1. Authenticate Your Emails Implementing email authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) can help prevent your emails from being marked as spam. These protocols verify that your emails are coming from a legitimate source.
2. Monitor Your Sender Reputation Regularly monitor your sender reputation using tools like Sender Score. A poor sender reputation can lead to your emails being filtered into spam folders. Take corrective actions if you notice a decline in your sender score.
3. Avoid Spam Trigger Words Be cautious with the language you use in your emails. Avoid using words and phrases that are commonly associated with spam. These can trigger spam filters and reduce the deliverability of your emails.
4. Test Your Emails Before sending out your email campaigns, use email testing tools to check how your emails score against spam filters. This can help you identify and rectify any issues that might cause your emails to be marked as spam.
