How can I prevent my emails from being marked as spam?

If your emails are landing in the spam folder, it is often due to factors related to email content, sender reputation, or list quality. Here are some best practices to improve your email deliverability:

1. Review Your Email Content

Spam filters analyze your email's code and content. Pay attention to the following:

• Avoid Trigger Words: Steer clear of terms commonly associated with spam (e.g., "free," "win," "urgent," "guarantee").
• Use Proper Formatting: Do not overuse capital letters or exclamation marks.
• Balance Image-to-Text Ratio: Ensure your email contains a healthy amount of text. Emails consisting of a single large image are often flagged as spam.
• Check Your Links: Ensure all links are functional, point to trusted domains, and avoid URL shorteners. A clear and working unsubscribe link is mandatory.
• Use Clean Code: Use simple, valid HTML. Complex or broken code can trigger spam filters.

2. Test Before Sending

• Use Testing Tools: Services like Mail-tester.com can analyze your email to highlight potential spam triggers before you send the campaign.
• Send Test Emails: Send your campaign to test accounts at various email providers (like Gmail, Outlook, etc.) to check for deliverability and display issues.

3. Maintain a Clean Recipient List

• Use Opt-In Lists: Only send emails to users who have explicitly subscribed to receive them.
• Clean Your List Regularly: Periodically remove inactive subscribers and any email addresses that result in a hard bounce. This helps maintain a good sender reputation.
