What Is Bulk SMS?
Bulk SMS is a service that lets your company send texts to multiple individuals simultaneously.
Using a bulk SMS service streamlines your messaging, saving you time, money and effort.
Is Bulk SMS the Same as Group Texting?
No, Bulk SMS, or mass texting allows you to reach more than one person at the same time, each receiving their own message. The recipients don’t know who else received messages. And if someone were to reply to their message, the reply is only sent to the original sender. It’s essentially a time-saving one-to-one message sending option.
Group texting sends the exact same message to multiple people at one time, but all recipients can see the other recipients and any replies sent go to everyone on the original message. Like when Aunt Sally says she’s bringing three-bean casserole and Judy’s bringing Jell-o.
When to Use Mass Texting
Companies across industries can take advantage of bulk SMS, as there are multiple use cases for it, including:
- Sending appointment reminders: You can use bulk SMS to send appointment reminders to clients who have services booked in a week, two days or the next day.
- Sending updates: Bulk SMS is an efficient way to keep customers, members or students in the loop. For example, if your school needs to close because of bad weather, you can send a bulk text to all the students or parents. If your gym is changing its operating hours, you can communicate the change to members through a text.
- Sending emergency or critical alerts: Government agencies and utility companies can use bulk SMS to reach residents and alert them to emergencies or other critical problems, such as power outages or water main breaks.
- Sending staffing updates: Bulk SMS lets companies keep their employees updated on policy changes or upcoming meetings. You can use mass texting to send employees their weekly schedules or find a fill-in when someone calls out sick.
- Sending payment reminders: Use bulk SMS to send customers payment reminders a week or day before their bills are due.
Bulk SMS Best Practices
Spam is prevalent in the world of text messaging, so it’s important to do what you can to avoid being marked as spam by your customers or their phone carriers. Following mass texting best practices will help ensure your messages reach their recipients:
- Get consent: Your customers should opt into or agree to receiving texts before you send them messages.
- Identify yourself: Always make it known who the message is coming from, even if you’ve sent messages to a customer in the past.
- Send texts from a dedicated number: Using a dedicated number means your messages will always come from the same phone number. People can save the number as a contact and can easily see who the message comes from when they look at their notifications.
- Offer an out: Include an unsubscribe option with each message, such as “Text STOP to unsubscribe.”
- KISS: Keep your messages simple, short and sweet. Your customers should see what you’re offering or suggesting with a quick glance.
- Send messages during the day: Timing matters. Send your messages when people are most likely to be looking at their phones.
- Don’t over-text: You can have too much of a good thing. Be cautious about sending people too many texts.
- Know the rules: Be familiar with regulations in the country where you’re texting. Some countries require senders to register message templates before sending.

The Benefits of Mass Texting
If you follow the rules and best practices, bulk SMS has multiple benefits, including:
- High open rates: People are more likely to open and read a text than an email message. You can feel confident that a recipient actually saw your message rather than it going to a spam folder.
- Personalization: You can personalize your bulk messages to include your custom sender ID, the recipient’s name or other details specific to the recipient. Doing so increases response and makes it less likely that your message will be marked as spam.
- Easier communication: With our 2-way texting feature, communication can be a two-way street even when texting in bulk. Customers can reply to your messages and you’ll be the only one to receive them.
