Will WhatsApp cannibalize my other marketing channels?

No. WhatsApp complements your other channels. As we said above, this is about sending the right message to the right person at the right time in the perfect way. With integrations like charles x Emarsys, you can easily do this – improving the customer journey and satisfication while reducing duplication and irritation.  

For example, use WhatsApp for exclusive, pre-sale campaigns and email for the bulk announcement.  
In fact, brands that add WhatsApp to email see a CLV uplift of 25% vs email only.

Can I make a profit in WhatsApp? Isn’t it expensive?

Yes, our customers make a return on campaign spend (ROCS) of around 8-10X on average. The profitability of WhatsApp marketing is unbeatable. This is largely because of the high visibility of WhatsApp notifications and the way it allows businesses to sit right beside people’s friends. Our Emarsys integration helps ensure profitability by allowing you to build targeted audiences for your WhatsApp campaigns using Emarsys' customer data. 

WhatsApp costs more than email initially – because Meta charges €0.07-0.10 per conversation, but the returns and engagement are far higher.
