EtherMail’s Web3 Email Model Reaches 2 Million Users With Wallet-Based Identity

EtherMail’s pitch starts with a familiar inbox problem: messages from long-forgotten subscriptions and marketing lists can crowd out the communications people actually want. Its answer is to make senders earn access, while tying an account to a crypto wallet rather than a conventional username. The company says it has passed 2 million users, with demand coming largely from Web3 communities that want to communicate without connecting wallet activity to a person’s everyday identity.

That approach comes with trade-offs. Wallet-based access can reduce reliance on personally identifying account details, and sender controls give users more say over incoming mail. But EtherMail’s privacy and encryption claims are the company’s own description of its system; the interview doesn’t provide technical documentation, independent security assessments, or details about the cryptographic design. For teams evaluating it, those specifics matter as much as the product’s user count.

Wallets replace conventional email identities

Shant Kevonian, EtherMail’s co-founder and CEO, describes the core difference from services such as Gmail and Hotmail as identity. Traditional providers commonly associate an email address with a username and password. EtherMail instead links an account to a wallet address and uses the wallet’s signature to establish ownership.

That setup can support pseudonymous use: a wallet address doesn’t inherently reveal a user’s name, provided the user hasn’t connected it to identifying information elsewhere. It also keeps account access within a Web3 wallet workflow, rather than depending on a password that a user might forget. The privacy benefit therefore depends partly on how a person manages and shares their wallet address. A public address can still become identifiable through its activity or through information associated with it outside EtherMail.

Kevonian says EtherMail encrypts emails and that the company doesn’t retain a trace of the linked information on its servers. The interview offers no implementation details about what data is encrypted, where encryption and decryption happen, or how metadata is handled. Those distinctions are important: message contents, sender and recipient details, and account activity can have different protections. The article’s broad description should be read as a product claim, not as a complete security specification.

The idea grew out of NFT work

Kevonian says the concept took shape while he and co-founder Gerald Heydenreich were working with non-fungible tokens. He wondered whether people using Web3 could also have an email address suited to that environment. The founders discussed the idea for roughly two years before building it, waiting until they felt the market and community were ready.

Their premise was that email already had useful decentralized qualities: people can retain access to their accounts and data across different services. EtherMail’s goal is to carry that familiar communication format into Web3, where wallet addresses are already used to identify accounts and where users may want to keep online identities separate.

Kevonian’s career includes a decade as a chief technology officer, during which he developed proprietary algorithms for several startups. He also served as a senior technical adviser to SoundStage.fm, an interactive virtual concert platform later acquired by Audius in 2022.

Privacy depends on more than message encryption

The interview compares EtherMail with Proton and Telegram, but the useful distinction is between message encryption, metadata access, and account identity. Kevonian says Telegram messages aren’t always encrypted and that its secret chats are a separate mode. He describes Proton as encrypted while raising questions about access to email metadata. These comparisons are his characterization; the interview doesn’t independently examine either service’s current architecture.

For EtherMail, Kevonian argues that wallet-linked accounts and the company’s claimed lack of stored user information leave it with little information to disclose. Yet a wallet address is itself a persistent identifier. If users reuse an address, or if public blockchain activity connects it to other accounts, pseudonymity may weaken. Evaluators should look for a clear explanation of what EtherMail stores, how it handles metadata, and what happens when users need account recovery or report abuse.

The wallet model also changes the recovery experience. Signing with a wallet can remove the need for a separate email password, but access then depends on the wallet and its recovery process. For users already managing crypto wallets, that may fit established habits. For newcomers, it adds a prerequisite that conventional email providers don’t impose.

Sender controls turn the inbox into an opt-in channel

EtherMail’s other central feature targets unwanted mail. Conventional email generally lets a sender reach an address unless the recipient blocks or filters them. Kevonian says EtherMail reverses that default, allowing users to choose who can send messages.

The company calls one part of this system a “Paywall”: a sender can pay tokens as a kind of toll to get a message through. The interview doesn’t specify the token amount, how the payment is distributed, or whether users can set different rules for different senders. Those details will shape whether the mechanism works as a practical filter, especially for people who receive a high volume of legitimate messages.

Kevonian also distinguishes malicious spam from ordinary marketing that recipients simply stop reading. He argues that consent rules and subscription practices haven’t solved inbox clutter because traditional email lets almost anyone write to a user until that user takes action. EtherMail’s default-blocking model makes control more explicit, though it also asks users to manage access and decide when a paid message is worth receiving.

Why the company says it passed 2 million users

Kevonian attributes EtherMail’s growth to a need for communication within Web3. Companies working with NFTs may want to contact current holders, whose wallet addresses can be visible on a blockchain without directly identifying them. Users, in turn, may want to receive those messages while keeping their Web3 activity apart from their everyday online identity.

That fit helps explain the company’s appeal to crypto communities, but the reported figure alone doesn’t show how many users are active, how frequently they send or read email, or how many are individual users rather than accounts created through ecosystem activity. The interview provides no breakdown of retention, revenue, or adoption outside Web3.

For now, EtherMail looks most relevant to people and organizations already using wallets and seeking a communication channel built around them. Its longer-term reach will depend on whether wallet-based identity and sender-paid access feel useful to people who don’t already operate in Web3. The practical questions are clear: how the encryption works, what metadata remains visible, and whether the opt-in model can keep unwanted mail down without making everyday communication cumbersome.
