Keeping a clean email list is vital for the success of your email marketing efforts. Scrubbing your email list periodically and removing email addresses you don’t need can help you improve your deliverability and facilitate proper segmentation.

Here are five tips to get a clean email list and the best services for email list scrubbing.

1. Remove duplicate email addresses 

Sooner or later, we all get duplicates in our email lists. Users may enter their information more than once or through multiple sources. 

Duplicate data can be costly to host and can waste time and resources. It can also lead to sending duplicate emails to users, negatively affecting your brand’s reputation and success rate.

Make sure to scrub your duplicate emails off your email list periodically and add filters to avoid adding duplicate data.

2. Remove spammy or fake email addresses

Bad data in your email list can spoil your efforts, sometimes long after getting rid of it. Spam traps and fake email addresses can affect your sender’s reputation, directly impacting your email deliverability.

These addresses can be an issue, especially if you’re buying leads from services without a data-quality guarantee, some of which may sell inaccurate data in their email lists.

Make sure to remove spam email addresses from your list with an email verification service to keep your newsletters from falling into people’s spam folders. 

3. Verify emails before using them in email marketing campaigns

Invalid email addresses can also affect your sender reputation. That’s why it’s best to run them through email verification services to remove all invalid addresses while building your email list

If only a few users join your platform daily, you can manually validate each one before adding them to your email list. If you lack the time or resources, you can use an email validation service’s API to validate emails as they’re entered automatically.

If you want to make sure you’re buying high-quality data, get it from providers that offer a data guarantee. If not, always use an email verification service to ensure all emails are valid and belong to real people.

4. Request inactive or low-engagement subscribers to opt-in again

Not everyone opens their email marketing messages. And that’s to be expected. However, keeping inactive subscribers on your email list can also negatively affect your efforts and your budget.

Removing inactive subscribers can prevent spam complaints from users no longer interested in your products or services.

Access your email marketing statistics to find users who haven’t engaged with your marketing efforts in a long time. Segment that audience so you can place your long-term, unengaged subscribers into separate campaigns to either reactivate them or remove them from your email list.

5. Use an email list cleaning service

If you’re looking to validate an email list you just bought or don’t have the time or resources to do email scrubbing yourself, you can use email scrubbing services. 

Email scrubbing services quickly and automatically validate your whole list. Some can also check your list’s syntax errors and correct obvious typos to prevent invalid email addresses from being removed.

These services validate all emails and remove spam traps and fake email addresses, ensuring your list contains only valid addresses.

This is all done within a matter of minutes.

Some services do more than just email validation, offering to correct some emails and remove duplicates from your lists. You can also use more advanced tools to generate user data as you validate your email list, enriching it with valuable information to better cater to their needs.

Here are answers to questions about email list cleaning tools:

What does it mean to clean an email list?

Cleaning an email list typically refers to removing all invalid data from it. The aim of cleaning email lists is to remove invalid email addresses and ensure all addresses are valid before using them in email campaigns. Email list cleaning can also mean ensuring all subscribers still want to receive your emails. This ensures your audience comprises engaged users who open your emails rather than passive subscribers who will no longer interact with your brand.

What does a clean email list look like?

A clean email list is an email list that only includes valid email addresses from invested users. Clean email lists have a low number of email bounces and can be used in any email marketing strategy, avoiding spam folders. Clean email lists also lack duplicate information to prevent sending double messages to users.

Why is cleaning an email list important?

Cleaning an email list and keeping it clean achieves a few key things. A clean email list ensures a better sender reputation, translating to higher deliverability and a lower bounce rate. A clean email list also increases the likelihood of success of your email marketing efforts while keeping costs down by ensuring you’re not storing any useless data.

What are the risks of not cleaning an email list?

Not cleaning your email list periodically can quickly lead to bad deliverability rates. Not validating email addresses in advance opens the door to spam traps and other bad addresses, which are made to keep spam from reaching users. Finally, having an old email list with uninterested users can open the risk of spam complaints, affecting your deliverability even more.

How often should email lists be cleaned?

The frequency will likely depend on your email list’s size and fluctuation. However, an email list should be cleaned approximately every six months. With fast-changing email lists, email scrubbing should be done more often to prevent invalid email addresses from staying in them. An email list cleaning service can simplify this process or even perform it automatically.

Is it possible to properly clean an email list for free?

Yes, you can use the free tier of an email list cleaning service to start cleaning an email list for free. Some tools even offer a free account or limited free bulk email verification tools, which allow users to verify emails quickly and effectively.


Keeping your email list clean is vital to your email deliverability. The right email list cleaning service can make the verification process quick and easy. Using tools like UpLead, you can do far more than clean your email lists.
