1.1 Workflow description

Title: Bulk WhatsApp & Gmail messenger with Google Sheets status tracking via InboxPlus
Workflow name: Bulk WhatsApp & Gmail messenger with Google Sheets status tracking via InboxPlus

How it works

This workflow sends WhatsApp messages and emails in bulk using contact data stored in Google Sheets. Contacts are processed in small batches to control throughput and avoid API rate limits. WhatsApp and email are treated as independent channels and are sent only when their status is marked as pending. All success and failure results are written back to Google Sheets to enable tracking, retries, and safe re-runs.

Step-by-step

Step 1: Fetch contacts & batch processing
- Manual Trigger – Starts the workflow manually.
- Get Contacts – Reads contact data from Google Sheets.
- Split In Batches – Processes contacts in controlled batch sizes.
Step 2: Email preparation & sending
- Has Email Address – Checks whether the contact has an email address.
- IF Mail Pending – Ensures the email is still marked as pending.
- PrepareEmail email – Loads the selected InboxPlus email template.
- Build HTML Email – Builds the final HTML email body.
- Fetch Email Image – Downloads images for inline or attachment usage.
- Send Gmail – Sends the email via Gmail.
- Delivered – Confirms successful email delivery.
Step 3: WhatsApp message sending
- Has Phone Number – Checks whether the contact has a phone number.
- IF WhatsApp Pending – Ensures the WhatsApp message is still pending.
- Send template – Sends the approved WhatsApp template message.
- Sent – Confirms message acceptance by WhatsApp.
Step 4: Delivery status updates
- Update Sheet – Writes successful delivery results back to Google Sheets.
- Mail Failure – Updates Google Sheets if email delivery fails.
- Whatsapp Failure – Updates Google Sheets if WhatsApp delivery fails.

Why use this?

Prevents duplicate messages with channel-level pending checks
Handles WhatsApp and email independently in one workflow
Supports safe retries without resending completed messages
Keeps Google Sheets as the single source of truth
Scales bulk outreach safely using batch-based execution

Promote YouTube uploads to social channels with DeepSeek and Posta

## Quick overview This workflow fetches the latest video from a YouTube channel feed, generates platform-specific promo captions with DeepSeek, and creates draft promotion posts in Posta for active social media accounts. You can automatically promote your videos to all your social media. Add a "publish" at the end for auto-post. ## How it works 1. Runs manually when you click “Execute workflow”. 2. Fetches your YouTube channel RSS feed over HTTP, parses the XML, and extracts the latest video’s title, description, thumbnail URL, and link. 3. Downloads the video thumbnail and uploads it to Posta to create a reusable media asset. 4. Retrieves your social accounts from Posta, keeps only active accounts, and de-duplicates them to one account per platform. 5. Combines the latest video data with each target platform and asks DeepSeek (via an n8n LangChain LLM chain) to write a tailored promotional caption per platform. 6. Tags each generated caption with its platform and merges it back to the matching Posta social account. 7. Creates a draft Posta post per selected account, attaching the uploaded thumbnail and the platform-specific caption and video link. 8. (Optional) Add a "publish a post" at the end to automatically post to the social media channels (If you are feeling brave and trust the LLM), ## Setup 1. Add a Posta API credential and select it in the Posta nodes that list accounts, upload media, and create posts. 2. Add a DeepSeek API credential and select it in the DeepSeek Chat Model node. 3. Update the YouTube channel feed URL (channel_id) in the HTTP request that downloads the YouTube feed. 4. Review your Posta social accounts to ensure the intended accounts are marked active and have the correct platform values for de-duplication. ## Additional info Video explanation: https://youtu.be/tTWaYb71YyA

Post scheduled Threads updates from Google Sheets with error tracking

## Quick overview This workflow runs hourly to read the next pending post from Google Sheets, publishes it to Threads via the Threads Graph API, and then updates the sheet with published or failed status plus timestamps and error details. ## How it works 1. Runs every hour on a schedule. 2. Reads the first row in Google Sheets where the status column equals pending. 3. Retrieves the authenticated Threads account’s user ID from the Threads Graph API. 4. Creates a Threads text post container using the content from the pending Google Sheets row. 5. Publishes the post to Threads and updates the same Google Sheets row as published with posted_at and updated_at timestamps. 6. If any Threads API call fails, records the error message and marks the corresponding Google Sheets row as failed with an updated_at timestamp. ## Setup 1. Create a Meta app and generate a Threads access token, then add it to an HTTP Header Auth credential used for the Threads Graph API requests. 2. Set up a Google Sheets Service Account credential in n8n and share your target spreadsheet with the service account email. 3. Replace the placeholder Google Sheet ID in all Google Sheets nodes and confirm the sheet name is Sheet1 (or update it to match your sheet). 4. Ensure your sheet has the required columns (row_number, content, status, posted_at, updated_at, error_message) and set status to pending for posts you want published.

Send a daily product newsletter with Google Sheets and Gmail

## Quick Overview This workflow runs daily at 08:00, pulls products scheduled for today from Google Sheets, generates an HTML newsletter email, and sends it to each subscriber via Gmail. ## How it works 1. Runs every day at 08:00 on a schedule. 2. Reads all rows from the `newsletter_products` sheet in Google Sheets. 3. Keeps only products whose `send_date` matches today’s date and stops if none are found. 4. Builds an HTML email and subject line containing a card for each product (image, description, and optional referral link). 5. Reads the subscriber list from the `newsletter_recipients` sheet in Google Sheets. 6. Sends the generated newsletter to each recipient individually using Gmail. ## Setup 1. Create or copy a Google Sheets document with `newsletter_products` (including a `send_date` column) and `newsletter_recipients` (including an `email` column). 2. Add a Google Sheets OAuth2 credential in n8n and paste your Google Sheet ID into the Config step. 3. Add a Gmail OAuth2 credential and confirm the sender mailbox to use for sending the newsletter. 4. Add products and recipients to the sheet, run a test execution, and adjust the schedule/timezone if needed before activating.
