How to Stop Unwanted Emails in Gmail

Written by Sandy Writtenhouse

Eliminating spam emails in Gmail takes more than one tool or action. It learns from your behavior — and if you’re not using the right signals, junk emails keep slipping through. This guide shows exactly how to stop spam emails in Gmail on both desktop and mobile.

Fast Actions

To stop unwanted emails in Gmail, use these steps:

  1. Report spam – this trains Gmail to block similar emails automatically
  2. Block senders – prevents future emails from these senders
  3. Unsubscribe – for newsletters from legitimate companies
  4. Create filters – automatically delete unwanted emails
  5. Avoid interacting with spam – don’t click links or reply

👉 For best results, combine these methods instead of relying on just one.

How Gmail Actually Stops Spam (And Why It Sometimes Fails)

Gmail already filters a huge amount of spam automatically, but it depends on user input to improve.

Here’s how it works:

These are the reasons why you may still see new unwanted emails even after blocking or deleting some of them.

👉 This is why the most effective starting point is always: consistently reporting spam, not just deleting it.

Report Spam

Reporting spam is one of the best ways to stop receiving junk mail on Gmail. This lets Gmail know that it’s an unsolicited message and gives you an option to block future emails at the same time.

How to report spam on Gmail (web)

  1. Select or open the email.
  2. Click the Report spam button (exclamation mark).
  3. Pick Yes, block to also stop further emails from the sender or No to allow them.

How to report spam on Gmail (mobile)

  1. Select the email.
  2. Tap the three dots at the top.
  3. Select Report spam.
  4. Choose whether to block the sender as well.

Do this consistently — it’s the fastest way to improve your inbox over time.

Block Emails

While you can block junk emails when reporting them, you might want to block a sender in Gmail directly — for example, if someone is repeatedly contacting you.

How to block unwanted emails on Gmail (web)

  1. Open the message.
  2. Click the More icon (three dots).
  3. Select Block "Sender".
  4. Confirm with Block.

How to block unwanted emails on Gmail (mobile)

  1. Open the email.
  2. Tap the three dots at the top of the message.
  3. Select Block [Sender].

⚠️ Important: If you suspect an email is spam, it’s best not to open it. Since the Gmail mobile app doesn’t allow blocking emails without opening them, we recommend using Clean Email on mobile instead for safe blocking options.

Unsubscribe From Emails

If the emails you receive are from legitimate companies, unsubscribing is often the best option.

How to stop unwanted emails in Gmail by unsubscribing

  1. Open the email.
  2. Click or tap Unsubscribe near the sender’s name.
  3. Confirm with Unsubscribe or complete the process on the sender’s site with Go to website.

⚠️ Important: Only unsubscribe from trusted senders. For unknown or suspicious emails, it’s safer to mark them as spam instead of interacting with them.

💡 When you unsubscribe in Gmail, you can only do so for one email at a time. With Clean Email, you can unsubscribe from multiple messages at once which can save you a ton of time! You can try this feature on the web and mobile, as it works the same on both platforms.

Filter Emails

One more way to stop spam emails in Gmail is by using filters. This is an automation that catches and applies actions to messages as they arrive, making it a convenient way to go.

How to stop junk emails in Gmail with filters

  1. Open or select an email.
  2. Click the three dots in the top toolbar.
  3. Choose Filter messages like this.
  4. Set conditions and click Create filter.
  5. Choose an action (e.g., Delete, Skip inbox) and click Create filter.
