I like Addy as it allows to create mail aliases which relay to your real mail. So you cen delete the alias as soon as it gets spammed.
If the free tier of the website is to restrictive for your uses, Addy is hosted by other FOSS supporting platforms and their limits vary.
Which brings me to boil is that they use 'pardner'.
I'm not your pardner in any way. I just wanted to read an aswer in my search results for a quite specific question.
Every time I read this 'whoa there, pardner' I want to scream at my screen that they should shut the fuck up.
