Why do we need email verification?

After a lead generation, verification of email addresses is the most crucial element of email marketing and e-sales. That is why it is very risky to neglect this procedure. Good contacts will definitely be able to accept your emails so that the inbox placement rate of your mailings will remain safe & stable.

If you do not regularly check whether the mail from your contact base exists, the bounce rate for your mailings will drastically increase and exceed the acceptable level ten times after a year. As a result, your reputation on postal services will be severely damaged.

Address syntax and format checking

The email marketing software checks:

  • Errors before and after the @ symbol. The first part of the address is called local, the second 一 domain: gmail.com, mail.ru. For example, a user can skip a letter in a domain name: “.co” to “.com”. As a result, invalid address in the list.
  • Duplicated emails. It may happen for various reasons. First of all, the human factor:
    – you added contacts manually;
    – you have combined several bases into one;
    – while filling in contact details, you created a new one instead of choosing an existing client card;
    – two managers collaborated with the client, both entered the data.
    – the user subscribed to the newsletter again, made a mistake in the name and used the same email.
  • Spam traps. These are the addresses used by postal services to check for unscrupulous senders. Because of such a contact in your address book, you can get blocked by the mailing service. The validator program checks the mailing list subscribers of known spam traps and shows the matches.
  • Service addresses, or role-based addresses. How to check if the email address is valid on that occasion? This is the mail that is assigned to a group or department in a company. For example, admin@, support@, hello@. A large number of complaints and unsubscriptions come from these addresses.
  • Disposable emails 一 addresses for temporary using that do not require registration. People use them in order not to receive mailing from companies and not to give access to the main ones. The validator finds such mail and offers to delete it from the contact database, so it increases email deliverability.

Domain and server verification

Mail eXchanger (MX) is a DNS record that points to a mail server. How does email verification work? A domain without this record will not accept emails. The validator checks the address for the presence of an MX record and its correctness.

Confirmation of mailbox activity

Using SMTP communication or mail transfer protocol, the validator sends a request and checks whether the contact is active or inactive.

How to tell if an email address is valid

Perhaps the most straightforward way how to check if an email address is valid is to simply send an email to it. However, there is a more professional and optimized way to do that in bulk rather than just verify the validity of email addresses by sending tests email which is problematic and time-consuming for huge contact lists processing.
