- Create an accurate, professional-looking email
Ensure the message contains legitimate content with no red-flag words
and phrases, as some email filters will automatically flag and disqualify certain words.
- Intersperse text with HTML and consider using alternative (non-HTML) formats
- Study email-filtering policies and guidelines from receiving domains to better understand their content rules and compliance requirements
- Consider using an email filtering service or tool to preview email content on other filters before sending.
