Hey Indie Hackers! We just launched SendAPI, a unified messaging API that lets you send WhatsApp, SMS and Email from one API key. No separate accounts, no complicated billing. Plans start from $9.99/month with a 3-day free trial. Would love your feedback! sendapi.co
Managing multiple messaging providers usually turns into a billing nightmare because each channel has its own hidden costs and API quirks. Consolidating everything into a single key is a massive relief for developers who just want to ship notifications without spending a week on integration. Since you're offering a flat pricing model for all three channels, are you focusing the early features on transactional reliability or are you planning to add marketing broadcast capabilities for those handling larger volumes?
