in mid-series works.

Mental model

Sender → recipient

Mail is a transactional email service. You verify a domain (DKIM-signed, SPF-aligned), author a template (Handlebars), then call POST /workspaces/:ws/templates/:name/sendwith a recipient + data. We deliver via your verified sender, signed by your DKIM, with bounce + complaint tracking attached.

What we're not: a marketing email tool. No campaign send, no opens-clicks-funnels analytics, no list-management primitives. If that's what you need, an ESP like Mailchimp / Customer.io is the right shape. Mail is for the messages your product sends — order confirmations, password resets, invite links, account notifications.
