A dialer with WhatsApp is a calling app that sends a chosen WhatsApp message to the customer straight after each call ends. Most calls end with an intention to send something. The catalogue, the price list, the location, the payment link. Later arrives, twenty calls have happened, and it never went.

The short version
A dialer with WhatsApp fires off the follow-up message by itself once a call finishes, so nobody has to copy the number, change apps or remember later.
RMDialer uses Meta's official WhatsApp Business API for these sends, with separate approved templates for missed, outgoing and incoming calls and quiet hours across them.
The price list or location goes out even on the twentieth call of the day.
A missed call and an interested lead each get their own wording.
Official API sending avoids the ban that hits WhatsApp Web automation.
Campaigns and replies sit beside the customer record in the same app.
RMDialer is a dialer with WhatsApp built in, for Android. A dialer with WhatsApp built in sends the follow-up message automatically when a call ends, rather than leaving the caller to copy a number, switch apps and type it later, which is the step that quietly does not happen once the day gets busy. RMDialer sends on the official WhatsApp Business API from Meta, which matters more than it sounds: messages sent by automating a personal WhatsApp account violate Meta’s terms and get numbers banned, usually at the worst moment. Rules can differ by what happened on the call, so a missed call, a connected call and a lead marked interested each get their own message, with the customer’s own details merged in. Bulk campaigns run from the same app and replies land beside the customer record rather than in a separate inbox.

This is the most consequential thing on the page, and the part the cheaper tools are quiet about.
There are two ways to send WhatsApp automatically. One is the official WhatsApp Business Platform, where Meta approves your templates, charges per conversation, and the number is a registered business sender. The other is software that drives a normal WhatsApp account, usually by automating WhatsApp Web, which is cheaper, needs no approval, and violates Meta’s terms.
The second works until it does not. Meta detects automation patterns and bans numbers, and the ban usually lands once volume is high enough to matter, taking the business number and its message history with it. Recovering it is difficult and often impossible, and customers who had a conversation thread with you simply lose it.
RMDialer sends on the official API. That means template approval before a message can be automated, and a per-conversation charge from Meta which is passed through at cost rather than marked up. It is slower to set up and it is the reason the number survives. Anyone comparing on price alone should make sure they are comparing the same thing.
Two rules govern what a business can send on the official API, and understanding them explains most of the interface.
Outside an open conversation, you may only send a pre-approved template. Meta reviews the wording, which is why the screen above separates templates for manual sending from approved Meta API templates. Approval usually takes minutes to hours, and templates are rejected for being vague, misleading or too promotional for their stated category.
Once a customer replies, a 24-hour service window opens and you can send freely within it. This is why the after-call message matters so much: it opens a conversation while the call is still fresh, and if the customer replies at all, the rest of the follow-up becomes ordinary messaging.
The practical advice is to write fewer templates than you think you need and make them specific. A vague "thanks for your time" template gets approved and ignored. One that names the product discussed and attaches the price list gets replies, which is the outcome that actually matters.
Automatic messaging fails in a specific and avoidable way: it keeps working when it should have stopped.
Three controls prevent almost all of it. Quiet hours hold automatic sends outside working times, so a reminder due at 11pm does not wake a customer. An excluded contacts list means specific numbers never receive an automatic message, which every business needs for its own staff, its suppliers and the customer who asked to be left alone. And stop conditions on a follow-up series end it the moment someone replies or takes a call.
The sent history is the fourth, and it is the one people forget to look at. It records every automatic message sent, skipped or failed, which is how you discover that a template has been silently failing for a week rather than finding out from a customer.
Restraint is also commercially sensible here. Meta charges per conversation, so messages nobody wanted cost money as well as goodwill.
This is a dialer with WhatsApp attached, not a full customer messaging platform. For a shared team inbox, chatbots, catalogues, payments and broadcast campaigns at scale, that is the WhatsApp API platform rather than this.
Meta charges per conversation and those charges are yours, passed through at cost. Automatic messaging on a large list has a real running cost that should be modelled before switching it on.
Template approval is Meta’s decision, not ours. A template can be rejected and there is no appeal beyond rewriting it.
And it cannot message someone who has blocked you, or who never had a conversation and for whom you have no approved template. The channel has rules, and a tool that claims otherwise is the unofficial kind.
| Feature | Official Business API (RMDialer) | Automated personal account |
|---|---|---|
| Permitted by Meta | Yes, it is their platform | No, it breaches the terms |
| Risk to your number | None from sending itself | Ban, usually once volume grows |
| Message approval | Templates reviewed by Meta | None |
| Cost | Per conversation, passed through at cost | Software fee only |
| Delivery reporting | Sent, delivered, read | Unreliable |
| Green tick eligibility | Possible | No |
| Survives a WhatsApp update | Yes | Breaks regularly |
| Setup time | Verification, then template approval | Minutes |
Meta’s per-conversation charges are set by Meta and vary by country and conversation category. WappBlaster passes them through at cost rather than marking them up.

The mechanics are covered in how an after-call WhatsApp actually works, sending a brochure as soon as the call drops and writing a better after-call message.
Straight answers about Dialer with WhatsApp.
Yes. RMDialer sends an approved template on the official WhatsApp Business API the moment a call ends, with the customer’s details filled in and the rule varying by call outcome.
Link to this answerNot on the official Business API with approved templates and opted-in recipients. What breaches policy is unofficial tooling that automates the consumer app, and that is what gets numbers banned.
Link to this answerFor marketing templates, yes. A customer who called you has shown intent but that is not blanket marketing consent, so collect it explicitly and keep the after-call message relevant to what they rang about.
Link to this answerThey are two separate products. Auto WhatsApp After Call is a dedicated app for that one job and does not change how you dial. RMDialer is a dialer and CRM that has after-call WhatsApp as one of its features.
Link to this answerThe dialer with WhatsApp genuinely built in is RMDialer: a business dialer and telecalling CRM where the follow-up, on the official Business API, sends itself when the call ends. Most dialers either lack WhatsApp entirely or automate the consumer app unofficially, which risks the number.
Link to this answerYes. Attach the digital catalogue link to the after-call template and every answered enquiry call delivers it without the caller doing anything. Wholesalers run rate lists the same way, and clinics send location and prep instructions.
Link to this answerThe reply lands in the in-app inbox beside that customer’s record, so whoever handles it sees the call history and the lead stage together. Replies do not vanish into one person’s phone.
Link to this answerRules key off the call outcome and can include the caller’s details, so each rep’s follow-up carries their own name and number while the templates stay company-approved.
Link to this answerMeta charges its per-message rate for business-initiated template messages, passed through at cost. The RMDialer plan itself does not meter messages; the ₹1908 ($29) per user per year covers the software including the WhatsApp automation.
Link to this answerYes. The same app sends bulk campaigns on the official API, personalised per contact, to segments built from your lead fields, and campaign replies land in the same inbox as after-call replies.
Link to this answerNot on the official Business API with approved templates, which is how RMDialer sends. The banned-number stories come from unofficial tools that script the consumer app; the official route is the reason this feature can exist safely.
Link to this answerYes, and it is one of the highest-value rules: a missed enquiry call can immediately receive "sorry we missed you" with a callback promise and the catalogue, so the enquiry survives until the callback happens.
Link to this answerThe Business API number is registered with Meta, and the practical setup is one company WhatsApp number for automation while callers dial from their own SIMs. RMDialer connects the two so the call and the message meet on the same customer record.
