I built Maskmail because I was tired of handing out my real email to every app, store, and newsletter. One bad signup and my inbox was flooded. I wanted per-service isolation without switching email providers. Maskmail is the tool I wanted but could not find. I am my own first customer.

this is the kind of tool I didn't know I needed until I saw it. I've been giving out my real email like candy for years and now I'm drowning in marketing garbage from companies I bought one thing from in 2019

Just signed up. Creating a mask took like 3 seconds, already used it for a sketchy newsletter signup lol. Kill switch is satisfying to use.

I created a Free wellness toolkit for burnout, anxiety, ADHD and overwhelm. 12 tools. No login. No data. No payment. Just open it and use it. lumacare.app

Strong positioning. One concrete before-and-after workflow on the page would make the privacy benefit land even faster for buyers.

Clear value and solid positioning, but it’s too long and loses impact without tighter hierarchy and a stronger primary CTA.
Really useful concept — protecting your real email while still receiving everything is underrated. I'd love to see a feature that lets you categorize masks by purpose (shopping, newsletters, signups). Would make it even more powerful for inbox management.
The per-service isolation model here is exactly the right mental model for email hygiene. Most people give out one email everywhere and then have no way to identify which service sold their data — with Maskmail, the mask itself tells you who leaked it. The anonymous two-way reply feature is the detail that makes this actually usable vs. just a one-way throwaway address. Catch-all support + custom domains makes it enterprise-credible too. Would love to see bulk mask creation for power users who are migrating off an old email address.
This is interesting!

yes it does!
Looks like promising. It's like tempmail but for different use case!
Growth and operations at RouterBase, an AI API gateway giving developers unified access to 200+ models through one OpenAI-compatible endpoint.
The idea of an "email mask firewall" really resonates, especially the instant kill switch. I've been using something similar, <a href="https://routerbase.com">RouterBase: One API for GPT</a>, for managing API keys, and the control it offers over individual access points feels very much in the same vein of security and convenience.
