Templates / AI Draft Replies for Every Gmail Email

AI Draft Replies for Every Gmail Email

Intermediate   Apps: Gmail, OpenAI  ·  Setup: 15 minutes

Most emails need a two-line answer you've written a hundred times before. Typing them still eats an hour a day. This workflow has AI pre-write a draft for every incoming email - in your tone, following your rules - and saves it as a Gmail draft. Nothing is ever sent without you: you stay the final filter.

What this workflow does

  1. A Gmail Trigger polls for new emails in your inbox.
  2. An AI node reads the sender, subject, and body, and writes a reply following your style instructions.
  3. A Gmail node saves the reply as a draft on the same thread - it never sends anything.
  4. You open the thread, tweak the draft if needed, and hit send.

Setup guide

  1. Import the JSON into n8n (Workflows > Import from File).
  2. Connect your Gmail account in both Gmail nodes.
  3. Edit the system prompt in the AI node: your name, sign-off, tone, and any standing rules (pricing answers, links you always share).
  4. Optionally narrow the trigger filter, e.g. exclude newsletters with '-category:promotions'.
  5. Activate, then email yourself from another address and check your drafts folder.

FAQ

Will it ever send an email by itself?No. The workflow only creates drafts. Sending always stays a human decision - that's the safety design.
How do I stop it drafting replies to newsletters and notifications?Tighten the Gmail Trigger filter, e.g. 'in:inbox -category:promotions -category:social -from:noreply'. You can also add an IF node that skips senders on a blocklist.
Can it answer in my writing style?Yes - paste two or three of your real replies into the system prompt as style examples. The drafts get noticeably closer to your voice.
