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.
