@johnhbenetech it seems that it's no longer allowed to set 'from' address when sending out emails with Sendgrid (it still returns code 202, the error message can probably be found in the Sengrid app). I will try setting 'Reply-to' header, if that doesn't work perhaps we can include something like 'Please reply to user@thatsentfeedback.net' in the body of the message?

@johnhbenetech as per docs - the sender identity has to be verified https://sendgrid.com/docs/for-developers/sending-email/sender-identity/

@jkondrat

Yes, let's just include it in the body, The from address can be 'feedback@benetech.org'

@johnhbenetech I was able to use reply-to header, is this sufficient? the delivered email looks like this:

@jkondrat looks good
