Note: Starting in January 2026, Gmail will no longer support receiving emails from external email accounts in the Gmail web version. You can still use Gmail to send emails from your domain address, and any emails that were previously imported into Gmail will remain available.

To receive incoming emails in Gmail on the web, you must set up email forwarding from your email account to your Gmail address.

In the Gmail app on Android, iPhone, and iPad, you can still add your email account using IMAP to send and receive emails.

Step 1 - Log in to Gmail and go to Settings

1. Log in to your Gmail account.
2. Click the gear icon in the top right corner.
3. Select See all settings from the drop-down menu.

Step 2 - Add the email address

1. Click Accounts and Import in the menu at the top.
2. Click Add another email address in the "Send mail as:" section.

Step 3 - Enter your email address

1. Enter the sender name you want to be visible to your recipients. 
2. Type in the email address you want to send from in Gmail.
3. Click Next Step.

Tip: If your Gmail address is your primary address, and your other email address is only for receiving, you might want to check the box for "Treat as an alias".

Step 4 - Enter the SMTP server settings

Please use the following settings for the outgoing email:

• SMTP Server: send.one.com
• Username: your email address
• Password: the password you use to log in to Webmail
• Port: 465
• Secured connection: SSL

Click Add Account to continue.

Step 5 - Open the Gmail Confirmation email

Gmail will now send you an email with a confirmation code.

1. Log in to Webmail.
2. Open the email "Gmail Confirmation - Send Mail as..."
3. Check the confirmation email from Gmail and click the link to add your email address.

Step 6 - Click the link in the Confirmation Mail

Double-check that the email address you’re adding is correct, then click Confirm.

Step 7 - Return to your Gmail account

After clicking confirm you should see a success message with "Confirmation Success". Click the link in the window to return to your Gmail account.

Step 8 - Verify your settings

Check your settings to make sure it's set up according to your preferences.

Step 9 - Done!

Your account is set up. You can now send emails from your external email account through Gmail.
