Best Email Checker and Validation Tools for 2024

and • 11 minutes READ

Do you know there is a way to improve your email deliverability, low open and click-through rate, and even ROI? Professional email marketers across all niches are perfectly aware of the impact that a healthy subscription list and good sender reputation can do. According to studies, these two decide whether your subscribers open the email and follow the lead or not. There are many ways to improve them, and an email checker is one of the most valuable solutions.

The average global inbox placement rate, representing the percentage of emails that successfully reach recipients’ inboxes, is around 85%. However, this rate varies by industry, country, and email service provider (ESP). The sender’s reputation significantly impacts deliverability rates. Senders with a good reputation, as determined by factors like low spam complaint rates and high engagement, can expect inbox placement rates above 90%. On the other hand, those with a poor reputation may have inbox placement rates below 50%.

The email checker does not need a special introduction. It does what it says – validates emails. However, there’s more to this than meets the eye. Depending on the platform, apart from locating and removing invalid, dangerous, temporary, or duplicate emails, it may also do these tasks:

  • Detect email traps
  • Indicate and delete emails with hard bounces
  • Validate syntax errors and locate spam words
  • Test responsiveness, mobile-friendliness, and accessibility of digital newsletters
  • Check up on whitelists and blacklists
  • Verify the receiver’s domain
  • Generate detailed reports

Not only does it scan your email list, newsletter design, and even campaign using a variety of different checks, but also it removes possible mistakes, issues, and flaws and improves the overall email marketing campaign and relationships with clients.

To find the best solution for your team, check out our list of the best email validation tools in 2024.
