Deliverability

Also known as: Email Deliverability, Inbox Placement

Deliverability is how often your emails land in the inbox instead of spam or getting blocked. Strong deliverability means people actually see what you send and can act on it.

Deliverability is the chance your email has to land in the inbox instead of spam or getting blocked. It depends on your sending history, how clean your list is, and how people react to what you send. If people open, click, and do not complain, inbox providers build trust in you. If they ignore or mark messages as spam, that trust drops.

Good deliverability means more people see your campaigns, automations, and transactional emails. That helps revenue, onboarding, and support without sending more volume. Poor deliverability wastes money because you pay to send emails that never get read. Most teams track it by watching inbox placement, complaint rate, bounce rate, and engagement.

To protect deliverability, send only to people who gave clear permission and still engage. Use proper authentication like SPF, DKIM, and DMARC and keep your sending domain consistent. Remove dead addresses and frequent non openers on a regular schedule. Start new sending setups slowly so inbox providers can learn to trust you.
