Introduction

cmdsend is a transactional email API built for developers. Verify a domain, generate an API key, and send — that's the whole setup.

One API call

Send transactional email with a single request — no SMTP config, no queues to manage.

BYODKIM by default

One DKIM TXT record instead of three CNAMEs, plus a custom MAIL FROM domain so SPF aligns for DMARC.

Simple auth

Bearer API keys with scoped permissions — emails:send and emails:read.

Delivery visibility

Every send, delivery, open, click, bounce, and complaint tracked and queryable.

Send your first email

Once you have an API key and a verified domain, sending is one call:

Terminal

curl -X POST https://cmdsend.com/v1/emails/send \
  -H "Authorization: Bearer cmd_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "from": "hello@yourdomain.com",
    "to": "user@example.com",
    "subject": "Hello from cmdsend",
    "text": "This is a test email."
  }'
