Forwarding email out

Important info about email forwarding out of HEY.

Here are some aspects of email forwarding that you should know when configuring HEY to forward your email out, especially if you’re doing this after closing your paid account or if you’re adding an extension that forwards to an external address in your HEY for Domains account.

Let’s start with our general advice: you shouldn’t rely on forwarding alone for critical or very important emails. If you close your account, you can set up forwarding so you won’t miss anything if someone accidentally sends emails to your old address, but this is not meant to be actively used in perpetuity. You should move any important services where you still have your account configured to use an active email address instead.

If you have a HEY For Domains account and you need to receive critical mail in any of your domain addresses, configure it as a regular user or extension instead of an external extension. As a regular user, you can still forward to an external address while being able to log in and access emails directly.

Here’s why:

  • HEY won’t forward emails classified as spam. If our spam filters determine that an email is spam, we won’t forward it out. Although they’re rare, false positives happen and we might flag a legit email as spam and skip forwarding it.
  • Forwarding might break email authentication. Depending on the sender’s domain configuration and the receiver’s email service, an automatically forwarded email might not arrive, or it might be flagged as spam when it reaches the recipient. The reason is that email forwarding can break DMARC. To help with this, we implement ARC authentication for forwarded emails. This preserves SPF and DKIM authentication for the original emails and, thus, reduces the likelihood that forwarded messages are flagged as spoofed. However, ARC doesn’t always work, as the receiver might decide not to trust the ARC headers. This is very unlikely, but it might happen.
