Using Thunderbird’s Email, Calendar and Contacts

The primary areas you’ll spend time in Thunderbird include Email, Calendar, and Contacts accessed via the customizable sidebar or top navigation icons.


Viewing, reading, managing and searching email can be done efficiently thanks to keyboard shortcuts, tabbed inbox viewing, and custom folder organization. You can customize the appearance of the reading pane and choose to view email messages by date, sender, topic threads and more.

Spam management is aided by Bayesian filtering which learns what you consider spam over time for better future filtering. Search quickly pinpoints emails and attachments with relevancy based results and advanced search operators.


When it comes to managing appointments and events, Thunderbird features a built-in calendar which supports calendar server compatibility with Google Calendar, iCloud, Outlook, Facebook events and more (with add-ons installed). You can share your calendar availability with others publically while also syncing events across devices.

The Lightning Calendar add-on enhances functionality further. From a calendar overview by day to managing tasks, events and multi-day trips, Thunderbird keeps all your important dates in order.


Thunderbird’s address book stores all your contacts locally in a searchable database or can optionally sync contacts to external providers if you still want access outside of Thunderbird. Simply drag contacts or contact groups from Thunderbird into email messages to quickly address messages rather than manually typing emails.

So whether you need to email people, schedule meetings or find contact info, Thunderbird consolidates these key communication features into one convenient app.

Now let’s talk privacy protection…

Security Features and Protocols

For people taking email privacy and security seriously in a Post-Snowden era, Download free Thunderbird checks the boxes across the board including:

  • Encrypted Login Support: Thunderbird allows connections to email servers using TLS encryption for secure transmission of emails.

  • PGP/GPG Encryption: Through Enigmail add-on, you can leverage OpenPGP standards to encrypt email content and digitally sign messages validating sender authenticity.

  • Two-Factor Authentication: Enable an extra layer of protection by requiring a verification code from another device when accessing email accounts.

  • Master Password: Create one master password to lockdown Thunderbird requiring authentication before accessing any private data.

  • Remote Content Blocking: Block remote content like images to prevent sender spying and maintain privacy.

So if you want maximum email and messaging security along with convenience, Thunderbird Activation key is tough to beat – and that’s before considering it costs nothing as an open source app!
