It comes with many features for cleaning email lists and verifying email addresses. Over 125,000 users trust NeverBounce, so it’s a pretty popular tool that validates emails, lowers your bounce rate, improves email deliverability and more.

The most prominent clients of NeverBounce list cleaning services are Doordash, Uber, Dell, and Indeed.

But does it make it the best choice for you? Let’s check the NeverBounce review in detail. 🔍

🚀 NeverBounce features

Bulk email list cleaning

It is an essential tool for maintaining the high quality and effectiveness of your email campaigns. NeverBounce goes through your list and removes emails that:

  • are outdated
  • have typos in them
  • are spam traps
  • have invalid email syntax
  • and more, all so that you’re only sending to real recipients via email 

With NeverBounce, there are two methods of cleaning. You can either upload a file to the NeverBounce app or use their dedicated API for real-time cleaning.

Real-time email verification

As emails are submitted, the system checks them for validity, precision, and potential risks. It’s a simple process:

  1. someone lands on your website
  2. they enter their email to opt in to a mailing list (or grab a demo or some sort of lead magnet)
  3. NeverBounce checks their email for validity right then and there
  4. if the email is valid, it is added to your list and email database so you can target them with email marketing campaigns
  5. if not, the user is asked to add a different email address

This feature is extremely important to enhance your email marketing efforts. Invalid email addresses on your list may make your sender’s reputation suffer. And as a consequence, your email reach may become limited and shrink in performance, so your campaigns and income.

🎯NeverBounce accuracy

Compared to NeverBounce alternatives, the accuracy of this tool is pretty low – only 93%. And low accuracy provided by an email verification tool can spell trouble for your email marketing strategies.

You’ll end up sending emails to invalid addresses, hitting spam traps, and annoying email recipients. Again, your sender’s reputation may be at risk because of poor email quality. The email list cleaning services may be fast, but if the email validity check has low accuracy, email marketers using NeverBounce are going to have a hard time.

NeverBounce validates most email types, such as Gmail, Yahoo, and more. However, users report that the results on Yahoo email addresses are not always reliable.

Also, when talking about the numbers, NeverBounce declares to remove up to 99% of bounced emails, which is quite a good score for email marketing services.

🏃 NeverBounce speed

The tool can verify 10,000 emails in less than 60 minutes, which is quite fast, but not the fastest. If you have a large list and you want to send some marketing emails, you may need more speed.

If your email list is long, speed is quite important here. Otherwise, with a slow tool, you’d end up waiting hours which may affect your workflow.

💵 NeverBounce pricing

NeverBounce comes with a “no packages” approach. Charges are based on the number of emails requiring verification on a pay-as-you-go basis. Monthly invoicing is an option.

Just to give you an idea:

Up to 10,000 emails will cost you around $50.

Their pricing system? Check this out:

Emails Price per email at NeverBounce
up to 10,000 $0.008
up to 100,000 $0.005
up to 250,000 $0.004
up to 1,000,000 $0.003

More emails, less cost.

If you’re looking at verifying over a million emails, you can get in touch with the NeverBounce team and ask about their enterprise solution.

NeverBounce customer support 

So far, NeverBounce seems like a pretty decent tool on all fronts of email verification. Customer service is a mixed bag, however. There are reviews of all different types once you start doing some proper research.

  • “Terrible” support, “ issues are not proactively reported,” and “inaccurately tag” don’t sound fun.

    But good reviews are also evident and here is one from

    “What I also appreciate is the option to extract whatever list segment you need and identify over 25 advanced data points that were detected in the cleanse. This means you can quickly identify free email hosts, role accounts, data with incorrect syntax, valid DNS/MX records, etc.”

    Be careful with segments, though!
