I can't send emails
This step-by-step guide will help you solve issues with sending email. Before you start, open Yandex Mail in a new tab to follow the recommendations.

Why this might happen and how to fix it:
The browser doesn't display the page correctly
-
To reduce traffic consumption, the browser saves copies of visited pages in the cache. When you view these pages again, the browser may load them from the memory. For example, if the browser loads the incoming mail page from the cache, it shows an outdated number of new messages.
Try refreshing to force a fresh download of the page. If the problem persists, clear the browser cache and delete all cookies.
Extensions block Yandex Mail
-
Mail may work incorrectly due to the browser add-ons and extensions. To check if this is the reason, temporarily disable them. If Yandex Mail works incorrectly because of an ad blocking or antivirus extension, add Yandex Mail as an exception to the extension.
If you receive an error message "Message cannot be sent because it looks like spam" ("Spam limit exceeded" or "Message rejected under suspicion") or a prompt to enter captcha numbers, this may be caused by the following:
Messages that are similar or use a template are sent out
Messages that are identical, based on a template, or contain commercial or advertising proposals are being sent from your mailbox. Yandex Mail doesn't allow you to send these types of emails. 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. To find them, use Yandex search.
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 messages can be sent with your involvement, as well as without your knowledge.
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.
Yandex Mail limits
|
Number of recipients |
Limit |
|
A 24-hour total (in messages from a single email address) |
3000 * |
|
A 24-hour total (in emails from all the addresses on the same domain) |
5000 * |
|
In a single message sent from the site |
50 |
|
In a single message sent from an email client or over SMTP |
35 |
* Only external recipients are considered. Owners of mailboxes in this domain are not considered.
Alert
Limits can be lowered if Anti-Spam notices the mass emailing of similar messages, templates, spam, advertising, or commercial offers.
Emails are sent to non-existent addresses.
A large number of messages were sent to nonexistent addresses from your mailbox. If an email is sent to a non-existent address, you receive an automatic non-delivery report .
If this occurred, sending emails from your mailbox will be blocked. Only sending emails is blocked. You will be able to log in to Yandex Mail and receive emails. The blocking is lifted automatically after 24 hours if you don't try to send an email during this time — otherwise the blocking 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:
- Please check your computer for viruses with free anti-virus programs such as CureIt! from Dr. Web or Virus Removal Tool from “Kaspersky Lab”. Then change your password.
- Enter your valid personal details in Yandex ID and link your phone number to your account.
- Make sure the your recipients addresses are entered correctly and remain active.
- Make sure that recipients of your emails have voluntarily agreed to receive them.
If you receive a message that says An error occurred. This message cannot be sent or saved, as the maximum message size has been exceeded. The message is saved in drafts, this means that the text of the message contains too many characters and images. This is usually due to quoting old messages in a long correspondence. Try shortening the message or create a new one.
Check if the email is in your Sent folder. If the email is not there, an error might have occurred while sending the email – try sending it again.
Sending the email again didn't help
If you have sent a message from your Yandex mailbox but it has been rejected by the recipient's mail server, you will get an automatic report from “Mailer-Daemon” with reasons for non-delivery and the name of the server which rejected passing the message to its destination.

|
The email was sent to a non-existing address. Make sure the recipient's address does not include extra punctuation marks, spaces, or quotation marks. Confirm the recipient's email address and resend the message. |
|
|
The email seems to be spam. If only spam is coming from your mailbox, the Yandex mail server will block receipt of messages from it for 24 hours. Note If you are sending legitimate messages to your website users or subscribers, please read Yandex requirements for honest mailing lists. |
|
|
Your recipient's account has been blocked due to User Agreement violations. Try contacting the recipient by another method and report the problem. If you are the owner of the address to which the message has been sent, you can unblock it yourself. Fill in accurate information about yourself on the Personal information page and you will be unblocked after a while. If you provided accurate information but weren't unblocked, please contact our support team via the feedback form at the bottom of the page. |

The recipient's mailbox is full. This usually happens because the recipient rarely uses their mailbox 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. |
|
|
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. |
|
|
The recipient's email server is not responding. The recipient's email server took too long to respond and the Yandex email server disconnected and aborted the email delivery. Try contacting the recipient by another method and report the problem. |
|
|
The Yandex mail server is overloaded because of numerous requests from other servers. This increases the load on the server and slows it down. Try contacting the recipient by another method and report the problem. |

I haven't received a non-delivery report
