What is a Follow-Up Chatbot?

A follow-up chatbot is an automated system that sends reminder messages to users who have interacted with your chatbot but haven’t completed an action, such as making a purchase or signing up. It helps businesses stay engaged with potential customers and improves conversion rates.

Why Use an Automated Follow-Up System?

  • Increases sales and conversions.
  • Ensures users don’t forget about your offer.
  • Works 24/7 without manual effort.

Building Your Follow-Up Chatbot

Creating the Chatbot Flow

  • Go to WhatChimp Dashboard> Bot Manager> Bot Reply > Create

  • Name the chatbot something recognizable, like Follow-Up Bot.
  • Save the chatbot and ensure it is triggered when a user interacts with a product-related message.

Setting Up Interactive Messages

  • Add an interactive block to your chatbot.
  • Create a message like: “Hey, Would you be interested in our product?” with Yes and No buttons.
  • If the user selects Yes, provide them with a checkout link.
  • If the user selects No, end the conversation or offer assistance.

Applying Labels to Track User Actions

  • When a user clicks “Buy Now,” apply a label called Buy Now.
  • If the user does not click the button, they do not receive this label.
  • Use this label to determine who needs a follow-up reminder.

Configuring the Follow-Up Sequence

  • Drag and drop the connector from the Buy Now button’s ‘Subscribe to Sequence’ option to begin a new follow up sequence to send a reminder message if the user does not purchase within 30 minutes or whatever time you choose.

  • Add a condition to follow up based on whether they selected the ‘Buy Now’ button or not

  • If False, send the follow up message

  • You can then include the Buy Now button

  • You can repeat the process to send another reminder if they still haven’t purchased.

Scheduling Messages for Maximum Engagement

  • Schedule your reminders strategically to avoid spamming users.

Exporting Chatbot Flows

  • You can export your chatbot flow and share it with others.

Now you know how to build an automated follow-up chatbot for WhatsApp! This system ensures potential customers are reminded of their interest in your product, increasing the likelihood of a sale. Try implementing these steps and refine the sequence based on user engagement.
