Features of DMerge Notifier
────────────────────
⇨ Bulk Messaging: Send personalized direct messages from Google Sheets™ to many recipients in just a few clicks — perfect for communicating with large groups effortlessly.

⇨ Multiple Platform Integrations: Send personalized Emails, Slack DMs and WhatsApp messages in bulk. Connect securely to the Slack API and WhatsApp Cloud API and send right from Google Sheets™ — no switching between platforms.

⇨ Google Doc™ & PDF Merge: Turn a Google Doc™ into a template and generate one personalized document per row — saved straight to a Drive™ folder of your choice. Output as Google Docs™ or PDFs, with custom file names built from your spreadsheet columns. Run it from the source spreadsheet, or open the add-on directly inside any Google Doc™ to use that document as the template.

⇨ Automatic Recipient Sharing: Optionally grant each recipient Viewer, Commenter or Editor access to their generated document — with the option to suppress Drive's™ default sharing email for a cleaner experience.

⇨ Merged Documents in Your Messages: The link to each recipient's generated Doc/PDF becomes a merge field you can drop into your Email, Slack or WhatsApp message — so people receive their personalized document and a message together.

⇨ Dynamic Fields for Personalization: Use spreadsheet column headers as placeholders to personalize every message and document. Example: replace {{Name}} with the actual name from your sheet.

⇨ Support for Dynamic Lists: Build customized messages with itemized lists using repeated columns in the spreadsheet, rendered natively per channel (bulleted lists in Email, Slack and WhatsApp). Ideal for detailed or itemized notifications.

⇨ Display Formatting Preserved: Merged values keep the exact formatting shown in your sheet — percentages, currencies, dates and more come through just as they appear.

⇨ Preview before Sending: Visually preview your personalized content within the app, and send a controlled test message to yourself or a specific user before starting a bulk send.

⇨ Customizable Templates: Create reusable message and document templates with dynamic fields, reducing repetitive work and keeping everything consistent.

⇨ Scheduled Sending: Defer and automate sends on an hourly or daily schedule.

⇨ User-Friendly Interface: Intuitive, with step-by-step guidance, file/folder pickers and tooltips to help you get started quickly.

⇨ Lightweight and Secure: DMerge Notifier processes data within your Google Workspace™ using secure Google and platform APIs, keeping your data private.

(Optional) Set Up Document Merge: Choose a Google Doc™ template and an output folder to generate a personalized Doc or PDF for each recipient — and optionally share it with them.

Data Privacy and Security
─────────────────
We prioritize your privacy and maintain high security standards:

No Data Storage: DMerge Notifier does not store or transmit your spreadsheet, document or messaging data to third-party servers. All processing occurs through Google and platform (Slack/WhatsApp) APIs.

Minimal Permissions: The add-on requests only the permissions needed for its core functionality. Document merge uses per-file Drive access (the files you pick or create), not broad access to your Drive.

Secure Connections: All interactions with Google and platform APIs use secure, encrypted channels.

User Control: You retain full control over your data and can revoke permissions at any time through your Google, Slack or Meta account settings.
