Fighting spam

Spam is unsolicited email that may be delivered your address. It may contain advertising, “chain letters”, computer viruses, or even be a phishing attempt. Address databases are created by spammers using dedicated programs that pick addresses using a special dictionary or just collecting addresses posted publicly.

Unsolicited mail should be differentiated from honest mail. Proper mailing lists usually imply explicit consent. You can also unsubscribe to stop receiving such emails.

Yandex.Mail uses the “Anti-Spam” service, which learns from user-submitted spam complaints, to recognize spam. It puts suspicious email with spam features in the Spam folder.

Note. All messages in the Spam folder will be automatically deleted in 10 days. Note that you will not be able to recover deleted email.

Yandex.Mail filters not only incoming but also outgoing mail. Each email is checked for viruses. Messages in which a virus is detected will be rejected by the mail server and the sender will receive a report.

Spam issues

This step-by-step guide will help you solve issues related to spam. Before you start, open Yandex.Mail in a new tab to follow the recommendations.

Select a problem:

If you think you have received a spam message in your Inbox, select the message and click Spam! and it will be moved to Spam and the required information will be sent to Anti-Spam.

After submitting several complaints about the same kind of message, Anti-Spam starts putting all similar email into Spam. Mark all the email you think is spam by clicking It's spam! until all such messages are sent to the Spam folder instead of your Inbox.

Tip. Send unsolicited emails to Spam one by one. All email from one sender that gets moved to the Spam folder at one time is considered as one complaint.

If a message gets into Spam by mistake, click Not spam! and new messages from the mailing list will go to the Inbox.

Anti-Spam takes into account both general and “personal” filtration rules which apply to specific mailboxes. Any messages that you believe to be unsolicited but another mailbox user finds useful will be filtered into Spam in your mailbox and into the Inbox of the other user's mailbox.

If you receive a lot of spam in the Spam folder, it means that Anti-Spam works. If the email is really suspicious, leave it in this folder — it will automatically be deleted in 10 days. If the folder contains email you need, restore it.

If you want to automatically erase all new messages that are sent to the Spam folder, configure your mail filters:

  1. In the Apply list, choose to all messages including spam.
  2. Specify the following rule for the If section: From field contains <domain_name>”.
  3. In the Perform action section, choose Remove.
  4. Click Create rule.

If you are informed that spam was sent from your address or if you receive spam emails from your own email address, the reasons for this might be:

Malware infection of your computer
If the computer was infected with a virus, your Yandex.Mail account might have been hacked. Check your computer for viruses using free antivirus programs, like CureIt! by Dr.Web or Kaspersky Virus Removal Tool. Then change your password.
Spoofing (forged mail headers)

Check if the email is located in the Sent folder. If the email is not there, it means that someone is sending spam with your email address specified as the reply address.

You might also get a message from the “Mailer-Daemon” service with an automatic email non-delivery report for an address that you didn't send anything to.

This usually happens because of spoofing. Spoofing is a type of internet scam, with the aim to distribute information in the form of unsolicited advertising (spam). Spammers enter fake addresses in the email properties (such as From or Reply to). They do not actually have access to your mailbox, but they use your address instead of the real address of the sender.

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.

Yandex.Mail doesn't distinguish between addresses with uppercase and lowercase letters. 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 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.

If you receive the error message "Message cannot be sent because it looks like spam" (“Spam limit exceeded” or “Message rejected under suspicion of SPAM”) or a prompt to enter a captcha code, this may be caused by the following:

Messages that are similar or use a template are sent out

Messages that are similar, use a template, or contain commercial or advertizing proposals are sent from your mailbox. Yandex.Mail doesn't allow you to send these types of email. Our service is intended for actual communication between people.

Tip. If you want to send out mass emails to your partners or clients, please use our special mailing services.
The daily limit on how many emails you can send was reached

Your mailbox sends out a large number of messages every day, which is regarded as spam by our security system. The emails can be sent both with your involvement and without your knowing about it.

In order to avoid this, Yandex.Mail has set restrictions on the number of emails you can send each day. These restrictions cannot be changed or avoided.

You can send up to 500 emails from one mailbox in a 24-hour period. If the email has several recipients, then each individual email sent counts separately towards your total.

Additional limitations are set on the number of recipients:

Number of recipients Restriction
Total for all email in a 24-hour period 500
In one email sent from the site 50
In one email sent from a mail client or over SMTP 35
Attention. Limits can be lowered if Anti-Spam notices the mass emailing of similar messages, templates, spam, advertising, or commercial offers.
Your account was marked as suspicious

Our security system flagged your account as suspicious. Usually this happens if you didn't link a phone number to your mailbox or a fake name was entered in your Yandex.Passport.

messages are sent to non-existent addresses.

A large number of messages were sent to nonexistent addresses from your mailbox. If email is sent to an address that doesn't exist, you receive an automatic non-delivery report .

We received a complaint about a mailing sent from your email address

We received several complaints from users about spam sent from your email address.

If this occurred, sending email from your mailbox will be blocked. Only sending emails is blocked. You will be able to log in to Mail and receive emails. If you don't try to send email during this time, the block is automatically lifted after 24 hours — otherwise the block is extended for another 24 hours.

While you are waiting for the block to be removed, follow the recommendations below to avoid similar issues in the future:

  1. Check your computer for viruses using free antivirus programs, like CureIt! by Dr.Web or Kaspersky Virus Removal Tool. Then change your password.
  2. Enter your valid personal information in Yandex.Passport and link your phone number to your account.
    Note. If you use Yandex.Mail for a domain, enter the exact data for all the domain mailboxes.
  3. Make sure the your recipients addresses are entered correctly and remain active.
  4. Make sure that recipients of your emails have voluntarily agreed to receive them.

If you receive “Message rejected under suspicion of SPAM”, it means that Yandex.Mail determined that the contents of your email is spam. To resolve the problem, open the Yandex.Mail web interface and send a test email. This shows the system that messages are not being sent by a robot.

Check your computer for viruses using free antivirus programs, like CureIt! by Dr.Web or Kaspersky Virus Removal Tool.

If a non-spam message arrives in the Spam folder by mistake, select it and click Not spam!. This email is then moved to the Inbox folder. After a while, all emails from this address will start arriving in the Inbox folder again.

Make sure your mail filters are not set up to move such messages to Spam. If any filter is doing this, disable it.

The Not spam! button doesn't work

Emails may end up in Spam if you use certain mail clients to manage your Yandex.Mail (such as Microsoft Outlook, The Bat!, or Thunderbird for desktop or Mail.Ru, Gmail, or Mailbox for smartphone or tablet). Some mail clients have built-in anti-spam filters that may send emails to the Spam folder.

If the Not spam! button does not work on the Yandex.Mail site, click it in your mail client or in the app (it may have a different name in different mail clients). Also disable the Spam check in the settings of your mail client so that emails aren't sent there automatically.

If the program has no spam filter, then change the password to your Yandex mailbox. Changing your password may help if you set up the program earlier and don't currently use it, but the program is still running and continues to send emails to Spam.

If you have signed up for newsletters from a site or service and no longer wish to receive email from them, you can unsubscribe right from your mailbox. To do this, open any email from this sender and click Unsubscribe:

After you click the button, the selected message will be moved to Trash. Messages from this sender will no longer be delivered to your mailbox.

Attention. If the unsubscribe procedure was unsuccessful (for example, a wrong unsubscribe link was provided in the message or the request was processed incorrectly by the website or service), messages from the sender will continue arriving in your mailbox but they will be filtered as Spam.

If the email doesn't have an Unsubscribe button, add the sender's address to the blacklist or configure a mail filter that deletes email from this sender.

If you receive emails from companies, services, or social networks that urge you to follow the link inside, don't click it. Those are phishing messages. Phishing refers to a variety of online scams that are designed to get your confidential information.

Learn more about fraudulent email (phishing)

Scammers send fake email on behalf of companies and services that you use: social networks, postal services, government agencies, or payment systems. The email messages are written and formatted in a convincing way to avoid suspicion. The sender's name and address also looks similar to the real ones. Hackers disguise phishing email in hopes you won't notice the difference.

The messages usually try to persuade you to click the link inside and enter some personal data (your account passwords, credit card number or PIN, etc.) for some supposedly important reason. The link leads you to a fake website. These sites usually mimic the appearance of their real counterparts, so it's quite easy to be misled into entering personal data on such a website. Scammers get the information they need and use it to send spam to other users, get access to your social network account, or even steal money from your bank account.

Attention. Yandex will never send email asking you to follow a link and enter personal data.
How to tell a phishing email apart from a real one

Make sure to check the addresses of links. To learn where a link leads to, hover over it without clicking. You will see the address in the bottom left corner of the window.

A Yandex address follows the format https://yandex.com/section or https://service.yandex.com/section. yandex.com must always be followed by the / symbol, not a dot. If the address you see is different, contains typos, or has a random string of symbols, don't click it.

If you did click a link, check the site address in the browser address bar.

How to prevent becoming a victim of fraud
  • Carefully check all incoming email messages and link addresses.
  • Never pay for purchases or bills you don't remember. Never send text messages to suspicious phone numbers and never share your Yandex password.

Yandex.Mail marks all phishing emails with a special warning:

If you discover a phishing or otherwise suspicious email that is not marked with a warning, please let us know using the feedback form and include its properties.

If you fall victim to fraud
  • Contact the police if funds have been unlawfully debited from your account.
  • If you followed a phishing link, check your computer for viruses using free antivirus programs, like CureIt! by Dr.Web or Kaspersky Virus Removal Tool.
  • If you shared your password on a phishing website, make sure to change your Yandex.Passport password, link your phone number to your account, and change your security question and answer. First you should check your computer for viruses, though. If you lost access to your account, follow the instructions to restore access.
If a phishing email is not marked with a warning

If you discover a phishing or otherwise suspicious email that is not marked with a warning, please let us know using the feedback form and describe it.
