Klaviyo‑ready emails from a link, your photos and your colors
Margarita Email Designer turns a brand's website, a folder of photos and a palette into finished emails: subject lines, copy in the brand's voice, client-safe HTML and a Klaviyo import zip. It never invents a product, a price or a review.
Voice, fonts, products and policies are read from the site
Logo, product shots and lifestyle images
Finished emails, ready to import into Klaviyo
An email designer that already knows your niche
Built on a library of 1,127 real emails from top DTC brands: which blocks they open with, how their subject lines read, how long their flows run. That method is packed into the skill so every email starts from what works.
You ask once. It reads, decides, writes and checks.
Reads the brand
It fetches the site, takes the voice from real sentences, finds the fonts and the products, and maps your colors to text, buttons and backgrounds with contrast checks. Anything it had to guess is listed for you to confirm.
Designs the email
It picks the occasion, the audience and the style that fits your niche, then writes two subject lines, preview text and copy that sounds like the brand. One idea and one button per email.
Checks before you see it
Klaviyo tags, legal footer, palette, dark mode, Outlook buttons, images-off reading, orphan words and spam phrases are checked in a real browser at desktop and phone widths.
Open the inbox. Every email is live HTML.
Pick a brand, switch its style, view it on desktop or a phone, and turn images off to see what Outlook users get, or switch to dark mode the way Apple Mail shows it. These are the real files the skill produces, not screenshots.
Ten brands, ten different emails
Hover or tap a phone to scroll the whole email. Every brand here is a demo; the photos are free stock.
The right email for the moment, with the facts it needs
Each preset knows its block order, timing and the facts it cannot run without. No real offer means no sale email. Mother's Day starts with an opt-out, because not everyone celebrates.
Popups designed for Klaviyo's own form builder
No code on your site. Each design comes with a build sheet: form type, list, timing, frequency, targeting, every step and the exact copy. SMS steps include the disclosure Klaviyo requires.
Every email is checked before you ever open it
Two built-in tools lint the HTML and render it in a real browser. An email that fails does not get delivered.
Klaviyo-correct tags
Unsubscribe, preferences, web view and address tags in the forms Klaviyo documents. Every name has a fallback.
Facts only
Prices, offers, reviews and policies come from the brand. Each claim is listed with its source.
Your palette, locked
Every color in the HTML is one of yours or a mix of two of them. Contrast is checked automatically.
Works in every inbox
Table layout, bulletproof Outlook buttons, dark mode, phone stacking and under Gmail's clipping limit.
Readable with images off
Headlines and offers are live text, and every photo has descriptive alt text.
No orphan words
Measured line by line at desktop and phone widths, so no heading ends on a lonely word.
No spam habits
Stacked exclamation points, filler and spam-trigger phrases are flagged before they ship.
Niche compliance
Alcohol, supplements, CBD, finance and kids get the claims rules their category needs.

Questions
Does it send emails or connect to my Klaviyo account?
No. It builds the files: email HTML, an import zip with your images, subject lines and notes. You import the template into Klaviyo and send it from there, so nothing reaches your list without you.
What if my site is down or I only have a logo?
It still delivers. It works from what you give it, uses text-led layouts when there are no photos, and lists every brand element it had to infer so you can check it.
Will it make up a discount or a review?
No. Offers, codes, prices, reviews, deadlines and stock claims only come from your site or your brief, and every claim is listed with where it came from.
Which colors does it use?
Only yours. Give it three (background, text and accent) and it derives the rest by mixing them, with contrast checked for every pair.
Does it work for flows, not just campaigns?
Yes. Welcome, abandoned checkout, browse abandonment, post-purchase and winback are built in, email by email, with timing and Klaviyo event tags.
Is it really free?
Yes. It is open source under the MIT license: use it for your own brand, your clients or your own tools. The code is on GitHub, and the docs explain every step.
