Frequently asked questions
Sent is a single messaging platform for SMS, WhatsApp, and RCS. Your product makes one request, and Sent handles routing, delivery, fallback, and compliance across every channel and every country you operate in. You stay in control of what gets sent and to whom; Sent takes care of how and where it is delivered.
Sent is built for businesses where messaging is core to the product, spans more than one channel, or runs at scale. That includes B2C SaaS apps, banks and payment platforms, e-commerce stores and marketplaces, and platforms that embed messaging into their own products. It also suits logistics, IoT, and AI-driven systems that send large volumes of time-sensitive messages.
It removes four problems that grow with every customer you add:
- Provider sprawl. Instead of separate contracts, integrations, and dashboards for each channel and country, you have one API, one set of credentials, and one place to see every message.
- Messages that must arrive. Login codes, payment confirmations, and security alerts fall back automatically to another channel or provider when one fails, so a single outage doesn't lock customers out.
- Compliance. US 10DLC registration, WhatsApp Business account approvals, sender ID rules, opt-outs, and quiet hours are handled at the platform level.
- Cost at scale. Each message is routed through the cheapest route that can deliver it, instead of one fixed rate.
The result is that your team spends its time on your product rather than on messaging infrastructure.
In minutes. Verify an email address and phone number, with no credit card, and you can send real messages using six pre-built verification templates, through the API or the no-code dashboard Playground. A full production setup with your own templates and sender usually takes 1 to 2 days.
You pay a monthly platform fee for each contact you actually message, plus carrier fees passed through at cost. There's no minimum commitment to start.
For high volumes, around 1 million or more messages a month, custom enterprise pricing is available through sales.
Sent is SOC 2 Type II certified, and data is stored in AWS regions in the US and EU. Compliance controls run on every message: sends to opted-out contacts are blocked, STOP replies are honoured on every channel, and messages that would arrive during a country's quiet hours are held until the window opens.
One API. Every channel.
