How to Auto-Draft Sales Follow-Up Emails with n8n + Claude (No Code)
An n8n workflow watches your CRM or a Google Sheet for leads overdue a follow-up, pulls each one's context, and has Claude write a personalized email in your tone. The draft lands in Gmail for a one-click send. You never face a blank page, and no lead slips through the cracks.
How to Auto-Draft Sales Follow-Up Emails with n8n + Claude (No Code)
An n8n workflow watches your CRM or a Google Sheet for leads overdue a follow-up, pulls each one's context, and has Claude write a personalized email in your tone. The draft lands in Gmail for a one-click send. You never face a blank page, and no lead slips through the cracks.
The money is in the follow-up
Most deals close on the second, third, or fourth touch, and the follow-up is exactly what busy people skip. "I'll circle back next week" quietly becomes never, and the lead goes cold. This **n8n + Claude** workflow makes the circle-back actually happen, automatically, in your own voice. Every morning you wake to a folder of personalized drafts instead of a guilty to-do item.
Meet your morning assistant
Picture a small **morning assistant** that runs before you're awake. It scans your lead list, spots everyone who's gone quiet, reads what you last discussed with each, and writes a tailored nudge. Four steps do the whole job: - A **schedule** wakes the workflow up each morning. - A **filter** finds leads untouched for, say, five days. - **Claude** drafts a personal follow-up for each one. - **Gmail** stashes them as drafts for your one-click send.
Start with a heartbeat
Add a **Schedule Trigger** set to run each weekday morning. This is the "who needs a nudge today?" heartbeat that turns follow-ups from a thing you remember into a thing that just happens. The cron below means 8am, Monday to Friday. Because it runs on a timer and touches several apps, this is an Intermediate build, not a chat prompt. ``` 0 8 * * 1-5 ```
Pull only the leads that are due
Add a **Google Sheets** node (*Get Rows*) pointing at your lead list, then a **Filter** node that keeps only rows where the last-contact date is over five days ago and the deal isn't closed. A plain Sheet with name, company, last-contact date, and notes is all you need to start, and you can swap it for HubSpot or Pipedrive later by changing this one node. Now you only ever work leads that genuinely need attention.
Let Claude write in your voice
Add the **Anthropic (Claude)** node. Because the filter returned several leads, n8n runs this **once per lead** automatically, like a mail-merge with a brain. The secret is feeding in the real context, so each email references the actual conversation instead of reading like a mass blast. ``` Write a short, warm sales follow-up in my voice. Friendly, not pushy, one clear call to action. Reference our last conversation specifically. My name: [your name], [your company]. Lead: {{ $json.name }} at {{ $json.company }}. Last conversation: {{ $json.notes }}. Days since last contact: {{ $json.days_since }}. Return just a subject line and the email body. ```
Drafts first, always
Add a **Gmail** node set to *Create Draft*, mapping the lead's email to the recipient and Claude's output to the subject and body. **Create Draft** is your safety rail: nothing sends until you've glanced at it and clicked. A human stays in the loop while you skip the blank-page slog, and that slog is exactly where the time goes when you write these by hand.
Go hands-off when you trust it
After a week of reading the drafts, you'll know whether the quality holds. When it does, switch the Gmail node from *Create Draft* to *Send*, and add a final step that **updates the last-contact date** in your sheet. That date update is what stops the same lead from getting nudged twice. Now the whole sequence runs itself, and you only step in for the replies.
Build it on one test lead
Spin up n8n and add the Schedule Trigger, then the Sheets and Filter nodes pointed at a sheet with a single test row. Wire the Claude node and a Gmail *Create Draft* node after it, run it once by hand, and open Gmail to watch your first personalized draft appear. Once it reads right, let the schedule take over.

FAQ
Will it send emails without me checking them first?
Not unless you want it to. The safe default is to create a Gmail draft, so you read and approve every message before it goes out. Once you trust the output, you can switch the final node from "create draft" to "send" for fully hands-off follow-ups.
Do I need a fancy CRM for this?
No. A Google Sheet with columns for name, company, last contact date, and a few notes works perfectly. The same workflow swaps cleanly to HubSpot, Pipedrive, or Airtable later by changing one node.
How does it personalize each email?
You pass the lead’s details, their name, company, what you last discussed, into the prompt. Claude writes around those specifics, so each follow-up references the real conversation instead of sounding like a template blast.
How much does it cost to run?
The n8n side is free to self-host. The only per-use cost is the Claude API call, which is typically a fraction of a cent per email. Following up with 100 leads costs less than a coffee.
