An icon of a plus symbolAn icon of a minus symbol Businesses can use mass texting for use cases like: sending security notifications, emergency alerts, reminders, feedback requests, or special marketing offers to a large audience at once.

An icon of a plus symbolAn icon of a minus symbol Group texting refers to an individual sending a message to a group of selected recipients. Some smartphone models now allow users to send a single message to up to 30 recipients, while others max out at 10. Mass texting, on the other hand, refers to messages sent with a text messaging API or SMS service that delivers texts to a list of recipients. The list can include as many people as a group message or up to millions of recipients. ### Can I send mass text messages to existing customers? An icon of a plus symbolAn icon of a minus symbol You can send mass text messages to existing customers if they have opted in to receive those specific kinds of text messages from you. If you do not have explicit consent from existing customers, you’ll need to get it before you can send them any text messages. You can ask for their permission through an email, over the phone, or at a point of sale with options for the types of messages they can choose to receive from you. Once you have a customer’s opt-in, you can add them to your mass texting list and start communicating with them via text. ### Is mass texting legal? An icon of a plus symbolAn icon of a minus symbol In general, mass texting is legal when you have explicit opt-in consent from recipients, you send messages from a verified number, you respect opt-out requests and you adhere to legal and regulatory requirements. Due to the rise in spam messages and smishing scams in the past decade, there is additional scrutiny for mass texting and you need to take extra care to stay in compliance.
