its better to clean them manually for specific words in your CSV or EXCEL list.
Ctrl+F
keyword = Spam / Privacy / Abuse / Complaint / enquiry / enquiries / support / help / protect / group /
Find All - to check the number of emails contains this word
Then
1. Goto Conditional format
2. Select Highlight that contains "keyword" click to format the color
3. Sort > Custom sort > Sort by colors
All the highlighted emails will come to the top and remove them,
Repeat the process for all keywords.
P.S; sometime email contains subdomain e.g
[email protected] to remove these emails use in "contains" @*.*.com and it will highlight all emails.
it just took me 10minutes to clean a 100K list and remove 5000+ bad emails including spamtraps
