Free Email Testers

Email marketing is undoubtedly one of the top channels to drive traffic, increase engagement, and generate business. For this reason, sales and marketing professionals are constantly involved in building mailing lists. If done correctly, the ROI from email marketing can be humongous.

And yet, some of you probably saw returns in this arena that were far below your expectations. There could be several different reasons behind that, but one major culprit might be the quality of your email contacts or subscribers.

If your mailing list has email addresses that are temporary, role-based, spam traps, or simply incorrect, your email deliverability is very likely to suffer. And that will pull down your ROI, too.

So, what can you do about it?


What is Email Verification?

Email verification is the process of verifying the quality and accuracy of an email address. Email verification will remove addresses that are unsafe to deliver.

High-quality data plays a key role in the success in digital marketing. The result of validating a mailing list will tell you all about the quality of your data. If the quality is high, you will know you’re on the right track.

However, if you see a large number of unsendable or incorrect addresses, you will know that there’s a need to improve things. The result of the email verification is pretty detailed. It will tell you which address is undeliverable, which is role-based, which one is accept-all, and so on. Equipped with this information, you can choose to remove addresses that don’t hold any promise of being delivered safely.

As such, you will practically see all your outgoing emails are being delivered. The essence of email verification lies in the fact that with a cleaned mailing list, you’ll see little to no email bounces.

Additionally, to those who are wondering why email verification is important, the answer is that because you’re sending emails to fewer and a selected group of people, the costs associated with storing and sending out emails go down.

With this in mind, we have listed a bunch of free email testers that you can explore while you’re at it. Without further ado, let’s dive in!
