Add batch sending support for Resend #356

Closed medmunds closed 6 months ago

medmunds commented 6 months ago

Resend recently announced a new batch sending API. Anymail should add support for it.

Resend's batch send API basically takes an array the same payload structure used for the regular send API. So it:

Wouldn't support Anymail's merge_data (because Resend doesn't support ESP-rendered templates even for regular send)
Would support Anymail's merge_metadata (batch send supports custom headers, which Anymail uses for metadata and tags with Resend)
Doesn't support attachments "yet" (need to test if attachments field causes error, or is just silently ignored right now)

(Released in Anymail 10.3)
