Let's get you Started

Find out how charles can support your business use cases and revenue goals.

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.

 

To get started with charles or ask us about how WhatsApp marketing works, just get in touch.

Can I stay GDPR compliant? 

Companies can use WhatsApp, Facebook and Instagram 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.

What is special about charles AI?

Unlike generic chatbots, our AI is brand-safe. We use a RAG setup (Retrieval-augmented-generation) that searches your knowledge base before generating responses, making the AI faster, more accurate, and less likely to hallucinate information.

What makes charles AI different?

  • Agentic - Built on proven use cases with measurable impact
  • Authentic - Native 1:1 interactions with context from all your customer data
  • Safe - Multiple layers of brand protection including voice and tone controls

The best part? Our AI gets better over time through understanding your customers in detail. The more conversations you have, the more data is gathered to further personalize their interactions.

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.

What about WhatsApp Channels?

WhatsApp Channels is an 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.

Does charles offer Facebook Messenger and Instagram Direct as channels?
Yes, alongside our WhatsApp offering, the charles platform offers Facebook Messenger and Instagram Direct conversational messaging channels. Please reach out to us to learn more.
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 template (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.
