Direct Mail:Reply-to address FAQ

Last Updated:Oct 29, 2025

How do I verify a reply-to address?

In the Direct Mail console, click Sender Addresses > Create Sender Address. The reply-to address that you set is used to receive replies to emails sent from the console and through API calls.

The reply-to address must be a valid email address and must be verified before it can be used. Log on to the mailbox for the reply-to address, find the verification email, and complete the verification. If you do not receive the verification email, check your spam folder.

How do I receive email replies?

Direct Mail focuses on sending emails and does not provide an email receiving service, such as a corporate mailbox. However, you can set a reply-to address to forward replies to a specified address.

  • For emails sent from the console and through API calls, set the reply-to address when you create a sender address on the Sender Addresses page. The reply-to address must be verified before use.

  • For emails sent over SMTP, specify the Reply-To address in your SMTP call code.

Note: The verification link in the verification email is valid for 10 minutes. Complete the verification within 10 minutes after you trigger it. Do not click Verify Reply-to Address repeatedly. You can click it only once every 10 minutes.

Note
  • The reply-to address feature works by setting the Reply-To address in the message header. Whether you receive a reply depends on whether the recipient's mailbox supports the Reply-To field in the standard SMTP protocol.

  • When a recipient clicks Reply, the reply-to address must appear in the address field for the reply to be received. If only the sender address is displayed, the recipient's mail client does not support this feature, and the reply is sent to the sender address instead of the reply-to address. In this case, specify the email address for future communication in the body of the email.
