What is Customer.io?

After a summer of new send surfaces, the controls arrive: per-channel rate limits and send pacing.

Customer.io spent the summer widening where a message can land — geofence triggers, Live Activities, an in-app notification inbox, multiple mobile apps per workspace — and loosening who carries it, with Sinch, Infobip, and Vonage joining Twilio for SMS. The newest release turns to governance: per-channel rate limits on automations and API-triggered broadcasts, plus a wait-before-continuing step that holds a person in a journey until the message actually lands. The LLM layer picked up reusable knowledge sources, moving prompt context out of individual actions into a workspace-scoped library the Agent can also read.

What is Zoho Social?

Zoho Social opens its management surface to AI assistants via MCP.

Zoho Social's public feed is a marketing blog, not a changelog: most posts are anniversary notes and year-in-review recaps rather than shipped work. The two substantive posts in the visible window are Linkthread, a link-in-bio surface launched in March 2025, and an MCP server announced this week that lets an external AI assistant drive social media management. Between those, the feed goes quiet for months at a time.

7.5

After a summer of new send surfaces, the controls arrive: per-channel rate limits and send pacing.

◆ Current state

Customer.io spent the summer widening where a message can land — geofence triggers, Live Activities, an in-app notification inbox, multiple mobile apps per workspace — and loosening who carries it, with Sinch, Infobip, and Vonage joining Twilio for SMS. The newest release turns to governance: per-channel rate limits on automations and API-triggered broadcasts, plus a wait-before-continuing step that holds a person in a journey until the message actually lands. The LLM layer picked up reusable knowledge sources, moving prompt context out of individual actions into a workspace-scoped library the Agent can also read.

◆ Where it's heading

The pattern is surface-first, control-second. Each new channel widens the blast radius, and the rate-limit release reads as the answer to customers hitting the ceiling of their own sender reputation and downstream systems. Expect reach features to keep arriving paired with the guardrails that make them safe to switch on at volume — per-channel budgets, delivery-aware waits, activity logging on every new trigger type.

◆ Prediction

The next likely move is extending rate limiting and the wait-for-delivery step from automations to the remaining send paths, and giving geofences and live notifications the segmentation and reporting depth email already has.

3.8

Zoho Social opens its management surface to AI assistants via MCP.

◆ Current state

Zoho Social's public feed is a marketing blog, not a changelog: most posts are anniversary notes and year-in-review recaps rather than shipped work. The two substantive posts in the visible window are Linkthread, a link-in-bio surface launched in March 2025, and an MCP server announced this week that lets an external AI assistant drive social media management. Between those, the feed goes quiet for months at a time.

◆ Where it's heading

The direction visible here is Zoho Social moving from a place marketers work in to a system other software operates. Earlier AI work was in-product and generative — the 2023 Zia/OpenAI integration wrote captions inside the app. MCP inverts that: the assistant sits outside and the product becomes the tool it calls. Linkthread points the other way, toward owning more of the audience-facing surface, so the product is widening on both ends while its core scheduling loop stays stable.

◆ Prediction

The obvious next step is extending MCP coverage from publishing into the reporting and inbox surfaces, since those are the workflows the announcement frames as the burden. The feed is too sparse to say how fast that lands.
