Overview
Email marketing is using email to promote products, nurture leads, and build customer relationships. Despite being one of the oldest digital marketing channels (1970s origins), email marketing thrived in the 2010s-2020s with average ROI of $36-42 for every $1 spent — outperforming social media, paid ads, and SEO.
Why Email Works
Owned Audience: Unlike social platforms (algorithm changes kill reach), you own your email list. No one can take it away. Direct Access: Emails land in inboxes. No feed competition, no algorithmic filtering (except spam). Personalization: Segmentation, dynamic content, triggered emails (abandoned cart, welcome series, re-engagement). Measurable: Open rates, click rates, conversion rates, revenue attribution.
Email Marketing Platforms
Mailchimp (2001): Freemium model, SMB-focused, sold for $12B (2021) ConvertKit (2013): Creator-focused (bloggers, podcasters, YouTubers), visual automation Klaviyo (2012): E-commerce powerhouse (Shopify integration), $9.5B IPO (2023) Substack (2017): Newsletter-first, writers own lists, 10% fee Beehiiv (2021): Newsletter growth tools, referral programs, monetization
Email Best Practices (2010s-2020s)
List Building: Lead magnets (ebooks, templates, checklists), pop-ups, gated content Segmentation: Send relevant emails based on behavior, interests, purchase history Automation: Drip campaigns, welcome sequences, abandoned cart recovery Subject Lines: Personalization (Hi [Name]), urgency (24-hour sale), curiosity (You won’t believe…) A/B Testing: Test subject lines, CTAs, send times
Cultural Impact
“The money is in the list” became marketing gospel. Bloggers, influencers, and businesses obsessed over list size. Morning Brew (sold for $75M, 4M+ subscribers) and The Hustle (sold to HubSpot, 1.5M+ subscribers) proved newsletters could be media empires.
The creator economy ran on email: Substack writers ($1M+/year top earners), course creators (Amy Porterfield, Pat Flynn), and coaches built businesses on owned email audiences.
Criticism
Email marketing faced spam backlash (inbox overload), unsubscribe fatigue, and GDPR/privacy regulations (2018). Open rates declined as inboxes became battlegrounds. Some argued email’s effectiveness came from exploiting attention, not providing value.
