Well… answer is I didn’t know NTFY had a built in SMTP server. I just used this combo cuz before I used it to send my notifications to discord which mailrise makes easy. I will say that mailrise does let you more granulary define what e-mails will be sent to what topic while NTFY just uses the recieving address as the topic which might not be wanted.(I can for example define stetsed@* which means it doesn’t matter if I use one of my other domains, or father@* which means he could use whatever domain he would want).
So the only thing I will say is that the problem with a “DocuSign” alternative is that docusign is more accepted within the proffesional community and when docusign says something was signed it’s trusted. In this case what is to say you don’t modify the data or something similar, I know you could send out a confirmation e-mail or whatever but you get my point.
But ofcourse I will always take more apps that can be selfhosted :D
