Why is it important to maintain list hygiene?

If you keep the list of your email subscribers updated, here are the benefits you will get:

  1. You will have a better sender reputation.

  2. It follows from the previous point that your deliverability will increase as well.

  3. Your domain won't appear on blacklists.

  4. You will not only make fewer efforts but also reduce the expenses for your email campaigns.

  5. Save your mailings from lost leads.

When is it necessary to do the email list cleaning?

You should consider doing list cleaning if:

  1. Twice a year to remove inactive contacts.
  2. After every email campaign that you send — you need to remove those subscribers who got on the black list or unsubscribed from you.
  3. You didn't use double opt-in registration — new subscribers have to confirm their email address by clicking a link in the inbox.
    Verification emails as a way to improve email deliverability
  4. You collect the contact information manually, which means there might be plenty of typos, other mistakes, or duplicate email addresses.

If you send emails to lots of outdated email addresses in your contact list, your email provider can block your email campaigns. But don't start worrying: all you need is to check the contacts via email verification services (also available for bulk addresses) and use email cleaning services to remove spam email addresses. It will also prevent you from cases when the email bounces.

Scroll down to get to know more about different services which provide email list cleaning and choose your favorite.

What can I check with an email cleaning service?

Here are a few common functions of email list cleaning services that might be of use for you to detect the following:

What should you do before cleaning the email database?

There are two simple steps you need to take before you clean your email list and remove all inactive subscribers:

1. Send a test email campaign

Before you delete all the data of your disengaged subscribers, it's critical to try and re-engage inactive subscribers to see if you can bring their attention back to your mailings.

In the first email you may mention that, for example, a customer hasn't opened your mailings for a long time and ask if they are still interested to hear from you. The template should be simple, including only a few lines of text and Yes/No buttons.

In the second email, you may tell the subscriber they have been inactive for a while and you had to remove them from your contact list. But if they like, they can re-subscribe at any time.

Give them this opportunity right in the email.

Example of a re-engagement email

2. Check for soft and hard bounces

If an email bounces, it doesn't always mean that the email address is incorrect. Sometimes there might be a few temporary issues on email servers, but the contact information is still valid. Such cases are called soft bounces. Usually, email service providers repeat sending it several times until the message finally gets through.

Another type of bounced email indicates that something's wrong with the email address. It might be written with a typo or not exist anymore. Hard bounces also may take place if the recipient's email server blocks you as a sender.

In case of hard bounces, if you cannot contact a person any other way, you should just remove their contact as part of the cleaning process.

Final thoughts

As you may see, maintaining the hygiene of your database is essential for email marketing. However, thanks to various email list cleaning services, you don't have to do any extra marketing efforts.

We would like to share a final piece of advice for you:

  1. Use double opt-in registration to check the emails immediately and single opt-out unsubscription to let unengaged subscribers go.

  2. Check if you can still re-engage your audience with a test email campaign before removing inactive emails from your database.

  3. Verify the email addresses in real-time while your website visitors are filling out the registration form.

  4. Check your database with one of the email list cleaning services on a regular basis to maintain your sender reputation and make sure you won't miss any leads.

  5. Have a look at your email marketing statistics to see if there are any patterns. The most important metrics are the number of unsubscribes, opening and click-through rates, and spam complaints.

Thank you for choosing us to update your knowledge about email list cleaning and email marketing overall. We do believe that our research will help you improve the results of your campaigns and increase the conversion rate. Feel free to choose any of the above-mentioned practices or services and you will immediately see the results.
