Why is WhatsApp the best channel for customer retention?

WhatsApp has very high open rates (around 90%). In addition, it allows for highly personalized communication and rich interactivity. All this improves engagement and conversion and makes it a powerful tool for retaining customers and fostering long-term relationships.

Can WhatsApp Business communications be personalized for each customer?

Yes. WhatsApp enables personalized messaging at scale. Its interactive features collect rich customer data to help brands create highly relevant campaigns. Plus, integrations with CRM tools like Klaviyo and shop systems like Shopify enable brands to use data from previous interactions and behavior, enhancing engagement and relevance.

How do I use WhatsApp most efficiently and keep customers' interest without being intrusive?

Our most successful customers use WhatsApp not just for marketing campaigns. They send useful notifications like delivery updates, product tips, special offers and QR-code tickets and vouchers. A rule of thumb is that you solve a pain point of your customer or at least share useful information or deals.

To keep it efficient, set up automated campaigns and flows that run in the background earning you revenue. See more cost-saving tips in WhatsApp.  

Can WhatsApp messages really drive revenue?

Absolutely. The average return on campaign spend (ROCS) for our customers is of 8-10X – far higher than ads and other channels like email. Personalized and timely messages, in an app consumers already love, significantly increase engagement and conversion rates. WhatsApp is increasingly a key tool for retaining happy and loyal customers.
