What is email deliverability?

Email deliverability is the ability of your message to reach the inbox, not just the server. Many senders confuse inboxing with sending, but deliverability is about placement, not transport. A classic way to explain it is that deliverability is the art of avoiding the spam folder while delivery is the science of avoiding the bounce.

When you send an email from [email protected], the message must sail past authentication checks, filtering rules, reputation scoring, and engagement tests before the mailbox provider decides where it should land.

It is the art and science of convincing Gmail.com, Outlook.com, Yahoo.com, iCloud.com, and every other provider that your message deserves the clean well lit dock rather than the junk lagoon.
