Set up service SMS messaging in the conversations inbox and help desk

Last updated: November 2, 2026

Available with any of the following subscriptions, except where noted:

Connect an service SMS channel to help desk or the conversations inbox to receive and respond to customer inquiries via text message. For example, you can include your SMS number on your website or in onboarding materials so customers can text your team with questions. Reps can then reply directly to provide quick updates on high-priority tickets or confirm service appointments.

Please note: if you're a Super Admin, you can opt your account into the Service SMS beta.

Please note: HubSpot works with a third-party SMS service provider, Twilio, to provide SMS messaging services to customers who purchase either of the SMS add-ons. Please review the information listed below carefully:

  • You must comply with applicable laws, regulations, Twilio's policies, including, but not limited, to the Twilio Acceptable Use Policy and the Twilio Messaging Policy, Twilio's Forbidden Message Categories for US and Canada, and industry standards, including, but not limited to, telecommunications providers’ policies and US carrier requirements. Please carefully review Twilio's Forbidden Message Categories for US and Canada to make sure you can use HubSpot's SMS tool. Please review US carrier penalties for non-compliant messaging here. To date, T-Mobile is the first U.S. telecommunications provider to announce non-compliance fees for violations of T-Mobile’s Code of Conduct. Twilio will update these guidelines accordingly if/when additional U.S. telecommunications providers announce non-compliance fees.
  • Twilio uses A2P, a system that allows authorized businesses to send Application-to-Person (A2P) type messaging via standard 10-digit long code (10DLC) phone numbers, as well as via short code numbers for high volume senders. Carriers in the US consider all Twilio traffic to be A2P. Learn more about A2P and the required information for registration in Twilio's documentation.
  • A Twilio account is not required to use SMS messaging in HubSpot.

 

Permissions required Super Admin or SMS setup permissions are required to set up SMS messaging in your HubSpot account.

Understand SMS consent and response windows

  • Subject to applicable law, carrier requirements, and Twilio’s policies, when a customer texts your registered SMS number first, that may be treated as implied consent for you to respond as part of the same service conversation. The customer does not need to provide explicit consent, such as texting START for that response. This only applies to Service SMS use cases and does not apply to marketing or promotional messages.
  • Customers can opt out at any time by texting STOP or another supported keyword. After a customer opts out, you can’t send further messages unless they send a new message, which re-establishes consent.
  • The following response windows apply:
    • A support rep must respond within 48 hours of the customer’s first message. After this window, you can no longer respond.
    • After the initial reply, you can continue responding as long as you reply within 30 days of the customer’s latest message and the related ticket remains open.
    • The time remaining to reply is shown in the conversation.
