Email channel-level overrides | Courier's Help Center

The email channel override allows you to set the subject, reply to, from, cc, and bcc email addresses, as well as the HTML and text via an override that will apply to all your email channels* within a template.

*Note: attachment overrides done at the channel level will only work with Mailgun and AWS SES currently. To add attachments to other providers, see integration level overrides.

Here is the override data structure for the email channel override:
