How does list cleaning work?


A high number of bounces can hurt the deliverability of your emails. It's generally a good practice to run some kind of email verification tool on your list to help weed out bad email addresses. While running your list through an email verification tool does significantly reduce the total number of bounces it doesn't guarantee you'll see 0 bounces. 

How Mailshake's list-cleaning works

After uploading a list of recipients, Mailshake will ask you if you'd like to clean your list. It will show you how many list-cleaning credits your team has and prompt you for payment if you need more to clean this list:

The cleaning process can take up to 15 minutes to run, so Mailshake will run it in the background while you continue setting up your campaign:

Once list-cleaning is finished, the results will pop up for you to review. You can download the results to a CSV file for further review and you can remove risky and/or bad email addresses from your campaign. A "risky" email address is one that has a higher-than-normal risk of bouncing, but it's hard to say for sure if there's a problem. A "bad" email address is almost certain to bounce.

How pricing works

Every team gets 500 free list-cleaning credits upon signup. 1 credit means you can run email verification on 1 address. After that, you can purchase 5,000 credits at a time for $10. 

Here's an example:

  • Your team gets 500 free credits at signup
  • You upload a list of 2,000 recipients
  • Your team will be asked to pay $10 to buy 5,000 credits (since you don't have enough to cover 2,000 recipients)
  • Your 500 free credits will be used up, as will 1,500 of your purchased credits
  • Your team will have 3,500 credits left

Here are answers to some common questions:

  • Purchases of credits are non-refundable
  • Credits don't expire and anyone on your team can use leftover credits
  • Running the list cleaner does NOT guarantee you won't see any bounces.
