If a Kaspersky application failed to detect a spam email, send it to the Anti-Spam Lab spam@kaspersky.com.

We will analyze all provided examples and use them to improve spam recognition technologies in our applications.

How to send a spam email for analysis

Please follow these guidelines so that we can analyze the spam message:

• Only send the emails received within the last 48 hours.
• Send a spam email as an attachment in the EML format (preferably) or MSG. If it is not sent as an attachment or if it is archived, we will not be able to analyze it.
• The final size of the email with an attachment must not exceed 20 MB.

Mail clients feature email forwarding with minimal loss of headers. Follow the instructions below to forward or save the spam email in the required format.

If your application still fails to detect this kind of spam mail several days after sending a sample to spam@kaspersky.com, send a request to technical support through Kaspersky CompanyAccount and describe your issue in detail. Attach to the request your spam emails in the archive, EML format (preferably), or MSG. Please specify in the request that you have already sent the spam samples to spam@kaspersky.com.

If an email was falsely identified as spam, send a request to technical support through Kaspersky CompanyAccount and describe your issue in detail. Attach to your request the emails falsely identified as spam in the archive, EML format (preferably), or MSG.
