Deliverability

refers to the likelihood that a message will successfully reach the intended recipient's inbox, notification tray, or device — rather than being filtered as spam, blocked by a carrier, or rejected by a platform. High deliverability depends on maintaining good sender reputation, following platform-specific compliance requirements, using permission-based contact lists, and carefully managing message frequency and content quality. For WhatsApp in particular, Meta's algorithm evaluates business message quality scores based on user reports and engagement patterns, with low-quality senders facing reduced messaging limits or temporary suspension. ConnectGain provides deliverability monitoring tools, compliance guidance, and sender reputation management features that help businesses maintain high deliverability rates across all messaging channels.
