Building Transactional Emails with the SendMesh API

What are Transactional Emails?

Transactional emails are triggered by user actions: password resets, order confirmations, welcome emails, verification codes. They have high open rates (60-80%) because recipients expect them.

Sending with SendMesh

curl -X POST https://api.sendmesh.co/v1/emails/send \
  -H "Authorization: Bearer sk_live_xxx" \
  -d '{"to":"user@example.com","subject":"Welcome!","html":"<h1>Hello!</h1>"}'

Template Variables

Use Handlebars syntax for dynamic content: {{firstName}}, {{orderNumber}}. Create templates once, reuse everywhere.

Webhooks

Track every event: delivered, opened, clicked, bounced. SendMesh sends HMAC-signed webhooks to your endpoint in real-time.
