To reduce your spam score, here are some best practices to follow when creating email content:

1. Avoid using too many exclamation points or all Caps in your subject line, as this can trigger spam filters.

2. Avoid using certain spam trigger words such as "free," "promotional," and "buy now." Instead, try to use more neutral language that is less likely to be flagged as spam.

3. Use a reputable email service provider that has good deliverability rates and spam filtering capabilities.

4. Make sure your email content is relevant and valuable to the recipient. This can help improve engagement rates and reduce the likelihood of your emails being marked as spam.

5. Keep your email list current and up-to-date. Remove any inactive or invalid email addresses to improve your deliverability and engagement rates.

6. Use an opt-in process to build your email list. This ensures that subscribers have given you explicit permission to send them emails, which can reduce the likelihood of your emails being marked as spam. By following these best practices, you can help reduce your spam score and improve the effectiveness of your email marketing campaigns.
