Why Email Marketing Matters in 2026
Email marketing delivers an average return of $36 for every $1 spent — higher than any other marketing channel. For small businesses, email is essential because:
- Direct access: Email reaches customers directly — no algorithm filtering
- Ownership: You own your email list — unlike social media followers
- Cost-effective: Free plans available, paid plans start at $13/month
- Automation: Welcome sequences, drip campaigns, and abandoned cart emails work 24/7
- Personalization: Segment subscribers by behavior, interests, and purchase history
