What is Email Deliverability?
Quick Answer
The percentage of emails that reach the recipient's inbox rather than the spam folder or being bounced.
Email deliverability measures how successfully your emails reach subscribers' inboxes. It depends on sender reputation, authentication (DKIM, DMARC, SPF), content quality, list hygiene, and engagement metrics. A good deliverability rate is above 95%. MisarMail monitors deliverability in real time with automated IP warm-up, bounce handling, and spam trap detection.
