This one's for planning email campaigns, newsletters, and keeping your messages out of spam. It walks you through the difference between conversion-focused EDM and relationship-building newsletters, covers the five main content types (onboarding sequences, campaigns, announcements, feature updates, blog delivery), and gets into the technical stuff like SPF, DKIM, and DMARC setup. The interesting bit is the SEO angle: delivering your articles via email drives non-search traffic that can signal content value to Google. It's comprehensive on deliverability best practices, especially the subdomain isolation approach and Gmail/Yahoo bulk sender requirements. Useful if you're sending more than occasional transactional emails and want a structured approach to content mix and cadence.
