You can renew your domains in two different ways: manually or automatically.
If your domain is set to manually domain renew, you’ll receive multiple reminder emails and you’ll see a red Renew button or an alert sign in the upper right-hand corner of your account once your expiration date gets close (about 45 days prior). At that point, you’ll have two choices:
Click on the alerts in your account:
If you’re not automatically directed to your My Products page, make sure to click on the My Products tab.
Now you’ll be able to click on the red Renew button next to your expiring domain, or an alert notification in the upper right side of your account.
Follow the prompts and complete the checkout process.
Or, turn on automatic renewal:
Turn on automatic renewal in your account.
The best way to ensure that your domain remains available to you and only you is to turn on auto renew.
