Email verification What is it

If you are into email marketing, then you are probably working with subscriber bases and trying to avoid bad email addresses.

An email address database is a list of recipients to whom you send emails. In other words, it is the basis of emailing, because the quality of email depends on whether it will get up into Unsorted or Spam.

To prevent your mailings from encountering Spam, it is imperative to verify email address. Read the article and find out how to check if an email is valid and why fake email lists can cause problems for your ad campaigns.

Why shouldn’t you neglect email validation?

Sending emails without verification is a waste of your budget, the risk of being blacklisted, blocking your account by providers and your tainted reputation.

If you are in doubt if you need to check your email list for relevance, here are some reasons to make sure that fake email verification is necessary.

Reason 1: the relevance of email addresses

Every year, 22.5% of email addresses lose relevance. For example, when people change jobs, and their work emails are deactivated.

If you do not regularly check the validity of email addresses, with time the Bounce Rate can grow to a critical 22%, and this is 10 times more than the acceptable level! So you will have to know how to verify email addresses later. We advise you to check your mailing list at least once a month. So you will be sure that you send emails to real email addresses and your followers receive information from you.

Reason 2: the number of hard bounces needs to be reduced

Hard bounce 一 it is when a letter is not delivered and is returned to the sender, because the recipient’s email address is invalid (non-existent). An increase in the bounce rate lowers your reputation, and you risk being blacklisted. It is better to know how to check an email, rather than suffer from the consequences later.

Reason 3: improve email deliverability

To filter out non-existent and invalid emails, use email verifier professional. This will ensure that your email list is up-to-date. This will improve deliverability and build a good reputation.

How to check a list of email addresses for validity?

First of all, you need to know what is to verify. And when you have a mailing list, you are ready to discover how to check if emails are valid.

So that after verification the mailing list contains only valid addresses, Atomic Verifier Online has a two-step verification. It includes:

Syntax checking: email addresses for the presence of the “@” symbol and for valid characters. Validate your email address here to exclude addresses with a syntax error: vika!?@%mail.ru., liza # mail.com. Email Verifier Online — Check Email Address Validity Online

Domain checking: a connection is established to the DNS servers, and the domain name of the email addresses is requested (for example, domain.com is checked to determine if the email address anna@domain.com exists). In other words, if no such domain exists, the email will also be invalid.

Checking the email address using the SMTP server. The Simple Mail Transfer Protocol (SMTP) server is a communication protocol or the technology behind email communication. The service tries to send an email to the server and processes the received response. Depending on the answer, the program will accurately determine the validity of the address.

To minimize the percentage of spam, email services collect information about each sender. The more emails you send, the more information they have to analyze. If the email ends up in spam, this is bad for your reputation. If the user clicked “this is not spam” 一 it is good. If your emails are opened and read, that is also a plus. Time passes, and your domain has a certain reputation.

You can manually check and identify emails with syntax errors, but there are also emails with non-existent domains. Imagine that you have to send a letter to thousands of addresses. It is unrealistic to define them manually. Save your time and money by using Atomic Verifier Online.
