Update Email Account in Gmail

In this tutorial, I’m going to walk you through the steps of adding your business e-mail address to a Gmail account, so you can send and receive your messages inside Gmail. 

What you'll need to begin:

• Be logged into both your Gmail.com.
• Your Business Email account password. 

Let's begin... 

Click on the Settings cog (highlighted) and the See all settings option from the dropdown.

From here, click on the Accounts and Import link. 

In the Check email from other accounts section, click the edit info link next to the account you wish to update. 

Add the following options on the 'Add an email account' page:-
Username: *Your full email address* 
Password: *Your email account password* 
POP Server: pop.stackmail.com 
Port: 995
Always use a secure connection (SSL) when retrieving mail: Tick option.

All other settings are at your own discretion. When you’ve done that, click the Save Changes button.

In the Send mail as section, click the edit info link next to the account you wish to update. 

Enter the name of the account as you’d wish for it to appear in any recipients’ inbox. Ensure the Treat as an alias checkbox is un-ticked. Then click the Next Step button.

Add the following options on the 'Add another email address that your own' page:-
SMTP Server: smtp.stackmail.com
Username: *Your full email address* 
Password: *Your email account password*
Port: 587
Security method: Secured connection using TLS (recommended)

When you've done that, click the Save Changes button.

You’ll then be returned to the Settings page, where you can navigate back to the Inbox.
