Android Add-ons

Mail Merge by Alexander Bergmann

This add-on is very handy when you would like to bulk send personalised emails to all individuals on a specific mailing list or in a specific address book.

Send Later by Jonathan Kamens, Jonathan Perry-Houts

True "Send Later" functionality to schedule the time for sending an email.

Collector's Note An add-on not frequently used, is the Send Later add-on. But once in a while it is handy to have the ability to schedule the sending of emails. Specially in cases where you prefer email sending and delivery to be on a certain date and/or time in the future.

Quicktext by John Bieling

Quicktext is an extension for Thunderbird that lets you create templates that can be easily inserted into your own emails.

Collector's Note The Quicktext add-on is useful in the sense that it allows one to pre-define paragraphs, different email (document) sections and proforma letters using variables that is replaced by the address book information of the individual the email is intended for. Quicktext has a much better customization ability than the standard Thunderbird template function. It is easy to customize and individualise emails with the aid of the Quicktext add-on.

Signature Switch by Achim Seufert

Switch the signature on/off or choose a new one from your predefined set.

Collector's Note This Signature Switch add-on, allows you to create and save a number of different email signatures. When you tend to use emails as your primary source of communications, it implies that you often have to "sign" emails differently due to various email contexts. This add-on makes it easy to quickly select the signature that is relevant to or suitable for the email you are writing. Another, less known but very handy, feature of the Signature Switch add-on is to create email signatures files that contains data which can be randomly displayed just below your official signature. The latter function is handy when you wish to display random, e.g. quotes, at the bottom of your email.

Collector's Note With the Stationary add-on, you are able to predefine particular email layouts and themes for specific purposes, particular context, occasions and or events. The Stationary add-on allows you to select the "stationary" you would like to use when compiling an email (e.g. different stationary templates for different companies or departments for instance).

Check and Send by H.Ogi

Check the message contents and addresses before you send the message...

Collector's Note In the rushed, hustle and bustle of everyday life, it frequently happens that an email is compiled in a hurry and some important aspects, such as addressing the email correctly, gets overlooked. The Check and Send add-on, provide you with the opportunity to finally check and confirm important emails details, before finally sending the email. This add-on, at times, can be a bit annoying, but it is much less that the frustration that you experience when you send of an incorrectly addressed email containing sensitive content.

Auto Compress File by TrVTrV

Compressor for attachment files. All platforms are supported (Windows, Linux and Macintosh).

Collector's Note Sending large email attachments or files with a specific file extension, often result in delivery problems with that email. Specifically attached file sizes exceeding 5MB. The Auto Compress File add-on gives you, when sending an email with an attachment larger than 1MB, the option to either zip the file or share the file via a file sharing cloud services such as Dropbox. Quite a handy feature is that it "checks" files sizes and "warns" you when attachments exceeds a certain pre-set file size limit. To effectively send and use cloud sharing of larger files, the Dropbox for Filelink add-on should also be installed.

Afrikaans spell checker by Dwayne Bailey, Translate.org.za, others

Afrikaans spell checker for Mozilla Firefox and Thunderbird

Collector's Note Use the Afrikaans spell checker when you often compile emails in the Afrikaans language. This spell checking add-on is very handy to avoid unnecessary "slips of the keyboard" mistakes. It contains a comprehensive Afrikaans dictionary and a handy tool to have in one's email compiling toolbox. I have been using it for a quite a while now and have to admit that only on rare occasions, I need to add a word to the existing dictionary.

Address Close Button by 46emak

Adds a Address Close Button to mail compose window.

Collector's Note Cleaning address field is just a little bit easier with the Address Close Button add-on. Instead of selecting and then deleting recipients, with this add-on you only click on the x to accomplish the same task. The Close Address Button add-on merely saves you a few keystrokes. But when dealing with a lot of emails during a week, these little time savers tends to add up at the end of the day.

Subject Manager by TrVTrV

Manages subject of composed emails.

Collector's Note One of the major frustrating issues in receiving emails is the subject line that often is merely re: reply, some meaningless text or - worse - empty subject lines. Quite often subject lines are generic or standard in nature, when describing the context of an email. The Subject Manager add-on allows you to pre-define "standard" subject lines that you most often use, and which can easily be selected when required. The Subject Manager add-on and the Reject Button add-on, can be a useful combination for one's efforts to root out poorly constructed emails that wastes time and effort.
