This week the weekly Engage Individual and Organization import file did not import and the error message was:
Error in line 8: ('White Mail' is not a valid option for field custom_20)
I just deleted the White Mail from all the rows as we don't use this option anyway and it imported. But I was concerned that it wouldn't import other Direct Mail options we use during our Appeal season e,g. Fundraising Mail etc. It looks like this is still an option when I checked the Direct Mail appeal options.
