Why mass texting?


98% of texts are read and 15% of people who read your message take a follow-up action. Texting lets you share information in short concise form that captures attention without taking up valuable time. That’s why even as email engagement rates decline, text messaging metrics are running steady.

Common Questions about Mass Texting

  • How do I get subscribers for mass texting?

    Publish a keyword (eg. JOIN) and have subscribers text it to a 5-digit short code (Text JOIN to 33339) or 10-digit number (Text JOIN to 617 555 0152) to subscribe to your list. You can rent a keyword through a few simple steps.

  • How much does a mass texting tool cost?

    CallHub pricing is pay as you go. You only pay for the texts you sent without any monthly subscriptions. See pricing

  • Is mass texting legal?

    Yes, mass texting is completely legal if the people you text have opted in to receive texts. Unsolicited group texts can incur large fines, so make sure you collect the opt-in beforehand. Unlike mass texting, peer to peer texting lets you text people who have not opted in since each text is manually sent by a person.
