The likelihood that your messages actually reach recipients' inboxes or chats.
Deliverability is the measure of whether sent messages successfully arrive where the recipient will see them, rather than being filtered, blocked, or marked as spam. It depends on sender reputation, list quality, and recipient engagement.
Poor deliverability silently wastes campaigns: messages that aren't delivered can't convert. Maintaining clean, opted-in lists and sending relevant content protects it.
On chat channels, deliverability ties closely to opt-in compliance and how recipients react to your messages.
If messages don't reach people, nothing else matters; deliverability protects the whole channel's value.
