External communications and customer engagement are a top priority for all successful businesses. However, to really excel in these areas, the same amount of focus should be placed on internal communications. Doing so can boost employee satisfaction and engagement, and bring the workforce together, eliminating silos.

One way to do this is through internal SMS communications - an effective way to deliver critical and time-sensitive information straight into the hands of employees.

Many organizations are beginning to explore the possibilities of using an SMS service provider for employee communication. From internal job postings to important alerts, you can use text messaging for efficient staff communication

Internal texts are a widely underutilized way of communicating with staff members. Let's explore how an organization can use SMS for mass texts.

Why SMS is ideal for internal communications

Internal communications isn’t a strategy that rests purely with HR. In fact, all departments should shoulder the responsibility to ensure cohesive communication between different teams and individual employees.

Some common methods for internal communications include email, newsletters, an intranet or staff presentations. These are all useful in one way or another, but they also have downsides. Emails and newsletters can often go ignored, while an intranet relies on employees logging onto a website to read the necessary information. And presentations need to be organised in advance, rendering them ineffective for urgent announcements.

If you need to deliver an urgent message quickly, SMS is the most effective channel to use. It’s fast, reliable, and most importantly, accessible by just about everyone. In 2014, a study by Gallup reported that texting was the most frequently used communication method for Americans aged under 50.

Nowadays, messaging still remains one of the best channels for converting and retaining customers.

Text messages don’t require internet connectivity to reach their destination. They’re also highly noticeable, usually arriving with a sound or a vibration. And because text messages have to be short (160 characters), they’re also much more memorable than an email or other longer form of communication. SMS is also useful for reaching people off-site who don’t need to work via a computer, for example, a security guard or a utility engineer.

Use cases for internal SMS

When it comes to sending internal text alerts, there is no shortage of potential use cases.

SMS can be used to send out a range of communications from HR, or from one team to another. Here are some use cases and examples:


SMS is perfect for sending out quick reminders about company meetings, conference calls, new business processes, project deadlines or training and certification renewal dates. These can be read quickly by the relevant employees, even when they’re moving around the workplace.


Hi [name]. The quarterly update webinar starts at 10 am prompt. See your email for login details.

Hello [name]. Your Driver CPC training is due for renewal in April. Contact HR for training details.

Shift scheduling and updates

If employees operate via a shift pattern, as they might in a factory, internal SMS can be used to send out notifications of shift schedules. The instantaneous nature of text messages means that changes to shift schedules (e.g. due to staff absences) can be communicated as soon as issues arise.


Overtime opportunity: due to staff absences, we need cover for Friday, 6 am to 2 pm. Contact your line manager if interested.

Hi [name]. Due to a breakdown on the production line, all-night shifts are cancelled for the next week. More info to follow.

Security alerts

Government buildings or businesses that need to protect high-value assets could use internal SMS to inform staff about security breaches, or if there’s a need for the building to be evacuated. 

If you require the immediate attention of employees, the use of internal SMS for internal communication is a game-changer. Depending on the work environment, most employees will have their mobile devices within reach throughout the day.


POSSIBLE BOMB THREAT: suspicious object in main lobby. Investigation in progress. Evacuate via the nearest exit until further notice.

Security alert: Door 351c on level 3 has been breached. Lockdown procedures initiated. Stay at your desk and wait for instructions.

HR updates

Internal SMS can be used to inform staff about new job vacancies, redundancies or changes to working contracts. This is best used as a supplement to more detailed information sent out via email, the intranet or company newsletter.

Employee feedback

Business people having a meeting

Many businesses realise the importance of employee engagement, but not all have a plan to develop the right conditions to make the workplace better. According to the company Gallagher, 60% of North American internal communicators say their organisation has no long-term strategy or vision for employee engagement.

A good starting point is to gather opinions on employee morale and new ways of working, Internal SMS can help you get more survey responses than what you can achieve with an email. Interestingly, three out of five employees ignore emails while at work! 

With SMS, you can easily add a link to an online questionnaire. Be sure to make it mobile friendly so that employees have a smooth experience when completing it.

Emergency alerts

When it comes to a crisis, SMS is the best tool for getting the word out right away. Imagine a scenario where your employees need to work from home - a power outage, a flood, a fire - or an unexpected COVID-19 lockdown. You could quickly send out a text to notify all staff not to travel into work.

Weather warnings are another type of alert that you can send by internal SMS. One example where this might be useful is if you run a vehicle fleet and need to notify drivers about hazardous road conditions. When you use internal SMS to send weather alerts to mobile phones, this form of staff communication helps teams prepare for the day ahead.


URGENT: Problem with water supply at head office. Please work from home - team meeting will be held virtually at 10am as planned.

Severe weather warning: Storm Harlow set to hit southern UK in a few hours. Expect flooding and road closures. Find alternative route.

Getting started with internal SMS

Internal SMS can help you keep employees informed, educated and engaged, and in turn, improve company culture, boost productivity and increase morale. If you are looking for a cost-effective way to streamline staff communication, you should consider text messaging through the use of an internal SMS service.

The first step to getting started is to choose a reputable SMS platform that lets you upload employee phone numbers (or can integrate with your business database). After that, you could set up groups within the platform for different teams. This would enable you to send internal communications to different departments, as well as the entire company or just to specific individuals.
