Messages sent by scammers often contain harmful links to webpages that have been developed to closely resemble the original. When a potential victim of a phishing attack clicks the link in a text message, they may be redirected to a website containing malicious software. Any information then provided by the user is captured by the fraudsters with the intention of illicit use.

The impostors are often clever and creative in their ways but the senders of business communication are by no means defenseless. You can take a number of essential steps to significantly improve the security of your texting campaigns and include links people will feel safe to click.

Business is built on trust

Since customers across the board, although not being perfectly immune to them, are largely aware of such crooked activities, it’s essential to take steps towards winning their trust in advance by sticking to a number of good practices when launching your SMS campaigns.

In recent years, the number of various phishing attacks has remained consistently high. Therefore, there’s a clear need to counteract the scammers’ operations on the senders’ end.

How to protect your brand and customers from text message phishing?

Now, there are two sides to this phishing coin. One is your business and everything it does to make sure its messaging efforts are secure. The other is the customer, the receiving party, who could perhaps use a little education and reassurance in order to have no doubts about engaging with the texts they receive from you.

Let’s start our discussion of the measures protecting against SMS phishing, SMS spoofing, and spam with this most recent point.

Educate customers about links in text messages

If SMS containing links prompting the customer to take action are a vital part of your business communication operations, consider implementing a concise educational campaign aimed at helping your audience understand what they should pay attention to when interacting with link-containing texts.

💡 This may seem like some extra, unnecessary effort but in fact you’re doing it not only for the people but also in your own business interest. You want as many people as possible to feel comfortable interacting with your messages and clicking the included links. 

That said, the goal here is to make it clear how your organization is going about ensuring messaging safety. Such information can be made a part of your terms and conditions or published in a dedicated section on the company's website. 

Use an authorized sender name in your SMS marketing

Familiarity improves the oh so crucial trust so if you communicate with your customers on the regular, make sure you consistently use the same, authorized sender name for your SMS text messages.

💡 In technical terms, this means confirming your brand name with the SMS platform provider which will then be referred to as your SenderID. It will preface all your outgoing texts, sitting atop of the content. 

This way you create a situation where you’ve been officially confirmed by an authoritative third party and are always displaying your brand name to customers, which they are accustomed to. Any deviation from it should instantly raise their suspicion and prevent them from engaging with any potentially malicious links included within, mitigating the risks.

Avoid public URL shorteners for SMS links

You may be tempted to go the easy route and get or another URL shortener to clip your clickable link so that it fits into an SMS along with the rest of your message. This, however, may come back to bite you.

💡 Phishing cybercriminals are well aware of publicly available link shorteners and often exploit them to disguise their malicious URLs.

With no identifiable branding to them, these links can serve as wide open gateways to whatever scheme is waiting on the other end. Upon seeing such a random link, customers may be hesitant to click it and rightfully so. The significant popularity of these services does in no way translate to increased security. Follow the link for more detailed discussion on short links in SMS.

Use trusted SMS software providers

Expert business messaging software providers will offer you the option to both set a custom, trusted sender name and shorten links securely.  

💡 To improve the efficiency of your communication even further, you may want to use branded links in your SMS messages. 

If you decide to go for it, you can securely shorten any link to just 17 characters to look something like this:
