With so many different email verification software available, figuring out which is right for you is tough. You know you want to ensure the accuracy of your email contact lists more efficiently but need to figure out which tool is best. I've got you! In this post I'll help make your choice easy, sharing my personal experiences using dozens of different email verification tools with various teams and accounts, with my picks of the best email verification software.

What Is Email Verification Software?

Email verification software is a tool that checks and validates email addresses on a mailing list. It ensures that the emails are correctly formatted, belong to a valid domain, and are capable of receiving messages. This software scans and analyzes email lists to identify and remove invalid, non-functional, or risky email addresses, thereby cleaning and maintaining the quality of the email database.

The use of email verification software leads to improved email deliverability by significantly reducing bounce rates. This enhances the effectiveness of email marketing campaigns by ensuring messages reach active and valid email addresses. It also protects the sender's reputation by avoiding sending emails to spam traps or invalid addresses, which can harm deliverability and sender credibility. Additionally, it helps in saving costs associated with marketing to non-existent or unengaged contacts and increases engagement rates by targeting a more accurate audience.

Because there are so many email verification tools out there, I rounded out my list with a few of the runners-up. While they may not be in my top ten, they’re still worth checking out.

Selection Criteria For Email Verification Software 

If you’re wondering how I selected the best tools for this list, you can find my selection criteria and explanations here. Check out this short summary of the main elements that affected my decision and what I used to develop my list of the best email verification software for this article:

Core Functionality

Every email verification software must have some basic functionality that delivers the results you need, including:

  • Allowing users to upload emails and lists directly onto the platform
  • Scrubbing lists for bad addresses or unusable addresses
  • Ensuring you can download the updated, scrubbed email list

Key Features

To provide you with the core functionalities listed above, each software has a list of features that make your life a little easier. While some of these features may vary a bit in name, you’ll find that they offer similar results.

  • Bulk and individual verification: For more versatile operations, you want a tool that can handle your biggest lists, as well as spot-checking for single emails.
  • Tiered verification process: A catch-all process that goes through syntax errors, gibberish, domain existence, and MX records.
  • Import and export features: This feature ensures you can upload a list from a spreadsheet, CRM, or other source for authentication.
  • Real-time verification: Guarantees that you’ll only be getting fresh results, not those based on old data.


Your marketing team shouldn’t be wasting weeks integrating email verification into your workflow, so I prioritized tools that were simple to learn and navigate. While there is always a learning curve, all the software options on my list have simple user interfaces and intuitive organization.

Software Integrations

Because email verification is likely part of your marketing operations, I looked for options that focused on integrating with the most popular CRMs and sales tools. You’ll see that I noted the most common available integrations for each platform.


There are several pricing models available for email verification software. If you’re an individual or small organization, the pay as you go structure might be the right choice for you. Any company that has a heavy focus on bulk email outreach or B2B prospecting would be better served by a monthly subscription that has unlimited verification support.

You’ll find that minimal email verification tools can be found for free, while paid plans may range anywhere from $30 - $1,000 per month, depending on how many credits you purchase or how many emails you need to verify in any given month.

People Also Ask

If you’re still trying to figure out whether email verification software is the right choice for you, I have a few more answers to the most frequently asked questions. Check them out below.

What are the benefits of email verification software?

So other than the obvious benefit of actually reaching the people you’re trying to contact, an email verification tool decreases bounce back rate and ensures your reputation as a sender is high among ISPs. With a better reputation, you can expect your emails to make it out of spam and into the main inbox because you have a higher deliverability rate.

Who uses email verification software?

Email verification is a process used almost universally across sales and marketing. Whether you’re checking a new user sign-up email or purchasing contact lists that you want to ensure are authentic, anyone who has any sort of outreach needs to guarantee the email addresses of customers, prospects, and partners.

How do I verify an email address?

Email verification is typically a tiered process that goes through several steps to ensure your email lists are valid. After these basic steps, some platforms also offer additional insights into your data, including removing bad-fit buyers or identifying buying signals.

  1. Scrubbing spam traps
  2. Checking for formatting and syntax errors
  3. Reviewing DNS records for correct domain name
  4. Ensuring a domain exchange server can actually receive emails
  5. Using the SMTP protocol to check the mailbox

Some platforms offer even more steps with eight or nine total verification methods.
