How to send emails from a different address

To send emails from a different email address or alias using an email, we add other non-Gmail services like Yahoo, Outlook, etc…

We can add upto 99 different email addresses

Step 1: Add an address you own

1. On your computer, open Gmail.
2. In the top right, click Settings   >>  See all settings.
3. Click the Accounts >> "Send mail as" section, 

   

   4.   Click Add another email address.

  

   5.   Enter your name and the address to which you want to send from.

   

   6.   Click Next Step >>  Send verification.

   7.   For school or work accounts, enter the SMTP server (for example, smtp.gmail.com or smtp.yourschool.edu) and the username and password on that account.

    

                    Check with your other mail service for their recommended port number, authentication type, or outgoing mail server. Make sure your third-party provider supports SSL or TLS with a valid certificate.

Here are some common combinations:

1. SSL with port 465
2. TLS with port 25 or 587

   8.   Click Add Account.

Step 2: Confirm the address

1. Sign in to the account you added.
2. Open the confirmation message you got from Gmail.
3. Click the link.

Step 3: Change the "From" address

1. In the message, click the "From" line.
   (If you don't see this, click the space next to the recipient's email.)
2. Select the address to send from.

Remove an email address or alias:

 

If you don’t want to send emails from an alias or if the alias is invalid, you can remove the email or alias. If you send an email from an invalid alias, you get a bounce email. 

1. On your computer, open Gmail.
2. At the top right, click Settings >>  See all settings.
3. Click the Accounts tab.
4. In the "Send mail as" section, next to the email address you want to remove, click Delete.

Tip: If you get a bounce email from a valid email address and need to reverify it, you must delete the "Send mail as" email address and then add it again.
