Problem: Investors, Celebs, C-suite businessmen, Famous people, etc. are afraid to share their email id's publicly in fear of getting spammed.

Existing solutions: simplelogin by proton (aliases), hey (similar to simplelogin), hidemyemail by apple (only for signups and apple ecosystem), superdm (very trimmed down basic version for dm's, basically a glorified form), and some other basic extensions exist.

Idea: To build a complete layer of a tool which sits between the sender and receiver. Both sender and receiver don't change any habit. After the initial contact, they go back and forth in their existing emails. The tool acts as a gatekeeper.

Pros: Can stop emails before they reach inbox, can close emails access on off-days/vacations, or can accept emails for certain topics only. All they share is a public link of the tool, and in their dashboard can control how may emails they can get, by whom and at what time. Have full control of the incoming mails, without ever sharing their email.

Each conversation gets their own masked email, which the receiver can close whenever they want. If blocked, the sender mail can never respond nor create any new topic email.

Cons: You tell me!

I tried to explain the idea in very simple form. More stuff can be built on top of it.

Roast away the idea!

tl;dr: Share public link instead of actual email, respects privacy without changing any habit.
