How to Automate Follow-Ups on WhatsApp With AiSensy

When a lead ignores your first message, a timely WhatsApp follow-up is often all it takes to revive the conversation and clinch the sale. Yet doing it manually doesn’t scale.

In this guide you’ll discover exactly how to automate follow-ups on WhatsApp with AiSensy, so every prospect or customer receives the right nudge at the right moment.

What it is: Understanding Automated WhatsApp Follow-ups

Automated WhatsApp follow-ups refer to the process of sending pre-scheduled or trigger-based messages to your contacts on WhatsApp without manual intervention.

These messages can serve various purposes, from reminding customers about abandoned carts to sending post-purchase feedback requests or sharing updates. The goal is to maintain engagement, drive desired actions, and provide a seamless customer experience.

Manual follow-ups on WhatsApp can be time-consuming and prone to human error, especially as your business scales. WhatsApp automation, however, ensures consistency, timeliness, and efficiency, allowing your team to focus on more complex tasks. It's about being present and responsive for your customers, exactly when they need you.

Examples of Effective WhatsApp Follow-ups

To truly grasp the power of automated WhatsApp follow-ups, let's look at some real-world scenarios where they make a significant difference:

1. Abandoned Cart Reminders: 

A customer adds items to their cart on your e-commerce site but doesn't complete the purchase. An automated WhatsApp follow-up can send a friendly reminder, perhaps with a small discount, to encourage them to complete their order.

“Hey {{name}}, noticed you left {{product_name}} behind. Grab it now with free shipping: {{checkout_url}}."

2. Payment Pending / COD Verification:

A customer has chosen Cash on Delivery (COD) but hasn't confirmed the order, or a payment link has expired. A WhatsApp follow-up can secure the confirmation needed to ship the product.

“Kind reminder: your COD order #{{order_id}} awaits confirmation. CTA 1: Confirm order. CTA 2: Cancel.”

3. Post-Purchase Feedback Requests: 

After a customer receives their product, a follow-up message can be sent to ask for their feedback or review. This helps in gathering valuable insights and improving customer satisfaction.

"Hi {{name}}, thanks for your recent purchase of {{product_name}}! We'd love to know what you think. Could you spare a moment to leave a review? {{review_link}}"

4. Service Appointment Reminders:

For service-based businesses, automated reminders for upcoming appointments can significantly reduce no-shows.

"Hello {{name}}, this is a friendly reminder of your appointment with {{service_provider}} on {{date}} at {{time}}. Please reply 'YES' to confirm your attendance. We look forward to seeing you!"

5. Webinar/Event Reminders: 

Boost your Event & Webinar attendance with WhatsApp. If someone registers for a webinar or event, a series of  follow-up messages can be scheduled to remind them of the date, time, and how to join.

“Hi {{name}}, our webinar starts in 1 hour. Join here: {{join_link}}. See you soon!”

6. Subscription Renewal Alerts:

For subscription services, a timely reminder before renewal ensures continuity and reduces churn.

"Hi {{name}}, your subscription for {{service_name}} is set to renew on {{date}}. To ensure uninterrupted access, please review your details here: {{renewal_link}}. Thanks for being with us!"

7. Lead Nurturing in Real Estate:

After a potential buyer inquires about a property via WhatsApp, a follow-up message could share virtual tour links or book a site visit:

"Hello {{name}}! Thanks for your interest in our downtown apartments. Here's a quick tour—when would you like to visit?"

8. Healthcare Appointment Follow-Ups:

Clinics can enhance appointment scheduling, boost patient communication, and deliver real-time medical support with AiSensy's powerful WhatsApp automation.

Use WhatsApp to trigger Healthcare follow-up messages like: 

"Your check-up is tomorrow at 10 AM. Reply 'Confirm' or 'Reschedule'."

9. Lead Nurturing Sequences: 

After an initial inquiry, a series of automated messages can provide more information, answer common questions, and guide the lead through the sales funnel.

"Hi {{name}}, following up on your interest in {{product/service}}. Here is a short guide that explains how it can help you achieve {{benefit}}: {{guide_link}}. Do you have 15 minutes for a quick chat tomorrow?"

These examples highlight how a strategic WhatsApp follow-up can transform customer interactions and drive business objectives.

1. Using API Campaigns for Triggered Notifications

AiSensy's API campaigns are the backbone for automating WhatsApp follow-ups directly from your CRM or other third-party systems. This triggers messages based on user actions, like form submissions or purchases, for timely follow-up on WhatsApp.

Here's how to set it up:

• Log in to your AiSensy dashboard.
• Go to Campaigns > +Launch > API Campaign.
• Name your campaign, choose a pre-approved WhatsApp template, and set it live.
• Use the API endpoint (POST https://backend.aisensy.com/campaign/t1/api/v2) to send messages programmatically.

In your code, fill a JSON payload with essentials like apiKey (from your dashboard), campaignName, destination (user's phone number, e.g., +917428526285), userName, and optional fields like templateParams for custom content.

Example: If a user leaves a lead form incomplete, send an automated WhatsApp follow-up: "Hi [UserName], we saw your interest in our services—here's more details!"

Benefits: Enjoy high open rates (up to 98%), easy CRM connections (like HubSpot), and response tracking. Many businesses see 30-50% more lead conversions with these targeted WhatsApp follow-ups.

4. Use Broadcasts and Segmentation for Smarter Follow-ups

With AiSensy, you can easily segment your audience by factors like purchase history, engagement level, or demographics — and send follow-up broadcasts tailored to each group. Even better, you can schedule your WhatsApp broadcasts up to 2 months in advance, so every message goes out at the perfect time, completely hands-free.

Instead of sending one-size-fits-all messages, create personalized follow-ups that actually resonate. For example, share a new product update with customers who’ve bought similar items before, or send a reactivation message to users who’ve been inactive for a while.

This level of targeting and automation turns WhatsApp follow-ups into a powerful growth tool — boosting engagement, conversions, and long-term customer loyalty. With AiSensy, your follow-ups practically run themselves.
