*Open rate
Calculated using charles data across all customers and universes – excluding small campaigns with <500 messages delivered. Data is from the time period Dec 23 - Jun 24.

*ROAS
Average ROAS per month from Dec 23 to May 24 from all charles customers with enabled revenue tracking. And taking into account the marketing conversation Meta fees for Germany = €0.1131

At charles, we calculate ROAS for WhatsApp as a channel by looking at the revenue generated per WhatsApp conversation and how much a conversation costs in Meta fees – not taking into account the charles platform fees. This metric helps gauge how effective a WhatsApp marketing campaign has been for a business.

How much does WhatsApp cost?

Small businesses can use the WhatsApp Business app, which is free.

Medium to large businesses usually use the WhatsApp Business Platform (API), which offers greater functionality and scalability. To use this, you need a platform from a WhatsApp Solution Partner like charles or a Tech Provider – or you can build the solution yourself.

To use WhatsApp you need to consider two types of costs:
1. Meta fees charging a cost per conversation (see WhatsApp costs for your country)
2. Fees for your platform provider

 

Remember: WhatsApp is associated with additional costs compared to channels such as email.

For more, see our guide to WhatsApp costs.

How do I get started?

If you're a small business communicating with up to 256 contacts at a time, you can download the free WhatsApp Business app and get going straight away on your phone (or simple web version).

 

If you're a medium to large business looking to scale WhatsApp across teams and countries (like our customers), you'll likely want to use a software platform using the WhatsApp Business Platform (API). You have 3 options to access a software platform:
1. Partner with an official WhatsApp Solution Partner like charles
2. Go to a Tech Provider
3. Build the software yourself

 

Solution Partners like us offer a user interface so brands can use the functionality of the API like automation, unlimited users, unlimited subscribers and audience segmentation.

 

To get started, first, you'll need to find the right partner for your business – offering the right use cases, functionality and level of support.

 

Then you'll need to get onboarded and learn about how the platform works, as well as get to know WhatsApp marketing best practices.

Can I stay GDPR compliant? 

Companies can use WhatsApp to communicate with their customers and subscribers in a GDPR-compliant manner. The 2 most important areas to consider are:

1. Data consent (double opt-in, unsubscribe...)
2. Data management (sharing and deleting customer information, data stored in the EU...)

At charles, we support you with guidance on GPDR compliance.

See more in: WhatsApp and GDPR: the basics for businesses.

What about WhatsApp Channels?

WhatsApp Channels is a recent addition to the WhatsApp Business offering. It enables people and organizations to broadcast messages to large amounts of people for free and is now available in many countries across the world.

It's a useful tool for certain use cases but doesn't offer rich analytics or audience segmentation. In addition, messages don't sit in customers' feed next to family and friends as they do when you use the WhatsApp Business API.

See more in our guide: WhatsApp Channels: What is it and how does it work with platforms like charles?

Will WhatsApp take over email?

We believe that email marketing will remain relevant for a long time to come. WhatsApp should be seen as a useful addition to your marketing mix, rather than a replacement.

 

To assist companies in combining email and WhatsApp, we offer CRM/CDP integrations with platforms like Emarsys and Klaviyo. Working together, WhatsApp and CRM platforms can make your cross-channel orchestration stronger.

See charles WhatsApp integrations.
