Most businesses treat their CRM like a digital graveyard. They spend heavily on top-of-funnel acquisition while thousands of leads sit dormant in their database. Database reactivation is more than a marketing tactic. It is a technical process of re-engaging warm leads through high-deliverability channels.

That channel is WhatsApp. With a 98% open rate and being the most used messaging channel in the world,  it bypasses the noise of email and the high costs of SMS. However, running a successful campaign requires more than just sending a message. You need a structured technical workflow to handle compliance, deliverability, and conversion.

How a Reactivation Campaign Works

A successful campaign follows a clear process. You start by pulling a list of contacts who haven't interacted with you in 3 to 6 months. Then, you create a "low-friction" offer. This could be a free consultation, a limited-time discount, or an exclusive update.

The AI then sends a personalized message via WhatsApp. If the customer replies, the AI handles the follow-up. If they are ready to buy or need a deeper talk, the system hands the lead over to your sales team or drops a booking link directly in the chat.

Step 1: Data Segmentation and Hygiene

A reactivation campaign starts with your data. You shouldn't message every old contact at once. Instead, filter your CRM for specific segments:

• Dormant Leads: No interaction in the last 90 to 180 days.

• Past Customers: People who bought once but haven't returned.

• Abandoned Inquiries: Leads who asked a question but never converted.

By segmenting your list, you can tailor your message templates to the specific context of their last interaction. This increases relevance and reduces the risk of being reported as spam.

Step 2: Data Segmentation and Hygiene

To send messages at scale, you must use the WhatsApp Business API rather than the standard Business App. This allows you to use AI Autonomous Agents to handle replies and manage high volumes.

The API operates under strict rules set by Meta. Every outbound message initiated by the business must use an approved Message Template. These templates must fall into specific categories like "Marketing" or "Utility." According to the WhatsApp Business Policy, you must also include a clear way for users to opt out. Maintaining a high "Quality Rating" on your phone number is essential to avoid messaging limits that could throttle your campaign.

Step 3: The 24-Hour Session Window

The real power of the API kicks in once a user replies. This opens a "Customer Service Window," a 24-hour period where you can send free-form messages without using templates.

This is where ThaigerGo CRM takes over. Instead of a human salesperson manually typing replies, an AI agent parses the user's intent. If the user asks a question, the AI answers using your business's knowledge base. If they show interest, the AI can immediately drop a booking link or update their status in your CRM.

Step 4: Automating the Hand-off

A technical reactivation campaign shouldn't just "talk"—it should "do." Your workflow should include automated triggers based on user behavior:

• Positive Intent: If the AI detects interest, it triggers a webhook to notify your sales team or moves the lead to a "Hot" pipeline.

• Opt-out: If the user says "Stop," the system automatically updates their CRM record to prevent future outreach, ensuring compliance.

• No Response: If there is no reply after 48 hours, the system can log the attempt and schedule a follow-up through a different channel.

Measuring the Impact

Here's what makes reactivation so profitable: you skip the expensive part of marketing. No lead gen costs. Just software, setup, and converting leads you've already paid to acquire.

When you reach out on WhatsApp instead of email, something shifts. The conversation feels real. Customers respond faster. They're more likely to buy. Meta's own research confirms it: personalized, conversational marketing builds relationships that ads never will. You're not interrupting someone's inbox. You're meeting them where they already are.
