  • Opt-in inbox
    Only people you approve reach your inbox. Mail from senders you haven't approved goes to Trash, using patent-pending opt-in technology.
  • Passwordless sign-in
    OptMsg accounts have no password, so there is no password to steal. You sign in with a passkey.
  • Community Recommendations
    Point out trusted senders whose mail landed in your Trash, so you don't miss messages you want.
  • No Ads
    OptMsg does not scan your emails to sell ads, and we don't collect your personal data to sell to advertisers.
  • Built for personal email
    Designed for people and families, not businesses. Works on the web, iOS, and Android, with a free Reader plan to start.
  • Free and Open Source
    Thunderbird is completely free to use and its source code is open to the public, allowing for community-driven development and transparency.
  • Customization
    The application supports a variety of extensions and themes, enabling users to personalize their email client according to their preferences.
  • Cross-Platform
    Thunderbird is available on multiple operating systems including Windows, macOS, and Linux, providing flexibility for users on different platforms.

Possible disadvantages

  • Performance Issues
    Some users report that Thunderbird can become sluggish, particularly when handling large email archives or multiple accounts.
  • Less Intuitive UI
    The user interface can seem dated and may not be as intuitive or sleek compared to other modern email clients.
  • Limited Mobile Support
    Thunderbird does not have an official mobile app, causing inconvenience for users who need access to their emails on the go.
  • Dependency on Extensions
    While customization is a strength, relying on extensions for key features can sometimes lead to compatibility issues, especially after updates.
