Error 500 setDeliveryFor()

[frm.mwz]

So you're telling me that changing the delivery server does the trick? But why if everything worked so far?

new (not changing), as s/t was stuck/misaligned

oft it is impossible to find the error in a whole system, but resetting one part can do the trick (and oft that one part is done better the next time)

diagnosis from afar is a bit heuristic/imperfect, but each attempt shall cut off one whole error vector (or error space), oft it works

@andreamarucci - also the fact that sendgrid changed its auth system in between the mailwizz versions, so adding the server once again might help.

Ok so I'll try to delete the actual one and recreate the same...

Thanks! No news about the new version?

Well, the problem was related only to sendgrid. Replaced sendgrid with the new API auth system and everything works.

I'm having this same issue with the error 500 when I tried to test email templates.
So i followed the instructions here in this thread posted by andrea and deleted my active sendgrid delivery server.

Now I'm having issues adding sendgrid back as a delivery server. please assist.

• Cannot send the confirmation email using the data you provided.

• Here is a transcript of the error message:
• {"errors":["The provided authorization grant is invalid, expired, or revoked"],"message":"error"}

@TFM - You're using your account password instead of an API key, this is why you get the above error. Go into Sendgrid dashboard, generate a key and use that instead

@twisted1919 Thank you sir! Worked like a charm and now my test campaign email works perfectly as well!
