This does what it says on the tin: helps you draft professional emails by asking for purpose, recipient relationship, key points, and tone. You give it context like "follow-up with a vendor, keep it formal, mention the delivery delay," and it structures a proper email with subject line and body. From davila7's template collection that's picked up 27.7K GitHub stars. It's straightforward scaffolding for when you need to sound professional but don't want to overthink the format. Won't replace your judgment on what to say, but it'll save you from staring at a blank compose window.
