25 best email verifier services: Review and comparison

Email marketing still works, and it relies on validity of email database you’ve collected. How good are your products and how do you tell people about them also matter, don’t get us wrong. Though nobody wants to go into a blacklist of spammers because of high number of bounced emails. How do you check if emails are real? How do you check 1000 of them? Luckily, a solution exists – email verification service.

There are dozens of them actually, and what they do is determining whether email addresses are valid and deliverable. This, in turn, helps to lower the risk of bounces and improving your marketing campaigns. We’ve decided to do a service to you, marketers and CEOs, by reviewing vendors and selecting the best email verifier services.

We are compiling a list of top-25 with key features, pricing and links, and finish it up with a comparison table. Before that, one quick piece of information to be armed with.   

What is email verification

Also known as validation, email list cleaning, email verification is a process that checks whether given email addresses are valid. It is an online SaaS type of service, typically by a hosted provider where you can upload a list in .csv or other formats. For validation it uses techniques like syntax check, domain check, disposable address detection, etc. Invalid emails are marked or deleted.

There are 2 types of email verification services:

  1. Real time verification through an API. A visitor from the web enters email address on a site and test is carried out. In few seconds a message appears with valid/invalid result. Usually, such online services have a limit of 5 to 10 entries at a time, and are free.
  2. Bulk email list verification. For cases when we’re talking about thousands-to-millions of addresses. Such email verifier systems allow you to upload a ready file (usually Excel type), wait while the list is checked, and download a clean list. Surely, you have to pay for it, while getting 80 to 98% accurate results.

Weighing in on pros and cons of bulk verification, the main benefits are:

  • Lower email bounce rate / higher deliverability rate
  • Keeping sender reputation and IP/domain score
  • Better chance of emails actually reaching people
  • Overall positive ROI on email marketing campaigns

We’ll just briefly highlight their key features and pricing, and you decide what’s best for you.

I used http://www.zerobounce.net and it is an amazing platform for online email validation that is created to ensure companies avoid email bounces. This is accomplished by identifying invalid, abuse, spam-trap, and ther hard bounce email addresses. They also provide a real-time API for email verification on your platform.
