Customer.io vs Zoho Marketing Plus: at a glance
What is Customer.io?
AI-agent push continues alongside steady workflow-polish releases
Customer.io just shipped its largest release in years on April 8 — an AI 'agent' that can act inside the product, LLM actions for in-campaign personalization, expanded WhatsApp and LINE channels, and a UI overhaul. The weeks since have been quieter follow-on work: AI-driven style generation in Design Studio, multi-account switching, and small but useful campaign-workflow flexibility. The product is operating on two clearly distinct tracks at once.
What is Zoho Marketing Plus?
Zoho Marketing Plus at four: a slow drip of module additions to keep marketers inside the suite.
The tracked feed is sparse — seven posts across four years — and dominated by anniversary and year-recap entries. The few real release posts show a consistent pattern: bolt new modules onto the unified marketing suite (landing pages, a collaboration tool, a unified marketing calendar in late 2024; Budget Board in late 2023). The most recent entry is a four-year retrospective, not a feature.

AI-agent push continues alongside steady workflow-polish releases
◆ Current state
Customer.io just shipped its largest release in years on April 8 — an AI 'agent' that can act inside the product, LLM actions for in-campaign personalization, expanded WhatsApp and LINE channels, and a UI overhaul. The weeks since have been quieter follow-on work: AI-driven style generation in Design Studio, multi-account switching, and small but useful campaign-workflow flexibility. The product is operating on two clearly distinct tracks at once.
◆ Where it's heading
The AI-agent push reads as a durable strategic bet rather than a one-off announcement — recent shipping keeps extending AI surfaces (Design Studio styles from a URL) and the underlying primitives that AI uses (journey attributes that LLM actions can write into). In parallel, the team is filling in long-standing workflow friction: changing campaign trigger type after creation, resetting message content without rebuilding blocks, juggling multiple workspace accounts. The shape of the roadmap looks like 'agent on top, workflow primitives underneath.'
◆ Prediction
Expect the agent's actuation scope to widen — more skills, more Routines for recurring tasks, deeper use of AI credits as a billing primitive — while the quieter QoL cadence keeps chipping at friction points marketers raise in support tickets.

Zoho Marketing Plus at four: a slow drip of module additions to keep marketers inside the suite.
◆ Current state
The tracked feed is sparse — seven posts across four years — and dominated by anniversary and year-recap entries. The few real release posts show a consistent pattern: bolt new modules onto the unified marketing suite (landing pages, a collaboration tool, a unified marketing calendar in late 2024; Budget Board in late 2023). The most recent entry is a four-year retrospective, not a feature.
◆ Where it's heading
Zoho is doing accretion, not reinvention. Each release widens the suite enough that a marketer would not need to leave for a point tool — landing pages instead of Unbounce, budgeting instead of a spreadsheet, calendar instead of Asana for marketing. The shipping cadence is unhurried because the moat is breadth across Zoho's broader stack, not pace.
◆ Prediction
Expect another bundled feature drop late in the year alongside a 2026 recap. The likely additions sit in the same accretion pattern — AI-assisted campaign drafting, deeper Zoho One cross-app handoffs, or analytics consolidation — but timing will be measured in quarters, not weeks.
