Subjectivity is a software solution that prevents Mail.app users from sending emails without a subject line, reducing the likelihood of unintentional or incomplete communication.
If you do attempt to send a message without a subject line, Subjectivity will present you with a sheet of options to choose from. These options include using a suggested subject line, editing the message manually, or sending the e-mail as-is. If you select the suggested subject line option, the plugin will generate a subject line that lists attachment names (if any exist) or the beginning of the body.
Overall, Subjectivity is a reliable and incredibly convenient mailbundle plugin. It saves you from making simple mistakes that can have severe consequences, and it's effortless to use. If you're someone who uses Apple's Mail.app regularly, then Subjectivity is an excellent addition to your toolbox.
