Unfortunately, no. All sales are final and we don't provide refunds.
What happens with the remaining credits on my account?
The credits never expire and you can use them whenever you want. If you buy more credits, it will be added to your current credits balance.
How many credits I will need to clean my list?
You will need, at least, the same number of the total of the emails in your list. Examples: if your list has 1900 emails, you must buy 2000 credits. If your list has 55000 emails, you must buy 100000 credits at once, or you can buy 50000 then come back and buy 5000 more.
