But sometimes, that’s easier said than done. 

This time, we will provide you with a deep overview of the tools that offer the best email list cleaning services that help you remove outdated and invalid emails quickly and easily.

We discuss their pros, cons, customer support, and pricing and tell you which tool is best for what kind of user.

What to look for in an email list cleaner?

How clean an email list is directly impacts the effectiveness of your email marketing campaigns. 

Here are a few elements you should pay attention to when looking for an email list cleaner to guarantee your efforts are fruitful and efficient.


Accuracy is non-negotiable for email list cleaning. The primary goal is to sift through your list to identify and remove all invalid and duplicate email addresses, and the sneaky spam traps that can tarnish your sender’s reputation.

A top-notch email verification service can do it all and meticulously verify addresses to ensure your list contains only valid ones. 

This function is also crucial in reducing bounce rates and avoiding spam complaints, which in turn, improves email deliverability.

Look for a tool that boasts a high accuracy rate. Otherwise, you will put the effectiveness of your marketing campaign at risk of failure.

Speed of verification

This is also a critical factor, especially when you’re operating on tight schedules or have large volumes of bulk addresses to process. A swift email cleaning service ensures that your campaigns are not delayed due to prolonged list cleaning times.

The key is to find a tool that is fast enough and accurate enough to maintain a high level of quality. For example, Bouncer verifies 200,000 emails in an hour per client.


Pricing is always a hot topic, and when it comes to email list cleaning tools, flexibility in pricing and getting value for your money are paramount.

Whether you’re a small business or a large enterprise, find a service that offers tiered pricing plans and can accommodate your specific needs and budget. Look for software that provides a clear breakdown of what you’re paying for, such as the number of email addresses verified or cleaned.

Most importantly, look for a tool that offers pay-as-you-go rates and monthly pricing plans – like Bouncer does – as your needs may change in the future.

Integrations with email marketing tools

Check how easy the tool is to connect with email marketing tools. Having integrations is so beneficial, as they reduce manual work, minimize the risk of errors, and ensure a smooth transition from cleaning to campaign launch.

An email platform that offers robust integration capabilities with other popular email marketing services (and not only) is a boon for those marketers looking to maintain efficient and effective email marketing strategies. 

Just look at Bouncer. Our tool can be integrated with apps like Aweber, Constant Contact, Klaviyo, LemList, Mailchimp, and Moosend. With such external applications, our platform becomes even more powerful and offers more possibilities.

Customer support

Stellar customer support can make a world of difference. In cases when you encounter technical issues, have questions about the cleaning process, or maybe need guidance on best practices for maintaining email list hygiene, responsive support is invaluable.

For example, Bouncer offers contact through channels like e-mail, chat, phone, or online meetings. Thanks to them, our support team can help you run more successful email marketing campaigns.
