Email scrubbing is the process of cleaning your email list by removing inactive or unengaged subscribers. Over time - some people on your list may stop opening or clicking your emails. Keeping these inactive contacts can harm your email marketing results by lowering your open rates and increasing bounce rates.
When following email scrubbing - you should target the following types of contacts:
  • Inactive subscribers: Those who haven’t opened or clicked on your emails for a long time.
  • Invalid email addresses: Addresses that bounce back or are incorrectly formatted.
  • Unsubscribed contacts: People who have opted out but are still on your list.
  • Spam complaints: Contacts who have marked your emails as spam.
  • Unengaged new subscribers: Recent sign-ups who haven’t interacted with your emails after joining.
  • Duplicate entries: Multiple entries for the same person or email address.
Regular email scrubbing helps you focus on the people who are truly interested in your content. By cleaning your list, you can – improve your email deliverability, make sure your messages reach the right audience, and get better results from your email campaigns.
Why Email Scrubbing is Essential?

Did you know? The average email open rate across all industries is 21.33%. By following email scrubbing – you can increase the rate.
Email scrubbing might feel like losing the subscribers you've worked hard to gain - but if those contacts aren’t engaging - they’re only boosting your numbers without adding real value. Regularly email scrubbing is important, and here’s why:
  • Improves Deliverability
Removing inactive and invalid contacts reduces the chances of your emails bouncing or being marked as spam. This increases the likelihood that your emails will reach the intended recipients' inboxes, helping your messages get seen by more of your active subscribers.
  • Accurate Engagement Metrics
If your list is full of inactive subscribers - your open rates and click-through rates (CTR) will appear lower than they actually are. Removing inactive contacts helps you get a more accurate picture of your campaign’s success. In fact, after cleaning their list - companies often see improved engagement rates.
  • Lower Bounce Rates
Email bounces occur when messages fail to reach the intended recipient due to invalid addresses or full inboxes. Regularly email scrubbing reduces the number of bounces, protecting your sender reputation.
  • Fewer Spam Complaints
Some subscribers might mark your emails as spam simply because they forgot they signed up. Too many spam complaints can lead email providers to send all your emails to the spam folder. By removing uninterested contacts regularly, you reduce the chances of this happening.
  • Better Sender Reputation
A clean email list improves your overall email performance, leading to a better sender reputation. A strong sender reputation means more of your emails will land in the inbox rather than the spam folder.
  • Boosts Engagement
Focusing on active subscribers means your emails are more likely to be opened and clicked. This improves key metrics like open rates and click-through rates, showing better engagement with your audience and making your email campaigns more effective.
  • Reduces Costs
By using email scrubbing, you send fewer emails, which can lower your costs with email marketing services. This way, you’re only paying for subscribers who are engaged and likely to respond, making your marketing budget more efficient.
  • Increases ROI
With a cleaner list, your email campaigns are more effective because they target engaged subscribers. This leads to better results, such as higher conversion rates, which ultimately boosts your return on investment (ROI) from email marketing.

Email scrubbing is essential to keep it healthy and effective. But when should you do it? Here are some key times for email scrubbing:
  • Regularly, Every Few Months
It's good practice to follow email scrubbing every 3 to 6 months. This helps remove inactive or invalid contacts before they start affecting your engagement and deliverability rates.
  • After a Major Campaign
If you’ve just finished a big email campaign, it’s a perfect time for email scrubbing. You can identify who engaged with your emails and who didn’t, helping you remove those who are no longer interested.
  • When You Notice a Drop in Engagement
If your open rates or click-through rates start to drop, it might be time for email scrubbing. A decline in engagement often means there are inactive subscribers who need to be removed.
  • When You Experience High Bounce Rates
A spike in bounce rates, where emails are not delivered, indicates that some email addresses on your list may no longer be valid. Email scrubbing helps eliminate these bounces, improving your sender reputation.
  • Before a Big Marketing Push
If you’re planning a major marketing campaign or a product launch, clean your list first. This guarantees you’re reaching out to the most interested and active contacts, maximizing the impact of your campaign.

Note
Make sure your email list is saved in a file format, preferably CSV. If your list is in your mailing system - you'll need to export it first and save it to your computer.
Step 2: Eliminate Duplicate Entries
If your email system doesn’t automatically manage duplicates - you’ll need to handle this manually. Start by exporting all your email lists into a CSV file. Open the CSV file in Microsoft Excel or another spreadsheet application.
Use the “Data” menu to select “Remove Duplicates.” This function will find and delete any duplicate entries, guaranteeing each contact appears only once on your list. This helps maintain a clean and efficient email list.
Step 3: Clear Out Unsubscribed Emails
Most email service providers (ESPs) offer tools to manage unsubscribed contacts. These contacts have opted out of receiving your emails and should be removed to avoid sending unwanted messages.
Within your ESP - locate the section where unsubscribed contacts are listed. You can then choose to delete or archive these contacts. Archiving might be useful if you want to keep records for future reference - but deleting them keeps your list current and clean.
Step 4: Remove Spam Complaints
Check your ESP’s reports to identify anyone who has marked your emails as spam. These complaints can harm your sender reputation and affect email deliverability. Access the spam complaint reports, locate the offending addresses, and remove them from your list.
You can do this manually by reviewing reports or use automated tools that can streamline the process. Regularly removing these contacts helps maintain a positive sender reputation and improves your email delivery rates.
Step 5: Reengage Less Active Subscribers
Before removing inactive subscribers - send a re-engagement email. Divide your subscribers into categories based on their engagement level –
  • Gold (highly engaged)
  • Silver (somewhat engaged)
  • Bronze (least engaged)
For those in the Silver and Bronze categories - send a series of re-engagement emails with enticing offers or new content to try and win them back.
If they don’t respond after several attempts, consider removing them from your list. This approach helps focus your efforts on subscribers who are most likely to interact with your emails.
Step 6: Remove Inactive Contacts
Review the activity history of subscribers who haven’t engaged with your emails for a long period. If they haven’t opened or clicked on any emails recently, it might be time to remove them.
However, if these contacts have previously made purchases but haven’t opted in for email updates, send them an opt-in request. If they remain unresponsive, remove them to keep your list focused on active subscribers.
Step 7: Regularly Repeat the Process
Email list scrubbing isn’t a one-time task. To keep your list healthy and your campaigns effective, repeat the scrubbing process every few months. Regular maintenance helps you stay on top of inactive contacts and ensures your list remains clean and engaged.
