What is Bulk SMS?

Text blasts, also known as bulk SMS messages, are an effective way for businesses to communicate with customers en masse, whether for promotional purposes or to get feedback.

To ensure your business remains compliant with industry-sending guidelines, you need your recipients’ explicit permission to text them, so you can reach potential customers and engage longtime loyalists.

Furthermore, it would be best to inform your subscribers what they are signing up for, how often they will receive messages, and that any applicable message and data charges will be their responsibility.
