If you are getting an error "Missing Arguments" when trying to subscribe to your forms which are integrated with AWeber, please read this article:
Unfortunately, role based email address such as support@, team@, sales@ are not accepted via the AWeber API. This error message is the default error when the submission is rejected by the AWeber API - you'll get a "Missing Arguments" error.
As we use the Aweber API, their API will block any role based email addresses. They have a support article on this as well: https://help.aweber.com/hc/en-us/articles/204029356-Why-is-my-email-address-blocked-
If you test your forms with personal emails such as yourname@gmail.com = you should find these are accepted.
This limitation is not something we can fix from our side - it's a limitation or block imposed by AWeber.
