When using Gmail’s Send Email or Reply to Email action in your Zaps, you see the error message "To send a message, it needs at least one To, Cc or Bcc 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 from the previous step in either the To, Cc, or Bcc field is blank.
- No email address (static or dynamic value) is added to the To, Cc, or Bcc field field.
Gmail requires at least one email address in the To, Cc, or Bcc field to send an email.
How to fix it
To fix this issue:
- Add a static or dynamic value for the email address to the To, Cc, or Bcc field.
- If you are using a mapped field to dynamically add the email address, ensure the data from the previous step is consistently sent to the Gmail step, or replace the current mapped field with one that consistently provides an email address value.
- Re-test your previous step to ensure you have the most current fields.
- If you cannot change the current mapped field, you can either:
- Add a step to set a default value as a fallback whenever your mapped field does not have any data.
- Add conditional logic using a filter or branching logic with paths to your Zap. This will allow you to define what the Zap should do if the To field does not receive data from the previous step.
