Plain
Plain built an autonomous support agent, and has now built the controls to trust it.
A side-by-side editorial comparison of Infobip and Twilio — release velocity, themes, recent moves, and the top alternatives to consider.
A CPaaS rebuilding around AI agents that act, not just channels that deliver
Infobip publishes quarterly roll-ups, and the feed stores each quarter twice — once as a bare label, once as the summary paragraph. Across Q3 2025 to Q1 2026 the through-line is consistent: AgentOS unifying the communication stack, AI agents that take action rather than reply, MCP servers connecting models to real channels, and AI voice work under Vocalize, against continued WhatsApp, RCS and CDP investment.
Twilio is retiring its old serverless runtime while pushing consent and deliverability control into APIs.
The changelog reads as a platform in consolidation. Functions Classic is being retired with an automatic migration, the REST API certificate chain is being rotated, and older SendGrid behaviours are being trimmed. Alongside that, the messaging and email surfaces keep gaining programmatic control that used to be manual or impossible: bulk WhatsApp templating with cross-channel fallback, dedicated IPs with managed warm-up for Twilio Email, and a Consent Management API that can now clear network-level toll-free opt-outs.

The company is repositioning from delivering messages to running autonomous customer interactions on top of them. Channels are becoming the substrate; the product being sold is the agent layer above. MCP servers matter most here — they make Infobip's channel reach callable by models a customer already runs, rather than requiring Infobip's own agent builder.
Expect the next quarterly to lead with AgentOS depth — orchestration, handoff and measurement across agents — since the channel and MCP groundwork it needs has now shipped over three consecutive quarters.

Twilio is collapsing parallel generations of the same product - two Functions runtimes, SendGrid-era email versus Twilio Email - onto one platform, and simultaneously turning operational levers into API surface. Compliance is where that shows most clearly: consent, branded calling, and registration feedback are all becoming things you configure programmatically rather than things you file a ticket about. The deprecation notices and the certificate rotation share an audience of customers running old integrations, and Twilio is spending its changelog budget telling them what breaks and when.
Expect the migration cadence to continue through the September and October Functions cutover with follow-up notices on edge cases, and expect more of the compliance surface - the new TFV and A2P error codes already scheduled for September 15 - to land as API-readable signals rather than console-only state.
