Eight guides · one technical book
From the first SMS to Black Friday peak
4notify is not a generic gateway. It is a platform built around specific Greek use cases: SMS to Cosmote / Vodafone GR / Nova numbers via an international gateway, OTP for the four systemic banks, tracking for ACS / ELTA / Speedex, automated Skroutz Verified Customer emails, and practical HDPA compliance from the first opt-in.
Eight guides cover those cases in depth — with legal framework (Law 4624/2019, Law 3471/2006, HDPA decisions), architecture diagrams, code samples, production checklists and FAQ. Each guide is self-contained, but the eight together form a complete technical book.
