Deliverability
Deliverability is the rate at which your emails or texts actually reach the recipient's inbox rather than being blocked or filtered as spam. Good deliverability depends on consent, sender reputation, and proper setup, and it directly affects how many people ever see your messages.
Deliverability determines whether your messages arrive or vanish into spam folders and carrier filters. You can write a perfect email or text, but if it never reaches the inbox, it does no good. Deliverability is about earning the trust of email providers and phone carriers.
Strong deliverability comes from doing things right: getting consent, honoring opt-outs, keeping a clean list, and following technical setup like domain authentication and 10DLC registration. Protecting your sender reputation keeps your messages landing where customers will see them.
