Reply within minutes, then follow up on about day 1, 3, 7 and 14 with short, useful messages, and call as well. Inside the 24-hour window after the lead's last message you can send normal replies; outside it you must use approved templates. Stop when the lead replies, books or asks you to stop.
Following up with leads on WhatsApp works best as a short, planned sequence rather than ad hoc reminders. Reply within minutes, front-load your effort in the first day, then space messages out over about two weeks. Each message should be short and useful, and the sequence should stop the moment the lead replies, books or asks you to stop.
A simple follow-up cadence
| When | What to do |
|---|---|
| Day 0, within 5 minutes | WhatsApp message with one easy question, then a call |
| Day 0, a few hours later | Second call at a different time of day |
| Day 1 | Gentle nudge with one useful detail |
| Day 3 | A reason to talk: an offer, a slot or an answer to a common question |
| Day 7 | A specific slot or time-bound offer |
| Day 14 | Polite close-out that leaves the door open |
Adjust the gaps to your sales cycle: shorter for a holiday package, longer for a home purchase. The 2007 InsideSales.com and MIT study of web leads found contact and qualification odds fell sharply with time, which is why the first day matters most.
The WhatsApp rule that shapes every follow-up
According to Meta, when a person messages or calls your business, a 24-hour customer service window opens, and only inside it can you send normal free-form messages. Each new message from them restarts it. Outside the window, you can only send approved template messages.
- Lead messaged you in the last 24 hours: reply freely.
- Lead filled a form and never messaged: template only.
- Lead's last message was days ago: template only.
Most sales follow-ups are marketing templates. Meta's guidelines say utility templates must be non-promotional and tied to something the person did or asked for, such as an appointment confirmation, and Meta can re-categorise templates that do not fit. Meta charges per delivered template message by category and country, so a short sequence is also a cheaper one.
When to stop
- The lead replies. A person takes over; automated nudges stop.
- The lead books or buys. Switch to confirmations and reminders.
- The lead says no or stop. The WhatsApp Business Messaging Policy requires you to respect every opt-out. Record it so broadcasts skip them too.
- The sequence ends with no reply. Close the lead with a reason so reports stay honest.
Habits that make follow-up stick
- End every conversation with a dated next step in your CRM.
- Work overdue follow-ups first each morning, high priority on top.
- Log every call, even short ones, so the next person has the full story.
- Write templates in the language your leads use.
How salestrack helps
salestrack's automated follow-ups send sequences of approved templates by stage and source, with delays in hours or days, and stop on a reply, a stage change or an opt-out. Ready-to-use drip campaigns and workflows give you a tested starting point. The Follow-ups page and each salesperson's My day screen put overdue follow-ups first. Template messages are paid from a prepaid WhatsApp wallet; the app shows the exact rate before you send.
Related questions
How many times should I follow up a lead on WhatsApp?
For most new leads, four to five messages over about two weeks is enough, alongside two to four calls. More than that rarely helps and starts to feel like spam.
Can I send a follow-up message after 24 hours on WhatsApp?
Yes, but on the WhatsApp Business Platform it must be an approved template message. Free-form messages are only allowed inside the 24-hour customer service window that opens when the customer messages you.
Are WhatsApp follow-up messages free?
Not usually. Meta charges per delivered template message, by category and country. Chats from Click-to-WhatsApp ads can be free inside the free entry point window if you replied within 24 hours.
Should I call or WhatsApp a new lead first?
In India and the Gulf, many people will not pick up an unknown number but will read a WhatsApp message. Sending a short message first and then calling often works better than calling cold.
What if a lead asks me to stop messaging?
Stop all marketing messages to that number and record the opt-out. The WhatsApp Business Messaging Policy requires businesses to respect every opt-out request.
