We had a webinar list for upload to Marketo, however once uploaded the Address field got overwritten with wrong values. Is there a way to get the past data of Address field which got overwritten due to upload.
Thanks & Regards,
The past data will be present in the Activity Log, which can be extracted via API and re-merged if you have a developer.
If you don't have a dev there's a service somebody built for exactly this purpose that I can recommend.
I am a happy Digital Pi client, and Jep has presented at my MUG and is a very smart guy, but I haven't used either service specifically. I would imagine that each service can only undo data that's been overwritten within the past 90 days due to Marketo's data retention policy.
