Write Better Emails in a Fraction of the Time

AI drafts emails matching your style and tone. You review, refine, and approve before anything sends — combining AI speed with human judgment.


Why this matters

Writing professional emails consumes significant time, especially for difficult conversations, non-native language composition, or nuanced negotiations. Many professionals spend an hour or more daily composing and editing emails, time that could be better spent on strategic work.


How MultiMail solves this

MultiMail's AI agent composes email drafts based on natural language instructions, maintaining your writing style and adjusting tone for each context. With gated_send oversight, you review and refine every draft before delivery, keeping the human judgment that matters while offloading the writing effort.

1

Give Instructions

Tell your AI agent what you want to say, the tone to use, and any key points to include. Natural language instructions work: 'Reply to Marcus saying we're interested but need to see pricing first. Keep it professional but warm.'

2

AI Drafts the Email

The agent composes a draft using send_email or reply_email, matching your writing style learned from previous emails. It handles structure, tone, and formatting.

3

Review and Refine

With gated_send, the draft enters your approval queue. Read it, make edits, adjust tone, or add details the AI missed.

4

Send with Confidence

Approve the final version and it sends immediately. Track sent emails and thread replies for ongoing conversation management.


Try it with your agent

Pick your platform, copy the prompt, and paste it to your AI agent — it sets up MultiMail and builds the whole flow. Nothing to fill in.

1. Read https://multimail.dev/llms.txt, connect the MultiMail MCP server, create a free inbox, and set up a verified sender. 2. Connect to my Google Workspace Gmail account with OAuth, use the Gmail API to watch for new messages and label changes, and treat any message labeled “AI draft” or any draft request I place in Gmail as a trigger. 3. For each trigger, read the thread, infer the recipient, relationship, goal, constraints, and needed tone, then compose a concise professional reply or new email in my usual style; for difficult conversations, include a clear subject, direct opening, neutral language, and a specific next step. 4. Use MultiMail to compose and schedule or send the email only in gated_send mode, so every draft waits for my review before delivery. 5. To go live, ask me only for Google Workspace authorization, my preferred sending domain details, and a short brand or writing-style sample.

Common questions

How does the AI learn my writing style?
You provide style examples and preferences to your AI agent — formal vs. casual, short vs. detailed, specific phrases you like. The agent also improves from your edits: when you modify a draft before approving, those changes inform future drafts.
Can I use different tones for different recipients?
Yes. Your AI agent adapts tone based on context and instructions. You might request a formal tone for client emails, casual for team communications, and diplomatic for negotiations. Recipient metadata in contacts can store tone preferences.
What about emails with sensitive content?
Gated send ensures you review every draft before delivery. For particularly sensitive emails — negotiations, HR matters, legal communications — you have full control to edit, rewrite, or reject the AI draft entirely.
Can the AI draft emails in multiple languages?
Yes. Modern AI models can compose fluent emails in dozens of languages. The AI drafts in your specified language while you review for accuracy. This is especially valuable for bilingual professionals managing communications across language boundaries.
