Emmie, Sintra's AI email assistant, writes the cover note that goes with your attachment: tell her what you are sending and to whom, and she drafts the subject line, a line naming the file, a short explanation, and a sign-off.

What can Emmie do for your attached file email?
Emmie is one of Sintra's AI employees built for professional correspondence, and she covers every common document-sending situation. Here is what she does.
Write the message that goes with the file. Give Emmie the document and the recipient, and she drafts a clear cover note, the "what to write in an email when sending documents" part that causes the blank-screen moment.
Name the attachment clearly. Emmie references the attached file by name and type in the body, so the recipient knows exactly what is included before they scroll.
Match the formality. Sending a résumé to a recruiter is not the same as sending a report to your team. Emmie writes the note at the register you ask for.
Get the subject line right. A subject like "Signed contract attached (PDF)" beats "Documents." Emmie drafts a subject that names the attachment and the action.
Keep it grounded in context. Feed the recipient, your role, and what the document is into Brain AI, and Emmie writes a note that fits the situation instead of a generic template.
Setting up Emmie to write attachment emails
Four quick steps, and the context you give upfront is what makes the note feel specific rather than generic.
- Sign up and open Emmie. Create your Sintra account and select Emmie from the Helpers list.
- Set up Brain AI. Add your name, role, and how you usually communicate to Brain AI. Paste or upload this directly in the chat, since Emmie cannot pull files from Google Drive.
- Share the context for this email. What document you are sending, its file type, who it is going to, and how formal the note should be.
- Ask Emmie for the cover note, then attach the file in your own email client and send it yourself. Emmie writes the message; the attaching and sending are on you.

How to write an email with an attachment file with AI in 5 steps
Each step is a common document-sending scenario. Run them in order to see the range, or jump to the one you need right now. In every case, Emmie writes the message and you attach the actual file before sending.
Step 1: Write a professional email for sending a document
The standard situation: a document needs to go out with a clear, professional cover note that tells the recipient what they are receiving and why.
Prompt: Emmie, write a professional email to [recipient] to send them [document name], a [file type] about [topic]. Mention the attached file, explain what it is in one line, and ask them to [action]. Keep it clear and polite.
Output: A complete cover note with a subject line, greeting, a line naming the attached file, a short explanation, and a sign-off. Attach the document in your email client, review the note, and send.
Step 2: Write an email sending your résumé or CV
Application emails need to do two things: make a brief case and point clearly to the attached file. Emmie handles both in a format that is ready for a recruiter to open.
Prompt: Emmie, write an email to [recruiter/hiring manager] applying for [role] at [company]. My résumé is attached as a PDF. Briefly say why I'm a strong fit and point to the attached file.
Output: A short application email that references your attached résumé and makes the case in two or three sentences. Attach the PDF yourself, check the details, and send.
Step 3: Write an email sending a report or invoice
Reports and invoices need a cover note that names the mail attachment, summarizes it, and flags any action or deadline without burying the reader in repetition.
Prompt: Emmie, write an email to [recipient] sending [report/invoice name] as an attached [file type]. Summarize what's inside in one or two lines and note any deadline or action needed.
Output: A tidy cover note that names the attachment, summarizes it, and flags the next step. Attach the file, confirm the numbers and dates, and send from your account.
Step 4: Write a short note for multiple attached files
When several files go out together, a clear list in the message body stops the recipient from guessing what is what. Emmie structures it so each file is accounted for.
Prompt: Emmie, write an email to [recipient] sending [number] attached files: [list them]. Briefly say what each one is so nothing gets missed.
Output: A clear message that lists each attached file and what it contains. Attach all the files yourself, check the list matches, and send.
Step 5: Follow up on a document you already sent
When an attachment sample email for sending documents got no reply, the follow-up needs to reference the original without sounding pushy. Emmie keeps it short and in the same thread.
Prompt: Emmie, I sent [recipient] [document] [X days] ago and haven't heard back. Write a polite follow-up that references the attached file from my earlier email and asks about next steps.
Output: A low-pressure follow-up that points back to the document you sent. Send it in the original thread so the attachment stays in context.
Writing an attachment email manually vs. with Emmie
A note on quality: Emmie writes a strong cover note, fast, but she doesn't see or attach the actual file. Always attach the correct document yourself, confirm it is the right version, and read the note before sending. The draft is the starting line, not the finish.
Tips for writing better emails when sending documents
These are the habits we lean on to make attachment emails clear and professional every time.
Always mention the attachment in the body. Don't leave the file to speak for itself. Ask Emmie to name the attached file and say what it is, so the recipient knows before they scroll.
Put the file in the subject line. "Q3 report attached (PDF)" tells the reader everything up front. Let Emmie draft a subject that names the attachment and the action.
Explain the file in one line. A single sentence on what the document is and why you're sending it saves the recipient a guess. Give Emmie that context so the note lands.
Attach the file first. Attach the document before you write the note, or at least before you send, so you never fire off an email promising a mail attachment that isn't there. Emmie writes the note; the attaching is yours.
Check the version. Emmie cannot see your file, so confirm you attached the final, correct one. Double-check the file name and type before sending.
Keep the cover note short. The document does the heavy lifting. Ask Emmie for a brief, clear note that points to the attached file and gets out of the way.
