What Are Email List Cleaners Used For?

As their name suggests, email list cleaners are used to remove invalid addresses from mailing lists. Many marketers use a list cleaning service and an email address tester to avoid sending messages to invalid addresses, which can have many negative consequences. For starters, the fewer emails you’re able to successfully deliver, the lower your email deliverability rate will be. If you allow it to become too low, your ISP may think that you’re sending out spam and block list you, stopping your marketing efforts in their tracks.

Even if you avoid being block listed, any decrease in your deliverability rate is guaranteed to impact you financially since virtually all the major mail service providers charge based on the size of a list.

Last, but not least, not eliminating invalid email addresses using an email list cleaner tool can screw up your key email marketing metrics. When your metrics are incorrect, you may think that you’re doing something wrong, when that’s not the case at all. If you don’t realize what’s going on, you can easily spend a lot of time and effort trying to improve what doesn’t actually need to be improved.

Fortunately, there are many free email list cleaning software tools to choose from these days. So, you can be sure that you have a valid email address for each subscriber on your marketing list. You just need to know how to distinguish those that deliver great results from those that are best avoided.

How to Choose a Free Email List Cleaner?

When choosing how to verify email list addresses and which service to use, it’s easy to focus only on the number of free email verifications, which typically range from 100 to 1,000. However, there are many other factors that are just as important, including:

By keeping in mind these selection criteria, you shouldn’t have any trouble selecting a list cleaner that is capable of significantly improving email deliverability rates.

Best Free Email List Cleaner - FAQs

What is the best free email verification service?

Based on our experience, as well as online reviews published by real users, the top 5 best free email verification services are ZeroBounce, NeverBounce, Bouncer, EmailListVerify, and DeBounce.

How can I find the owner of an email address for free?

You can often find the owner of an address by entering the address into a service that provides reverse email searches, such as the one from AddressSearch.

How do free email list cleaners differ from the paid ones?

Free email list cleaning tools can typically verify only a relatively small number of addresses, such as 100. On the other hand, paid email verification services are happy to verify as many addresses as you’re willing to pay for.

What happens if you send an email to an address that doesn’t exist?

When you send a message to an address that doesn’t exist, the email server that the domain (the part that comes after the @ symbol) is associated with responds with a 500-series permanent error status. If the email domain doesn’t exist as well, your own mail server will bounce the message back to you, informing you that it couldn’t be delivered.

How do email list cleaners work?

Email list cleaners remove addresses from your mailing list that are invalid. These addresses may be inactive, canceled by the owner, or contain syntax errors. After the service identifies the invalid addresses and removes them, you’ll have a list that returns effective and profitable interactions with your subscribers.

How can I clean up my email list for free?

If you want to clean up your marketing list for free, you could do it yourself. This would involve looking for undeliverable addresses, spam-like addresses, duplicate addresses, and addresses with the wrong syntax. However, you’ll need to decide if the time you’ll spend on these tasks is worth it. If your list is small, several services offer a free account that provides you with a limited number of verifications and may limit the other features it offers.

How much does it cost to clean an email list?

The price you’ll pay to clean your list will depend on the service you choose and the level of service you select. Prices start as low as a few dollars a month. Some services offer a specified number of free verifications or a free account. The free services may be limited. If a service offers free and paid services, taking advantage of its free service is a good way to determine if the service will work for you.
