Why is there no invite button.
With all the chaos going on stateside my father, brother, and best friend are interested in leaving all the big tech companies they can. I wanted to invite them to ProtonMail but couldn't find a simple invite button. Yeah, it's not necessary, but it's something simple and I'm surprised it's not there. Unless I just couldn't find it... that's would be a design issue.

A related idea would be a reference program. I don't know... 100MB per reference? I've got three people to reference right now.

I would like to be able to send a referral link to friends to promote Proton Mail

Extremely missing this function, however it would be a win-win-win:
- i dont have to explain my friends / family members what is it how to register
- one click action for friends
- better growht for protonmail

I want to refer other people to ProtonMail. Where do I do this. It should be prominent in the email window

definitely would help to encourage friends to join the service.

I can't justify yet to pay for my inbox when so many free available, but among all I prefer secure ProtonMail.
However, it would be nice if by promoting ProtonMail we could get some features unlocked or storage added.

This is a great idea, I'd wish it is possible like now.

An excellent idea. A credit of 1 to 3 months depending on the signup account level.

Set up a referral system with link to forward. Offer a free month for those who refers new business and for the one who signs up or something to that degree.

Is this possible?

Agreed! Make the proton signature a referral link to benefit both parties.

Why don't we get a discount when we bring you new customers?
Very discouraging to invite people outside our "inner" circles...
