How Email Verification Service Works
Email Verification Service can help solve a lot of mailer problems. Within a year 22% of email addresses go bad. If you have a 100,000 mailing list, approximately 20,000 of those are undeliverable by the following year.
That is where an email verification service comes in. Email verification services help you clean up your mailing list by eliminate the inactive, risky and fake email addresses that can ruin your email deliverability statistics and also help to protect the reputation of your outgoing mail server.
There are three steps in an email verification service; syntax and formatting check, domain server confirmation, and mailbox confirmation.
Step 1: Syntax & Formatting Check
In the first step, email verification service can instantly check your mailing list and subject it to the standard email formatting requirements; the provider formatting requirements for several email providers.
The difficulty of email formatting rules makes it almost impossible for a list to be check manually. Issues such as empty characters or missing @ symbols are identified within a fraction of a second in both the local and domain part of the email address.
Step 2: Domain Server Verification
Our email verification service makes positive that the domain name is active and valid by checking the DNS records and tests the mail exchange (MX) to ensure that it is set up correctly to receive mail.
Step 3: Mailbox Confirmation
And lastly, verifying that the specific mailbox even exists is the most important step of the email verification process. The verification service utilizes SMTP protocols to contact the mailserver and confirm that the mailbox can receive your messages.
According to an article on Campaign Monitor, “For every $1 spent on email marketing, you get $44 in return,” says Exact Target. That’s an unbelievable 4,000 return on investment according to the Direct Marketing Association. That’s crazy, provided if you have a good quality lead source. But unfortunately, email data does not have an endless shelf life.
An unverified email list leads to poor deliverability and will result in an unsuccessful mail campaign. Verifying your email list regularly, at least once or twice a year, or before sending as large email campaign will keep you away from those issues and will get you ahead of your business plans.
