The short answer
Choose Brew if you want to replace your email platform with one that also designs. Choose R10N if you want to keep Klaviyo, Omnisend or Mailchimp and have the emails designed for it, with unlimited brands and seats on every plan.
Both products start the same way: you give them your website, they read your brand, and they design an email from a prompt. They part ways at the end. Brew keeps your contacts and does the sending, so moving to it means moving your list, your automations and your sending domain. R10N stops at the finished email and hands it to the platform you already run, where your segments, flows and reporting carry on untouched.

Which one to choose
R10N fits when
- You already send from Klaviyo, Omnisend or Mailchimp and do not want to move your list or your flows.
- You want the email to look exactly as designed in every inbox, your own typefaces included.
- You design for several brands, or a team works on them together, and do not want to pay per brand or per seat.
- Your designer works in Figma, or your team plans in Claude or ChatGPT, and wants the emails there too.
Brew fits when
- You want one product for contacts, design and sending, and are happy to move to it.
- You need automations built and sent from the same place today.
- You want every email in live HTML text, for personalization inside the body.

Questions
Is R10N a Brew alternative?
For the design half, yes. Both read your brand and design emails from a prompt. If you want one product that also stores your list and sends, Brew is that and R10N is not. If you already send from Klaviyo, Omnisend or Mailchimp and want the emails designed, R10N is built for that.
Can I use R10N with Klaviyo instead of moving to a new email platform?
Yes. That is the point of it. R10N puts each finished email into your Klaviyo account as a campaign or a template, and your lists, flows, segments and sending history stay where they are.
Which one is cheaper?
They charge for different things. Brew's plans bundle AI credits with a monthly send limit, because Brew sends. R10N's plans are only for design, with unlimited brands and seats, and you keep paying your email platform for sending. Compare the two on how many emails you design and how many you send.
Why are R10N's emails images and Brew's HTML?
R10N's lead developer chose image-only so every email looks exactly as designed in every inbox, including Outlook, with no layout code for a client to get wrong. HTML carries more live text, which helps with personalization and gives inbox filters more to read. Our guide to image-only emails sets out the trade-off.
