Auto WhatsApp: Messages that send themselves on events: a call ending, a lead status changing, a sale: so the promised details arrive while interest is at its peak.
Definitions checked 2 September 2026.
Auto WhatsApp is a message that a system sends because something happened, rather than because someone remembered to type it. A call ends and the price list goes out. A missed call is logged and "sorry we missed you, how can we help" goes out. A lead moves to Interested and the brochure goes out; to Won and the thank-you goes out. A follow-up reminder fires and its message goes with it. Set once per trigger, it runs every time, at the moment the message is most likely to be read.
Timing is the whole point. A price list that arrives while the customer is still thinking about the call gets opened; the same message two hours later, typed by hand when the caller gets a moment, usually does not. On a busy day the hand-typed version simply does not happen, and the customer who was ready at 11:40 hears nothing. Automation removes the dependence on memory and on a free minute.
Done carelessly it becomes spam, so the controls matter as much as the triggers: a per-number cooldown so nobody gets two messages in quick succession, quiet hours, an ask-before-send mode for high-value moments, an excluded list, and a history that logs every message as sent, skipped or failed with the reason. RMDialer, which we make, has all of these, sends through the official API with approved templates or opens WhatsApp with the text ready where a personal touch matters, and lets each call type and each lead status carry its own message. The feature page linked below shows how it is set up.
Can WhatsApp messages be sent automatically after a call?
Yes, on the official Business API with an approved template, or by opening WhatsApp with the message pre-filled. Each call type (missed, outgoing, incoming) can carry a different message.
Will automatic WhatsApp annoy customers?
Not if it is triggered by something they did (a call, an enquiry, a purchase) and controlled by a cooldown, quiet hours and an excluded list. Calendar-driven blasts are what annoy people; a message that follows their own call is expected.
Do I need the WhatsApp Business API to send automatic messages?
Not for one-to-one follow-ups: a dialer can open WhatsApp on your own number with the message prepared after each call. You need the official API for fully hands-free sending, bulk campaigns to hundreds of numbers with delivered and read reports, and message templates. RMDialer works both ways and connects to the API from Meta or any provider.
How much does the WhatsApp Business API cost in India?
Meta charges per conversation, roughly ₹0.11 to ₹0.80 depending on the category (marketing costs the most, service conversations started by the customer are free within a window). Providers add a platform fee. RMDialer does not charge extra to connect an API you already have; you pay Meta or your provider directly for messages.
How to send a WhatsApp message automatically after a call?
Use a dialer with auto WhatsApp: set a message once per call type (missed, incoming, outgoing) and per lead status, and the app sends it the moment the call ends, personalised with the customer's name. From the user's own number it opens WhatsApp with the message ready; through the WhatsApp Business API it sends with zero taps.
How to send bulk WhatsApp messages without getting banned?
Send to people who know you and have opted in, personalise with the name, keep to a few hundred a day from a normal number with gaps between messages, and stop sending to anyone who does not reply or asks you to stop. For larger volumes use the official WhatsApp Business API with approved templates, which cannot be banned for volume and gives delivery reports.
What is a WhatsApp CRM?
A WhatsApp CRM keeps customer chats next to the customer record, so a conversation, its call history, lead status and follow-ups are one file instead of a chat on someone's phone. Built into a dialer, it lets a team reply from the same app they call from, send media and templates, see read receipts, and keep the chat when the employee leaves.
Does bulk WhatsApp from my own number work without an API?
Yes, one message at a time from your phone: the app prepares each message with the name filled in and hands it to WhatsApp, and you tap send. It is safe for lists of a few hundred known contacts. For thousands of numbers, or for reports of delivered, read and replied, the WhatsApp Business API route is the right one.
What is an auto dialer app?
An auto dialer app calls a list of phone numbers one after another so the caller never types a number. On Android, an app like RMDialer runs the session on the phone itself using the SIM already in it: you pick a list from Excel, a Google Sheet, an API or assigned leads, press start, and the app dials each number in turn while you mark the outcome between calls.
What is a telecalling CRM?
A telecalling CRM is customer software built around phone calls: the lead list, the dialer, the call outcome and the follow-up live in one place. The mobile kind, such as RMDialer, replaces the Android phone app on each rep's handset so every call automatically becomes a record with a status, a remark and the next follow-up, and the manager sees the whole team on a web dashboard.
What is the difference between telecalling software and a CRM?
Telecalling software is built to make and track calls (dialing lists, call logs, per-caller reports). A CRM is built to hold customer records and pipeline stages. Most Indian sales teams need both at once, which is why a telecalling CRM combines them: the call itself creates and updates the customer record, so nobody types into a separate system after the call.
What is a CRM dialer?
A CRM dialer is a single app where the dialer and the customer record are the same thing: the call screen shows the lead, and ending the call updates it. It differs from a CRM with "dialer integration", which is two products joined by a sync. RMDialer is a CRM dialer for Android that runs on the user's own SIM.
What is a business dialer app?
A business dialer app replaces the default phone app on an Android phone with one made for selling: caller ID from your own leads, the last remark on screen when a customer rings, two-tap status and follow-up after each call, automatic WhatsApp, and a call log that filters by lead status. It is a personal CRM for one owner and a team system when several people use it.
Does RMDialer work on iPhone?
No. RMDialer is an Android app because iOS does not let a third-party app replace the phone dialer, read the call log or place calls automatically. It supports Android 8.0 and above. The owner's Web CRM works in any browser, including Safari on a Mac or iPhone.
Which languages does the RMDialer app support?
The app itself runs in 40 languages, including Hindi, Bengali, Tamil, Telugu, Marathi, Gujarati, Kannada, Malayalam, Punjabi, Odia and Assamese for India, and Arabic, Bahasa, Tagalog, Swahili, Portuguese, Spanish, French and others for teams abroad. Each user picks their own language on their own phone.

“Telecaller app for Android that my staff actually use. Enquiry list is assigned to each telecaller, the auto dialer calls it from their own SIM, and test ride bookings come to me live. Punjabi interface for the girls at the desk. Price is honest, everything included, no per-user surprises.”
“We needed an auto dialer app that works on our own MTN and Airtel lines, not a call centre subscription in dollars. RMDialer runs on the phones my agents already have, dials the enquiry list, and the WhatsApp follow-up goes out after every call. Works even when the network drops and syncs later.”

“We looked for telecalling software for a nine-person loan team and every quote came with cloud seats and per-minute bills. RMDialer telecalling software runs on the callers' own Jio SIMs: the lead list dials itself, the remark goes on the number, and I get dials, connects and talk time per caller every evening. Cost is one flat price per user.”

“Earlier I was dialling 80 to 100 portal leads a day by hand from Excel. With RMDialer auto dialer app I import the sheet, press start and it calls one by one from my own Jio SIM. Between calls I mark Interested or Site visit in two taps and the follow-up rings me on time. Closed 3 flats last month from leads I would have forgotten.”
“We tried two telecalling CRM software before this and my counsellors stopped filling them within a week. RMDialer is the phone app itself, so every admission enquiry gets logged whether they like it or not. The auto WhatsApp after call sends the fee structure by itself. I see all 4 counsellors' calls on the web CRM every evening.”
