Any company that sends mass mailings or uses email marketing, it is necessary from time to time to validate the contact base. Special services come to the rescue – email-validators. On sites that check emails, you can check:

  • Syntax – checking the spelling of addresses, including the special signs “@”, etc.
  • Duplicates – checking for email addresses that are repeated;
  • Spam traps – electronic mailboxes that send advertisements or spam;
  • Contacts from which there are a lot of complaints about spam;
  • Fake boxes – checking for mail addresses that are created for one-time use;
  • Role-based Addresses – emails that are not created for a specific person, but the position of an employee; such addresses often have a high number of unsubscribes;
  • Mail eXchanger (MX) – a mailbox registered on a domain without an MX record cannot receive messages;
  • SMTP server – this function shows whether an email address exists or is already abandoned by the user;
  • Mailbox activity – shows how often a user visits this mailbox.

This is not a complete email verification list, but even these items are enough to understand which email addresses and people you have to deal with. Check the email if email addresses were collected using questionnaires. A person who manually fills in a document may make a mistake in writing his data.

Remember that if you have an unverified contact base, this is:

  • You can spend money in vain;
  • Mail servers can add your newsletter to the blacklist;
  • The fall in the reputation of the sender;
  • Lock in ESP.
