3 Best Email Checker, Bulk List Cleaning, Verification Tools

In this list article, you will find top email checker tools to verify email addresses manually, automatically, and in real time.

You spend time and money buying traffic…

…not just to build an email list with fake details.

The best way of making sure your email list is cleaned is by running those email IDs through an accurate email verification service.

Why Should Clean Your Email list?

Whether you are a solopreneur marketer, business owner, or working for an enterprise-level company, you should use an email verifier service. Here are several benefits of using a list cleaning service for you.

  • Prevent fake signups – If you run a giveaway, for example, the chances are your campaign will generate a high amount of fraudulent signups normally.
  • Block signups with disposable email addresses – With the birth of disposable or temporary email services, people use them instead of the real ones. You must use a good email list checker service to identify those temporary emails.
  • Reduce your autoresponder or CRM software cost – Every fake email address costs you money.
  • Improve email deliverability – The fewer fake email addresses your email service provider has, the higher chance of your emails getting more opens and, therefore, a top deliverability rate. For instance, if you use Solo ads to build your email list, chances are your email list will get higher bounces (hard and soft), so it’s better to clean up your email marketing list from time to time.
  • Decrease bounce rate – Hard bounce rate happens when your contacts’ emails are invalid. You should verify those emails in bulk and remove any fake ones.
  • Increase your email marketing campaigns’ ROI
  • Protect your domain reputation score

Conclusion on best email checker tools

Qualifying leads should be one of the main priorities in your lead generation campaigns. Depending on your lead gen strategy, it can make or ruin your marketing campaign’s effectiveness based on the quality of leads.

For instance, if you are using CPA marketing to scale your lead generation process, one or two affiliates can really impact your business.

That is why you should consider utilizing a list-cleansing service to eliminate fraudulent email addresses.

In this post, I shared the best email checker and verification tools to validate emails in real time. Additionally, those tools let you bulk upload emails so that you can clean your existing emails from time to time.

Bulk email verification is really useful in scenarios such as after launching a mega giveaway because the chances are higher of getting a notable portion of fake email addresses in a sweepstake or a referral campaign.

What I suggest is using a tool like Integrately to verify emails prior to sending them to your marketing funnels. The setup will be similar to this:

Your landing page >> Integrately >> Verify emails through a tool mentioned in this post >> Send the data to your email service provider or CRM if leads are not fake.
