# What is bulk messaging?

> Bulk messaging is sending a large volume of messages — SMS or another channel — to many recipients at once, for alerts, notifications, or marketing campaigns. It depends on a consented list, a registered sender ID, correct encoding to control cost, adequate throughput, and delivery-receipt monitoring. The scale is what makes list quality and route quality matter: small per-message problems multiply across a large send.

## The essentials

A clean, consented recipient list; a registered sender ID; messages kept to one segment where possible; enough throughput for the volume; and DLR monitoring to catch failures. See /answers/how-to-send-bulk-sms.

## Why quality scales

At bulk volume, a stray Unicode character doubles cost across every message, invalid numbers waste a slice of the whole send, and a grey route fails at scale. Validate numbers and fix encoding before you press send. See /answers/sms-character-limit-explained and /products/hlr-lookup.

## Beyond SMS

Bulk messaging also runs on WhatsApp and RCS for richer, opted-in campaigns, with SMS as the universal reach layer. Orchestrate the channels rather than blasting one. See /products/omnichannel and /answers/sms-marketing-best-practices.
