This is a wonderfully simple mail addon. I have had the pleasure of helping to test it over the last few month. I have to say I have tried several other guild mailers and had issues with bugs. For any guild master or officer it is truly a Godsend.

Features include:

* Character count when composing mails (no more cut off mails)
* Compatible with hex codes for color coding titles and content.
* Ability to choose guild and rank from a simple drop down menu. You can use greater than/less than logic to send to multiple ranks as well.
* Sending of mail can be paused and resumed, allowing for opening menus and interacting with objects. The window can also be closed; the mail contents will remain until the mail is complete or until a reload UI is performed.
* Customizable to send mails to only those of specific rank within the guild
* Tracking of mails sent as they send
* Notice that mail has been successfully sent to individual recipients
* Notice when a recipient’s inbox is full
* Notice when an intended recipient has you on ignore, and mail cannot be sent
