In this article we will explore how to block emails on Gmail.
When you get unwanted, unnecessary, and annoying emails in your Gmail inbox, you might want to block them. Blocking an email indicates that the sender of the email no longer sends an email to your inbox, and they will be unable to communicate with you through emails in the future. Also, you can report the senders when they violate Gmail's Program Policies.

When do you need to block an email?

  • If the sender asks you for sensitive information like – personal info, password, bank account details, transaction details, OTP, and job or career-related data, you should immediately block them. So, be aware of these spammers.
  • You may get poorly written emails in your Gmail inbox. Most of the time, these emails include several miss-spelled words, grammatical errors, and unprofessional writing approaches. Undoubtedly, these emails come from scammers.
  • Sometimes, you may receive an email that contains a link from an unknown sender frequently. You should block these senders. Cybercriminals attach lengthy links within the emails to eject malware in the users' system. Thus, you must not open their messages.
  • You have to block and report the sender's harassment or threatening emails like - asking for money, property, etc.
  • Spammers try to gain trust by creating proper well-structured emails like reputed companies. They can even create perfect copies of emails from famous MNCs. These are spoof emails. You should pay attention to the sender's email address and block them. Also, you should report this sender for impersonating an organization or individual.
  • Your account may be compromised for mail bombing. In this case, the hackers send tons of unwanted promotional, subscription offers, newsletters, or other messages. As a result, you don't find essential emails in your inbox. For this reason, Gmail informs you about the mail bomb. Then you should either block their addresses or mark the emails as spam.

You should avoid empty emails. Scammers often send empty emails for phishing, block the messages and report them as spam.

Some common issues include solutions for blocking emails on Gmail

  1. The sender change or hides their real email address

After blocking an email address, you may receive the same messages from different addresses. It’s possibly the sender changing their mailing address or trying to spoof by sending emails from multiple addresses.

Solutions: You can set advanced security like –

  • You should turn on spoofing and authentication protection. This will protect you from domain spoofing, spoofing with any person’s name, and unauthenticated emails.
  • Enable attachment protection to become safe from attachments from untrusted senders.
  • Again, you can set suspicious email links, external images, and link protections.
  1. Your junk, spam, or email filtering becomes turned off

If you turn off your spam email filtering, you may receive emails from blocked email addresses.


  • Use the email filtering features for your received messages. You should go to Settings > See all Settings > Filters and Blocked Addresses.
  • Use Report Spam and Move to > Junk.
  • Make sure that anyone else is not using your Gmail account.
  1. The sender is in your Email allow list

If the blocked sender remains in your email allow list you will still receive their emails. The allow list permits according to the IP addresses of the senders. Thus, it will never impact their email address and they can send you emails even if you blocked them.

Solutions: You can save the sender within your email denylist through the following actions -

  • Create or select an address list for the blocked senders – especially for the spam, phishing, and malware emails.
  • Add rejection notice for the blocked senders. (optional)
  • Furthermore, you can use filters and reporting for unwanted messages.

Note: You need a Google Admin account to handle email allowlists and denylists.

  1. The companies or businesses use third-party services to send emails

Large companies may prefer third-party services to provide their business emails. These third-party services use multiple email addresses to send emails to the users. Thus blocking one email address can’t stop the other addresses from further communication. Also, not every time Gmail filters them and sends them to the spam filter.


  • Make aware the third-party email provider of the abuse and tell them to follow the Spam and abuse policy in Gmail.
  • They should check their SPF record to authorize all the email senders for their domain.
  • Ask them to offer an email address for reporting abuse.
  • They should remove the clients who send spam messages.
  1. The server taking time to change the settings

Sometimes your server takes time to sync your settings for blocking a sender.


  • In this case, you have to wait for 24 hours to see the changes.
  • Again, check your Wi-Fi connection. The slow connection may cause a delay in syncing.
  • Otherwise, you have to contact your admin.
