Hello! I’m having difficulty getting your plugin to add emails to my Sendgrid list. First, I put in my API key and sent a test email. It worked fine, so I designed a popup and plugged in the same email. It didn’t work! Why is this happening? What can I do to make it work?
I’ve checked popup at your website and it seems to work
Have you got “Empty or invalid email” error after entering email second time?
By default “Email error message” and “Email exists error message” text is set to “Empty or invalid email”.
This is done for security reasons. You can change these settings if necessary.
