I've added a new multiple option to my subscriber list so that I can now separate the recipients and get them to choose between two newsletters - or both (using the preference center).
To start off though, I want to populate the field so that all current subscribers get both newsletters (and can unsubscribe from each separately). i.e. I want to set both parameters to "yes" in the new field.
Can I? Or do I have to export and reimport then list?
Any wise thoughts are welcome.
The best way to do it is as you mentioned, export it, populate the new field quickly in Excel or whichever spreadsheet program you are using, then re-import it.
Thanks Davida. I'll do that.
