The Pillars of Deliverability
Landing in the inbox isn't luck; it's about building trust with providers like Google and Outlook. These key factors work together to build your reputation. Click on each pillar to learn why it's crucial for your success.
Domain Configuration
Your email's official passport. DNS, DKIM, and DMARC prove you are who you say you are.
Domain Age & Reputation
Older domains with positive interactions (opens, replies) are seen as more trustworthy.
Mailbox & IP Reputation
You're judged by the company you keep. The health of your provider's server matters.
Blacklists
Public lists of domains and IPs known for spam. Getting listed is a critical issue.
Email Content
Spammy phrases, messy code, and suspicious links can all trigger filters.
Spam Complaints
The most damaging factor. Even a few complaints can tank your reputation.
