Every Channel

  • Toll-Free Numbers

    Use a 10-digit toll-free number to send and receive messages. Toll-free numbers give the same benefits as dedicated short codes without the short code expense.

    Why Use a Toll-Free Number?
  • Short Codes

    Get a dedicated 5 or 6-digit number that's provisioned for mass text messaging to send your messages through.

    Why Use a Short Code?
  • Landline Texting

    Send and receive text messages through your existing business landline number. This allows you to publish a single familiar number for customers to text and call without having to publish your personal number.

    Why Use Landline Texting?
  • Long Code

    If you would rather get a new one, our API can generate a 10-digit number for you. With this, you can still text for business without using your personal mobile number.

    Why Use a Long Code?
  • MMS

    Send more than just a plain 160-character message. With MMS, you can send pictures and videos as well as 500-character messages for more engaging content.

    Why Use MMS?
  • Omni-Channel

    Using our integrated solution, send messages via text messaging, email, and voice broadcast, so your database is consolidated and your email campaign is perfectly orchestrated with texting.

API Frequently Asked Questions

  • What is Toll-Free API?
    A Toll-Free API is an API that uses a Toll-Free number to send their messages instead of a short code. These are 10-digit numbers that begin with the prefix 800, 888, 877, 866, 855, 844, or 833, and they give you the appearance of a large, nationally known company. Wireless carriers allow these numbers to send text messages for commercial use.

    Toll-Free texting numbers have quickly replaced shared short codes as the best way for businesses to text their customers. It's no surprise why, as Toll-Free texting costs nothing to provision or migrate, and has all the benefits of a dedicated number (including no competition for keywords and streamlined message routing).
  • What are the advantages of a Toll-Free API?
    One of the best things about using a Toll-Free number is that there is very minimal setup time.The process to choose and switch your Toll-Free number should be completed in a matter of minutes. For example, Trumpia's provisioning process is instant and should not require any downtime for your texting campaigns. With a Toll-Free API, you can send SMS text messages and make calls from the same number, so your customers don't have to worry about reaching you via a different number. The same phone number can be used for voice calls, faxes, and texts, which establishes a consistent, familiar channel for communicating.
  • If I don't have a coding team can I still use an API?
    Absolutely. If you don't have a coding team you can either hire Trumpia to build integrations for you, or use our Zapier integrations to recreate many of the same functions.
  • How much does Trumpia's API cost?
    Trumpia's API is highly competitive and our amazing customer support is the cherry on top. Please see our pricing here.
