- Upload lists instantly: Simply export your contact list from Excel or your database into a .csv file and upload it directly, and the system will automatically populate your distribution list in seconds.
- Easily personalize: Avoid the robotic feel of generic spam by using our “mail merge” features to automatically insert specific details, like first names or unique dates, into every bulk SMS text messenger blast.

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.

Yes, bulk SMS sending is legal. However, carriers regulate it, and there are steps you must take to avoid having your messages marked as spam. Personalizing messages is just one way to help you avoid getting blocked by carriers. CompleteSMS can also help you ensure you stay compliant and that your messages reach their intended recipients.
You’re allowed to send bulk SMS in the USA and internationally. If you’re sending messages to recipients based in the United States, you need to comply with 10dlc regulations created by U.S. carriers. CompleteSMS can help you comply with 10dlc.
With CompleteSMS, you can message thousands of people simultaneously, though it’s best to send large lists in smaller batches. Contact us to learn more about the exact number of people you can reach at once.
You can use Gmail to send messages to multiple people simultaneously using distribution lists. You can’t personalize the text with this method, so the message you send will be the same for each recipient unless you send each one individually. To send messages through Gmail, download the CompleteSMS Google Workplace marketplace add-on. The add-on allows you to use your Gmail account to compose and send SMS messages. Any replies you receive will be sent directly to your Gmail inbox.
Yes, our system sends individual messages, they just get sent all at the same time. No one can see who else was in the send, see replies except their own or “reply all”. Group texts are for fantasy football and the church potluck. Bulk texting keeps things professional.
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.
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.
