Envilope uses blockchain to create immutable records of what you send online, to who, and when. Ensure only its intended recipient can open your Envilope, and only under your customized terms and conditions.
So what is the difference these days? Any email records what I've sent on line and to whom. Not a blokchain of course, but better than nothing. What's the privilege of envelope?
The difference in more features and greater control. Better than nothing is not enough
For example, you can always delete and change the content sent by e-mail until the recipient has read it.
Well that's a realy good feature, may be something else you have in mind, but did not write it in the ANN?
