Inquiry About Importing Unsubscribed Data to Salesforce Limitations

Hi Team. Question about the Import Report Data to Salesforce features... I have a report of Unsubscribed people in my SF - and I want to have that in a Clay table so I can do a lookup prior to adding to my email sender to ensure people are not getting unwanted emails. I see there is a limit of 2000 total records to be fetched for reports. Is that on per data pull or is it 2000 and no more. Curious as the report is more than 2000 rows long and will continue growing over time - so the limit becomes a problem for me.
