Problems with getting and viewing emails

This step-by-step guide will help you solve issues with viewing and receiving emails. Before you start, open Yandex.Mail in a new tab to follow the recommendations.

Select a problem:

Please specify whose emails you aren't receiving.

Please check if personal data you specified in Yandex.Passport is accurate and link your phone number to your account. It may be that our security system considers your account suspicious and blocked the mailbox. This usually happens if you don't link a phone number to your mailbox or enter a fake name in Yandex.Passport. It usually takes a couple of hours to have your account unblocked.

While you're waiting to be unblocked, make sure that the sender's email address isn't blacklisted. Remove the email address from the blacklist if this is the case.

As waiting time ends, ask the sender if they wrote your address correctly. Then ask them to send you an email again.

Try looking through all of your mailbox's folders.

Make sure that your message filters don't contain a filter that deletes these types of emails. If any filter is doing this, disable it.

Select this email and click Not spam!. The email will then be moved to your Inbox. After that, open your email filters and whitelist the sender's email address. Email sent from whitelisted email addresses is never moved to the Spam folder.

Make sure your email filters are not configured to move such emails to this folder. If any filter is doing this, disable it.

You might not have received the email due to technical issues on your or the sender's servers, heavy traffic, etc. If this is the case, the sender will receive an automatic non-delivery report from “Mailer-Daemon”.

Possible reasons for non-delivery

The reason for why the email was not received will be indicated in the automatic report. How to find and interpret the error:

  1. Find the phrase Diagnostic Code. You will see the error code to the right of it.

If you have provided accurate information but weren't unblocked, please contact our support team via the feedback form at the bottom of the page.

Mailbox size exceeded

Mailbox size limit exceeded

Message infected by virus

The recipient's mailbox is full. This usually happens because the recipient does not use their mailbox often and their mailbox is full.

Try contacting the recipient by another method and report the problem. The recipient will have to log into Yandex.Mail via the web interface to be able to receive emails again.

Error: message file too big

Message size exceeds fixed limit

The attached file is too big. The Yandex email server cannot accept your attached file due to size restrictions. The maximum size of messages with attachments that can be sent to Yandex mailboxes is 30 MB.

Upload your attachment to a file storage service (such as Yandex.Disk) and include a link to it in your message.

Error: too many connections

The Yandex mail server is overloaded because of numerous requests from other servers. This increases the load on the server and slows it down.

Error: too many recipients

This message has too many recipients, i.e. more than 35 addresses in the To, Cc, and Bcc fields.

Edit the list of recipients and try again.

Delays may occur on either the sender's servers or on Yandex's servers.

To determine where the delay occurred:

  1. Open the properties of the email that was delayed.
  2. The properties contain several Received fields. Find the one at the very bottom next to the Subject and From fields.
  3. The server address and time when the email reached the server are indicated in the Received field. If you look up through the chain in the Received fields and compare times, you can find out the address of the server where the email was delayed.

    If an address of the type example.mail.domain.net has yandex before the last period (i.e. in the place of domain), it means that the email was delayed on Yandex's server. If a different value is there, it means the delay occurred on another mail service's server.

There are a few reasons why this might occur:

The browser doesn't display the page correctly

To reduce the amount of data you use, the browser saves the pages you visit in the cache. When you view these pages again, the browser may load them from the cache. For example, if your browser loads your inbox page from the cache, you will see an outdated counter value.

Try refreshing the page so that the browser has to load it from the internet. If the problem persists, clear the browser cache and delete all cookies.

Extensions block Yandex.Mail

Yandex.Mail may not work properly due to certain browser extensions or add-ons. You can temporarily disable them to determine if this is the case. If an ad blocker or an anti-malware extension are causing problems with Yandex.Mail, add the Yandex.Disk page to the extension's exceptions list.

You are using an outdated browser

An outdated browser may not support the technologies used for quickly and easily loading pages. Install the latest version of your browser.

You may get an email non-delivery report at an address that you didn't send anything from. This happens when spammers enter fake addresses in the From field and Reply-to hidden field. Your email address may have ended up in a database of fake addresses; spammers don't even need access to your account. The base is created by trial and error with the help of a special dictionary or populated by searching addresses that users publish on publicly open websites.

Users of any mail service may come across dangerous situations since not all servers that handle mail delivery meet sender identification requirements. If you receive this type of email, select it and click Spam so that Yandex can improve its spam filtration.

Check your Session history to make sure that nobody has sent messages from your mailbox other than you.

Check the address shown in the To field of these messages.

If your address contains a hyphen but you receive email for an address with a dot, or vice versa, the messages are probably yours, not someone else's.

Yandex.Mail doesn't distinguish between dots and hyphens in email addresses. These are aliases — synonymous addresses for the same mailbox. They always belong to the same recipient. For example, if you registered my-address@yandex.com, you can also send and receive emails with my.address@yandex.com. No one else can use either of these addresses.

If your address contains uppercase letters but you get email meant for the same address with lowercase letters (or vice versa), the messages are probably meant for you.

If you're receiving emails from an address you don't recognize, there could be several reasons:

Sender error when providing the address of the recipient

If you received a message from an unknown sender, the sender may have made a mistake when specifying the address of the recipient. You can inform the sender of the mistake or just ignore the email.

Someone registered on a website using your email address as a contact
Some websites allow registration without email confirmation. This means that people can enter an email address that is not theirs. Even if someone enters your address on a website, they can't use your mailbox. If you don't want to receive email from this site:
  1. Add the sender's address to the Blacklist.
  2. Contact the website administrator and inform them that your address was used on their site by mistake.

If you've received an email from someone you know but it was sent to another address, then your address is probably listed in the Bcc field. Such messages may be meant for you. Contact the sender some other way and ask them.

In some cases, this may happen if another mailbox is configured to forward messages to your address. If forwarding was set up by someone else, contact the administrator of the server hosting the mailbox that forwards your email and attach a copy of the email along with its properties.

If you've received email from someone you don't know meant for another address, then your address is probably listed in the Bcc field. Messages like this might be spam.

In some cases, this may happen if another mailbox is configured to forward messages to your address. If forwarding was set up by someone else, contact the administrator of the server hosting the mailbox that forwards your email and attach a copy of the email along with its properties.
