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 instructions.
Select a problem:
- 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 the browser loads the incoming mail page from memory, the new message counter shows an outdated 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 ad blockers or antivirus extensions are causing problems with Yandex Mail, then you can add the Yandex Mail page to the list of exceptions for that particular extension.
If you receive a message that says An error occurred. Please try again in a few minutes, this means you are trying to use Yandex Mail to send messages from an address hosted on another email service. Check that you have a fetcher configured from that mailbox to your Yandex mailbox. You cannot select an address on another mail service as an alias without a configured fetcher.
If you can't send messages from an email address hosted on another mail service even though the importer is set up correctly, that means that the security rules of that service prohibit sending messages via different mail services, including Yandex Mail.
To continue sending messages via Yandex Mail, select your Yandex address in the From field (login@yandex. com ).
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:
- Yandex Mail limits
-
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 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.
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 this type of message. Our service is intended for actual communication between people.
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.
To avoid this, Yandex Mail has set restrictions on the number of emails you can send per day. These restrictions cannot be changed or avoided.
Our security system flagged your account as suspicious. This usually happens if you don't link a secure phone number to your mailbox or enter a fake name in Yandex ID. Check this data and update it if necessary.
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 .
We received several complaints from users about spam sent from your email address.
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. 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:
- Check your computer for viruses using free antivirus programs, like CureIt! by Dr.Web or Kaspersky Virus Removal Tool. 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 the “Message rejected under suspicion of SPAM”error, this means that Yandex Mail recognized the contents of your email as spam. To resolve the problem, go to Yandex Mail 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.
For more information, see I got the message "Email can't be sent, because it appears to be spam".
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.
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.
