Email gets ignored and SMS gets more expensive every year. Meanwhile your players already live inside one app — WhatsApp. For casino marketing teams, it has become the highest-engagement channel for reactivation offers, free-spin drops, and event invites. This guide covers how it works, what the rules are, and how to run it without torching your number.
Why WhatsApp beats email and SMS for casinos
WhatsApp messages tend to be opened far more often than marketing email, and unlike SMS you can send rich content — images, buttons, and QR codes players can redeem on the floor. For a casino, that means a free-spins offer lands as a tappable message rather than a 160-character text the player has to decipher.
- Direct line: messages arrive in the same inbox as family and friends, not a promotions folder.
- Rich media: send branded images, redemption QR codes, and quick-reply buttons.
- Two-way: players can reply, opt out, or claim — and you capture intent.
The two ways to send: Cloud API vs. your own number
There are two technical routes. Meta's WhatsApp Business Cloud API charges per conversation and requires template approval. The alternative is sending from your own linked WhatsApp Business number — no per-message fee, but you must respect sending limits and warm-up so the number stays healthy. CasinoComm uses the second model so your cost is flat and predictable.
Opt-in is non-negotiable
Only message players who have opted in. That is both a platform rule and, in most jurisdictions, a legal one. Capture consent at sign-up, at the desk, or via a first "reply YES" message — and honour STOP keywords instantly. See How to message players without getting banned for the operational detail.
Warm-up: the step everyone skips
A brand-new number that suddenly sends 5,000 messages looks exactly like spam. Healthy numbers ramp gradually over days — a warm-up ladder that raises the daily cap as the number builds reputation. A good platform enforces this for you rather than leaving it to chance.
What it costs
With the Cloud API you pay per conversation, which varies by country and category. With a linked-number platform like CasinoComm, you pay a flat €250/month for 10,000 messages on your own number — no per-message fees, no surprises.
