Frequently Asked Questions
What are the different white label options with TextUs?
TextUs offers three white label models depending on how you want to integrate SMS into your product. The full platform option gives your customers a completely branded, standalone messaging experience. The embedded messenger drops an iframe directly into your existing software for contact-record-based conversations. The API option gives your engineering team direct access to carrier operations and deliverability infrastructure without a UI layer.
How does pricing and billing work for white label SMS partners?
Partners pay TextUs a platform retainer for access to the white label infrastructure. From there, you set your own pricing for your customers, collect payment through your existing billing process, and keep the difference. You control the margin entirely.
How does 10DLC registration work? Do I have to manage that?
TextUs manages 10DLC registration on behalf of our white label partners. We’ll walk you through the forms required for the approval process and handle the submission, so you don’t need to navigate carrier requirements of compliance filings on your own.
