Some launches add a feature. This one changes how you work.

The AI Agent builds entire campaigns from a single prompt. Goals, LLM Actions, Universal Search, WhatsApp, LINE, and a full UI redesign also shipped today.

Eight new capabilities. One platform that gets smarter every time you use it.

Join our live walkthrough April 16 to see it all in action: https://t.co/ln1ZGsd6iH

Maybe one of the biggest points of AI overwhelm is knowing just how much AI can do.

We like practical, tactical advice, so we're getting together a group of marketers to show exactly how they're using AI in their workflows and customer journeys.

On June 17, we'll talk through:

✦ How marketers are building audiences and segments with AI, and where it actually saves them time

✦ Prompts that go past "make this sound more human" into campaign logic and journey decisions that adapt on their own

✦ Real personalization, routing, and automation use cases from our team and from customers Monarch and KORSIT

✦ A live Q&A to get your specific questions answered

Never thought I'd end up playing space invaders instead of working on a product newsletter but here we are... it was actually a nice little interruption thanks @CustomerIO @alphacolin 😁

https://t.co/frLEWgiP92 now has a CLI and MCP server—meaning you can create campaigns, manage segments, trigger broadcasts, and query customer data directly from your terminal or from inside Claude, Cursor, and Codex. No UI required.

For technical marketers and growth engineers, it means your messaging infrastructure finally lives in the same environment as the rest of your work. Same rigor, same review process, same tooling.

For developers shipping fast, it removes friction from day one.

Data storage is not the same thing as customer memory.

Event-driven systems answer: what just happened?
Memory-driven systems answer: given everything that's happened, what should happen next?

That difference is separates good lifecycle marketing from great lifecycle marketing.

New in https://t.co/frLEWgiP92: Goals

Define the outcome you care about and the platform maps every campaign that influences it, with live, people-based attribution from day one.

One goal connects to many campaigns. If five campaigns touched the same converted customer, that's one conversion—not five.

@patrickmoran @getinnermost @claudeai Sorry to hear this, Patrick! I passed this along to our team, and they have some updates they'll send your way today that will help with this!

We're incredibly proud of our #5 spot on Newsweek's Global Most Loved Workplaces this year. 🥳

And even prouder of the people who made it real. 💚

Fully remote. 30+ countries. More than half the team joined in the last year and the culture somehow keeps getting better.

We asked the team what working at https://t.co/frLEWgiP92 is actually like, and they shared what it takes to build a most-loved workplace.

See what they had to say: https://t.co/3FGqreSTnF

Model Context Protocol is reshaping how AI systems access context. For engineering teams building on top of it, the implications go deeper than most realize.

https://t.co/frLEWgiP92 VP of Engineering Paul Senechko is speaking at @Mixpanel MXP 2026 in San Francisco on May 12 on what this shift means in practice.

The https://t.co/JnsjJIFbH1 subscription center got an upgrade.

Jon Miller (Marketo's co-founder) is now openly competing with Marketo.

On the Ops Cast podcast in March 2026, he said the quiet part out loud:

"Marketo and HubSpot are 20 years old. Eloqua is 25 years old. Pardot is 18 years old... they aren't evolving for the [AI] era."

And on Adobe's stewardship of Marketo:

"Then Adobe acquires it, and the most senior person at Marketo is a director of product marketing... you treat this thing like a cash cow."

When the person who invented the category announces a stealth startup positioned as "an alternative replacement to the legacy vendors, including Marketo" — that's the narrative shift.

The legacy MAP era is over. We synthesized what practitioners are actually saying about Marketo, HubSpot, Pardot, https://t.co/cpJBMrQARf, ActiveCampaign, Eloqua, and more: https://t.co/wkYeCDVYnH
