Email and SMS Marketing: The $42-Per-$1 Channel Most Small Businesses Are Completely Ignoring
If someone told you there was a marketing channel with an average return of $42 for every $1 spent — and that most of your competitors weren't using it properly — you'd want to know about it.
That channel is email marketing. And the data behind it isn't new. According to the Data & Marketing Association's email ROI research, email has been the highest-ROI digital marketing channel for over a decade — consistently outperforming social media, paid ads, and SEO in direct revenue return per dollar invested.
Yet most small businesses either don't use it at all, or use it so poorly that it might as well not exist.
Why Email and SMS Still Win in 2025
Social media platforms come and go. Algorithms change. Reach drops. Ad costs rise. But your email list is yours. Nobody can take it from you. No algorithm decides whether your message gets delivered.
HubSpot's email marketing benchmarks show that segmented email campaigns — tailored to specific groups based on behavior or interests — generate 760% more revenue than unsegmented broadcast emails. That's not a minor improvement. It's a 7.6× multiplier, and the difference is simply knowing who you're talking to and what they actually need to hear.
SMS goes even further. Open rates for SMS marketing consistently sit above 90%, compared to around 20–25% for email. A well-timed SMS to a warm lead doesn't sit in a folder — it appears on the lock screen of their phone within seconds of being sent.
What Most Small Businesses Are Actually Doing
The most common "email strategy" we see: no email list, or an old list that hasn't been emailed in months. Occasional newsletters sent when someone remembers. No automation. No segmentation. No tracking.
This is the equivalent of having a phone number and never answering it.
What a Real Email and SMS System Looks Like
Welcome Sequence: The moment someone joins your list, they receive a series of automated emails introducing your brand, establishing trust, and moving them toward a purchase. Runs automatically, 24/7, for every new subscriber.
Nurture Sequences: Keep your brand in front of people with valuable content and case studies — so that when they're ready to buy, you're the obvious choice.
Re-engagement Campaigns: Contacts who haven't engaged in 60–90 days receive targeted campaigns to win back their attention.
SMS Campaigns: For time-sensitive offers, appointment reminders, or high-priority announcements, SMS delivers your message directly to the most-viewed screen your customer owns.
Monthly Newsletters: Keep your audience warm, reinforce your expertise, and drive consistent traffic back to your website.
The Revenue You're Leaving on the Table
The brands with the most predictable, sustainable revenue aren't the ones with the most followers. They're the ones with the most engaged lists.
