You ever open a new email, start typing a name, and suddenly some random person you emailed once back in 2014 pops up as the first suggestion? It’s annoying. Seriously. Our digital lives are cluttered with "Other Contacts" that Google collects like digital dust bunnies. If you're trying to remove contacts from Gmail, you've probably realized that it isn't always as simple as hitting a delete key on a single email.
Google is smart. Maybe too smart.

The system automatically saves every single person you interact with. This happens because of a default setting in your Google Account that adds anyone you reply to into a specific folder. It’s meant to be helpful, but eventually, your contact list becomes a graveyard of former coworkers, one-time Craigslist sellers, and that one guy from a networking event whose name you don't even remember.
Why your Gmail is a contact hoarder
Let's talk about why this happens. Google uses a centralized system. Your contacts aren't technically "in" Gmail; they live in Google Contacts. Because everything is synced, your phone, your tablet, and your browser all pull from the same messy pile. If you delete someone from your phone but don't fix the source, they'll often just... reappear. Like a digital ghost.
Actually, there are two types of contacts you're dealing with. There are the ones you manually added—the ones you actually want—and then there’s the "Other Contacts" list. That second category is where the chaos lives.
How to actually remove contacts from Gmail
If you want to clean house, you need to head to contacts.google.com. Don't try to do the heavy lifting inside the Gmail app on your phone; the interface is too limited for a mass purge. Once you're there, you'll see your main list.
Cleaning it up is fairly straightforward.
You can hover over a contact's icon or name. A checkbox appears. Click it. Now, you can go down the list and click every person who no longer needs a spot in your digital life. Once you’ve selected your targets, look at the top right. Click the three dots (the "more" menu) and hit delete. Gone.
But wait. There’s a catch.
If you only delete from the "Contacts" tab, you're missing half the problem. Look at the left-hand sidebar. See that section labeled Other Contacts? That is the secret lair of every random email address you've ever replied to. You need to go in there and do the same thing. Select all, then delete. If you don't clear this out, those names will keep popping up in your "To" field when you compose a new message.
Dealing with the sync issue
Mobile users have it harder. If you're on an iPhone or Android, your device might be syncing contacts from multiple places—Outlook, iCloud, and Gmail. If you delete a contact in Gmail but it stays in iCloud, your phone might try to "help" by syncing it back to Google.

It's a loop. A frustrating, never-ending loop.
To break it, you have to ensure your sync settings are tightened up. On Android, this is in your account settings under "Google" and then "Account Services." On an iPhone, you'll find it under "Settings," then "Contacts," then "Accounts." Honestly, it’s often easier to just turn off contact syncing for accounts you don't use frequently.
Stopping the madness before it starts
You can actually tell Google to stop being so clingy. If you hate that Gmail adds everyone automatically, you can toggle this off.
- Open Gmail on your desktop.
- Click the gear icon (Settings) and then "See all settings."
- Stay on the "General" tab.
- Scroll down until you see Create contacts for auto-complete.
- Switch it to "I'll add contacts myself."
This is a game changer. It means only the people you want in your address book will be there. No more randoms. No more clutter.
The "Frequently Contacted" headache
Google has this "Frequently Contacted" algorithm. It’s not a folder you can just empty. It’s a dynamic list based on your behavior. Sometimes, even after you remove contacts from Gmail, they still show up there because the system remembers you used to talk to them a lot.
The fix? Patience. Or, more accurately, more deleting. If you delete them from both "Contacts" and "Other Contacts," the algorithm eventually gets the hint. It usually takes about 24 to 48 hours for the cache to clear across all your devices.
What about Google Workspace?
If you're using a work email, things get slightly more complicated. Your organization might have a Global Address List (GAL). You cannot delete people from the GAL. Those are your coworkers, and your IT admin controls that list. If "Steve from Accounting" keeps appearing and you've already deleted him from your personal contacts, it's because he's in the company directory. You're stuck with Steve.
Common misconceptions about deleting contacts
Some people think that deleting a contact also deletes your email history with them. It doesn't.
That’s a big one.
You can wipe someone from your address book entirely, but every email you've ever sent or received from them will stay in your archives unless you go and delete those specifically. Deleting a contact is just about the "address book" side of things. It's about what happens when you start typing in the "To" box.
Another weird quirk: if you have a contact with multiple email addresses, and you only delete one of them, Google might merge the remaining one with a "suggested" profile if that person is in your Google Plus circles (or what’s left of that ecosystem) or has a public profile.
Troubleshooting the "Will Not Delete" bug
Sometimes you click delete, and the contact just stays there. Or it vanishes and comes back five minutes later. Usually, this is a conflict with a third-party app. If you use a CRM like Salesforce or an app like Hubspot, those programs often have "write" access to your Google Contacts.
They are essentially fighting you. You delete; they restore.
To fix this, you have to go into your Google Account security settings and see which apps have access to your contacts. If you see something suspicious or an app you no longer use, revoke its access. That usually stops the "zombie contact" phenomenon.
Mass deletion for the brave
If your contact list is in the thousands and you just want a fresh start, there is a "nuclear" option. In Google Contacts, you can select one contact, then click the "Selection Actions" menu at the top left to "Select All."

Be careful.
Once you hit delete on 3,000 contacts, there is a brief window to "Undo" at the bottom of the screen. If you miss that, you have to rely on the "Trash" folder. Google Contacts now has a trash bin that holds deleted items for 30 days. It's a safety net for those "oh no" moments.
Actionable steps for a clean Gmail
Start by visiting the Google Contacts website rather than using an app. It gives you the bird's-eye view you need.
- Audit the "Other Contacts" folder first. This is where 90% of your junk lives. Select all and delete if you don't recognize them.
- Toggle off the "Auto-add" feature in your Gmail settings so you don't have to do this again in six months.
- Check your "Trash" folder if you accidentally delete your mom or your boss. You have 30 days to pull them back out.
- Merge duplicates. Google has a "Merge & Fix" tool on the left sidebar. Use it. It combines scattered info for the same person into one clean entry.
- Review third-party permissions. If contacts keep reappearing, kill the link between Gmail and your old CRM or old phone syncing software.
Cleaning up your digital footprint feels good. It makes you more productive and prevents those awkward "wrong person" email accidents. Take ten minutes, dive into the settings, and reclaim your compose box.
