Why Email Deliverability Matters
Poor email deliverability means your important business communications end up in spam folders or get rejected entirely.
The Three Pillars of Deliverability
1. Authentication (SPF, DKIM, DMARC)
SPF Record Example:
v=spf1 include:_spf.skylinesolutions.net ~all
DKIM: Signs your emails cryptographically DMARC: Tells receivers what to do with failed authentication
2. Reputation Management
Your sender reputation is like a credit score:
- Send consistently (not in bursts)
- Keep bounce rates below 2%
- Maintain low spam complaints
- Remove inactive subscribers
3. Content Best Practices
- Avoid spam trigger words
- Balance text and images
- Include unsubscribe link
- Use recognizable sender name
Quick Checklist
- SPF record configured
