Warm up Gmail inboxes with OpenAI GPT-4o-mini and Data Tables
UnknownUnknown. This template uses community nodes we can't verify statically. Uses community nodes that can't be verified statically (unverified community packages are off by default in 3.0). Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 45 nodes and runs on a schedule (every day at 06:00) (plus 3 other triggers). Along the way it connects OpenAI and Run Node With Credentials X (community).
How it runs
Trigger: On a schedule (every day at 06:00) (plus 3 other triggers).
- Get warmup accounts (cold_email_accounts) (Data table): get
- Get sent warmups to mark read (Data table): get
- Get accounts (for receiver creds) (Data table): get
- Get warmup accounts for queue (Data table): get

- Build conversation generation loop (Code): runs custom JavaScript code
- Merge: merges the data from its input branches
- Loop: build queue per inbox (Loop Over Items (Split in Batches)): loops over the items in batches
- If: checks a condition and branches into true / false
…plus 31 more steps. See the full node list below.
Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 1 community package, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that n8n-nodes-run-node-with-credentials-x is verified or supports 3.0 (used in Send Gmail message (new thread), Reply in existing Gmail thread, Label sent warmup email).
