The ‘Reply-To’ Email Address is determined by the ‘Default Incoming’ checkbox in the relevant Email Account settings.

Prerequisites:

Ensure that you have an email address registered in the ‘Email Account’ section for the desired email address, such as ‘[email protected]‘.

Steps:

1. Open the record for the email address ‘[email protected]‘ in the ‘Email Account’ section.
2. Check the ‘Enable Incoming’ checkbox, followed by the ‘Default Incoming’ checkbox.
3. Enabling the ‘Default Incoming’ checkbox will automatically assign this email as the ‘Reply-To’ address (see the sample screenshot below).
