Better Error reporting: Pass through Mailchimp errors to FE

[MaxwellGarceau]

Is your enhancement related to a problem? Please describe.

Problem

Currently, Mailchimp errors will not be displayed on the FE. It is assumed that if a request is not a 200 response and there are no errors in the body that the email address is invalid.

However, I ran into a 400 error while testing because "max.garceau+phonenumberinvalid@10up.com has signed up to a lot of lists very recently; we're not allowing more signups for now".

This error was not visible on the FE. If a user ran into a different 4** error related to Mailchimp anti-spam (or another limit) it would be a bad user experience.

Solution

Admin View (could also show a logged out user)

• Update the error message check to also check for $body['detail'] and display the detail property as an error message if exists.
• Double check Mailchimp API docs to ensure that error messages are not transmitted via another property on the response

User View

• Give a generalized error message that lets a user know their subscription was not successful.
  • Maybe pull in the contact information from Settings > General > Administration Email Address?

Designs

No response

Describe alternatives you've considered

Another solution would be to generalize the catch all email validation. For example, "Email Address: Please fill out a valid email address, choose another email address, or wait a little bit before your next submission".
