Gmail → OpenAI → Slack

Each new Gmail message is summarized by OpenAI and the summary is posted to Slack.

Steps

When when a new email arrives in gmail — Gmail node only reads
Then summarize it with openai — OpenAI node can be undone
Then send the summary to slack — Slack node can’t be undone

Fields to fill (4)

The file has every node wired up. These are the blanks only you can fill (your form, your sheet, your words).

Node	What to do
OpenAI	fill `modelId` (Model)
Slack	check `select` = 'channel' (first option; pick yours)
Slack	fill `channelId` (The Slack channel to send to) — only if select = channel
Slack	fill `text` (The message text to post) — the AI step's output: run that node once in n8n and pick its output field

Accounts to connect (3)

In n8n, pick or add a credential on each node — one of the types below.

Gmail: googleApi or gmailOAuth2
OpenAI: openAiApi
Slack: slackApi or slackOAuth2Api

Need something slightly different? Same engine, your own words:

Run it on Apify — type your own sentence, get the workflow back in seconds. Open Bridgecore on Apify (pay per use, $0.02–$0.05; nothing charged on errors).
Ask your AI — add the MCP server https://mcp.usebridgecore.com/ to Claude, Cursor or any MCP client, then just say what should happen. Tools: do, find_recipe, plan_automation, make_n8n_workflow. Free to plan.
Ask me first — add “and ask me first” to any step (“… and post it on X and ask me first”) and the workflow sends you an Approve / Decline message (Slack, Telegram or Gmail) before that step runs. Nothing is sent, posted, deleted or paid until you tap Approve; no answer in a day = declined.

Download gmail-summary-to-slack.json

Open a new, empty workflow in n8n.
Open the workflow menu (⋯) and choose Import from File — or copy the JSON below and paste it onto the canvas (Ctrl/Cmd+V).
Connect the accounts, fill the fields above, run one test, then turn the workflow on.

Or copy the JSON
