Mobile Marketing: Three Channels That Actually Work (and One That Doesn't)

Someone sold me on the idea that a mobile marketing campaign had to incorporate every available channel at once — text, email, app, QR codes, social. That advice cost me about three months of fragmented effort before I simplified and started seeing actual results.

Text Messages: Fast, Personal, Easily Abused

SMS is the most direct channel in the mobile toolkit. Open rates are genuinely higher than email — most texts get read within minutes. The problem is that this directness cuts both ways. If you send a promotional text at 6 AM or twice in one week for no good reason, you'll see unsubscribes that you simply won't recover. The channel only works if you treat each message as something your subscriber is glad received.

Practically, this means limiting yourself to one or two messages per week maximum, and making sure every message contains something concrete: a specific discount code, an event reminder, a product that just arrived. A good SMS marketing tool gives you scheduling controls and delivery analytics so you can see what time of day your specific audience actually engages. The default advice is late afternoon on weekdays — but your audience may be different.

Email on Mobile: Still Underused

A lot of people treat mobile email as a separate initiative, but most email is already opened on phones. The real question is whether your emails are designed for that context. A three-column newsletter with tiny font and unresized images is a disaster on a phone screen. A single-column layout with a large call-to-action button is not fancy, but it converts.

The upside of email over text is length. You can actually explain something, include a product image, and give context that would feel invasive in a text. A solid email marketing platform with mobile preview and A/B testing is worth paying for. The combination of well-timed texts for urgency and properly formatted emails for depth is more effective than either channel alone.

Mobile-Optimized Sites: Table Stakes Now

A few years ago, having a mobile-friendly site was a differentiator. Now it's just the baseline expectation. What still differentiates is page speed — specifically, how fast your site loads on a cellular connection. A website speed testing tool will tell you exactly where you're losing visitors. Images are usually the culprit. Compressing images and deferring anything non-essential to load after the main content makes a measurable difference in both user experience and conversion.

Keep the mobile site structurally simple. Navigation that requires small-target taps, horizontal scrolling, or popups that can't easily be dismissed will drive users away faster than any competitor's pricing advantage.

What I'd Skip

QR codes are genuinely useful in physical contexts — on packaging, in a storefront window, in a printed flyer. But I've seen business owners spend real energy generating QR codes for things that are already directly clickable on a screen. That's busy-work. If your customer is already on their phone reading your email or looking at your social post, a direct link is always better than a code they have to scan with the same device they're holding.

I'd also push back on the pressure to build a dedicated mobile app builder product early. The maintenance cost, the update cycle, and the barrier to download mean that most small businesses are better served by a fast mobile site than a native app with 200 downloads that never gets updated. Build the app when you have a specific function that genuinely requires it — not because it sounds impressive.
