Reply-To is a header that tells email clients where replies should go. Learn how Reply-To works and why businesses use it for routing.
Reply-To is an email header that specifies the address where replies should be sent. While the “From” address is what recipients see as the sender, Reply-To can direct responses to a different mailbox.
Businesses use Reply-To for routing and workflow. For example, a campaign might be sent from a branded address but replies should go to a shared inbox monitored by a team, or to a specific rep handling responses.
Reply-To should be used carefully to avoid confusion. If Reply-To sends replies to a different domain or unexpected address, it can reduce trust. Consistency between From, Reply-To, and branding helps maintain credibility.
