# Formstr - **Website:** - **Primary alias:** `mailstr.app` ## Description Mail by Formstr is an email service designed around privacy and user-controlled access. Messages sent to an address ending in mailstr.app are encrypted to the recipient’s key and stored on relays the recipient chooses. Because the email is locked to that key, only the key holder can open the mail. Users sign in with their own key rather than relying on a separate account credential. To get started, users can choose a name and check whether the corresponding name@mailstr.app address is available. The service also supports bringing an existing npub. Access is offered with a one-time payment, according to the site. The product presents a simple inbox alongside its key-based email features, aiming to keep the experience focused on receiving and opening private messages. Mail by Formstr is part of the Formstr suite, which is presented as privacy-focused. Its core offering combines email addresses, encrypted message storage, user-selected relays, and sign-in with a personal key, giving users control over how their mail is protected and where it is stored. ## Industries - 🖥 Computers Electronics and Technology - 🖥 Email _(under Computers Electronics and Technology)_ ## Links - [github](https://github.com/formstr-hq) - [twitter](https://twitter.com/formstr) ## Logos & icons - logo _(primary)_ — PNG, SVG — [download](https://cdn.brandfetch.io/ids5W6jZJS/w/820/h/820/theme/dark/logo.png?c=1bxid64Mup7aczewSAYMX&t=1794103869407) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Cinnabar | #e5484d | accent | | Woodsmoke | #0b0b0c | dark | | Desert Storm | #f4f4f3 | light | ## Fonts - Inter — asset _(google)_ - Inter — asset _(google)_ - Inter — asset _(google)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
