Auto WhatsApp after every call: the follow-up that sends itself
The message you promise on the call is the one that gets forgotten. How automatic WhatsApp messages after a call, on a status change or on a missed call work, with templates, quiet hours and an ask-first mode.

Every good call ends with a promise: “I’ll WhatsApp you the brochure.” Then the next call comes in, and the promise waits until evening, or forever. Auto WhatsApp keeps it for you.
Three triggers, one habit
After a call. Outgoing or incoming, when the call ends a message goes: “Nice speaking with you, Sharma ji. Here is the brochure. Site visit Sunday 11 am, see you then.” Sent while the customer is still holding the phone.
On a missed call. Customer calls, caller is on another line. “Sorry I missed you, calling you back in ten minutes.” Missed enquiries stop being lost enquiries.
On a status change. The caller taps Interested; the price list goes. Taps Proposal sent; the payment link goes. The status is already the decision; the message rides on it.
Templates that read like a person
Write them in your voice, with variables: name, product, price, appointment time, caller name. Keep them short. Add the caller’s own name so the reply comes back to the right person. Different templates per trigger and per status.
Guardrails that keep it human
- Quiet hours. Nothing sends at 11 pm; it waits until morning.
- Cooldown. One automatic message per contact per window, so three short calls do not mean three brochures.
- Ask-first. The message is prepared and the caller confirms with a tap. Ideal for the first weeks and for sensitive statuses.
- Per-trigger switches. Turn missed-call replies on for the sales line and off for support.
- History. Every automatic message shows on the contact’s timeline: what went, when, which trigger.
Personal WhatsApp or the API?
For a small team sending a few dozen messages a day, the WhatsApp or WhatsApp Business app on the phone works. For higher volumes, templated messages and an inbox the whole team can see, connect a WhatsApp Business API provider; SensyConnect supports both and the same triggers apply.
What changes
Follow-up rate goes to 100 percent because there is no follow-up step. Replies come in while the conversation is warm. And the caller’s rhythm holds: no stopping to type, no evening backlog.
Auto WhatsApp is included in the one plan. See the features page or start the free trial and turn on the after-call trigger.
Frequently asked
Does it use my personal WhatsApp or the API?
Both are supported. Personal or Business app for small volumes; the WhatsApp Business API through a provider for higher volumes and templates.
Can I stop it messaging the same person twice?
Yes. A per-contact cooldown and per-trigger rules prevent repeats; quiet hours hold messages until morning.
What if I want to review before sending?
Turn on ask-first: the message is prepared and the caller confirms with a tap. Great for the first month, and for statuses like Not interested.
