It's cheap i'm honestly just writing more to get to the minimum word count because I literally cannot think of anything else

Very little, honestly. The best features I'd argue is either the holding tank or the ability to store credit card information securely and then access later with future transactions. However, both of these features have HUGE issues. The holding tank (temporary contacts) forces you to either send the most boring, generic email receipt instantly OR your donors are waiting for their receipt until a user goes into your CRM and merges the temporary contact, which leads to confusion for donors, unsure if their gift went through. Also, the stored CC feature works great for one-time situation but can be flagged as fraudulent when doing recurring transactions so not ideal.

Works well, Integrates with salesforce. Easy to navigate and use. Protects donor info.
