AnymailUnsupportedFeature SendGrid does not support multiple reply_to addresses

---

It looks like Sengrid supports multiple "reply to"s (see changelog).

However, Anymail still documents a single reply_to as a Sendgrid limitation, see docs.

It looks like this is still limited by Anymail here, but when having multiple "reply_to"s, the reply_to_list should be used instead.

Thanks for reporting this and providing the pointers to SendGrid's docs.

You've correctly identified exactly where to fix it. Want to open a PR to switch Anymail from reply_to to reply_to_list?
