What are Fallback Domains?

last updated July 3, 2024

Fallback domains are only available to Small Business and higher users.

Introduction

As your business grows, you may find that it becomes necessary to hold multiple domain names that all represent the same entity. In this situation, what happens when someone sends you an email to one of your alternate domains? This is where Fallback Domains come in handy.

What are Fallback Domains?

Fallback domains are also known as alias domains or secondary domains. When you send a message to a domain but the recipient does not match any existing address, the message will be redirected to a fallback domain. An example of this would be if you had two domains, "example.com" and "alternate.com", and assigned the latter as a fallback for the first. If you send a message to "[email protected]", Mango Mail will first check to see if an address with that name exists. If not, instead of bouncing the message, Mango Mail will redirect it to "[email protected]" and check to see if there is an address there. Ultimately, this allows you to receive emails from any alternate domain and redirect them to your main one.

Fallbacks are "1-level deep"

When we say that fallback domains are "1-level deep", we mean that you cannot have a fallback that points to a domain with another fallback. This would be dangerous as it could result in an endless loop. Instead, you'll want to make sure you configure your alternate domains to fall back directly to the main domain and not another alternate name.

How do I assign a fallback?

  1. Log into the Mango Dashboard and click on the "Domains" tab.
  2. Click on the domain you wish to assign a fallback.
  3. Switch to the "Fallback Domain" tab.
  4. Enter the domain you would like to assign as the fallback domain and click "Assign fallback".

Conclusion

Now you can configure all your alternate domain to fall back to your main domain, so you can receive mail from every face of your business.
