Tried & Tested: 5 Premier Email Verification Tools

Not sure whether your deliverability standards are foolproof? Try these five premium email verification tools and overcome pre-send anxiety....

 As an email marketer, your job isn’t complete until at least 24-48 hours after hitting the send button. Once the campaign is live, you anxiously wait to see if your emails have been successfully delivered to your subscribers’ inboxes, followed by whether or not they engaged with your message. (Wait, did we just describe ourselves?)

But what if you could determine in advance whether an email meets deliverability standards across ISPs? Imagine being certain that the welcome email your team has worked so hard on will reach the intended recipient’s inbox, not their spam folder. 

This is where email validation tools can help you. These are highly sophisticated tools that perform all-round deliverability checks before you send emails. 

With hundreds of tools available, testing each one yourself is impractical. But don’t worry! Our research team has evaluated numerous options and curated a list of the five best email verification tools based on accuracy, speed, and cost.

1. Unspam

The first email verification tool on our list is Unspam. Equipped with all-round email deliverability checks, the tool is intuitive and requires minimal process clicks. It offers:

It’s hard to say which tool fits your brand perfectly. But you can start here: While choosing among these five tools, ask yourself:

  • Do I have the necessary team/departmental resources to adopt a new tool?
  • Does the target for the current quarter require trying out a new software?
  • Do I have the budget for this?
  • Does the tool offer seamless integration and extensions?
  • Can the tool handle large email lists?
  • Does the platform provide a custom plan for large agencies?
  • Which is better for me: the credit system or the standard monthly tiers? Does the tool even offer that option? 

So those are some of the ways you can sense a path toward the right choice. Bear in mind that if you are using a dedicated email service provider for your deliverability checks, you might not need to use these tools exhaustively. You should find the right balance between your requirements and expectations from multiple platforms.
