It is not clear to make what the difference between the two is, is Marketing Cloud Engagement for Nonprofit a subset of the regular Marketing Cloud? is it like Pardot? is a completely different product? if that is the case, is it in-platform? Would it work in the new Nonprofit Cloud? Thank you all
"Marketing Cloud Engagement for Nonprofits" is a special tier built with the idea of giving smaller nonprofits access to Marketing Cloud (NOT Pardot). It covers core bits like the integration with Salesforcce and Email Builder, but no Journey Builder.
I recommend chatting through your plans, goals, and needs for an email solution as a starting place. As much as the "Marketing Cloud Engagement for Nonprofits" is lower than regular price, it's still pretty high compared to other tools/nonprofit rates on the market, especially for not including Journey Builder. Marketing Cloud proper (not Pardot) is also a fair bit more technical, and you'll need to either skill up internally or bring on support services to fully take advantage of its functionality.
Marketing Cloud Account Engagement (FKA Pardot) on the other hand, is priced a bit higher but tends to be more popular with nonprofits in my experience as it has more automation included and it's much more user friendly
