This helps businesses keep customers informed at the right moment and avoid confusion or delays.<\/p>\n\n\n\n<p>WhatsApp also offers end-to-end encryption, so messages stay private and secure. This makes it a trusted channel for sending sensitive information like verification codes and account alerts.<\/p>\n\n\n\n<p>Compared to SMS and email, WhatsApp creates better engagement.
