An n8n workflow that reads new mail over IMAP, has a model on OpenRouter summarize each message and pushes the summary to a LINE chat. Email summaries from OpenRouter sent to a LINE chat is an n8n workflow in the Productivity category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Download it on this page or copy its JSON, then import it into an n8n canvas. Nothing runs until you activate it in n8n. ## About ### What it is This n8n workflow reads new mail over IMAP and sends each message to a model on OpenRouter. The model writes a short summary, and deadlines and action items come first when the mail matters. The summary is pushed to a LINE chat through LINE’s Messaging API. Three nodes run it, beside four sticky notes. ### Who it suits People who live in LINE and want their inbox condensed into short messages there. Skip it if you have no LINE channel with the Messaging API, or if you cannot send mail text to OpenRouter and its model providers. Who uses it, and how | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Family | Parents | Catch school and club deadlines | A parent gets the date a form is due in a chat message. | | Freelance | Freelancers | Skim client mail on the phone | A freelancer reads one line per message instead of opening the inbox. | | Operations | Small business owners | Spot payments and sign-up dates | An owner sees which supplier mail has a due date. | | Travel | Frequent travellers | Keep booking mail short | A traveller gets one line per booking change. | You need a little n8n, a LINE channel and two API credentials: import a file, add three credentials and paste your LINE user id. ### Where to use it Any n8n that can reach your mail server, OpenRouter and LINE will run it. The summaries arrive in the LINE chat of the user id you set. - n8n Cloud: import the file there and activate it - Your own n8n server: the same file and steps - OpenRouter: the model that writes the summaries - LINE: the chat that receives them ### How to set it up Download saves a zip with `workflow.json` and Mindket’s setup notes in your downloads folder. Setup takes three credentials and one user id. What you need first | Need | Detail | | --- | --- | | n8n | On n8n Cloud or on a server of your own | | Mailbox | IMAP host, port and login | | OpenRouter | An account and an API key | | LINE | A channel with the Messaging API, its channel access token and a user id | 1. In n8n, create a workflow, open its menu, choose Import from File and pick `workflow.json`. 2. Add an Email (IMAP) credential and select it in `Read emails (IMAP)`. 3. Add a Header Auth credential with the name `Authorization` and the value `Bearer `, using your key, and select it in `Send email to A.I. to summarize`. 4. Add a second Header Auth credential with the value `Bearer ` and select it in `Send summarized content to messenger`. 5. In that node, replace `` with the receiver’s id. 6. Activate the workflow and send yourself a mail. ### How to use it Activate the workflow and leave it running. A new unread mail is summarized, and the summary arrives in LINE a moment later. Edit the prompt to change what the summary stresses. What to change for a different result | To change | Where | | --- | --- | | The instructions to the model | The prompt in \`Send email to A.I. to summarize\` | | The model | \`model\` in the same body | | Which mail is read | The mailbox and options of \`Read emails (IMAP)\` | | Who receives the summary | \`to\` in the LINE body | ### Example A parent gets a school email about a trip and a payment due on the first of the month. The model replies with the due date in bold at the top and one line about the trip. LINE shows that message in the parent’s chat. ### For newcomers and experts **If you are new.** n8n draws a workflow as boxes joined by lines, and each box, a node, does one job. Here one box reads the mail, one asks the model and one posts to LINE. Try it with a mailbox that gets little mail. **For experts.** One IMAP trigger and two HTTP Request nodes with Header Auth, and no AI node. The email text is JSON-escaped inside the request body, and the summary is escaped the same way before the push. Where to look closer | Node | What it does | What to know | | --- | --- | --- | | \`Read emails (IMAP)\` | Fires for unread mail and leaves it unread | Version 2.2 remembers the last message id | | \`Send email to A.I. to summarize\` | Posts the mail to OpenRouter’s chat completions address | The model id is in the body | | \`Send summarized content to messenger\` | Pushes the text to LINE | The receiver is the \`to\` user id | ### Good to know Every unread mail becomes a model call and a LINE push, so a busy inbox can add up in cost. - The repair: OpenRouter’s public model list, read on 12 November 2026, no longer shows \`meta-llama/llama-3.1-70b-instruct:free\`. The same model without \`:free\` is listed, so this copy uses it, and it is no longer free - The IMAP node: version 2 fetches every unread message again on each arrival when mail is left unread, so this copy uses version 2.2 - The prompt: the mail text was URL-encoded before. It is JSON-escaped now, and the plain text part is used first - LINE: its pricing page, read on 12 November 2026, counts push messages toward the plan’s message count - Not run: this copy was not run against a mail server, OpenRouter or LINE - Your data: the sender, subject and text go to OpenRouter and its model provider, and the summary goes to LINE - Credentials: the JSON holds none ## README ```markdown # Email summaries from OpenRouter sent to a LINE chat An n8n workflow that reads new mail over IMAP, sends each message to a model on OpenRouter for a short summary, and pushes the summary to a LINE chat through LINE's Messaging API. ## What is inside - `workflow.json`: the workflow as n8n exports it, seven nodes: three that do the work and four sticky notes. It holds no credential. - `README.md`: these notes. ## What we changed from the original copy - The credential links are gone. Select your own for IMAP and for the two Header Auth steps. - The model was `meta-llama/llama-3.1-70b-instruct:free`. OpenRouter's public model list, read on 12 November 2026, no longer shows it. The same model without `:free` is listed with a context of 131072 tokens and a price of 0.00000072 USD per token for input and output, and the node uses it. It is no longer free. - `Read emails (IMAP)` moves from version 2 to 2.2. In n8n's source, versions up to 2 do not remember the last message seen, and this file leaves mail unread after processing. Each new arrival would then fetch every unread message again. Version 2.2 follows the message ids. - The email text in the prompt was URL-encoded, which keeps quotes and line breaks from breaking the JSON body but gives the model percent-encoded text. It is JSON-escaped now, and the plain text part is used, with the HTML part as a fallback. The summary sent to LINE is escaped the same way, so a quote in it cannot break the request. - The LINE user id is `` now. - The notes are rewritten. Two links and a remark about LINE's own node are removed. - Nothing else. ## Before you start - An n8n instance, on n8n Cloud or your own server. - A mailbox you can reach over IMAP, with its host, port and login. - An OpenRouter account and an API key. - A LINE channel with the Messaging API, its channel access token, and the user id of the person who should get the summaries. ## Set it up 1. In n8n, create a workflow, open its menu and choose Import from File. Pick `workflow.json`. 2. Add an Email (IMAP) credential and select it in `Read emails (IMAP)`. 3. Add a Header Auth credential for OpenRouter. Set the name to `Authorization` and the value to `Bearer `, with your key in place of the placeholder. Select it in `Send email to A.I. to summarize`. 4. Add a second Header Auth credential for LINE with the name `Authorization` and the value `Bearer `. Select it in `Send summarized content to messenger`. 5. In that node, replace `` with the receiver's user id. 6. Save and activate the workflow, then send yourself a mail. ## How a run goes 1. `Read emails (IMAP)` reads the inbox and fires for unread mail. It leaves each message unread. 2. `Send email to A.I. to summarize` posts the sender, subject and text to OpenRouter's chat completions address. The prompt asks for a summary of under ten words when the mail is unimportant, and for deadlines and action items, with an urgent marker, when it matters. 3. `Send summarized content to messenger` posts the summary as a text message to LINE's push address. ## Change the look - The instructions to the model: the prompt in `Send email to A.I. to summarize`. - The model: `model` in the same body. - Which mail is read: the mailbox and options in `Read emails (IMAP)`. - Who receives the summary: `to` in the LINE body. ## Good to know - LINE's pricing page, read on 12 November 2026, counts push messages toward a plan's message count. Reply messages are not counted. - OpenRouter bills the model per token. - An email with only an HTML part sends that HTML to the model, which makes a long prompt. - This copy was not run against a mail server, OpenRouter or LINE. - The sender, subject and body go to OpenRouter and its model provider. The summary goes to LINE. - The JSON holds no credential. ``` ## What is in it 3 files, 10 KB, downloaded as a zip. ```text NOTICE.md 679 B README.md 4 KB workflow.json 5 KB ``` ## Workflow check Checked by Mindket on 13 Nov 2026.
