With the problem when emails do not arrive, many users face it. This can be due to various reasons: from a simple mistake in the address to technical failures of the email service. Such a situation causes concern, especially if you are waiting for an important email.

In this article, we will analyze the main reasons why emails do not arrive and offer solutions.

Main reasons why emails do not arrive

When emails do not arrive, it can be caused by several reasons. Let's deal with the most common ones and explain how to handle them.

Emails go to spam

One of the most common reasons — emails automatically end up in the "Spam" folder. This happens due to email service filters that may mistakenly consider an important email to be advertising or a suspicious message.

What to do?

• Open the "Spam" folder in your email service (Gmail, Yandex.Mail, etc.).
• If you find the needed email there, highlight it and click "Not spam" or "To Inbox."

Errors in the email address

Another common reason — typos or errors in the email address. Even one incorrect letter or symbol can result in the email not reaching you.

What to do?

• Check whether you correctly indicated your email during registration on websites or when subscribing to newsletters.
• If you expect an email from someone, ask the sender to ensure they entered your address correctly.
• Pay attention to the email domain (e.g., @gmail.com, @yandex.ru), as an error in this part of the address can also be the cause of the problem.

Full mailbox

If your mailbox is full, new emails may not arrive. At that time, you might not even receive notifications that there is no room left.

Email services provide a limited storage volume for each user. When the limit is reached, new emails stop coming.

What to do?

• Open your email and delete unnecessary emails, especially those that take up much space (e.g., with attachments).
• If you don’t want to delete emails, you can archive them or move them to cloud storage.
• Check if it's possible to increase the mailbox volume. Some services offer paid plans with additional space.

Problems on the sender's side

Sometimes, the reason may not be on your side, but with the sender. For example, their mailbox is blocked, or they made a mistake when sending the email.

What to do?

• Contact the sender and ask if the email was sent.
• Ask them to check if their mailbox is blocked.
• If the sender uses corporate mail, the problem may be related to their mail server settings.

These reasons are the most common, but not the only ones. If none of the methods helped, consider other options such as technical failures of the mail service or issues with the internet connection.

How to avoid problems with email

To avoid situations where emails do not arrive, it's important to follow a few simple rules. These recommendations will help you minimize the risks and always stay in touch.

Regularly check the "Spam" folder

Email services actively combat unwanted email, but sometimes their filters make mistakes. Important emails might accidentally end up in the "Spam" folder.

What to do?

• Every few days, open the "Spam" folder and check if there are any emails that should have gone to "Inbox."
• If you find the needed email, mark it as "Not spam" and add the sender's address to contacts.

Monitor the mailbox volume

A full mailbox is one of the common reasons why new emails do not arrive. To avoid this problem, it's important to monitor the number of emails and attachments.

What to do?

• Regularly delete unnecessary emails, especially those that take up much space (e.g., with large attachments).
• Use archiving for emails that you want to save but do not need in the near future.
• If your email service allows, increase the storage volume by switching to a paid plan.

Use a backup email for important emails

One of the most effective ways to avoid problems is to divide mailboxes by purpose.

How to do it?

• For registrations and advertisements
  Create a separate email, which you will use for subscriptions, newsletters, and registrations on websites. This helps to not clutter the main inbox.
• For important emails and correspondence
  Use the main email for work, personal correspondence, and receiving important notifications.
• For file exchanges
  If you often send and receive large files, open another mailbox or use cloud services.

How to check if the email is blocked?

Access to email can be blocked by the email service. This can be due to a violation of service rules, suspicion of hacking, or spam sending. Depending on the situation, the block can be temporary or permanent.

Why mailboxes are blocked?

• Spam sending
  If your mailbox was hacked and used for mass spam sending, the email service can block it.
• Violation of service rules
  For example, using email for distributing prohibited content.
• Suspicious activity
  If the service notices unusual activity (e.g., login from different devices or countries), it might temporarily block the mailbox for your safety.
• Complaints from other users
  If complaints are received about your email (e.g., for spam or offensive emails), the service might take action.
• Long non-use
  Some email services block mailboxes that have been inactive for a long time.

How to fix the situation?

• Follow the instructions of the email service
  Usually, upon blocking, the service offers steps to restore access. For example, identity confirmation, password change, or answering a security question.
• Change the password
  If the mailbox was hacked, immediately change the password. Use a strong password and two-factor authentication.
• Contact support
  If you cannot restore access yourself, write to tech support. Prepare information proving it’s your mailbox (e.g., answer the security question or recovery data).

How to avoid blocking in the future?

• Do not use email for spamming or distributing prohibited content.
• Regularly change the password and use two-factor authentication.
• Do not share login data with third parties.
• Periodically check your email, even if you rarely use it.

Can emails not arrive due to antivirus?

Yes, antivirus programs can affect email reception. Although their main task is to protect the computer from malware, sometimes they can block quite safe emails.

Why does antivirus block emails?

• Too strict antivirus settings
  If the antivirus is set to the maximum protection level, it can block even those emails that do not pose a threat.
• Emails with attachments
  Antivirus often checks email attachments. If the file seems suspicious (e.g., due to format or size), it can block the email.
• Links in emails
  If there are links in the email, the antivirus can check them for safety. If the link seems suspicious, the email can be blocked.

How to check if the antivirus blocks emails?

1. Temporarily disable the antivirus
   Disable the antivirus for a few minutes and check if the emails are arriving. If the problem disappears, then the antivirus was the cause.
2. Check antivirus settings
   Open antivirus settings and find the section related to email (e.g., "Email antivirus" or "Email protection"). Make sure the protection level is not too high.
3. Check block logs
   Many antiviruses keep logs recording blocked emails or attachments. Find this section and check if there are any needed emails.

What to do if the antivirus blocks emails?

1. Add the email service to exceptions
   In antivirus settings, find the "Exceptions" or "Trusted programs" section and add your email application or email service site there (e.g., Gmail or Yandex.Mail).
2. Adjust the protection level
   Lower the antivirus protection level. For example, you can disable incoming email checks but leave attachment checks enabled.
3. Update the antivirus
   Make sure you have the latest antivirus version installed. Sometimes, email problems occur due to outdated software.
4. Use the web version of the email
   If the antivirus blocks emails in the email application, try accessing your email via a browser. The web version of the email service usually does not conflict with the antivirus.

If emails do not arrive due to the antivirus, this is easily fixed by changing the settings or adding the email service to exceptions. The main thing is not to completely disable the antivirus to avoid exposing your computer to risks.
