What's the easiest way to edit an existing email waterfall model?
I created one, ran it for 10 rows, and now want to edit it to include more providers.
That's a very good question, we can't currently modify them but there may be something coming soon for that. The best workaround for now is to remove the old one and add a new one. cc Keethu R. for visibility :)
So yeah, removing the columns that you want to replace is the easiest/fastest way to achieve this change. Else, re-working the formulas could do it but it may get a bit messy or take some time to update them
