How to Add a Different Domain’s Email Alias to GSuite & Send As a Different Email Address from Gmail from a Different URL

It used to be easy to reply from a different domain’s email account in GSuite’s Gmail – you’d just confirm you had access, and a few clicks later you’d be good to go! No longer! Now it’s an elaborate, confusing process with 24-hour processing time. But rest-assured it’s possible and adds zero extra cost to your GSuite account!

To clarify, here’s what we are trying to achieve:

  1. We have an email address that looks like, [email protected]
  2. We want to send and receive from [email protected] from the same Gmail inbox. e.g. We log into the [email protected] Gmail inbox, and we can send and receive from both [email protected] and [email protected]

Sound good? Let’s go!

First, Add the Domain Alias in GSuite Admin

The first thing you have to do in order to send email from a different domain is to add a “domain alias” in your GSuite account.

From Google:

  1. Sign in to your Google Admin console.Sign in using an administrator account, not your current account [email protected]
  2. From the Admin console Home page, go to Domainsand thenManage domains.
  3. Add the domain to your account. The Admin console includes either of these steps (both work the same way):Add domain option
    • Click Add a domain or a domain alias.
    • Then click Add a domain alias of primary-domain-name or Add another domain (not available with the legacy free edition of G Suite).ORChoose domain setting
    • Click Add a domain or Add a domain alias.(Note: To add a domain alias to secondary domain, use the Domains Aliases API.)
  4. Enter the name of the domain or subdomain. You must own the domain name, and it can’t be used with any other Google Account. If the domain is already in use, you’ll get an error message. Check troubleshooting tips.
  5. Click Continue and verify domain ownership
    Follow the instructions to verify that you own the domain. If you need assistance, contact your domain host (typically where you purchased your domain) or G Suite Support.
  6. Click Verify and continue to setup email delivery.
  7. Update the domain’s MX records to set up Gmail ( G Suite only) for your added domain.
  8. Click I have completed these steps.

Then…Wait 24 hours! Yes you heard that right. Trust me – just wait.

If you stop here, you’ll start receiving email from [your_username]@[secondary_domain].com, but you won’t be able to send from [your_username]@[secondary_domain].com. Next, we’ll set up your Gmail so you can send from the secondary domain’s email address.

Next, add the second domain’s email address to your Gmail account

Strangely, there’s no way to do this in 1 click from GSuite admin – you’ll need to update each email account so that it can send from the additional domain.

From Google:

  1. On your computer, open Gmail.
  2. In the top right, click Settings Settingsand then Settings.
  3. Click the Accounts and Import or Accounts tab.
  4. In the “Send mail as” section, click Add another email address.
  5. Enter your name and your alias address.
  6. Check the Treat as an alias box.
  7. Click Next Step and follow the confirmation steps.

When you send a message in Gmail, click From Down Arrow to select an address.

Send from alias

Put differently:

1. Log into Gmail and click the sprocket on the top-right, then click “Settings”.

2.  Inside of Gmail Settings, click “Accounts” near the top-middle.

3. Under “Accounts”, click “Add another email address”.

4. In the “Email Address” field, type your email address only replace the “” with “”.  For example, if your email address is “[email protected]”, you’d type, “[email protected]” into the “Email Address” box.

5. Click “Next Step.

6. On the “Account” view that pops up next, select the “Reply from the same address the message was sent to” radio button.

That’s it!  You can now send and reply as your .com” email address!

How to merge two folders, including all sub-folders and files, on Mac

Today I had an issue where I needed to merge two folders, each of which contained many sub- and sub-sub folders that had lots of images. After a lot of trial-and-error and some Googling, I found the best solution is to use the “ditto” command in Terminal like this: That’s it! Hat tip to AppleInsider.
