How to Fix Emails Going to Spam

Stop your emails from going to spam with these proven fixes. Configure authentication, improve content, and monitor deliverability for better inbox placement.

1. Set up SPF, DKIM, and DMARC authentication. Access your domain's DNS settings through your registrar or hosting provider. Add an SPF record specifying authorized sending servers, configure DKIM signing through your email service, and create a DMARC policy to prevent spoofing. These records verify you own the domain and authorize specific servers to send on your behalf.
2. Clean your email list and remove inactive subscribers. Remove email addresses that consistently bounce, haven't engaged in 6+ months, or were added without permission. Send a re-engagement campaign to inactive subscribers before removing them. High bounce rates and low engagement signal poor list quality to spam filters.
3. Avoid spam trigger words and optimize content. Replace promotional language like 'FREE', 'URGENT', 'ACT NOW' with natural alternatives. Maintain a text-to-image ratio of at least 60:40, avoid excessive capitalization, and limit exclamation marks. Write conversational subject lines under 50 characters that accurately describe your content.
4. Configure proper sending reputation. Send emails from a consistent domain and IP address to build reputation over time. Start with small send volumes to new domains and gradually increase as engagement improves. Monitor your sender reputation through tools like Sender Score and Google Postmaster Tools.
5. Include clear unsubscribe options and sender identification. Place an obvious unsubscribe link in every email footer and process requests immediately. Include your physical business address and clear sender identification. These elements are required by law and help establish legitimacy with spam filters.
6. Monitor deliverability metrics and blacklist status. Track delivery rates, open rates, and spam complaint rates through your email service analytics. Check your domain and IP against blacklists using tools like MXToolbox. Address any blacklist entries immediately by contacting the listing organization and fixing underlying issues.
7. Warm up new sending domains and IPs gradually. Start with 50-100 emails per day from new domains or IP addresses, increasing volume by 25-50% weekly based on engagement metrics. Send to your most engaged subscribers first to establish positive sending patterns. Avoid sudden volume spikes that trigger spam filters.
