SMS 101 Trends & Innovations 5 min read | Amanda Ranville wrote in blog on October 28, 2022

People’s phones are pinging constantly these days. An SMS here. A push notification there. Perhaps an email or a Slack message. It’s a constant barrage of pings, dings and vibrations.

With so many marketing channels to choose from, it can be hard to work out which one’s best when you want to reach your customers on their phones. Here, we put two channels head-to-head to see which one stands out. Enter the ring, SMS vs push notifications.

SMS and push notifications: what’s the difference?

Both SMS and push notifications can appear as clickable ‘messages’ on your customers’ phones. A push notification comes from an app or website – think breaking news or an offer from a retail app. As long as the app is downloaded on a customer’s phone and push notifications are enabled, it can be an easy way to blast out time sensitive alerts. 

SMS, or short messaging service, is a way of sending messages directly to people using their mobile phone number. It’s used for a wide range of business and marketing purposes, such as marketing promotions, appointment reminders, survey and feedback incentives and business alerts, just to name a few. Even better? You can enable two-way conversations with customers via text. 

Before we dive into when you’d want to use SMS vs push notifications, let’s take a look at the key differences between the two.

Here’s why SMS is best for engaging with customers

One less app to download

To send push notifications, you need to build an app. Then, you need your customers to download it and enable notifications. It’s a big ask.

With SMS, all you need is your customer’s phone number and consent to receive messages. They don’t need to download anything or change any settings on their phone.

No WIFI, no worries

For push notifications to work, an internet connection is needed. If your customer isn’t connected to WIFI or the internet, they may miss the notification. 

You don’t need WIFI for SMS. Instead, the message is sent using the customer’s mobile network – which typically has a lot more reach and reliability.

All phones included

Across the globe, more and more people are ditching their smartphones in favour of an old-fashioned ‘brick’, or dumbphone. So much so that global purchases of dumbphones hit 1 billion last year.

Most apps will only work on a smartphone. But all mobile phones can send and receive text messages. By choosing SMS over push notifications, you’re not excluding any customers who choose the ‘brick’.

Vanishing notifications

Ever received a push notification, swiped to open your phone and it’s disappeared? This can be super frustrating. And it could lose valuable sales, especially if a customer can’t find the offer you’ve just promoted. 

SMS messages don’t disappear. They’ll appear as a preview on the home screen, and then customers can easily open their messaging app to find and engage with the full message.

The issue of consent

When a customer downloads an app to their phone, they may unwittingly have notifications set to ‘on’ by default. In fact, Android phones automatically enable them. Yet if you bombard customers with too many messages – or the wrong types of content – then you’ll lose them in a flash. 

With SMS, customers must actively consent to receive messages. This puts them in control, making them less likely to opt out. Of course, you still need to nail the timing and type of content you send via SMS. Always remember to include an opt-out option and be mindful of the fact that you could lose customers if you send the wrong message at the wrong time.

Convinced that SMS is the way to go?

Now you know the pros and cons of push notifications and SMS text messages. Unless you’ve already invested in an app and it’s got great uptake, then SMS is clearly the best way to reach and engage with customers on their phones.
