WhatsApp notifications
that people actually read.
A transactional email is opened in about one in five cases - and often after the fact, when it doesn't land in spam. A WhatsApp notification, on the other hand, is read at over 90% and most often within minutes. Order confirmation, delivery tracking, appointment reminder, alert: send them via API, from your normal WhatsApp account.
The context
What is a transactional WhatsApp notification?
A transactional WhatsApp notification is a message triggered by a specific event - the equivalent of the WhatsApp Business API's "utility templates," but without Meta's prior approval.
The difference with email isn't a matter of taste, but of numbers. Transactional emails often cap out around 20 to 25% open rate, arrive late, and a spam filter or a "Promotions" tab is enough to make them invisible. A WhatsApp notification arrives where your customer is already looking several times an hour, and shows read rates above 90%, usually within minutes of sending.
The use cases are always the same, because they're the ones that matter: the order confirmation that reassures right after payment, the delivery tracking that avoids ten calls to support, the appointment reminder that reduces no-shows, and the alert - security, stock, deadline - that needs to be seen right away. An automated WhatsApp message turns each of these moments into an opened notification.
The official WhatsApp Business API offers these messages via "utility templates," but requires a verified business account, approval of each template, and per-conversation billing. For an SME, a store, or a service that simply wants to send a WhatsApp order confirmation or a reliable reminder, this friction is disproportionate - and that's exactly what our approach removes.
Comparison
Email, SMS, and official WhatsApp API vs Unlimited Messaging
The same goal - a notification your customer sees and reads - but very different constraints depending on the channel. Here, line by line, is what email, SMS, and the official WhatsApp Business API impose, and how our alternative frees you from it.

|---|---|---|
| Open rate | Email ~20%, variable for SMS | Read rate above 90% |
| Time to read | Hours, or never (spam) | A few minutes |
| Utility templates to approve | Meta approval required | No template, free text |
| Business account required | Verified Meta Business account | Your normal WhatsApp account |
| Pricing | Per conversation or per segment | Flat monthly price, unlimited |
| Media (PDF / images) | Limited in SMS, heavy in email | Native PDFs, images, and videos |
| Status webhooks | Depends on the provider | Delivered / read / reply in JSON |
| Setup | Days to weeks (verification) | A few minutes |
