Email Deliverability: Why Your Emails Aren't Reaching the Inbox
Struggling with low open rates? Learn the technical and strategic best practices to ensure your emails land in the inbox, not the spam folder.
Email remains one of the most effective communication channels for businesses, but only if your messages actually reach the inbox. Poor email deliverability can cost businesses thousands in lost revenue and damaged relationships.
Understanding Email Deliverability
Email deliverability is the ability to deliver emails to subscribers' inboxes. It's influenced by:
The Authentication Trifecta
SPF (Sender Policy Framework)
SPF tells receiving servers which IP addresses are authorized to send email on behalf of your domain. Without SPF, your emails are more likely to be flagged as spam.
DKIM (DomainKeys Identified Mail)
DKIM adds a digital signature to your emails, proving they haven't been tampered with in transit. This builds trust with receiving servers.
DMARC (Domain-based Message Authentication)
DMARC ties SPF and DKIM together and tells receiving servers what to do with emails that fail authentication. It also provides reporting on email authentication results.
Common Deliverability Killers
1. Poor Sender Reputation
Your sender reputation is like a credit score for email. It's affected by:
2. Bad List Practices
3. Content Issues
How to Improve Deliverability

Implement SPF, DKIM, and DMARC properly. This is the foundation of good deliverability.
Step 2: Monitor Your Reputation
Use tools to monitor your sender reputation, check blacklists, and track deliverability metrics.
Step 3: Clean Your Lists
Regularly remove invalid addresses, hard bounces, and long-term inactive subscribers. Use double opt-in for new subscribers.
