Whether SMS marketing is more effective than email marketing depends on several factors, including the goals of the campaign, the target audience, and the industry.
SMS marketing has some advantages over email marketing, including:
High open rates: SMS messages have a higher open rate than emails, which can help ensure that your message is seen by your audience.
Direct communication:SMS messages are delivered directly to a recipient’s mobile device, which can help ensure that your message is received and read.
Timeliness: SMS messages can be sent and received in real-time, which can be useful for time-sensitive offers and promotions.
However, SMS marketing also has some limitations, including:
Limited character count: SMS messages have a limited character count, which can make it challenging to convey complex messages.
Permission-based: Like email marketing, SMS marketing is permission-based, which means that you must have a recipient’s consent to send them messages.
Higher cost: SMS marketing can be more expensive than email marketing, particularly for larger campaigns.
Overall, whether SMS marketing is more effective than email marketing depends on your specific goals, target audience, and industry. In some cases, SMS marketing may be more effective, while in other cases, email marketing may be a better choice.

It can be more effective in some areas, yes. It all depends on the preferences of your target audience, as well as on how your approach to both SMS marketing and email marketing.
SMS marketing — and marketing through text messages in general — has one big advantage over email: its open rate. Typically, when a business sends out an email, somewhere between 10 and 25% of recipients will open it, and only about 5% of that total number will engage with the email. Which usually means they’ll click on a link sent by the brand.

The open rate is low because a lot of people don’t check their inbox every day, and because marketing emails often end up in spam folders. Those two factors are not a problem in SMS messages, which is why they have an open rate that can be as high as 90%. That in theory should mean your sales pitch will reach a lot more people if sent through SMS, which is a key reason why so many businesses choose SMS over email.

Of course, there is no reason to choose one over the other, and there are plenty of platforms that make it easier for businesses to manage both types of marketing. Some services even allow businesses to send SMS from landline, eliminating the need to get a business cell phone.
