Error Issue (Everything Seems Correct Though)

Hi,

Make sure that the API key, that you copied, is the correct one (and doesn’t have extra spaces or other characters). Most likely, this is an issue.

Also refer to our Mailgun documentation to make sure that you have followed all the steps: https://wpforms.com/how-to-send-wordpress-emails-with-mailgun/

No, that wasn’t the issue. I’ve followed every step precisely though. So, I can’t really think what the issue is.

JUST got it resolved. This isn’t mentioned or indicated in the Mailgun documentation, but I found it in one of the comments below. The API key INCLUDES “key-“. When you click on the key, it highlights the entire code except for “key-“, which obviously implies that you don’t need the key, but you do. Slava, this is probably one of the major issues that people with this error have, so it would probably save you much explanation if this is included in the Mailgun documentation or wherever it needs to be.

I’ve just tested on Mailgun site: it selects the whole key, including key-, as on this page: https://app.mailgun.com/app/account/security
On a page of your particular domain you just need to double click on a key.

I’m glad you’ve resolved the issue.
