Put under control **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** December 07, 2019 **What do you like best about Thunderbird?** Thunderbird allows you to keep all mailboxes under control, both regular and certified email (PEC), and thanks to extensions, it is possible to customize every single aspect and utility. The function via the importexporttools plugin is very useful for automatically exporting selected emails to a folder in PDF format, which is very useful for saving acceptance and delivery PECs. Furthermore, the export of messages in mbox works excellently, and it is easy to load backup messages and find old emails. Recommended for everyone! **What do you dislike about Thunderbird?** The installed version without plugins is too lacking in options: for example, text controls (highlighter, quick color change, etc.) are missing and PECs are not fully supported. Installing plugins solves everything, but it would be advisable to integrate these features directly into the base software. **Recommendations to others considering Thunderbird:** If you want flexible software, capable of saving mail without issues in future imports, Thunderbird is the right software. By searching among the endless available plugins, you can truly customize every aspect. **What problems is Thunderbird solving and how is that benefiting you?** Mass saving of emails in PDF is no longer a problem for me: the emails are converted into PDFs in sequence and saved in the specified folder with the same name as the email subject; just insert the email's identification code at the beginning of the subject and you will automatically have the ordered PDFs ready for archiving. ### 13.

Because Thunderbird shares the application management engine with Mozilla Firefox, it is possible to browse the internet and even install visual themes that we can also find available for Firefox. **What do you dislike about Thunderbird?** The application can be a little slow when you have emails from the same server, for example outlook, when we have 5 to 10 emails from this domain, the inbox check is very slow and sometimes it is possible that we are required for 2FA confirmations or by mail electronic as security measures, which is very annoying. **Recommendations to others considering Thunderbird:** I recommend this service especially for people who need to keep local copies of their emails to be able to view them even when they do not have access to the internet, this is very useful to export emails to other computers. Also, if we have several emails, we avoid having to access by inserting credentials every day for each email. **What problems is Thunderbird solving and how is that benefiting you?** As a user of this application it has been very useful because I can check all my emails in a very fast way, just by opening Thunderbird I receive notifications from all my emails regardless of the domain to which it belongs. The application is especially useful since it is not longer needed to access the domain website for login so i dont have to waste time by inserting mail and password for every mail. ## Thunderbird Discussions - [What is the use of Thunderbird software?](https://www.g2.com/discussions/what-is-the-use-of-thunderbird-software) - 1 comment, 1 upvote - [Has anyone managed to use the copy and paste function from excell?](https://www.g2.com/discussions/12306-has-anyone-managed-to-use-the-copy-and-paste-function-from-excell) - 2 comments, 1 upvote - [Has anyone managed to use the copy and paste function from excell?](https://www.g2.com/discussions/30110-has-anyone-managed-to-use-the-copy-and-paste-function-from-excell) - 1 comment - [View Thunderbird pricing details and edition comparison](https://www.g2.com/products/thunderbird/reviews?page=3&qs=pros-and-cons§ion=pricing&secure%5Bexpires_at%5D=2026-08-07+22%3A58%3A56+-0500&secure%5Bsession_id%5D=c95abc33-2fb5-4be0-86d8-a09bf8d7a09a&secure%5Btoken%5D=e91ff84c1fce82c41958d88ca0fee042ede15c4a5dcfd35e1284ceec5a1c4c4d&format=llm_user) ## Thunderbird Features **Additional Functionality** - Third-Party Integrations - To-Do List - @mentions - Single Sign On - File Management - Activity Dashboard - Drag & Drop - Alerts/Notifications - Prioritization - Access Controls/Permissions - Screen Sharing - Content Management - Brainstorming - AI Copilot - File Transfer - Calendar Management - Status Tracking - Real-Time Notifications - Version Control - Task Management - Activity Tracking - Real Time Editing - Communication Management - Chat/Messaging - Tagging - Generative AI - Assignment Management - Task Scheduling - Project Management - Collaboration Tools - Workflow Management - Secure Data Storage - File Sharing - Document Storage - Task Progress Tracking - Discussions/Forums - Commenting/Notes - Reporting & Statistics - Contact Management - Video Conferencing - Progress Tracking - Mobile Access - API - Document Management - Customizable Branding **Inbox Tools** - Unified Inbox - Filters - Reminders - Notifications **Sorting & Filtering** - Attachment Search - Tags - AI Sorting - Predefined Rules **Coordination Tools** - Calendar - Contacts - Task Management **Integrations** - Microsoft Outlook Integration - Gmail Integration - Apple Calendar Integration - Social Media Integration - Third-Party Integrations **Software Options** - Desktop Application - Mobile Application **Time Management** - Unified Inbox - Email Automation - Snooze **Generative AI** - AI Text Generation - AI Text-to-Speech - AI Text Summarization - Generative AI **Email Client - Agentic AI** - Autonomous Task Execution - Cross-system Integration **Agentic AI - Email Management** - Autonomous Task Execution - Cross-system Integration **Additional Functionality** - Whitelisting/Blacklisting - Customizable Fields - Signature Management - Shared Inboxes - Email Distribution - Prioritization - Customizable Forms - AI Copilot - Mobile App - Routing - Activity Dashboard - Collaboration Tools - Inbox Management - Queue Management - Drag & Drop - Contact Management - Email Marketing - Data Recovery - Archiving & Retention - Real-Time Monitoring - Autoresponders - Multiple User Accounts - API - Real-Time Analytics - Customer Segmentation - Search/Filter - Support Ticket Management - Canned Responses - Workflow Management - Reporting/Analytics - Chat/Messaging - Response Management - Email Templates - Email Monitoring - Campaign Management - Email Tracking - Access Controls/Permissions - Spam Blocker - Alerts/Notifications - Customizable Templates - Real-Time Reporting - Tagging - Campaign Analytics - Workflow Automation ## Top Thunderbird Alternatives - [Front](https://www.g2.com/products/front/reviews) - 4.7/5.0 (2,450 reviews) - [Spike](https://www.g2.com/products/spike/reviews) - 4.6/5.0 (250 reviews) - [Mailbird](https://www.g2.com/products/mailbird/reviews) - 3.6/5.0 (100 reviews)
