How It Works

1

Write Your Template

Compose a message using {{variable}} placeholders for the parts you want to personalise — names, order IDs, dates, or anything else.

2

Paste Your CSV Data

Add CSV data with column headers matching your variables. Each row becomes a unique, personalised message.

3

Preview, Copy & Export

Instantly preview every generated message in a WhatsApp-style bubble. Copy individually, copy all, or export as CSV/TXT.

Plan Personalised WhatsApp Bulk Messages

Sending the same generic message to every contact is a sure way to get ignored. With the WhatsApp Bulk Message Planner, you write one template and let variables handle the personalisation. Every recipient sees their own name, order number, or any custom detail you need — without you copying and pasting anything by hand.

This tool runs entirely in your browser. No data is uploaded to any server. Your contacts, messages, and CSV data stay on your device, making it safe for customer communications and GDPR-sensitive workflows.

How Template Variables Work

Variables are placeholders wrapped in double curly braces, like {{name}} or {{order_id}}. When you paste CSV data, the tool matches each column header to its corresponding variable and replaces it for every row.

You can use any variable name you like. Common examples include:

VariableUse Case
{{name}}Recipient's first name
{{company}}Company or business name
{{order_id}}Order or invoice number
{{amount}}Payment or invoice amount
{{date}}Appointment or delivery date
{{link}}Tracking URL or resource link

When to Use the Bulk Message Planner

  • Order updates — Notify every customer about their specific shipment status, delivery date, or tracking link without writing individual messages.
  • Appointment reminders — Send personalised reminders with the correct date, time, and location for each client.
  • Event invitations — Address each invitee by name and include their unique RSVP link or seat assignment.
  • Payment follow-ups — Politely remind clients about outstanding invoices with the exact amount and invoice number.
  • Customer onboarding — Welcome new signups with their account details, login link, and assigned account manager's name.

Best Practices for WhatsApp Bulk Messaging

WhatsApp has strict policies on bulk messaging to prevent spam. Follow these guidelines to keep your account safe and your messages effective:

  • Always get opt-in consent — Only message contacts who have explicitly agreed to receive messages from you. This is a WhatsApp Business requirement.
  • Personalise every message — Generic broadcasts get reported as spam. Using variables to include the recipient's name and relevant details dramatically improves engagement.
  • Keep it concise — WhatsApp is a conversational channel. Messages should be brief, actionable, and friendly.
  • Respect timing — Avoid sending messages late at night or early in the morning. Business hours in the recipient's time zone are best.
  • Use the WhatsApp Business API — For serious bulk messaging at scale, use the official API through a WhatsApp CRM integration rather than manual sending.

Automate It With a WhatsApp CRM Integration

Planning messages manually works for small batches, but as your business scales you need automation. A WhatsApp CRM integration lets you trigger personalised messages automatically based on CRM events — new deals, status changes, follow-up reminders, and more.

Appstronauts builds native WhatsApp integrations for CRMs like Attio and Affinity. Every conversation is logged, every contact is synced, and your team never misses a message. Set it up in five minutes and let it run forever.
