Email Marketing Still Has the Best ROI—Here’s How to Use It


Social media algorithms change constantly. Ad costs keep rising. But email? Email consistently delivers the highest ROI of any digital marketing channel—an average of $36 for every $1 spent. Yet most small businesses either don’t use email marketing or use it poorly.
The foundation of email marketing is your list, and quality matters more than size. A list of 500 engaged subscribers who actually want to hear from you is more valuable than 10,000 addresses you bought or scraped.
Build your list by offering something genuinely useful in exchange for an email address: a practical guide, a discount, a free consultation, or exclusive content that your audience actually wants.
The biggest mistake businesses make is only sending promotional emails. Follow the 80/20 rule: 80% of your emails should provide value (tips, insights, useful information) and 20% can be promotional.
For most businesses, a weekly or bi-weekly email is the right cadence. Enough to stay top of mind without overwhelming people’s inboxes.
Your subject line is the gatekeeper. If it doesn’t get opened, nothing else matters. Keep subject lines under 50 characters, make them specific, and avoid anything that sounds like spam. “3 ways to reduce your energy bill this winter” will outperform “Amazing deal inside!!!” every time.
Track your open rates, click rates, and unsubscribe rates. Industry averages vary, but if your open rate is below 20%, your subject lines need work. If your click rate is below 2%, your content or CTAs need attention. Small improvements compound over time.
