MailFollowUp 1.5 - Mac OS X Mail Add-On

MailFollowUp lets you create followup messages that have all the recipients of the original message and quote the original text easily in Mac OS X Mail.

Has the moment you clicked "Send" ever coincided with the moment you thought of another thing to write? Did you ever want to comment on something you received alongside a group of other people? Do you post regular updates to a flock of interested parties?

In each case, a group mail service is perfect, of course, and you could simply use the "Reply All" feature built into Mac OS X Mail. The latter suffers from a minor, though important, shortcoming, however. Replying to all creates a reply to the original sender, and all other recipients are transferred to the Cc: field. This makes some sense, but it runs against the idea of posting an addendum to a message in the same manner the original email was sent.

MailFollowup adds a "Followup" command to Mail that acts exactly like "Reply All", but keeps all the recipients in place. With MailFollowUp, you can follow up on any message you received or, in particularly useful a manner, sent with afterthoughts, comments and new material without confusing anybody as to whether your reply is intended only for the original sender.

MailFollowUp adds commands to menu and context menu as well as a keyboard shortcut. Of course, you can also add MailFollowUp buttons to your Mail toolbars, either stand-alone or in a "Reply - Reply All - Forward" combo. Additionally and deviating from the original idea, a command that creates a new message with all (but only) the recipients of an existing message could be great for instant group mailing.
