Is there a limit to the number of records we can upload to a contact list? | XM Community
Skip to main content

I've successfully uploaded a large contact list (~115,000 records) multiple times. It works, and I see that there are ~115,000 contacts in my list. I then go back in later, and it only shows that I have 65,000 records in the list. Every record over #65,000 was automatically dropped. And now we've got alums trying to login but can't because their record is one that was dropped.
Is this a limitation to my file type (i.e. the old Excel file size limitation of 65,000 rows)? I used a CSV, so I wouldn't think that was it. Or is there something in our account license preventing over 65,000 contacts in a single list? We have other contact lists, so in total, we have over 65,000 contacts. I just don't get why it would successfully complete the upload but then drop half of my contacts (with no notification or error).

dmccoyny - Not sure whether we have a limit to the number of contacts in a mailing list, but it is surely more than 65K. I have had contacts lists with 200K contacts.

This could be something on your license or the file that you are uploading has duplicates(which seems very unlikely).


I reviewed our account and didn't see any restrictions. I also checked my file, and no dupes present. However, I was able to amend our contact list by importing the remainder of the file (that was dropped), and so far the record count is holding. So I haven't yet found a reason for why the records dropped, but I at least have a working band-aid. But since I don't yet have an explanation as to what happened, I'm going to have to monitor the next file I upload daily for dropped records. Obviously that's frustrating.


Logged in this morning, and it shows that I accepted the first response as the answer to my question. I did not. And I'm not sure who did on my behalf.
