The Never-Ending Conflict of Email vs. SMS Marketing

sms marketing vs email

A week doesn’t go by when I don’t see an article or blog on why email is still the best digital marketing option. They often espouse the benefits of email while casually dismissing SMS, apps, or other mobile marketing methods without many facts behind them.

It’s understandable. Email has been the mainstay of online marketing for decades, and change is difficult. But it happens, and the “high performing” marketers as Salesforce calls them, know the truth about SMS and email.

Let’s take a look at each of them, and see why the discussion (or articles) should no longer be about one “versus” the other, but about “when” to use each.

SMS Facts

There are also articles that focus only on SMS over other marketing too. Here is a quote from the Huffington Post article as an example,

“Consumers are more willing to engage with businesses through text than through any other medium. According to the Mobile Marketing Association, consumers are five times more likely to respond to a text message than an email. For them, SMS is easy. Responding to a message just takes a few quick taps. Compared with other marketing strategies such as interstitials and pop up advertising, SMS marketing harbours positive feelings with clients instead of frustration”.

And they aren’t wrong, but they are using a broad brush. Many studies show SMS is a good communication method, but it also varies by age. Younger generations prefer SMS, while older generations prefer email. Here are a few other facts about SMS marketing from Salesforce:

  • SMS usage to engage customers grew 111% this year
  • Only 51% of marketers are using SMS
  • Effectiveness of SMS in companies that have integrated mobile into their overall strategy is 73%

That last bullet is very insightful, and leads right to the point I’m trying to make. But first, let’s look at some email statistics.

Email Facts

Experian Marketing Service said the following about email, “Email is undeniably an indispensable asset to marketers and is recognised as the most widely used and valuable touch-point on the customer’s path to purchase”.

Again, they aren’t wrong. But some might see “most widely used and valuable touch-point” and think it’s the only way. Especially if they see statistics like the following:

  • Email is 40 times more likely to acquire new customers than Facebook or Twitter
  • Sixty-one percent of consumers enjoy receiving promotional emails weekly
  • Email is the preferred means of business communications across all age groups

That last bullet directly contradicts the quote about SMS above. In this case, that statistic is from 2015 (MarketingSherpa) and in that short time since it was published, younger age groups have changed their preferences more toward SMS.

Looking at both the email and SMS discussion above, it’s hard not to come to the following conclusion: email and SMS are better together.

Working Together

At the mCommerce Summit earlier this year, the IKEA presenter talked about the future of marketing. He said that consumers want a “unique, relevant, and good customer experience that meets their expectations”. Then he went on to add that the sentiment applies regardless of what device they use.

That concept has become “omnichannel” marketing. It’s not just all channels, but all channels presented in a consistent way to the consumer across all devices. Email and SMS combine to cover most devices they would use. Email is available pretty much everywhere, and SMS is the quickest, most direct way to reach people on a mobile device.

But knowing that doesn’t help you keep them consistent. Fortunately, email and SMS can go together easily with a little planning. For example, you can use them to cross-promote each other. Once someone is on one list, you send them a note about signing up to your other list. After all, if someone opted into your SMS program, then they are interested in what you’re offering. And people realise emails can give you much more information than an SMS. So, they’re likely to want both.

If cross-promotion is the only thing you do to align them, you’re still going to see some great results. Here are a couple of examples:

  • Chuck-e-Cheese, a US-based restaurant and arcade increased email sign ups by 5% using SMS. The customers that signed up via SMS had 10-20% higher email open rates and used mobile coupons 10% more.
  • Walgreens, a US pharmacy and convenience store, found that people who were on multiple lists spent 6 times as much as people who just shopped in their stores.

Of course, there’s more you can do besides cross-promotion. You can send SMS reminders for sales you sent via email. You can send SMS confirmations of sales made from an email promotion. Or send an email with more details about an SMS inquiry.

Hopefully, you can see that the choice between email and SMS is not which one, but when to use each one – and how to use them to complement and supplement each other. When you take the time to present a consistent experience, both you and the consumer benefit.
