Adding email to an existing NPS survey

Hi there!

We have an existing in-app only NPS campaign that has equal distribution every 90 days. I'd like to edit the NPS guide to include email distribution as well as in-app surveys. Is it as easy as editing that part and saving it? Are there any pitfalls/aftereffects I should be aware of? Seems pretty simple, but figured it was best to check before I made the change. Thanks!
