Tags

How it works

Attach identifiers to an email for later correlation. Pass tags as name/value pairs when sending. Email webhook payloads expose tags as an object.

Example

{"tags":[{"name":"category","value":"receipt"}]}

Things to know

You can set at most 48 user tags. Opensend reserves two SES tags for its email and team identifiers. SMTP has no special tags header; use REST when tags are needed.
