The AI answer we saw
For pay-as-you-go flexibility, consider Twilio's WhatsApp API or MessageBird (now Bird), which charge per message or conversation without mandatory monthly platform fees. These are developer-friendly but require more setup effort. If you prefer a managed platform with PAYG-style pricing, AiSensy and 360dialog offer low base fees with usage-based conversation charges aligned to Meta's pricing model. This structure suits businesses with variable messaging volumes or those in early lead generation stages.
