Step 2: Connect Gmail and Fetch Recent Messages

Retrieve the last 24 hours of labeled emails to build the digest input.

1. Add the Retrieve Recent Emails node.
2. Credential Required: Connect your Gmail credentials.
3. Set Operation to getAll.
4. Set Limit to 20 and Simple to false.
5. In Filters → Label IDs, set the value to [YOUR_ID].
6. Set Filters → Received After to {{$now.minus({days: 1}).toISO()}}.
7. Connect Retrieve Recent Emails to Conditional Gate.

Step 3: Set Up the Conditional Gate and AI Summarization Chain

This step checks for email results and summarizes them using the AI chain with a document loader and text splitter.

1. In Conditional Gate, configure the condition with Left Value set to {{$items().length}}, Operation set to gt, and Right Value set to 0.
2. Connect the true output of Conditional Gate to Email Summary Chain, and the false output to No-Op Placeholder.
3. In Email Summary Chain, set Operation Mode to documentLoader and keep Summarization Method as stuff with the provided prompt text.
4. Configure OpenAI Chat Engine with Model set to o4-mini and connect it as the language model for Email Summary Chain.
5. Set Recursive Text Divider Chunk Size to {{ $json.text.length }} and connect it to Standard Document Loader as the text splitter.
6. In Standard Document Loader, set JSON Data to {{ $json.text }}, JSON Mode to expressionData, and Text Splitting Mode to custom.

Step 4: Map Summary Output and Assemble the Digest

Standardize fields from the AI output and combine all summaries into a single HTML digest.

1. In Map Output Fields, add assignments for:
   • output.text = {{ $json.output.text }}
   • subject = {{ $('Retrieve Recent Emails').item.json.subject }}
   • headers.from = {{ $('Conditional Gate').item.json.headers.from }}
2. Connect Email Summary Chain to Map Output Fields, then connect Map Output Fields to Merge Subject and Body.
3. In Merge Subject and Body, keep the provided JavaScript that builds combinedContent and returns a single item.

Step 5: Configure the Digest Email Output

Send the compiled HTML digest to your inbox.

1. Add the Dispatch Digest Email node and connect it to Merge Subject and Body.
2. Credential Required: Connect your Gmail credentials.
3. Set Send To to [YOUR_EMAIL].
4. Set Message to {{ $json.combinedContent }}.
5. Set Subject to Daily Tech-News Digest for {{ $now.toISODate() }}.

Step 6: Test and Activate Your Workflow

Run a manual test to confirm each stage works before turning on the schedule.

1. Click Execute Workflow to run Scheduled Run Trigger manually.
2. Verify that Retrieve Recent Emails returns items and that Conditional Gate routes to Email Summary Chain (not No-Op Placeholder).
3. Check that Merge Subject and Body outputs a single item with combinedContent.
4. Confirm the email arrives from Dispatch Digest Email with the expected subject and HTML digest body.
5. Toggle the workflow to Active to enable the daily schedule.
