Check an email before you send it

Looks over an email’s HTML and says what is likely to go wrong: things Gmail, Outlook or Apple Mail strip or ignore (scripts, forms, flexbox, SVG, positioned elements, very large messages) and links that go nowhere (empty, #, placeholders like example.com, local addresses, plain http, text that shows one address and links to another). Send the html, or a template_id (and optionally a version). With live: true it also opens each https link, up to 25, to see whether the page still exists; sites that refuse automated visits are reported as “could not check”, never as broken. Findings are error, warning or info. ok is false when there is at least one error.

Required scope: templates:manage

Example

curl -X POST 'https://api.sendsend.email/v1/templates/check' \
  -H "Authorization: Bearer $SENDSEND_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
  "html": "<a href=\"#\">Verify</a>",
  "live": false
}'
