Where do replies to my SES emails go?

To the Reply-To address, or the From address if there's no Reply-To. Unless your domain receives email, those replies bounce. HelloBox sets up SES receiving and shows the replies in a shared inbox.

Where do replies to my Resend emails go?

To the Reply-To or From address. Turn on receiving for your domain in Resend and connect it to HelloBox to read and answer those replies as a team.

Should transactional emails use a no-reply address?

It's better to use an address customers can answer, like support@yourdomain.com, and read replies in a shared inbox such as HelloBox.

Where do replies to transactional emails go?

Updated November 9, 2026

Short answer

Replies to transactional emails go to the address in the Reply-To header, or the From address if there's none. With Amazon SES or Resend, that address usually has no mailbox behind it, so replies bounce or disappear. Set Reply-To to an address on your domain such as support@, and connect your provider to HelloBox so those replies land in a shared inbox your team can answer, without changing how your app sends.

Where replies actually go

When someone presses Reply, their mail client uses the Reply-To header if your email has one, and the From address otherwise. If you send from [email protected] through SES or Resend and nothing receives mail for that domain, the reply bounces, and you never hear about it.

Those replies are some of the most valuable mail you get: a customer stuck on a password reset, a question about an invoice, a lead answering an onboarding email.

Catch every reply

Send from an address people can answer, or set Reply-To to one, for example [email protected].
Connect Amazon SES or Resend to HelloBox. It turns receiving on for your domain and shows incoming mail in an inbox.
Share the support@ mailbox with your team, assign conversations, and reply from the same address through your own provider.

From: Acme <[email protected]>
Reply-To: Acme Support <[email protected]>

Your app's sending doesn't change. HelloBox only adds receiving and the inbox, and AWS or Resend keeps billing you for volume directly.

Why not just use no-reply?

A no-reply address tells customers you don't want to hear from them, and replies that bounce can hurt how mailbox providers see your domain. An answerable address costs nothing once your domain receives mail, and HelloBox's spam filtering and rules keep automatic replies out of the way.
