WhatsApp has an open rate of 98%, compared with 18-25% for email marketing. No other communication channel has those figures in Spain. But it is also the channel where spam and poorly executed automation generate the most backlash. The line between using it well and damaging the brand is very thin.
What can be automated
Transactional messages: order confirmations, appointment reminders, delivery notifications, order status updates. They are useful, expected, and users value them. These do not require specific opt-in if they come from a service the user has contracted.
Communications with pre-approved templates: WhatsApp Business API requires marketing templates to be approved by Meta before they can be sent. This enforces a minimum quality standard and prevents abuse.
Automatic responses to frequent queries: a chatbot that answers standard questions (opening hours, location, availability, returns policy) frees up the human team for complex cases.
Initial lead capture: when a new contact gets in touch, an automated system can collect the basic details before passing the conversation to the sales team. Qualification in five minutes.
What you should not automate
Unsolicited bulk messages: although WhatsApp Business API allows bulk sending to opt-in contacts, the margin is narrow. Messages that look like spam — bulk, generic, out of context — result in user blocks and account restrictions.
Conversations that require empathy: complaints, claims, complex situations. Poorly applied automation here destroys the relationship.
Hard-sell: the channel works better for soft nurturing, valuable content, and useful information. Aggressive sales messages burn through the list quickly.
