Bulk SMS
With bulk SMS, you can send one message to thousands of recipients at the same time. It is an efficient way to reach customers, users or employees in seconds — straight to their mobile phones.
What is bulk SMS?
Bulk SMS means sending the same SMS message to many recipients at once. Instead of writing to each person individually, you can create your campaign in inMobile and send your message to entire recipient lists in seconds — or send bulk SMS from your own system via inMobile's SMS API.
Bulk SMS is often used for marketing campaigns, service messages, notifications or internal communication, where many people need to receive the same information at the same time. With a bulk SMS solution, you can manage your campaigns and make sure they are sent at the right time to the right recipients.

Why use bulk SMS?
When you need to communicate with many recipients at the same time, you typically do so through a professional SMS gateway. Speed and delivery reliability are crucial. With bulk SMS — or group SMS — you can reach your entire audience in seconds and make sure important information gets delivered.
An SMS lands directly on your recipient's phone, where 95% of all messages are opened within a few minutes. That means you can be confident your message will be seen quickly.
Bulk SMS is therefore an effective channel when many people need to receive the same message at the same time. This could include marketing campaigns, service messages, operational updates or internal communications.

How to send bulk SMS
#1 Create or import recipients
Before you can send bulk SMS, you need to create a recipient list. You can do this by adding contacts manually or by importing a list of mobile numbers from, for example, a spreadsheet or a CRM integration.
Once your recipients are created, you can organize them into different lists and segments. That way, you can easily choose exactly which people should receive your message.
#2 Write your SMS message
Once your recipients are selected, it's time to write your SMS. A good SMS is short, clear and has one clear message — for example, an offer, a reminder, or an important update.
You can also personalise the message with the recipient's name or add a link to a campaign, booking page or landing page using the link tracking feature. This makes the message feel more personal and increases the likelihood of a response.
#3 Send now or schedule your messages
Once your message is ready, you can send it immediately or schedule the campaign for a specific time that suits you.
Scheduling makes it easy to time your SMS messages so they are sent exactly when it makes the most sense — for example before an event, at the start of a campaign, or as a reminder to your recipients.

What can you use bulk SMS for?
SMS marketing
Bulk SMS is an effective channel for marketing campaigns when you want to reach many customers quickly. This could be for sales, product launches, events, or sharing a discount code with your customer club.
With bulk SMS, you can send campaigns to entire customer lists or selected segments based on, for example, purchase history, interests or behaviour. This makes your messages more relevant to the recipient.
Many companies use SMS as a supplement to other marketing channels, where a short, direct message can create extra attention and drive traffic to your webshop, booking page or landing page.
Service messages
Bulk SMS works well for service messages when many recipients need to be informed at the same time. This could include changes to opening hours, operational updates, system updates, or other important information for customers and users.
With bulk SMS, you can quickly send the same message to all relevant recipients and make sure the information reaches them in time. This makes SMS especially useful for messages where timing and clarity matter.
Many companies therefore use SMS to keep customers and users up to date with important information — without having to contact each recipient individually.
Internal communication
Bulk SMS is also useful for internal communication in companies where employees need to receive the same message quickly. This could include changes to shift schedules, operational updates, or short updates for specific teams or departments.
Bulk SMS lets you reach employees directly on their mobile — even when they're not sitting at a computer or don't have access to internal systems. This makes SMS an effective channel in organizations with employees on the go.
Many companies in sectors such as retail, logistics, manufacturing and services use SMS to make sure important internal information is seen quickly by the right employees.
Notifications
Many companies use bulk SMS for notifications and automatic messages. For example, these can be appointment reminders, status updates, or notifications about changes to an order or booking.
When a notification is sent as SMS, the message is delivered directly to the recipient's mobile, where it is typically opened within a few minutes. This makes the channel suitable for messages that need to be delivered quickly and are easy to read immediately.
Bulk SMS can also be integrated with the company's existing systems via inMobile's SMS API, so notifications are sent automatically when specific events occur. This also makes bulk SMS an effective solution for automated communication.
