I’m building a quite sophisticated messaging system, and I want my users to know if an email that was sent through Sendgrid was sent to an invalid address or bounced back by the receiving server. I can’t see any existing plugin options that address this.
Does anyone have experience of how to do this?
Is it easier in other systems such as SendinBlue or ClickSend rather than Sendgrid?
I don’t mind doing some work to get it going, but a pointer to a direction that works would be much appreciated!
