Mailchimp error: Invalid Resource - Please provide a valid email address

Symptoms

When using the Mailchimp Add/Update Subscriber action in your Zaps, you see the error message "Invalid Resource - Please provide a valid email address". You may see this error when setting up a Zap or in the details of a Zap run in your Zap history.

Causes

This happens when:

• The mapped field does not contain a valid email address.
• The mapped field contains more data than just an email address, such as the email address and a telephone number.

How to fix it

To fix this issue:

• If the issue only occurs when you test the step, change the value to provide a valid email address.
• If the mapped field contains more information than just an email address, add a Formatter step after it to:
  • Extract the email address or, 
  • Split text to isolate the email address.
• If the mapped field contains data in an unexpected format, you can use regular expressions (regex) to extract the email address. 
• Before continuing to your Mailchimp step, add a filter to your Zap to ensure an email address exists in the field.
