So some many of us that have different email addresses for different purposes may find it uneasy sometimes to access all at the same time. There is a limit to the number of browsers you can have on your computer. Therefore, it is a must to always sign out of an email account before signing into another. 
Gmail has that feature that allows you send emails from your other addresses with one Gmail account. This means that you can use that Gmail account to send or receive emails from other addresses. First, to begin, you must add the other emails addresses to the main Gmail account you wish to use. 
In the tutorial below, you will see how to add other emails addresses to a Gmail account to send or receive emails with it.
==> Go to Settings.
==> Click on Accounts and Import.
==> Click on Add another email address.
==> Input the Sign in details of the Email account you wish to add and click on Next Step.
==> You will be required to verify the email address you want to add. Click on Send Verification.
Sign in and copy the confirmation code sent.
==> Enter the confirmation code and click on Verify.
==> Once the email address has been verified, it will appear among the list of email addresses. You can decide which you will make as default. Lastly, tick ‘Reply from the same address the message was sent to.’
When you go to Compose and wish to send a new message, there you will have the option of choosing which email addresses you want to send from by clicking on the drop-down arrow.
This process can be used to add Yahoomail, Hotmail, and even custom emails. If you follow the above steps closely, you should be able to add emails addresses to your Gmail and send or receive emails with it.
