Forward email to Slack / Hostinger

Forward a Hostinger Email address (support@) to a Slack channel

In Hostinger's hPanel, a forwarder sends every email that reaches a Hostinger Email mailbox on to another address. Create one from support@ to your RelayMail address, click the verification link, and each new email starts a Slack thread. Replies from the thread go back to the customer as email.

Steps

  1. 1

    Create the forwarder

    In hPanel go to Emails, click Mailboxes next to your domain, open Forwarders and select Create forwarder. Choose the support@ mailbox as the source and enter the forwarding address from your RelayMail setup page (inbox-...@relay.relaymail.app) as the destination.

  2. 2

    Keep a copy or not

    Leave Save copies of forwarded emails on to keep a copy in the Hostinger mailbox. Turn it off and forwarded emails are deleted from it. Then select Create.

  3. 3

    Click the verification link

    Hostinger sends a verification link to the destination address, and the forwarder is not finished until someone clicks it. Until forwarding is confirmed, RelayMail passes that email on to the email on your Slack account: open it there and click the link.

  4. 4

    Send a test email

    Email support@ from an outside account. When it arrives, RelayMail confirms forwarding by itself and the email appears in the channel as a thread; reply there and the sender gets your reply by email.

Confirming the forward

Hostinger sends a verification link to the forwarder's destination. RelayMail passes it on to the email on your Slack account until forwarding is confirmed, so you can click it from there. Replies you write in the Slack thread go out from noreply@relay.relaymail.app with Reply-To set to your support address, so the customer's answer comes back through the same forward into the same thread. To send replies as support@ itself, verify your domain in RelayMail (see the custom domain guide); that adds sending records for RelayMail and does not change where your inbound mail goes.

What to watch for

  • The source has to be a Hostinger Email mailbox, picked from the list when you create the forwarder.
  • Forwarding to RelayMail is what Hostinger calls an external forwarder: the destination domain does not use Hostinger mail.
  • If your domain is at Hostinger but its mail runs elsewhere (for example Google Workspace), Hostinger suggests a filter in that mail service instead of a forwarder. Use the guide for the service that receives your mail.

Questions

Does a Hostinger forwarder keep a copy of the email?

Only if Save copies of forwarded emails is on. Hostinger turns it on by default; with it off, forwarded emails are deleted from the original mailbox.

Why is my Hostinger forwarder not working yet?

Hostinger finishes a forwarder only after the verification link sent to the destination is clicked. RelayMail passes that email on to the email on your Slack account.
