How do I delete those who have not opened an email in the last two years but exclude those who have just subscribed--say in the last three months?Â
 Cleaning your email list
Hello @CIFMarketing0296 ,
You'll want to follow this process:
Segment your contacts with the criteria of Email Activity > Not Opened > Any Email > In the Last > (choose time frame)
Add the segment to a brand new list (recommend just calling it Delete List or DNO List).
Sort your contacts based on Date Added. If Data Added isn't one of your options, edit the visible columns, and switch one of the default columns to that. Then click the Date Added column until they're sorting by most recent additions.
Select all contacts that have been recently added. I generally recommend up to 3 months back, but it will largely depend on how often you send your emails. For example, daily senders may want to only go back a month, whereas quarterly senders may want to save everyone up to a year.
Once you've selected all the recent additions you wish to keep, remove them from the Delete/DNO list.
Once the recent additions are removed from your Delete / DNO list, click the top checkmark box to select everyone left, then delete them. Deleting the contacts by selecting them all will ensure they are truly deleted from your account's contact database, removing them from other lists they're in as well.
