RMDialer is bulk WhatsApp software inside the dialer: pick any list you already own, leads, call log, clients or pasted numbers, choose a template, and send from your own phone or through your API.
From your phone or your API · Duplicates removed · Reports beyond "sent"
Your own SIM, no virtual number · Android and iPhone apps + Web CRM in one plan · No card for the trial
Short answer
The safe way to send bulk WhatsApp messages to customers is the official WhatsApp Business API with approved templates. RMDialer sends campaigns that way. You pick a contact list, choose a template, fill the per-contact variables, and send. Delivery, read and failure counts come back per message, so a campaign is measurable instead of guesswork. Using the official API is the part that decides whether this is safe: tools that drive WhatsApp Web or a modified app break WhatsApp terms of service, and numbers used that way get banned in waves, which costs you the number every customer has saved. Recipients can come from leads, saved contacts, CRM segments or call-log numbers, and are de-duplicated per person before anything sends, so nobody receives the same campaign twice. Anyone who has asked not to be contacted stays excluded no matter which list a campaign is built from.
Key takeaways
Leads, Call log, WhatsApp CRM, Clients, Paste numbers, or Lead sources. Then filter by status, tag, or product and select all.
Pick an approved template, fill the variables with {name}, {city}, {company} tokens, and choose One by one (your phone) or Server campaign (Meta API). Test one first.
Sent, Delivered, Read, Replied, Failed, with every recipient listed. Pull to refresh as WhatsApp reports back.
| Part | What it does |
|---|---|
| Six ways to pick who gets it | Leads · Call log · WhatsApp CRM contacts · Clients · Paste numbers · Lead sources (a Google Sheet or API). The people are already in the app. You never build a list twice. |
| Bulk WhatsApp to your leads | Filter by status (New, Interested, Won, Lost, your own), by tag (#Import 10 Jul, #demo), or by product, then select all or hand-pick. "508 selected" and you are ready. |
| Bulk WhatsApp to your call log | Everyone you actually spoke to is already a ready-made list: no export, no CRM entry, no copy-paste. The numbers are already on your phone. |
| Bulk WhatsApp to WhatsApp CRM contacts | Thousands of people who already messaged your business number are a ready-made, warm list. |
| Bulk WhatsApp from a Google Sheet | Point Lead sources at a sheet or API and broadcast to the fresh rows it pulls in, so your ad leads get a message the same day they arrive. |
| Bulk WhatsApp by pasting numbers | Got a list on paper, in Excel, or in a WhatsApp group? Paste the numbers, the app cleans the list, removes duplicates and sends. Nothing needs to become a lead first. |
| Two ways to send | One by one from your own phone (safe and slow, no API needed) or Server campaign through the Meta API (fast and bulk). Start without an API and upgrade when volume demands it. |
| Personalized, not copy-pasted | Fill template variables with tokens like {name}, {city}, {company}, {interest}, {email}, {phone}, so 500 people each get a message that reads like it was written for them. |
| Test one before you send 508 | Send a single test to yourself, check how it looks, then hit Send. No blast goes out on a guess. |
| Reports that go past "sent" | Sent, Delivered, Read, Replied, Failed, plus the full recipient list, updating as WhatsApp reports back. You finally know what the campaign actually did. |
Real businesses, real numbers: how owners and sales teams across India and 12+ countries use RMDialer every day.
“Order calling to 350 chemists every week. The list auto dials from each MR's own SIM, the order remark goes on the chemist's number, and I see calls and talk time per MR every evening on the web. Bulk WhatsApp for the new scheme went to the whole list from the call log in one go.”
“Rebooking is our revenue. Every client who visits gets a reminder call 4 weeks later, set from the after-call screen in two taps, and the festive offer goes as a WhatsApp broadcast to the call log. My receptionist learned the app in an hour. The backup meant nothing was lost when her phone broke.”
“Lead management app for our admission counsellors across 3 branches. Every parent enquiry has a status, a remark and a follow-up, and the branch heads see their own funnel. The bulk WhatsApp for the open-day invite went to 900 parents from the app with delivered and read counts. Admissions were up 18% this year.”
“I am a one-person business. RMDialer is the business dialer app on my own phone: every customer call becomes a record, the wedding date is the reminder, and the new collection goes out as a WhatsApp broadcast to my 600 customers from the call log. Paid clients tab shows who has paid and who has balance due.”
“Staff attendance with selfie and location, inside the same dialer our supervisors already use for client calls. Punch in only works within the site geofence and needs a live selfie, so proxy attendance stopped. The monthly report exports for payroll. One app, two problems solved.”
“Multilingual team, so a CRM with English, Malay and Chinese interfaces mattered. The auto dialer runs our launch lists on the agents' own Maxis SIMs and the manager sees every call and remark live. We compared three cloud call centre tools; this cost a fraction and needed no virtual numbers.”

The app is split in two: the dialer and everything needed to place, take and review calls costs nothing permanently, and the features that remember customers or move data between phones and people are what a plan pays for.

Any list already in the app: your leads (filtered by status, tag, or product), your call log, your WhatsApp CRM contacts, your paid clients, a Google Sheet or API connected as a lead source, or numbers you simply paste in.
Yes. Choose "One by one" and messages go from your own phone and number, safe and slow. The Meta API (Server campaign) is only needed for fast, high-volume sending.
Yes. Paste numbers from anywhere (paper, Excel, a WhatsApp group) and send. The app cleans the list and removes duplicate numbers. Nothing has to become a lead first.
Yes. You can pick the call log itself as your list, so everyone you spoke to can get the offer without you exporting anything.
Filters: lead status (including your custom statuses), tags like #Import 10 Jul, and products. Select all, or hand-pick from the list. The header always shows how many are selected.
The template is the same. The content is not. Variables fill from each lead ({name}, {city}, {company}, {interest}, {email}, {phone}), so every message reads personal.
No. Server campaigns run through the official Meta WhatsApp Business API using approved templates, which is the compliant way to message at scale. Message only people who consented to hear from you.
Yes. "Test one" sends the template to a single number first. Only then do you hit Send.
Sent, Delivered, Read, Replied, and Failed counts, plus every recipient number. Delivery updates arrive over time (seconds to about half an hour), and pull-to-refresh re-checks.
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.
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.
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.
Marking a lead as lost with a reason, and keeping every lost lead in one list instead of letting it disappear. Lost leads are the cheapest sales you can make later: a win-back call or WhatsApp campaign to last quarter's lost list costs nothing to source and converts better than cold numbers.
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.
Lead automation
Leads from 15+ platforms → auto-assigned round robin → auto dialed → updated. On its own.
Facebook, JustDial, IndiaMART, portals, sheets, Excel: every lead gets an owner and a place on a calling list, then reports its own outcome.
