Emails in Spam at Gmail
If emails sent through Overton.cloud are ending up in Gmail’s spam folder, this guide explains why and what you can do. While Overton.cloud maintains quality controls, Gmail’s filtering depends on domain reputation, email content, and recipient engagement.
Three factors drive Gmail filtering
Gmail weighs domain reputation, email content, and recipient engagement. Improving delivery means addressing all three.
Key Steps to Improve Delivery
1. Verify Configuration
Test your setup using mail-tester.com and aim for a perfect 10/10 score. Proper DKIM and DMARC records are essential.
Authentication first
Gmail strongly favors authenticated mail. Confirm SPF, DKIM and DMARC all pass before troubleshooting anything else—most spam-folder problems trace back to a single failing record.
2. Train Gmail’s Filters
Ask recipients to mark your messages as “Not spam” and to add your address to their contacts before they expect to receive emails from you. This signals to Gmail that your mail is wanted.
3. Monitor Performance
Use Google Postmaster Tools to track your domain reputation, spam rates, and authentication results over time. It’s the most direct window into how Gmail views your domain.
4. Follow Best Practices
Review Google’s official sender guidelines, which emphasize:
- Authentication via SPF and DKIM
- Avoiding sudden increases in sending volume
- Keeping spam complaints below 0.1%
- Maintaining consistent sending patterns
Watch your complaint rate
Keep spam complaints below 0.1%. Crossing that threshold can quickly damage your domain reputation and push your mail to spam.
Additional Recommendations
- Content quality: avoid spam triggers and keep formatting clean.
- List hygiene: remove inactive subscribers.
- Gradual volume building: warm up new domains slowly.
- Engaged recipients: focus on people who actually open and reply.
If issues persist, review your content formatting, check blocklists, or contact Overton.cloud support with specific examples and test results.
