Using Disposable Addresses With Custom Domains on Gmail
Posted October 23, 2017 in Tech Tips

As we mentioned in one of our previous posts, Gmail lets you use an infinite number of addresses with each of your accounts. This means that, while you might be limited to six Gmail accounts in Kiwi for Gmail, each can have many additional addresses feeding into it. You can use these "disposable addresses" to automatically assign labels to mail coming from different people or organizations. While setting up an infinite number of email addresses is easy if you’re using a normal @Gmail account, it’s a bit more complicated when you’re using a custom domain (not a typical one).

Let’s say you are using Kiwi for Gmail or our enterprise version, Kiwi for G Suite, with your custom business domain. You or your company have probably already signed up with a Google service that merges your custom personal or business domain into Gmail and G Suite. You’re probably using “G Suite for Businessand/or “Google Domains.”

Consider this situation: Chris owns a small business called “My Business.” The domain is “” and he receives his email at the address “Chris@MyBusiness.” This means all of Chris’ mail -- messages from clients, newsletter subscriptions, and junk email -- goes to that address.

Chris loves using Kiwi for Gmail. And because Chris is saavy, he uses labels to identify and sort his email. However, it’s still all in that one account. And things are getting kind of crowded there. Suppose Chis sets up two Gmail accounts under his domain. He has “” and” Going forward, only the mail Chris really wants to see will be in his account. Everything else will be in “” He might use rules and labels to sort the mail in catchall.

This is a time when you'll be glad that Kiwi for Gmail and Kiwi for G Suite handle up to six Gmail accounts because you’re going to need at least one more account available.

Chris needs to go to the domain registry, at Google or elsewhere, to set it up so that all all email addressed to “” goes to that email account. If your company is larger and uses a custom domain, you may not have access to make changes in the domain registry yourself. In that case, this would need to contact someone with adminstrative access and have them do it for you.

Everything else is sent to “” And Chris’ Kiwi for Gmail or Kiwi for G Suite is set for those two accounts: and

Chris can use a period and a phrase to identify where mail is coming from. He could use addresses like,,,, and so on. All of these would be routed by Chris’ domain registry to “”

We’re indebted for this tip to a person known only as “TVJames” who left a comment about this on a blog post about using Gmail way back in 2007.

TVJames’ comment noted that this method can raise a problem occasionally when you are visiting a shop and you are asked for your email address.

“It does confuse people when you're standing there assuring them, ‘Yes, my e-mail address is really ‘’” he wrote, recalling what he had said on a recent clothes-shopping trip. “‘Just type it in already.’”

But, he added, if that email address leads the store staff to “believe I'm a not-so-secret shopper and gives me better service, I'll take it.”
