Who Twilio is best for
Businesses with a developer or an automation tool (such as Zapier, Make or n8n) that want SMS, WhatsApp or voice built into their own CRM and workflows. Choose it over an off-the-shelf texting app when you need custom, automated messaging at scale.
Key features
- Programmable SMS and WhatsApp messaging
- Voice calls and phone numbers
- APIs that plug into CRMs and automations
- Pay-as-you-go pricing
Why it’s worth it
It lets you add SMS touchpoints to your sales and customer journeys, such as meeting reminders or follow-ups, without a separate texting tool. You only pay for what you send.
Things to consider
- It is a developer platform with no ready-made sales interface, so non-technical teams need a developer or an automation tool to use it.
- Costs are usage-based and include number rental and carrier fees, which can add up at high message volumes.
- Sender registration and compliance rules vary by country, and getting them wrong can delay or block messages.
For Australian businesses
Twilio operates an Australian region (AU1) for processing and storing data, although not every product or feature is available outside its US region. It publishes Australia-specific SMS pricing.

FAQ
Twilio: common questions
What is Twilio used for?
Twilio is used to send and receive SMS, WhatsApp messages and phone calls from software, for example appointment reminders, sales follow-ups or verification codes triggered from a CRM.
Do I need a developer to use Twilio?
For most uses, yes, or a no-code automation tool that connects to Twilio. It provides APIs rather than a ready-to-use texting app.
Does Twilio store data in Australia?
Twilio offers an Australian region (AU1), but not all products and features are supported there, so check regional availability for the services you plan to use.
