Operators filter A2P traffic aggressively to protect subscribers. A few practices keep your legitimate messages flowing.
Register your sender ID and content
Registered sender IDs and, where required, pre-approved templates are trusted. Unregistered senders and unexpected content patterns get filtered.
Respect opt-out and consent
Only message people who opted in, and honour STOP requests automatically. High complaint rates get your traffic throttled or blocked.
Use direct routes
Grey routes are cheap but unreliable and often filtered. Direct operator routes deliver better and give you real delivery reports so you can spot problems early.
