Email Notifications (Transactional)
Automated emails triggered by user actions, like welcome messages, password resets, and order confirmations.
Transactional emails are triggered by events in your application: a user signs up (welcome email), resets their password (reset link), completes a purchase (receipt), or gets invited to a team (invite link). Unlike marketing emails, transactional emails are expected and time-sensitive.
Services like Resend, SendGrid, and Postmark handle email delivery, ensuring your messages reach inboxes instead of spam folders. You write the email content (usually HTML templates or React components), configure a verified sending domain, and call the API when the event fires.
For vibe coders, transactional email is a common feature that AI handles well. You describe the trigger ("send a welcome email when a user signs up") and AI generates the email template and API call. The key decisions are choosing the right service, verifying your domain, and designing emails that render correctly across email clients.
