WhatsApp Business Platform

Reach every customer where they already reply

Resalian sends your promotions to your whole customer list over WhatsApp, keeps every reply in one shared inbox, and tells you which customers are actually worth messaging again.

Open the dashboard See how it works

Built on Meta's official WhatsApp Business Platform — not an unofficial automation tool that gets your number banned.

The inbox — every conversation, with the 24-hour reply window built in.

Email gets ignored. WhatsApp gets read.

Your customers already have WhatsApp open. Promotions land where they look, and replies come back to you instead of into an unread folder.

One number, your whole team

Stop passing a phone around. Everyone answers from the same business number, sees the same history, and nothing gets lost when someone is off.

Know who is worth messaging

Not every customer deserves the same promo. See who reads, who replies and who spends — then send to just that group.

What you get

Everything needed to run WhatsApp properly

Available now

Bulk campaigns from a spreadsheet

Upload your customer list, pick an approved template, map each {{1}} to a column, and send. Resalian shows you exactly how many numbers are valid before anything goes out.

  • Personalised for every recipient — first name, order number, discount code, straight from your file.
  • Paced, not blasted — a controlled send rate protects your number's quality rating with Meta.
  • Quiet hours — a long campaign pauses overnight and resumes in the morning, in your timezone.
  • Pause, resume, cancel — mid-send, without losing your place or messaging anyone twice.
  • Opt-outs handled for you — anyone who replies STOP is removed from every future campaign automatically.

An inbox that works like WhatsApp

Because your team already knows how to use it. Conversations on the left, the chat in the middle, the customer on the right. No training required.

  • The 24-hour rule, made obvious — WhatsApp only allows free replies within 24 hours of a customer's message. We show a live countdown and switch to templates when it closes, instead of letting you hit an error.
  • Delivery ticks you can trust — sent, delivered and read, straight from Meta.
  • Campaign context — see which promotion someone received before you reply to them.
Free replies allowed for another 6h 20m
The composer tracks the reply window so your team never has to.

Segments built on real behaviour

Resalian scores every customer on how they engage — read rate, replies, how recently they answered. Connect your order data and that becomes full RFM: recency, frequency and spend, with churn risk on top.

  • Champions, At risk, Hibernating — the standard RFM groups, calculated by ranking your customers against each other rather than against a number someone made up.
  • Send to a segment in two clicks — "Champions who haven't ordered in 60 days" becomes a campaign.
  • Always evaluated fresh — 60 days means 60 days from today, never from whenever the segment was saved.

Engagement scoring works from day one. Spend-based segments need order totals sent to our API — no customer list required.

Getting started

Live in an afternoon

  1. Connect your WhatsApp number

    A guided setup in the dashboard walks through Meta's requirements and checks each step actually worked — no runbook, no consultant.

  2. Get a template approved

    Write your promotion, submit it to Meta from Resalian, and track its approval status in the dashboard.

  3. Upload your list

    Drop in a CSV. It is read in your browser and checked for valid numbers before anything is uploaded.

  4. Send, then watch

    Delivery, reads and replies update live. Replies land in the inbox for your team to answer.

A test number before you touch production

Every account gets separate test and live environments. Try a campaign end to end without spending money or risking your real number's reputation — and an API key issued for test can never reach production.

Your own systems can send too

A documented REST API sends order confirmations, delivery codes and reminders straight from your existing software, with webhooks pushing delivery updates back to you.

Your data stays yours

You don't have to hand over your customer list

Most messaging platforms require you to upload your entire customer database before you can send anything. We think that's a fair thing to object to — so Resalian gives you three levels of control.

Keep the list

The default. Upload once, reuse your audience, see the full history of who received what.

Erase after each campaign

Phone numbers are deleted the moment a campaign finishes — not on a nightly job. Delivery statistics and opt-outs keep working, because those are stored as one-way hashes.

Never send it at all

Keep the list on your own servers. Resalian requests one page of recipients at a time while the campaign runs, sends to them, and keeps nothing but a hash.

  • Automatic deletion — set a retention period and message history is scrubbed on schedule, with a log you can show an auditor.
  • Opt-outs are permanent — kept as hashes so someone who said STOP stays unsubscribed even after their number is erased.
  • Encrypted credentials — your WhatsApp access tokens are encrypted at rest and never displayed again.
  • You are the controller — Resalian processes customer data on your instructions, and only for delivering your messages.

Where this is going

WhatsApp today. Facebook and Instagram next.

Resalian starts with WhatsApp because that is where replies actually happen. The same campaign builder, the same audiences and the same segments are being extended to Meta's other channels, so one promotion can run across all of them and report back in one place.

Available now

WhatsApp Business Platform

Bulk campaigns, shared inbox, templates, segments, delivery reporting and a full REST API.

On the roadmap

Facebook & Instagram campaigns

Run the same promotion to the same audience across Meta's channels, and bring Messenger and Instagram Direct conversations into the same inbox.

On the roadmap

Cross-channel reporting

One view of what a campaign did everywhere it ran, tied back to the same customer segments.

Stated plainly: Facebook and Instagram support is in development and is not available today. Nothing on this page is sold on the basis of a feature that does not yet exist — if you need those channels now, tell us and we will give you an honest timeline rather than a sales answer.

Who builds this

Tech Serenity IT

Resalian is designed, built, owned and operated by Tech Serenity IT — a software company building practical business tools on modern cloud infrastructure.

Resalian runs on Cloudflare's global network, which means your dashboard and your API calls are served close to wherever you and your customers are. It is a product we run ourselves, not software resold from someone else, so when something needs fixing there is no vendor in between.
