The Problem

Your Emails Look Fine in the Preview and Break in Outlook

Email clients don't render HTML the way browsers do. Classic Outlook for Windows uses Microsoft Word's engine, Gmail drops some styles, and dark mode recolors your design without asking.

  1. 01 · Outlook

    Columns stack into one strip in classic Outlook for Windows.

    We code with tables and Outlook-only fallbacks, then test in Outlook previews.

  2. 02 · Dark mode

    Your white logo disappears on a dark background.

    Logos, text, and buttons get dark mode versions checked before launch.

  3. 03 · Free templates

    Pasted template code breaks whenever someone edits it.

    Hand-coded modules with clear editable regions replace the patched free template.

  4. 04 · Editing

    Every campaign starts with an hour of layout fixes.

    Your team assembles campaigns from tested modules in the platform's own editor.

You built the newsletter in your email platform's drag-and-drop editor, and it looked right in the preview. Then a customer forwarded a screenshot. In classic Outlook for Windows, the two columns stacked into one long strip and the buttons lost their rounded corners. In Gmail on a phone, your white logo vanished against a dark background. Someone pasted in free template code, and now nobody wants to touch it. Every campaign starts with an hour of fixes, so the team sends fewer emails than planned.

We start with your brand and the emails you actually send: newsletters, launches, receipts, and flows. We design modules in Figma, then hand-code them with tables, inline CSS, and Outlook fallbacks, often through MJML. Every module gets tested in 30+ inbox previews in Litmus or Email on Acid, in light and dark mode. Then we set the modules up in your platform as editable blocks. Rendering bugs get found in testing, not in your customers' inboxes.

  • Coded for real inboxes

    Tables, inline CSS, and Outlook fallbacks keep layouts intact in Outlook, Gmail, Apple Mail, and Yahoo Mail.

  • Dark mode planned in

    Logos, buttons, and text colors get checked in dark mode before your first send.

  • Modules your team edits

    Each section becomes a reusable block in your email platform, so new campaigns need no code.

Our HTML Email Template Development Process

From Brand Kit to Tested Templates in Five Steps

You approve the module list first, then the Figma designs, then the coded templates in inbox previews. Nothing reaches your email platform until you've seen it in Outlook and Gmail.

  1. We look at your last 10 sends, your email platform, and your brand kit, and list where layouts break today. You get a module list, a template count, and a fixed price before any design starts.

What's Included

What You Get With Our Email Template Design Services

Each project covers module design, hand-coded HTML, dark mode, inbox testing, and platform setup, so your team sends from custom email templates that are already proven.

  • Branded module designs

    Headers, hero blocks, product grids, and footers designed in Figma to match your website and brand kit.

  • Hand-coded email layout

    Table-based layout with inline CSS and Outlook fallbacks, written by a developer instead of exported by a builder.

  • Dark mode versions

    Logos, text colors, and buttons adjusted so they stay readable when Apple Mail, Gmail, or Outlook switches themes.

  • Inbox and device testing

    Previews across 30+ inbox and device combinations, with screenshots of every result for your records.

  • Editable platform modules

    Templates set up in Klaviyo, Mailchimp, HubSpot, or your platform, with text and images editable without code.

  • Module guide and handoff

    A short guide to each module, plus the Figma files and coded templates delivered to your accounts.

Compare Options

DeveloperLook vs Free Template vs Platform Editor

A free template costs nothing, and your platform's editor is quick for simple sends. An email design agency costs more, so here's where each option holds up once Outlook and dark mode get involved.

What Our Clients Say

What Clients Say After Launch

Feedback from teams we have designed and built brand websites for.

We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Work Culture

Why Marketing Teams Trust Us With Their Email Templates

Email design services only pay off when every send looks right and your team stays in control. These are the habits that make us an email design agency teams keep.

  • Tested where customers read

    We check every module in real inbox previews, including classic Outlook for Windows and Gmail on phones. Your customers see the design you approved, not a broken fallback.

  • Accessible by default

    Templates use live text, a set reading order, alt text, and readable contrast. Screen reader users and people who block images still get your message.

  • Light on images

    We keep key words out of images and compress the images we do use. Emails load faster on mobile data and still make sense when images are off.

  • Honest about free templates

    If your platform's built-in templates already cover your sends, we'll tell you before we quote. Custom code pays off once Outlook issues or brand rules start costing you time.

  • Guides your team uses

    Each project ends with a short module guide showing what goes where and what not to change. New team members build campaigns without asking a developer.

  • Your files, your accounts

    Figma files, coded HTML, and platform templates stay in your accounts. Any designer or developer can pick them up later without a license fee.

Good fit

  • Ecommerce brands sending from Klaviyo

    Your launch emails need product grids, discount blocks, and reviews that match your store, and the default Klaviyo layouts look like every other brand's.

  • Teams looking for an email designer

    You've searched for an email designer who can also code, because your last designer handed over mockups nobody could build in your platform.

  • SaaS teams sending from HubSpot

    Your product updates and onboarding emails go out from HubSpot, and each one gets rebuilt by hand because there's no shared module library.

  • Publishers with a weekly newsletter

    You need email newsletter design services for a weekly issue with sections, sponsor slots, and article cards that editors fill in without touching code.

  • Agencies with email overflow work

    Your agency sells email programs and needs an email design company to code client templates under your brand while you run strategy.

Not a fit

  • Need monthly campaigns

    You want someone to plan and send campaigns every month, not just build templates. Our Klaviyo Agency for Shopify Stores page covers ongoing email marketing.

  • Only Shopify notifications

    You only need Shopify's order, shipping, and refund emails restyled. Our Shopify Email Templates page covers those built-in notification messages.

  • Mailchimp sync problems

    Your templates look fine, but contacts, tags, or store data don't reach Mailchimp correctly. Our Mailchimp Integration Services page fixes the connection itself.

  • Budget under $450

    Your budget is under $450 and you send a simple, text-led newsletter. Your platform's built-in templates will cover it, and we'll say so.

FAQ

Frequently Asked Questions

Straight answers on cost, timelines, Outlook and dark mode, and editing templates in your email platform.

  • Our email design agency starts custom email template work at $450 for one design, coded and tested in 30+ inbox previews. A modular kit with up to 15 reusable modules starts at $1,300, and a full system with 30 modules and 2 platforms starts at $2,700. You get a fixed price after a free review of your current emails.

  • One email template takes 5 to 10 business days from approved brief to platform setup. A modular kit or a full system takes 3 to 6 weeks, mostly because each module goes through design approval and inbox testing. Quick feedback on the Figma designs is the biggest factor in hitting the shorter end.

  • Email template design is planning and styling a reusable layout for newsletters, promos, or receipts, so every send follows the same structure. The design also has to respect how email gets coded: tables, inline styles, and a short list of safe fonts. A layout that ignores those limits looks fine in Figma and breaks in Outlook, so we design and code together.

  • The best email templates use one column on phones, about 600 pixels on desktop, live text, and one clear button. Add web-safe fallback fonts, keep key words out of images, write alt text, and check contrast in light and dark mode. Then test each new module in real inbox previews before it goes into a campaign.

  • Yes, design is critical in an email template because it decides whether readers spot the offer and the button quickly. A clear hierarchy, readable type, and one main call to action matter more than decoration. The design also has to survive Outlook, Gmail, and dark mode, so we treat layout and code as one job.

  • An email design system starts with a fixed set of modules, type styles, colors, and spacing rules, each coded once and reused everywhere. We document the modules in a Figma library and a short style guide, then save them as blocks in your email platform. New modules go through the same review, so every team's emails stay consistent.

  • Yes, every template we build gets tested in classic Outlook for Windows, which renders HTML with Microsoft Word's engine. We lay out modules with tables, add Outlook-only fallbacks for buttons and background images, and avoid CSS that Word ignores. The new Outlook for Windows renders more like Outlook.com, and we test both.

  • We set up templates in Klaviyo, Mailchimp, HubSpot, Campaign Monitor, and Salesforce Marketing Cloud. Each platform handles custom code differently: Mailchimp uses editable regions in its template language, while HubSpot uses coded modules in its design manager. We match the setup to your editor, so your team keeps editing in the tool it already knows.

  • Yes, your team edits text, images, links, and buttons in your email platform's editor without touching HTML. Layout and styles stay locked inside each module, so a rushed campaign can't break the design. A short guide shows which modules suit which emails.

  • Yes, you own the Figma files, the coded HTML, and the templates set up in your platform, with no license fee. Each plan includes 14 to 45 days of fixes after launch. After that, we can add modules when you need them, or any developer can extend the code.
