Hey Product Hunt 👋

I'm Philip, co-founder and CEO of Brew. When I was leading US growth at Revolut, I kept seeing teams with world-class products fail at the last mile - actually reaching and retaining the users they'd worked so hard to acquire.

The fix was always email. It's still the highest-ROI channel for activating, nurturing, and retaining users - nothing else comes close.

But every time we tried to execute it properly, we ran into the same painful cycle. Campaigns that took weeks to build. Emails that broke in half our users' inboxes. Designs that didn't look on-brand. And when the pressure was on, they just didn't go out at all.

The problem wasn't the team. It was the tools.

Old school SaaS platforms like HubSpot, Mailchimp, and Marketo were built for companies with entire departments dedicated to running them. Someone has to analyze the data, plan the campaign, write the copy, design the emails, code the HTML, deploy it, and optimize the results.

For most teams that's just not realistic - so the software sits there underused and revenue gets left on the table.

My co-founder (former Vercel) and I built Brew to fix this.

You describe the campaign you want and Brew builds the whole thing in seconds:

  • Welcome flows and drip sequences

  • Newsletters and lifecycle campaigns

  • Multiple on-brand variants

  • Production-ready HTML that renders perfectly across Gmail, Outlook, and Apple Mail

It pulls your branding automatically from your website and Figma. What used to take even the best teams 8 days now takes one prompt.

It's like Claude Design or Lovable, but made specifically for email marketing (the emails render perfectly across inboxes because the underlying HTML is email-optimized, unlike Claude).

Watch me walk through it personally here:


A few things people are surprised by when they first try it:

  • It builds entire multi-step sequences, not just single emails

  • The brand extraction is scarily accurate

  • It works natively with Viktor, OpenClaw and any AI agent

  • You can push straight to Klaviyo, HubSpot, Mailchimp, or whatever ESP you're already on

This is just the beginning. We're building toward a full autopilot - you set the objective, Brew handles everything else. The goal is to become the new system of record for email marketing. One where going back to the old way is unthinkable.

Try it for free, break it, and tell us what's missing. Every piece of feedback goes straight into what we build next.

Thanks to and for building this with me and Thomas. And to the Product Hunt community - there's no better place in the world to launch something you've worked this hard on.

Much love,
Philip 🫶

       love the idea so we can now vibe on email design and automation as well right?

Maker

You got it . Vibe coding, but for email. Describe the campaign or the automation and Brew builds it end to end, on-brand and rendering right everywhere. That's why people call us "Lovable for Email Marketing" and "Claude Design for Email Marketing".

Appreciate you Mohsin! ❤️‍🔥

one-click integration to push campaigns straight to Klaviyo or HubSpot is critical for existing operations. When you push a generated multi-step flow t`o Klaviyo, does it map over as an editable drag-and-drop template blocks workspace, or does it export strictly as static custom HTML blocks?

Maker

Great question  , and one we get from operations-minded teams a lot.

Honest answer: today we push the flow into Klaviyo as a production-ready HTML block per message rather than as Klaviyo's native drag-and-drop template blocks. That choice was deliberate, since mapping into Klaviyo's editor schema means giving up the pixel-perfect output we generate, and most of our early users wanted "ready to send" over "ready to redesign."

The flow structure (triggers, branches, delays, audiences) does map natively to the Klaviyo flow editor, so you can still tweak logic and timing without touching the email itself.

That said, "editable in the drag-and-drop editor" is on our roadmap, since we hear this exact request from teams who want to make light edits without coming back to Brew. Would love to hear how you would use it. If you want, drop me a note at and I will keep you posted as that ships.

   

Philip,

This is actually the feature I’d be most excited to see.

I’ve spent a lot of time trying different AI email builders and ways to generate Klaviyo emails, and the biggest issue I keep running into isn’t creating the email—it’s being able to easily edit it afterward.

For our team, the ideal workflow would be Brew → Klaviyo → fully editable drag-and-drop blocks. Campaigns change all the time. Someone wants to swap an image, update a CTA, add a section, or make a last-minute tweak before a send. If the output is custom HTML, it becomes much harder for the rest of the marketing team to work with.

The ability to generate a campaig and then hand it off to the team to continue editing in Klaviyo would be huge.

I also think it would lower the barrier to entry for a lot of marketers. Not everyone knows HTML or wants to learn it, but most people are comfortable working inside Klaviyo’s editor. Even being able to push content into Universal Content Blocks would be incredibly useful!

That’s really the main thing I feel is missing right now, and I haven’t been able to find a solution

Would be happy to test it if you decide to build it. :) Thanks!

       Many congratulations Philip and team! :)


How I met the makers?


When the Brew team first reached out to me in early January 2026 to hunt their product, my very first question was: “How is this actually different from the other similar email tools I’ve seen launch on Product Hunt?”

I’ve hunted / endorsed quite a few “AI email” products already, so I went in with a healthy dose of skepticism.

But once I jumped into Brew, it clicked very quickly. The biggest utility for me was how naturally it works with AI agents and how opinionated it is about the last mile: getting production-ready, on-brand emails that actually render correctly everywhere, not just pretty mocks.

What is Brew and how it works?


You describe a campaign or multi-step automation in plain English and it doesn’t just spit out copy, it builds the whole thing... flows, variants, production HTML, and targeting logic, in seconds.

I also really like how simple and honest the positioning is: “Like Claude Design for email marketing.” It’s a straightforward promise, and the product delivers on exactly that, especially with the way it pulls your brand from your site / Figma and focuses on HTML that works across Gmail, Outlook, and Apple Mail.

Why I endorse Brew?

Where Brew stands out for me (and why I was happy to endorse it) is that it feels built for the reality of modern teams. You can plug it into whatever AI agent you’re already using, keep your existing ESP (Klaviyo, HubSpot, Mailchimp, etc.), and still get that “Claude Design-like” but purpose-built for email.

For teams that don’t have the luxury of a full email department, this is the kind of leverage that can make the difference between “we should send that campaign” and “we actually shipped it.”

Huge kudos to Philip and the team for focusing on every critical details of email marketing. If you care about shipping beautiful, on-brand emails and lifecycle flows without wrestling with templates for days, Brew is absolutely worth a serious look. :)

Maker

Thank you , this means a lot. ❤️‍🔥

I actually remember that first call in January and how skeptical you were, you had seen enough "AI email" launches to be tired of the category, and you grilled us on what made Brew different. So the fact that you came around to endorsing it carries real weight for us...

You captured the heart of it perfectly: the last mile is everything. Anyone can generate a pretty mock, but getting a production ready, on-brand email that actually renders right in Outlook is where it gets hard, and that is exactly what we obsess over.

Grateful to have you hunting us today. :)

       Congrats on the launch team. Lolled hard at "even outlook".

Maker

Thank you so much ! Anyone who has fought Outlook knows it is a genuine boss fight. "Even Outlook" is half a feature and half a trauma response. Thanks for the love. ❤️‍🔥

       Congrats on the launch, Brew looks intriguing! Thanks for the walk-through video, Philip, I was looking for it. The demo on a real customer content was especially useful!

Maker

Thank you so much ! Really glad the walkthrough was useful, and good to hear the real customer demo landed. We went back and forth on whether to use a live example or a polished fake one, and decided seeing it work on actual content was way more convincing. Appreciate you watching the whole thing.

 exactly! you know, demos on fake content are not always very representative, so they are not convincing. I watch such demos and go like, "ok and how will you handle something real?"

Maker

 I'm exactly the same! It was also really nice of to let us include this in our demo video. They're so cool and nice! ❤️‍🔥

Been a happy Brew user for some time now. Incredible team and beautiful UX; this is what modern email marketing should look like.

Congrats on the launch team!

When can we expect a Brew MCP so we can automate directly from coding agents or OpenClaw? :)

Maker

Thank you so much  , means a lot from a longtime user with a high standard! ❤️‍🔥

You are speaking our language. An agentic, chat first Brew is exactly the direction we believe in, and driving it from coding agents is part of that vision. I will not promise a date yet (we want to make sure it works 110%), but we're working on it as we speak. You will be among the first to know when there is something to play with. 💪

Maker

 Thank you for the kind words Ohans! And yes, we are building an MCP and expanding our API suite to enable all agents to leverage Brew :)

  would love my agents to find and buy Brew for each GTM strategy I run. Which goes beyond MCP, moves into MPP land. Would be happy to help guide you through this

Maker

Appreciate this ! Agreed it goes beyond MCP, agents discovering and buying autonomously is a real and interesting layer. We are focused on the MCP and API foundation first, but I would love to hear how you are approaching MPP.

Any time that works for you next week?

Congrats ! I love the demo video, inspiring to start building beautiful emails😻 How are you handling Outlook rendering under the hood? It is usually the hardest client to get right and most tools give up on it.

Maker

Thank you , really glad the video landed! 😻

Outlook is exactly the client that breaks most tools, so we put a lot of work into it. We have run a bunch of testing and evals across clients to find the approach that actually holds up everywhere, Outlook included. It comes down to a combination of things: compiling to bulletproof, client tested markup, handling the Outlook specific edge cases that other tools skip, and being deliberate about fonts and fallbacks so nothing silently breaks. The result is emails that just render correctly across Gmail, Outlook and Apple Mail without you having to babysit them. 🙌

wow! how deep does the brand extraction go? wondering if it picks up fonts and spacing or mainly color and logo.

Maker

 Hey Yurii! Great question. The brand extraction takes any link and does a comprehensive extraction of logos, images, colors, fonts, links, and brand information. We've spent a lot of time understanding what a "brand" really is and how we can consistently extract it to create on brand emails. We want your emails looking and feeling like the identity of your site. Give it a try and let us know what you think :)

Maker

 It goes deeper than most people expect. Here's an example of what Anthropic emails look like in Brew. The way we help LLMs understand the art and science of your brand is part of our "secret sauce" - spent late nights and weekends perfecting this ❤️‍🔥

The idea is really cool, i like the UI design as well
But here's some feedback from a first time user

- the onboarding UI seems cool but idk after i wrote my website in the field it asked to click enter and for some reason it was not detecting enter from keyboard and i needed to manually click the smallest enter button, lol
- i felt like it started bombing a lot of features at me at starting and i only wanted to explore the email design part for now and it created some kind of friction for me
- i gave it a detailed prompt on what i want and the results were below in the image, assuming it was caused due to some kind of outage due to sudden user spike i was left on with 0 results

Happy to try it later after sometime once this is fixed

 Hey Grover! Apologies for the subpar experience here, this is definitely not intended. Thanks for surfacing this with us and the detailed feedback as well :) We're fixing this now!

Maker

Hey 


Really appreciate this, this is the kind of feedback that actually makes the product better.

The zero results on your prompt was on us, not you, likely the spike you guessed at, and it should be sorted now. Mind trying again and telling me if it works? And if you are open to it, would you jump on a quick call with us founders?



Your first-time perspective is exactly what we want to hear, and we will drop a bunch of free credits in your account as a thanks. ❤️‍🔥

Maker

 Hey Grover! This has been fixed now. The issue was that we were capping the limit for messages at 2000 characters and your prompt was over it. We've now increased the character limit so detailed prompts like the one you sent should work perfectly. Thanks for bringing this up and helping Brew get better!

Maker

For anyone reading along - this is why I love working with my co-founder   . He's so customer-obsessed and his velocity is unmatched. Go give this man a follow:

I'm a happy MailerLite user, but looking at that gorgeous video I have to sign up and try the platform out! Congrats on the launch and the awesome execution :)

Maker

Appreciate it ! MailerLite is a solid tool, so that means a lot. Would genuinely love to hear what you think once you have tried it, especially coming from a tool you already like. Thanks for the kind words on the launch. 🙌

Awesome to see native compatibility with tools like OpenClaw and Viktor right out of the gate. For an automated multi-agent workflow, can we hook Brew up to run autonomously like having an agent analyze weekly database churn metrics and prompting Brew via API to generate a custom win-back sequence?

Hey Philip! It's super cool, cause agree it's still the highest-ROI channel. How is the business model here?

Maker

Thank you so much ! ❤️‍🔥

We have a really generous free plan to start, and our paid plans combine the email sending and the AI email creation in one place, so no stitching together a separate tool for delivery and another for design. For bigger teams we also do custom enterprise plans.

Our customers are saving A LOT of money using Brew 🤝

Solo founder here, building toward an App Store launch, and lifecycle email is exactly the thing on my roadmap I keep deferring because the tooling tax is real. So the "8 days → one prompt" promise lands.

Quick q: How deep does Brew go on tone? Can it learn a brand's voice from existing copy (site, past emails), or is it pulling visual identity and writing in a competent-but-generic marketing register underneath?

Maker

 Hey Ferdi! The brand extraction on your domain understands your marketing copy to ensure your emails match your tone. You can also adjust this with additional rules for the agent in the brand page. If you have a tone in mind Brew can copy it.

Best of luck with the app store launch!

You mention that open rate improves by 48%. But how does that work? Open rate depends on the subject line — a person will not see even the best design in the world until they open the email.

And how do you track open rate? For more than a year now, open rate tracking (via pixel) has been disabled by everyone who does this professionally because it is considered a very negative factor for Gmail.

Overall, the service seems quite useful, but the questions above are still unanswered :)

Maker

Hey - totally fair questions, and you clearly know this space. 💪

You're right on both counts:

  • On attribution: you are right that opens come down to subject line and sender reputation, not design. That is actually something we have worked on directly. We have spent time with some of the best email marketers in the world to understand what genuinely drives opens, subject lines especially, and built that thinking into the product. The catch is that it is highly dependent on your brand and the specific audience you are sending to, which is exactly what Brew takes into account rather than applying a one-size-fits-all formula.

  • On tracking: also fair. Pixel-based open tracking has been unreliable since Apple Mail Privacy Protection started pre-loading images, so we treat absolute open rate as a soft signal rather than a source of truth. Where it does stay useful is relative comparison: when you send to the same audience with the same tracking method, the noise is roughly constant on both sides, so the difference between a control and a redesigned send still tells you something real. Beyond that we lean on clicks, conversions, and replies, which are harder to game and not inflated by privacy proxies.

Appreciate you pushing on this. For full transparency, these numbers are from one of our customers, LiveFlow, rather than an aggregate across all users, so treat it as one real example rather than a guaranteed result.

Thanks for the thoughtful comment. ❤️‍🔥
