Which WhatsApp CRM Actually Works for a Singapore Property Agent?

A WhatsApp CRM turns chat threads into a working record: who this person is, what they want, what you last said, when to follow up.

The important split is in how it sends:

For a solo property agent, click-to-chat is very often sufficient, and the industry rarely says so because there is no revenue in it. You are the only person replying, your volume is human-scale, and pressing send yourself takes a second.

You need the official platform when you want messages to go out without you — an auto-reply to a new enquiry at 2am, or one broadcast reaching a few hundred past clients. Those are real capabilities. They are also where the second cost appears.

Everything else on this page follows from one rule, so it comes next.

This is the rule that shapes the whole category, and understanding it will save you money and disappointment.

Inside the window. A client writes to you. For the next 24 hours you can send whatever you like, in whatever words you choose, free. SleekFlow states it plainly on its own pricing page: customers message you first, reply for free within 24 hours.

Outside the window. You can no longer send a free-form message. You may only send a message template you submitted to Meta in advance and that Meta approved — and that conversation is billed by Meta, separately from whatever you pay for software. respond.io says so directly in its pricing FAQ: WhatsApp fees are not included in any subscription, because Meta charges them based on your usage.

Four consequences that explain things you have probably noticed:

"Unlimited broadcasts" is never unlimited. Unlimited by the software, billed by Meta.

Speed of reply is worth real money. A follow-up sent the same day costs nothing. The same message on Thursday costs money and has to be pre-approved.

Templates take time. They must be written and submitted before you need them, so the day you want to send something is the wrong day to start.

Approval is not automatic. Meta reviews templates against its own rules, and a badly written one gets rejected.

The 24-hour window is the most valuable free thing in your business. Almost every agent lets it close.

Check the current charging model on Meta's own pricing page — it has changed more than once and will change again.

This is the question agents ask least often and should ask first, because your number is your business.

There are two ways a tool can send WhatsApp messages for you.

Officially, through the WhatsApp Business Platform, with the vendor operating as an approved provider. Your number is registered with Meta for business messaging, the sending is sanctioned, and templates go through Meta's own approval.

Unofficially, by driving WhatsApp Web or a logged-in phone in the background and pretending to be you typing. These tools exist, they are cheap, and they breach Meta's terms of service. Numbers using them get restricted or banned, and there is no appeal worth having when the account is your entire client list.

The distinction is easy to check, and the authority is Meta's own terms rather than any vendor's marketing. Providers operating officially say so prominently, because it is their main competitive advantage. Tools that avoid the subject, or that ask you to scan a QR code to link a session they then automate in the background, are telling you what they are.

Two questions before you connect a number to anything. Are you an approved provider on the WhatsApp Business Platform? And does my number stay mine if I leave — can I take it back and use it normally?

A cheap tool that costs you your number is the most expensive software you will ever buy.

Three products a Singapore agent will keep encountering, with prices read off each vendor's own page on 20 August 2026:

Read the last column against the first. Privyr's WhatsApp Auto-Responder, Campaigns, Automated Sequences and Contact Import are all listed as paid add-ons on top of its paid plans — so the cheapest entry to this table does not include the WhatsApp automation you might assume you were buying. The full breakdown is here.

The two team products are excellent and are solving a problem a solo agent does not have — routing one queue among several people. Their pricing model gives it away: billed per workspace with users included.

And on all four, Meta's charges are separate. When you compare monthly prices you are comparing software, not messaging.

Connect your number to any product here and something real improves: conversations become searchable, contacts stop living only in your head, and replying gets faster. That is worth having.

What none of it changes is the harder half. On the Monday your list shows fourteen people overdue, the CRM can tell you they are overdue and can draft you a message — but the message is built from what you typed about them, because that is all the system holds. You get a well-organised, promptly delivered "just checking in", which is the message clients ignore.

⭐ PropKaki is the market-aware one, and that is the whole difference. For each person it checks what has actually changed since you last contacted them — new listings on their brief, transactions in the block they are selling, competing supply, area movement, and the clocks running down on what they own. The draft is written from those findings, in your voice, and if nothing has changed it produces no message at all.

It sends through your own WhatsApp business number using your own Meta-approved templates, with no PropKaki branding a client can see, and it treats the 24-hour window as a rule rather than an error: in-window sends go free-form, cold ones use an approved template, and where neither is available it tells you why instead of failing quietly.

The scope, plainly: it does not score or rank your leads, so it will not tell you who to message first. No mobile app, no image reading, and the market check runs when you press it rather than overnight. It is free to agents verified against the CEA public register.

How it works · ask for a demo on WhatsApp

Do you need messages to send without you? If the honest answer is no — you are one person, you reply yourself, and you do not broadcast — then click-to-chat is enough and you should not be paying for the official platform at all. That decision alone can save a few hundred dollars a year.

Does it connect officially? Non-negotiable if the answer above was yes. Ask the vendor directly, and treat evasion as an answer.

What leaves with you? Two sub-questions, and most agents ask neither until it is too late: can you export the contacts in full, and does the conversation history come with them? A name without its context is a name you will not call.

Then, and only then, the ordinary comparisons — price, interface, whether it knows anything about property.

One pattern worth naming, because it is the most common good outcome: many agents end up with their agency's app for agency work, and one modest personal tool for the relationships they intend to keep. The second one is the one that has to be portable.

No, for the simpler kind. Many CRMs integrate by generating a link that opens WhatsApp on your phone or desktop with the message already typed — you read it and press send. There is no registration, no approval and no Meta charge, because as far as WhatsApp is concerned it is just you messaging someone.

You need the WhatsApp Business Platform — commonly called the API — when messages must go out on their own: automatic replies to new enquiries, broadcasts, scheduled sequences. That means registering your number for business messaging through an approved provider, getting templates approved, and paying Meta per conversation on top of your software.

For most solo property agents the first is enough, and the second is a cost worth deferring until you can name the thing it will do for you.

One practical note: a number registered on the Business Platform behaves differently from an ordinary WhatsApp Business app account. Ask any vendor what happens to your number if you stop using them.

Meta charges on a conversation basis rather than per message, and the rate depends on where the recipient is and what category the conversation falls into — for example, whether it is a service reply, a utility notification or marketing. Rates have been restructured more than once, so any figure quoted in an article ages badly.

What matters practically is the shape of it:

• Replying inside the 24-hour window after a client messages you: free.
• Starting a conversation outside that window: charged, and it must use a pre-approved template.
• The charge is Meta's, not your software vendor's, and it appears on top of any subscription. respond.io and SleekFlow both state this on their own pricing pages.

Check the current rate card on Meta's WhatsApp Business Platform pricing page before planning any broadcast, and be aware that some providers add their own margin on top of Meta's rate.

The mechanics are straightforward: an official-platform provider, approved templates, and a list. Every recipient is a billed conversation.

Three things to weigh before you do it.

The regulatory question. Marketing messages sent to Singapore telephone numbers engage the Do Not Call obligations, and how you obtained and use the personal data engages the Personal Data Protection Act. Those duties sit with you, not with the software. Check the current rules with the Do Not Call Registry and the PDPC.

The deliverability question. Recipients who did not expect the message report it, and enough reports affect your number's quality rating and sending limits.

The commercial question. A message written for everyone is read as marketing by everyone. In a relationship business, the version that works is the message only one person could have received.

A reasonable middle path: broadcast rarely, to people who genuinely expect to hear from you, about something genuinely specific to their situation — and treat anything else as an expense with a downside.

What we did. On 20 August 2026 we opened the public pricing pages of Privyr, respond.io and SleekFlow's Singapore site and recorded plan names, prices, currencies and stated limits verbatim, including Privyr's listing of its WhatsApp features as paid add-ons and respond.io's statement that WhatsApp fees are not included in any subscription.

What we deliberately did not do. We did not quote a per-conversation rate for Meta's charges. The rate card varies by country and conversation category and has been restructured more than once; a number printed here would mislead. The mechanism — free replies inside the 24-hour window, approved templates and charges outside it — is stable, so that is what we describe. Check the current rates on Meta's own page.

On the ban question. The distinction drawn between official WhatsApp Business Platform providers and unofficial tools that automate a logged-in session reflects Meta's own terms. We do not name any specific unofficial tool, and we did not test any.

On PropKaki. This page is published by PropKaki. Its limitations are stated alongside its capabilities — no lead scoring, no mobile app, no reading of images, no scheduled scanning, consent and Do Not Call recorded rather than enforced, and verified CEA agents only. No claims are made about agent numbers, message volumes, delivery rates or conversion.

Regulatory points are as of 2026 and change. Verify obligations with the PDPC, the Do Not Call Registry and CEA. This is not legal advice, and compliance is the agent's own responsibility whichever software sends the message.
