# Using Collected Data in Follow-Up Messages

One of the most powerful features of waatee is the ability to personalize your chatbot messages based on collected user data. By using custom fields, you can store subscriber-specific information like name, email, phone number, or any other detail and then dynamically use those data points in your follow-up messages.

This guide walks you through how to create custom fields in waatee and use those fields in personalized WhatsApp messages within chatbot flows.

### **What Are Custom Fields and Why Use Them?**

Custom fields in waatee are user-defined data placeholders that let you collect and reuse subscriber information throughout your chatbot journey. These fields help you:

- Personalize messages with names, emails, or preferences.
- Store collected information for future campaigns or segmentation.
- Create advanced automation using dynamic conditions and content.
- Improve engagement and conversion by making conversations feel more human.

## **Step-by-Step Guide to Using Custom Field Data in Follow-Up Messages**

### **🔹 Step 1: Access WhatsApp Subscriber Manager**

Go to **Subscriber Manager → WhatsApp Subscriber** from your waatee sidebar.

Click the **Manage** button → Select **Manage Custom Fields**.

### **🔹 Step 2: Create a New Custom Field**

Click on the **Create** button to add a new field.

- **Custom Field Name:** Enter a unique identifier (e.g., full_name).
- **Reply Type:** Choose the appropriate format (Text, Email, Phone, Number, URL).

Then click **Save**.

### **🔹 Step 3: Insert Custom Fields into Your Message Flow**

Open your chatbot flow and add or edit a message block. In the message configuration window:

- Click on the **Custom → Field Name**
- Insert any of your created custom fields using the syntax: #field_name#.

Example message:

`Your data is:`

`Name: #full_name#`

`Phone: #User phn num#`

`Email: #User Email#`

`Address: #User Address#`

This will dynamically insert each user’s data into the message.

## **Tips for Using Custom Field Data Effectively**

- **Always validate input:** When collecting user input, use reply types like Email and Phone to ensure proper formatting.
- **Use meaningful field names:** Keep them short, lowercase, and descriptive (e.g., user_email, city).
- **Test your flow:** Preview the message with dummy data to confirm correct replacement.
- **Combine with conditions:** Use “Condition” blocks to check if a user has a value stored and branch logic accordingly.
- **Avoid redundant questions:** If a field is already populated, skip that step for returning users.
