Error in Webflow > Mailerlite scenario - help!

Hey all,

Just launched my website last week but I’ve hit an error in my Webflow to Mailerlite subscription scenario. I tested it several times before launch and it worked, but the first real submission has caused an error, and I don’t know what it means.

All of the fields that need to be filled are filled. Any idea what this error is exactly and what I can do to fix it?

Any help is very appreciated. Thanks so much!

Update: This is really strange. I made a new identical scenario, tested my own address, and it worked. Then I tested with the email address that initially caused the error, and it failed. Then I tested with a completely made up address, and it WORKED. What’s going on?

Here’s a comparison:

Nowadays this is a common issue from Mailerlite. Their system is not accepting certain types of email addresses.

Just raise this issue with their support team. They should be able to guide you.


That’s interesting to know. What a pain. Thanks very much for your help!
