I give my preference to using these two services - [Mail3](https://mail3.me) and [EtherMail](https://ethermail.io). They are built on Web 3 technologies and perfectly cope with spam and phishing attacks, have an increase level of security and privacy compared to traditional email service providers.

Hello! Thanks for your question. It's not a Web3 platform, but I would recommend using ProtonMail for a secure end-to-end email service. ProtonMail offers end-to-end encryption, which means that only the sender and recipient can read the content of the email. Additionally, ProtonMail stores all user data in a secure data center in Switzerland with strict data privacy laws. I hope this helps!
