Проверка email - будьте уверены что email реальный

How email checker is helpful for webmasters, website owners, email marketing services

Emails still stay the most reliable and most popular way to contact your clients. Emails are being used everywhere — sign ups and registrations, comments, website news subscriptions and so on. But besides the usual visitors, emails could be used by spammers, they use both real emails addresses and fake ones. This fact brings certain risks to any online business.
While planning an email marketing campaign, you have to be sure that your list of email addresses is correct.

1. Real emails weren't used by spammers. If it's the case then the email owner can report your mailing list.
2. Real email belongs to a spammer — you wasted your money, your letter won't be read.
3. Non-existent email — you have risks to be blacklisted.

All this could lead to problems: black lists, low rate of delivery, your letters could go directly to "Spam" folders.

According to the CleanTalk statistics, about 30% of email addresses that were used to spam websites are fake.

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.

CleanTalk email checker actually connects to the mail server and checks whether an email exists or not. Don't risk your reputation.

Each CleanTalk Anti-Spam Plugin supports Email Existence Verification in real-time.

You can also use bulk verification of email addresses for existence.

The email list will be checked according to the CleanTalk database. As a result, you will receive a list of checked email addresses, their spam status and exist or not. If some of emails have a status (-), it means that this email doesn't have any status/record in our database and in this case you should check it separately on this page.

Spam, Scam, and Phishing attacks

Spam Emails

CleanTalk’s email checker helps identify suspicious or previously reported email addresses before they interact with your website. It checks the email against CleanTalk’s global spam database, which collects signals from millions of websites detecting spam activity. If an email has been associated with spam submissions, abuse, or automated registrations, the checker can flag it as high-risk. Website owners can use this information to block spam registrations, contact form submissions, or fake accounts before they reach their systems. By filtering risky emails early, the tool helps reduce spam, protect user databases, and maintain cleaner communication channels.

Fraud and Scam Emails

CleanTalk’s email checker helps identify addresses linked to spam, scams, or fraudulent activity. It compares emails against a global database built from spam reports and suspicious behavior across millions of websites. If an address has been involved in fake registrations, scam messages, or card fraud attempts, it can be flagged as high-risk. This helps website owners block scammers early and reduce fraud.

Phishing Emails

An email checker can help detect potential phishing attempts by verifying whether an email address has been associated with suspicious or abusive activity across multiple websites. Before trusting a message, website administrators or support teams can check the sender’s email against reputation databases to see if it has previously been linked to spam, scams, or phishing campaigns. If the address appears in spam or abuse reports, it may indicate that the message is part of a phishing attempt. This allows organizations to flag or block suspicious communications before users interact with malicious links or attachments. Using an email checker as part of a broader security process helps reduce the risk of phishing attacks and protects users from fraudulent messages.

Email Checker API

The Anti-Spam API is a ready-to-use solution for filtering fake orders, sign-ups, contact messages, card fraud attempts, and more.

The Block Lists API is the second option and provides additional data about sign-ups, orders, subscriptions, surveys, quizzes, and other submissions. This API can be used alongside other anti-spam or security solutions on websites, mobile apps, and other online applications.

Both APIs are available after sign-up.
