Missed Alerts Are Missed Revenue
A forgotten reminder or delayed code can ultimately mean a lost customer.
- Failed Deliveries
Time-sensitive messages like OTPs and delivery updates fail if delayed or unseen by users.

Critical email notifications easily get buried in spam folders and crowded inboxes.
