Real-Time Email Address Existence Validation

Today we launched a new and important parameter to evaluate spambots. According to our statistics, almost 30% of all spam requests are made with fake email addresses, i.e. such addresses do not exist.

Previously, we could only check the existence of emails after the fact and use these data in the future; now we have started checking emails in real-time.

This new feature of CleanTalk grants the ability to check email addresses for existence in real-time.

Non-existing email addresses also entail several other problems for website owners:
• You can never contact them by email,
• The client will never receive any notifications from you (account activation letter, password recovery, email distribution, notifications, etc.),
• If you use email marketing for your clients, then a large number of nonexistent emails in the mailing list may result in your IP address being added to various blacklists of email servers.

Checking emails for existence is available for all anti-spam plugins and is included in the standard package.

You can leave a comment below or create a private ticket here.

We will be happy to answer your questions.

    Can you make a plug-in for “Email Subscribers”?

  5. Serge Baburin says:

    Anti-Spam plugin can check the submission form so it will check emails of subscribers for existence

    You forgot to mention whether this new ’email verification’ protection is automatic, or if we have to enable it. Let us know, please.

    What happens when in real time it detects a comment form with an invalid email address?

    Does the person completing the comment form get immediate notification?

    Or, does the site administrator receive notification?

    Does it prevent the comment from being posted to the website?

    Is there a way to turn this feature on or off?

  8. Sounds like you are making some serious progress guys – thanks for the update. I’m sure it is going to prove very helpful.

    email verification is automatic. This check is on the server’s side.

    When this filter triggers it’s equal to blocking spam user. The comment will be blocked, the request will be saved in CleanTalk logs. We can lower this filter for specific service.

    We always strive to improve our service.

    I have a Mailchimp signup form on my site. Can CleanTalk keep the fake emails from getting into my Mailchimp list? They seem to sign up and then “click” every link in the email I send out.

  15. Clean Talk doesn’t seem to be working for my site. When I try to go to my site from my phone it always redirects to some spam site. Not sure if I did something wrong in setting it up but it’s not working for me.

    Thanks!

    How is it checking? Is it sending an email to the suspect email? If so, what email is it using to check?

  18. Serge says:

    Hello.
    No, we do not send a test e-mail. We use HELO/EHLO requests plus our own method.
    Thank you.
