A lot of important work still happens over email: sales, support, hiring, fundraising and the messages in between. This AI email generator turns a short brief into a polite, professional draft with a clear structure and purpose. Describe who you are writing to, what has happened and what you need from them, then choose a tone and a length. You get up to three suggestions to compare, copy and edit. Generating requires a signed-in Social media studio account, and each generation uses AI caption credits from your plan or trial.
When AI email drafting helps, and when it doesn't
AI is most useful for the emails you put off: a tough piece of feedback, a reply to an upset customer, a request for budget, an introduction between two busy people. Most of the effort in these goes into structure and wording, and a draft gives you something to react to instead of a blank screen.
It helps less with quick, conversational replies. A two-line answer to a coworker usually reads better in your own words, and a polished AI version can feel oddly formal. Save the generator for messages with a clear goal, more than a few sentences or enough at stake that you want to compare a few versions before you send one.
How to write a brief that gets a usable draft
The brief is the only input, so everything the email needs has to be in it. Cover four things: who the recipient is and how you know them, what has happened so far, what you want them to do, and any facts that must appear, such as dates, prices, names and links. If you have a rough draft or the message you are replying to, paste it in. The brief holds up to 5,000 characters.
Be explicit about the kind of email. A brief like "Decline a vendor's proposal politely and keep the door open for next year" gives the AI far more to work with than "Write a rejection email." Vague briefs produce generic emails, and generic emails are the ones people skim and forget.
Common email types and the structure each needs
Meeting follow-up: thank them, recap the decision and confirm who does what by when.
Internal update: lead with the outcome, then what is blocked, then what happens next.
Support reply: acknowledge the problem, give the fix or a timeline and say what to do if it doesn't work.
Apology: name the mistake, take responsibility, explain the fix and stop. Long apologies sound defensive.
Decline: be kind, brief and clear, without false hope.
Request or pitch: the problem, your proposal and one specific ask.
Name the type and the structure you want in your brief. For cold outreach, follow-ups and subject lines, the "What would you like to write?" dropdown has dedicated tasks.
Choosing a tone and length
Tone and length sit in the optional settings. Tone defaults to Concise, which suits busy readers and quick requests. For most work email, Professional, Formal or Friendly are the natural picks. The other tones (Engaging, Humorous, Creative, Sarcastic, Inspirational, Witty and Optimistic) are there for lighter messages, so use them with care in anything a client or manager will read.
Length offers Short, Medium and Long. Start with Short for most emails: it is easier to add one missing detail than to cut a padded draft. Whatever you choose, read the result again before you send it. The AI only knows what your brief tells it, so check every name, date and number yourself.
