Lead follow-up automation sends a set message at a set point after an enquiry or a finished job, based on what the CRM records. This post covers the response-time evidence, the main follow-up sequences, and the WhatsApp and Malaysian data-protection rules that limit what can be sent.
Response speed
The Harvard Business Review study measured how long US companies took to answer a web enquiry. The data is from 2011 and covers US firms.
| Response | Share of companies |
|---|---|
| Within one hour | 37% |
| One to 24 hours | 16% |
| More than 24 hours | 24% |
| Never answered | 23% |
| Average response time, companies that answered within 30 days | 42 hours |
A separate study of 1.25 million sales leads found that companies that tried to contact a lead within an hour were nearly seven times as likely to qualify it as companies that tried an hour later, and more than 60 times as likely as companies that waited 24 hours or longer. The study defined qualifying as a meaningful conversation with a key decision maker.
The authors named three causes of slow response: leads retrieved from CRM databases daily instead of continuously, sales staff focused on generating their own leads, and distribution rules based on geography and fairness.
Follow-up sequences
Each sequence starts from a trigger recorded in the CRM. The business sets the timing and wording for each service.
| Sequence | Trigger | Purpose |
|---|---|---|
| Enquiry acknowledgement | A new enquiry is recorded | Confirms receipt and starts qualification |
| Post-service check-in | A job is marked complete | Confirms satisfaction and routes any reported problem to staff |
| Repeat reminder | The next-due date, calculated from service type and completion date | Prompts the customer to book the next service |
| Referral request | A positive satisfaction record | Asks whether anyone the customer knows needs the same service |
| Win-back | No booking for a period the business sets | Refers to the previous job and offers a way to book |
Lifecycle stage decides which sequence applies. A first-time customer, a regular customer and a lapsed customer receive different messages.
WhatsApp rules
The WhatsApp Business Messaging Policy sets three conditions that apply to automated follow-up.
- A business may contact a person on WhatsApp only with that person's opt-in permission to receive later messages.
- Free-form replies are allowed inside a 24-hour customer service window, which opens and resets with each message from the customer.
- Outside that window, only approved message templates can be sent.
A follow-up scheduled days after a job therefore uses an approved template. The policy also requires automation to have a prompt, clear and direct escalation path to a person, such as in-chat agent transfer, a phone number or an email address.
Data protection
Section 6(1)(a) of the Personal Data Protection Act 2010 bars processing personal data without the consent of the data subject, subject to the exceptions in section 6(2). One exception covers processing necessary for steps taken at the data subject's request with a view to entering into a contract.
Section 43 lets a data subject require a data user, by written notice, to stop or not begin processing their personal data for direct marketing. The Act defines direct marketing as the communication of any advertising or marketing material directed to particular individuals. A win-back offer is marketing material directed to a named customer.

What OtomoAI builds
OtomoAI builds these sequences into the CRM layer. Triggers are job completion status, time elapsed, satisfaction score and lifecycle stage. A problem reported by a customer is routed to staff.
