Top 10 Bulk Email Verification and Validation Services Compared

What Is An Email List Verification & Validation Service?

Email list verification is a process of determining whether a list of email addresses are valid and deliverable. It is an address-by-address analysis of emails from the uploaded list, to identify their deliverability. It is offered as a hosted software/services.

What Is The Process Of Validating An Email Address?

The validity of an email address can be measured through a combination of several validation techniques, and internal databases check with some proprietary algorithms.

At the end of list validation process, invalid email addresses will be filtered out and the outcome will be a clean email list – validated and ready for marketing and business requirements.

Below is a detailed description of how entire email validation process works:

  1. Email address syntax check: This process will remove any improperly formatted email addresses. The email addresses are validated according to the IETF standards.
  2. Domain/MX records check: This process will check the DNS entries of an email address. When the domain is invalid or MX entry is missing, the process will mark this email address as invalid.
  3. Role-based Account detection: In this email validation process, role-based account email addresses such as [email protected], [email protected], [email protected], [email protected], etc. are detected and flagged as inappropriate for mailing list.
  4. Disposable email address (DEA) detection: Throwaway/disposable email addresses or junk collector email addresses will be detected and processed appropriately.
    These email addresses are used for one-time use to sign up or to bypass login form with providing a temporary valid email address. Disposable email address usually become invalid in few minutes or few hours.
  5. HoneyPot/Spam trap detection: This process will detect spam seeds, BOTs, honeypots, black listed or bogus email addresses.
    In this process, all the emails are checked against the known list of email address/domains used for trapping spammers.
  6. Checking DNSBLs and URI DNSBLs for blacklisting: A DNS-based blackhole list (DNSBL) or Real-time Blackhole List (RBL) is a list of IP addresses which are most often used for sending spam emails. A URI DNSBL is a DNSBL that lists the domain names which are found in the body of spam emails, but generally not found inside legitimate emails. In this process, email address or IP address is checked against the known DNSBLs and URI DNSBLs to trap spam networks.
  7. Final verification: This phase performs deep level SMTP verification on each email address. Each email address will be verified for mailbox existence without sending actual emails on that address.

Why Bulk Email Verification Is So Important?

Most of the online websites have web forms asking for customer details along with email address. During this form fill up, intentionally or by error, users may enter a wrong email address.

Building your email list by accepting such email addresses, your list will be filled up with inaccurate and undeliverable email addresses.

If you send emails to such email addresses, the ratio of bounce back emails will be much higher. This will negatively affect your mail server reputation, which is constantly monitored by Yahoo, Gmail, AOL, HotMail and other ISPs.

An IP address with the poor reputation may get blacklisted by popular email services like Gmail, Hotmail, AOL & Yahoo.

So, if you are planning to run bulk email campaigns like sending newsletters, identification and removal of invalid email addresses are essential.

Bulk Email verification service ensures that your email list is clean and properly validated which helps you reducing bounce back and save your hard-earned money and valuable time.

Validating email addresses also helps you maximizing deliverability of your email marketing campaign and helps you to separate the low-quality addresses from high-value contacts.

By using email list validation services you can enjoy peace of mind as you are only sending emails to the real users.
