Roll back changes of data value

[Anonymous]

Yesterday I changed values in 1 field across almost a bunch of leads. I needed to add something so I did it this way:
Attribute: Email Preference
New Value: {{lead.Email Preference}}; Blog

Well, now I want to remove what I added from there. Do you think I could somehow roll back the entire campaign or deduct "Blog" in batch? Looks like adding is much easier than taking away...

Ye, it's trickier.

Are the values a list of values or is it open text?

Let's take your example, I think that  the field now has "Email Preference,; Blog" and you want to remove Email Preference?

You can use the filter Data value changes and add the previous value constraint
Data Value Changed
Attribute : Name of the field
Date of activity : yesterday's date
Previous Value : is Blog

Flow
Change Data Value to Blog

The down side is that you would have to run an individual campaign for each value.

It might be easier to export all updates leads and remove the first value in your speadsheet and then re-import?

Cathal's got good suggestion there. I had to do something similar with a list import where I thankfully had the Old Score values logged in SFDC.
 

Another way to do this, if it is simple is say

Smart List:
Member of Campaign IS X
If Email Preference = Blog

Flow:
Change Data Value Email Preference = XXXX

check the counts to make sure that matches up with what you did.

Thanks a lot, guys! I´ll try to do as Cathal says, it will take time but at least it´s doable 🙂
