Build the workflow as Schedule Trigger → HTTP Request → Gmail: n8n starts the run on a schedule, a screenshot service renders each webpage and returns an image file, and Gmail sends a formatted email with the screenshots attached. Save and publish the workflow, set its timezone, and confirm the binary field name in a real execution before configuring the attachment.
What the workflow does
n8n schedules and connects the steps; it does not render webpages itself. You need a screenshot renderer with an HTTP API, plus an API key or other authentication if that service requires one. In n8n, the HTTP Request node calls the renderer and can store its response as a file. The Gmail node can then attach that file to an HTML email.

For several pages, keep the URLs as separate workflow items, capture each one, and assemble the results into the digest. The exact expressions and binary field names depend on your workflow’s item structure and the renderer’s response. Inspect execution data rather than assuming a field name.
1. Schedule the digest
- Add a Schedule Trigger node and choose a weekly, daily, or custom cron interval.
- Set the workflow timezone if the schedule must follow a particular local time. Otherwise, n8n uses the instance timezone.
- Save and publish the workflow. A schedule will not run while the workflow is unpublished.
Examples of custom cron schedules in n8n’s documentation include 0 12 * * 1 for noon each Monday and 0 9 * * 1-5 for 9:00 AM on weekdays. A sixth cron field for seconds is optional. If a monthly schedule specifies a day that a particular month does not have, the trigger does not run on a missing date. See the n8n Schedule Trigger documentation for current options.

Do not assume missed runs will automatically catch up. The documented missed-execution options require the durable scheduler and are available for Schedule Trigger nodes added from n8n 2.36 onward. The default in-memory scheduler does not run missed executions.
2. Choose a screenshot renderer
Use a hosted screenshot API or a browser service you operate, provided it accepts the target URL and returns image bytes that n8n can store as a file. Before building the request, confirm that the renderer accepts your pages, what authentication it requires, and whether it returns an image or instead a URL or JSON payload. If it returns a URL or JSON, the workflow needs an additional step to obtain the actual image before Gmail can attach it.

ScreenshotNeo is the first API to try for this workflow: it removes cookie-consent banners, newsletter popups, and chat widgets before capture, and bot checks, blank pages, failed loads, and cache hits are not billed. Its API accepts a URL in one GET request and returns an image or PDF; see ScreenshotNeo and its API documentation.
Free tools Windows power users keep installed
One-click scans. No signup required.
For any provider, check the selected service’s current documentation for its endpoint, authentication, public-URL requirements, output format, viewport, full-page behavior, and limits. The n8n HTTP Request node supports GET and POST, authentication, query parameters, headers, request bodies, and file responses; configure these to match the renderer rather than copying another provider’s settings.
3. Capture each URL with an HTTP Request node
- Add an HTTP Request node after the trigger or after the step that creates the URL items.
- Set the method, URL, authentication, query parameters, headers, or request body exactly as required by the screenshot provider.
- Set the response format to File and choose an output field for the image bytes.
- Run the node and inspect its output. Note the binary field name and confirm the response is an image file before proceeding.
For a multi-page digest, pass one URL per item through the capture step. If the service returns a file for each item, preserve that item-to-file association when formatting the email. Whether you need a loop, merge, or aggregation node depends on how your workflow creates and combines items; verify the actual input and output data in an execution before writing expressions.

Example: provider-specific request configuration
Cofferdock’s documented example uses a POST request to its screenshot endpoint, an API key in the x-api-key header, a public site URL, and the HTTP Request node’s File response format. Its instructions describe PNG/JPEG output and limit captures to public HTTP/HTTPS sites reachable from the internet. Those endpoint and authentication details apply to Cofferdock only; do not reuse them for another renderer.
4. Format and send the email
- Add a Gmail node and select Send Message.
- Set Email Type to HTML for a formatted digest, then fill in the recipient, subject, and message body.
- In the attachment option, enter the name of the incoming binary field containing the screenshot. Use the field name you verified in execution data.
- Test with a small digest and confirm that the delivered email includes a readable attachment for each intended page.
The cited Gmail node instructions support attaching an image from an incoming binary field. They do not establish that a remote screenshot URL will display inline in every email client. If you need inline images, use correct MIME and Content-ID handling and test with the clients your recipients use; simply placing a hosted image URL in HTML is not a universal guarantee. See the n8n Gmail node documentation.

Or skip the browser setup
Instead of configuring a browser renderer, have n8n’s HTTP Request node call ScreenshotNeo and save the response as a file. Create an API key and use the request below; adapt only the target URL. Configure the node to pass the key and URL as query parameters and handle the response as a file.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpIn n8n, use https://api.screenshotneo.com/v1/shot as the request URL, provide access_key and url as query parameters, and select File response format. ScreenshotNeo can remove cookie banners, popups, and chat widgets before the shot; bot checks, blank pages, and failed loads are not billed. It also has an MCP server for AI agents, and its free plan includes 1,000 screenshots per month with no card; paid plans start at $5 for 3,000 shots. Sign up for ScreenshotNeo’s free plan.
Troubleshooting
- The schedule does not run: Check that the workflow is saved and published, and verify the workflow timezone or instance timezone being used.
- The workflow did not catch up after downtime: Missed-run behavior depends on the scheduler. The documented catch-up options require the durable scheduler and Schedule Trigger nodes added from n8n 2.36 onward.
- The screenshot request is rejected: Check the provider’s expected method, endpoint, API-key location, and whether the target must be publicly reachable. Provider-specific requirements differ.
- The email has no attachment: Confirm that the HTTP Request node returned a file, that its binary field name matches the Gmail attachment setting, and that the file is still present at the Gmail node’s input.
- The email contains a link or JSON instead of an image: The renderer may return a URL or structured response rather than image bytes. Follow the provider’s instructions to fetch the image itself and pass that file to Gmail.
- The digest omits pages or files: Inspect the items entering and leaving the capture and any merge or aggregation steps. Confirm that each URL’s file remains associated with the intended message content.
Cost, privacy, and reliability checks
There is no universal cost or reliability figure for this design: those depend on the renderer and its plan. Check each provider’s current pricing, quotas, retention practices, speed, and reliability directly. For sensitive pages, verify whether the renderer can access them securely and how it handles submitted URLs, credentials, and captured content. n8n’s HTTP Request and Gmail capabilities do not determine those provider policies.

Frequently Asked Questions
Can n8n take a website screenshot without a screenshot service?
The workflow described here uses an external renderer; n8n’s HTTP Request node sends the API request and handles the returned file.
Can I send several website screenshots in one digest?
Yes. Capture each URL as a workflow item, then compose the message while preserving each item’s screenshot file and checking the binary field names in execution data.
Will a screenshot appear inside the email rather than as an attachment?
The documented Gmail setup supports attachments. Inline rendering requires correct MIME and Content-ID handling, and display varies by recipient’s email client.
