Question 1

What is the best alternative to Twilio?

The strongest Twilio alternatives depend on what you need. Telnyx rates highest among the options here; the comparison table covers price, free tier, and rating, and the "what each alternative is best for" section matches each option to a use case.

Question 2

What is Twilio and what is it used for?

Accepted Answer

Twilio is a cloud communications platform that provides APIs for sending SMS, voice calls, WhatsApp messages, email, and user verification. It is aimed primarily at developers who want to add messaging and communication features to their own applications. Founded in 2008 and headquartered in San Francisco, it is a publicly traded company on the NYSE under the ticker TWLO.

Question 3

Is Twilio HIPAA compliant and does it sign a BAA?

Accepted Answer

Twilio supports HIPAA eligible workflows and will sign a Business Associate Addendum (BAA) for customers who handle protected health information, but only for a defined set of eligible products: SMS, Voice, Video, Conversations, SendGrid, and select Flex configurations. Twilio treats HIPAA compliance as a shared responsibility, so the customer must configure and use the eligible products correctly. You must execute the BAA before sending any PHI through the platform.

Question 4

How much does Twilio charge per SMS in the US?

Accepted Answer

Twilio's US SMS pricing is usage-based, with a base rate of $0.0083 per message segment to send or receive on A2P 10DLC. On top of that, US carriers add surcharges of roughly $0.003 to $0.005 per segment depending on the carrier, so the typical all-in cost is about $0.011 to $0.013 per segment. Long messages are split into multiple segments, each billed separately.

Question 5

Can Twilio keep my data in the EU?

Accepted Answer

Yes, Twilio offers EU data residency in its Ireland (IE1) region for Voice, SendGrid Email, Chat, Segment, and SMS, so that certain customer data can be stored and processed in the EU rather than the United States. Coverage has gaps: MMS, WhatsApp, RCS, Verify, Studio, Flex, Conversations, and Functions are not supported in IE1. Twilio also states GDPR compliance and provides a Data Protection Addendum, but you should confirm data residency coverage for the specific products you plan to use.

Question 6

Can I switch from Twilio without rewriting my code?

Accepted Answer

Often, yes. Courier sits in front of these providers behind one API, so you can route through Twilio or an alternative, or fail over between them, without rewriting your integration each time.
