What You'll Learn
5-Step Email Deliverability Checklist
Step 1: Set up SPF, DKIM, and DMARC records
Add SPF record to authorize sending servers, configure DKIM for email signing, and set DMARC policy to prevent spoofing. Use DNS checker tools to verify all records are published correctly.
Step 2: Warm up your email domain gradually
Start with 10-20 emails per day and increase by 10-20% daily over 2-4 weeks. Use automated warmup tools like Warmy or SmartLead to simulate natural email activity with opens, replies, and forwards.
Step 3: Monitor sender reputation with Google Postmaster
Add your domain to Google Postmaster Tools to track IP reputation, spam rate, and domain reputation. Maintain spam rate below 0.3% and monitor for sudden drops in reputation score.
Step 4: Clean your email list regularly
Remove bounced emails within 24 hours, validate email addresses before sending, and segment inactive subscribers. Use email validation APIs to check deliverability before adding contacts to your list.
Step 5: Avoid spam trigger words and test content
Run emails through spam checkers before sending, avoid excessive capitalization and exclamation marks, and maintain a healthy text-to-image ratio (70:30). Test emails with Mail-Tester.com to catch issues.
