Most businesses pick one channel and stick to it. Email or SMS. The ones growing fastest use both and understand when to use each.
Email and SMS aren’t competitors. They’re complements. Each has strengths the other doesn’t. Together, they create a communication system that’s harder to ignore, more responsive to behaviour, and significantly more effective than either channel alone.
What email does well
Email is the workhorse. It handles depth — longer content, multiple links, images, detailed information. It’s where you tell the story, deliver the value, and build the relationship over time.
Email is best for: welcome sequences, nurture campaigns, newsletters, post-sale onboarding, re-engagement campaigns, and anything that benefits from space to explain.
Open rates average 20–25% lower than SMS, but the depth of engagement is higher. A well-written email can do more persuasive work than almost any other channel.
What SMS does well
SMS is the pattern interrupt. It cuts through in a way email can’t – 98% open rate, read within three minutes, impossible to miss. But that power comes with responsibility. Use it too often or for the wrong things, and contacts unsubscribe fast.
SMS is best for: appointment reminders, time-sensitive offers, quote follow-ups, review requests, and moments where immediacy matters more than depth.
The cardinal rule: every SMS should have a clear, single purpose. One message, one action, nothing extra.
How they work together
The most effective sequences use email and SMS in combination, each doing the job it’s best suited for, at the moment it’s most useful.
A practical example for a service business:
- 📧 Day 1 – email: warm welcome, what to expect, link to book a call
- 📲 Day 3 – SMS: “Hi [name], just checking you got our email, happy to answer any questions”
- 📧 Day 5 – email: case study or social proof, soft CTA
- 📲 Day 7 – SMS: “Hi [name], our offer closes Friday, want me to hold a spot?”
- 📧 Day 10 – email: re-engagement or final value email
The email builds the relationship and delivers the value. The SMS creates urgency and cuts through when the email might be missed. Neither is doing the other’s job.
Email tells the story. SMS interrupts the scroll. Together, they’re the combination most businesses never try — and the one that consistently outperforms either channel alone.
The one rule to follow
Don’t use SMS as a cheaper alternative to email. Use it as a different tool entirely. When every message has a clear purpose and SMS is reserved for moments that genuinely need immediacy, it stays effective. When it’s used for everything, it becomes noise and noise gets blocked.
