    A few weeks ago I wrote about Flodesk connecting to Claude and ChatGPT, so you can now ask your AI a question about your email marketing and get a real answer pulled from your actual account. That one changed how I analyze my sends.

    Today they shipped something arguably bigger. Flodesk Studio.

    It's a standalone AI email design app. But it's not another AI assistant. It's not trying to replace designers.

    Flodesk actually describes Studio as a place to create. That's not marketing spin. Once you use it for 20 minutes you realize the distinction matters. And it's why I ended up using it to build the first issue of a brand new newsletter I've been sitting on for months: Bad Marketing.

    I'll walk through what Studio is, what I built, what stood out, and who I think should try it.


    Design here. Send anywhere.

    The single smartest decision Flodesk made with Studio is that it works with any email provider.

    You can design your email in Studio, then send it through Flodesk, or you can export the HTML and send from Mailchimp, Kit, Beehiiv, ActiveCampaign, or whatever ESP you're currently on. Switching platforms isn't the price of a beautiful email.

    That's a big move. Most AI design tools are built to lock you into one ecosystem. Studio is built to work with the stack you already have.

    For creators like me who have opinions about deliverability, list ownership, and workflow, that flexibility is the difference between a tool I'd recommend and one I'd tell people to skip.


    What Flodesk Studio actually is

    Studio is a brand new AI email design app built by real designers and accelerated by AI. Not the other way around.

    Here's how it works:

    • You import your brand: logo, hex colors, custom fonts, imagery, button styles, and brand voice.
    • If you're already a Flodesk customerAffiliate, your existing brand kit pushes into Studio for near-instant setup.
    • You describe what you want to build.
    • Studio gives you a professionally designed starting point built on a design system created by human designers in Barcelona, Vietnam, and California.
    • You refine it. Either by prompting Studio in chat, or by jumping into the full manual builder and editing every pixel yourself.

    The result: your finished email looks like your brand, not like AI slop. Because the design foundation was built by people who obsess over small business aesthetics, and the AI just applies that foundation to your brand and your prompt.

    There's a quote from Dawn, one of the early testers, that stuck with me: "I forgot it was AI." After using it myself, I get why she said it.

    Studio is also standalone. It doesn't disrupt anything about your current Flodesk account or workflow. It's a separate app that any email sender can use, even if you're not on Flodesk.

    And right now, it's completely free while it's in beta. No credit card. No trial timer.


    Why "a place, not an assistant" actually matters

    Flodesk spent the last year building Studio quietly while the rest of the industry got loud. Every AI email tool released in that same window has positioned itself as a copilot, a helper, an assistant. Studio's team went the opposite direction.

    Their CBO Natalie said it best: "We don't want AI making the art for us. We want it to tear down every barrier between us and the joy of making something ourselves."

    That's not a slogan. That's a real product philosophy, and you feel it the first time you use it.

    Studio doesn't try to be smart at you. It gives you a starting point that already looks like your brand, then hands the mouse back. Real designers craft the foundation. AI applies your brand. You finish it and make it pixel perfect by hand.

    That's the sequence. And it's the sequence a lot of us have been asking for from AI tools for two years now.


    My actual test: building the first issue of Bad Marketing

    I've been sitting on a newsletter concept called Bad Marketing for months. It has 6,106 subscribers on LinkedIn — although, technically, LinkedIn owns them.

    Some quick backstory: over the last year I've been posting content on LinkedIn that generates a lot of engagement, and a lot of comments calling it "rage bait." Instead of arguing about it, I leaned into the label. Bad Marketing is a weekly breakdown of the campaigns, ads, creator content, and viral moments people love, hate, or can't stop arguing about. Why they worked. Why they didn't. What operators can steal from them.

    Originally I was going to publish it as a LinkedIn Newsletter. But then I caught myself.

    I've spent years telling businesses they don't own their audience on social media. Why was I building my newsletter on someone else's platform?

    LinkedIn owns the audience. LinkedIn owns the data. LinkedIn owns the distribution. I don't.

    So I decided to move Bad Marketing to email. And Studio is what I used to design the first issue.

    Studio's brand setup: colors, fonts, buttons, and voice all live in one place before you design a single email.

    The first thing I did was import my brand. Logo. Colors. Fonts. Button styles. Brand voice. Studio picked up on all of it. What I appreciated: Studio isn't trained on my customer data. It's built on Flodesk's own human design system. AI just accelerates the process while keeping me in complete control.

    Brand voice for Bad Marketing: editorial, opinionated, evidence-based. Studio references this every time it drafts copy.

    Then I gave it a prompt:

    "Create the first issue of my Bad Marketing newsletter introducing the concept, explaining why I'm moving from LinkedIn to email, and inviting readers to subscribe."

    Studio's generated first draft of the Bad Marketing intro email
    The first draft, generated in seconds. Yellow-and-black brand, real subject line suggestions, real copy — not a generic template.

    The first draft came back in seconds. And here's what surprised me: it didn't look like a generic AI template. The colors felt right. The typography felt right. The spacing was intentional. Someone had thought about the design system underneath before the AI got involved.

    I made a few edits by hand. Changed a headline. Swapped a hero image. Tightened some spacing. Then I switched to chat mode.

    "Make this headline more bold and conversational."

    Done in a few seconds.

    "Shorten this section and make it sound more like Carlos Gil."

    Done.

    Then I jumped back into the builder to nail the final details manually.

    That's the balance I've been looking for. Prompt. Refine. Perfect. All three in one place.


    What stood out after a full workflow

    Five things I keep coming back to after building the Bad Marketing issue.

    Brand Capture. This is the biggest differentiator. Instead of handing AI a blank slate, Studio learns your logo, colors, custom fonts (which you can map to Studio's system), imagery, button styles, and brand voice. The result feels like your business, not everyone else's.

    Speed. What used to take me an hour now takes a few minutes. Not because AI replaced me. Because it removed the parts I don't want to do anyway.

    You can edit however your brain works. Some people love prompting. Others want full manual control. Studio lets you do both, in the same file, without penalty. Prompt gets you 90% of the way. The last 10% is you.

    HTML export. I don't think enough people are talking about this yet. You can build in Studio and send from any ESP that supports HTML. Mailchimp, Kit, Beehiiv, ActiveCampaign, GetResponse, whatever. You're not locked in.

    It's built for creators, not enterprise teams. Consultants. Coaches. Small businesses. Solo operators. People who wear multiple hats and don't have four hours to design one email.

    The finished email doesn't look like AI made it. It looks like a designer helped me bring my idea to life. That's the exact distinction that separates Studio from every other AI tool I've tested this year.

    Who should try Flodesk Studio

    If you send email for a living or as part of your business, you should try it. Specifically:

    • Creators who want their emails to look like their brand, not like a Mailchimp template.
    • Coaches, consultants, and freelancers who don't have time to become designers.
    • Small businesses that want professionally designed emails without hiring a designer.
    • Anyone who's ever stared at a blank email builder for 20 minutes wondering where to start. Studio removes that anxiety without removing your creativity.

    You don't need to be a Flodesk customer to use it. That's worth repeating. If you're on Mailchimp, Kit, Beehiiv, or any other ESP that accepts HTML, Studio works for you too.
