How to Fix Auto Complete Feature Not Working on Gmail

Is the auto complete feature not working on your Gmail account?

Google has been dedicated to improving user experience on its platforms such as Gmail, Docs, and YouTube. Through the years, Gmail received many changes geared towards ease of use. 

One of the most helpful features of Gmail is the auto complete feature.

When you’re composing a message, Gmail automatically makes suggestions about your recipient’s address, which can be helpful if your work involves sending a lot of emails to clients and partners. 

However, auto complete isn’t perfect and could sometimes suggest wrong addresses. There are also instances when the feature is not working at all on your Gmail account.

Based on what we know, this issue on Gmail is often caused by server-related issues. On the other hand, faulty browsers, third-party extensions, or corrupted data could also be the reason behind this problem. 

To help you out, we’ve decided to make a guide for fixing the auto complete feature if it’s not working on Gmail. 

Let’s get started!

1. Check the Servers. 

When a certain feature is not working on Gmail, the first thing you should do is check the platform’s servers. Since Gmail is an online service, it relies mainly on the servers to function correctly. 

To check Gmail’s servers, you can visit Google’s dedicated status page, where you can view the current status of their services.

After clearing your data, re-login to your Gmail account to check if the auto complete feature works. 

6. Check Your Recipient’s Address. 

The auto complete feature on Gmail only works for email addresses that you’ve already sent an email to. Gmail automatically adds these addresses to your data to appear on the suggestion when you write another email. 

If the auto complete feature is not working, you may be sending an email to a new address, or you’re typing an incorrect address. 

Check your recipient’s address first before composing an email on your account. 

7. Check Your Network Connection. 

A slow internet connection could also be the reason auto complete is not working. To confirm this, run a test on your network using to measure its current upload and download bandwidth.

If the result indicates that your network is the problem, reboot your modem to re-establish the connection with your service provider. Unplug your router’s power cable from the outlet and wait for 5 to 10 seconds before reconnecting it. 

Restart Router

Perform another test afterward to check if the restart worked. If not, contact your ISP and ask them to fix their service. 

8. Contact Google Support.
