A DIY stack uses Twilio for voice and SMS, an email vendor for email, and your own integration code. Your team maintains that code.
Choose the DIY stack if you want to select each vendor and have a team to maintain the integration. Choose Hail if you want voice, SMS, and email behind one MCP endpoint.
You select the vendor for each channel and keep full control of routing and data. You do not depend on one provider for all channels. This is a valid choice for teams that want to operate their own communications system.
You do the integration work. You write webhook normalization and a unified event store. You also do the A2P 10DLC paperwork: brand registration and campaign vetting. The carrier review takes 10 to 15 days before your first text.
You handle TCPA consent, SPF, and DKIM, and you reconcile several accounts and invoices. Each channel that you add needs more integration code.
With a DIY stack, your team builds and maintains the integration code.
Hail handles carrier registration, the phone number, and the email domain. You use one API key and one balance. Every operation is available through a documented REST API, a CLI, and an MCP server.
Hail is open source. You can self-host it.
