HTML Email Generator

Transactional emails from your app

Engineers shipping account-management features regularly need templates for password resets, signup confirmations, order receipts, and shipping notifications. Writing these from scratch means wrestling with Outlook's table requirements, Gmail's clipping rules, and Apple Mail's dark-mode quirks. Starting from a known-good template saves hours. Generate the HTML, paste it into your Resend or Postmark template, and your transactional emails immediately look polished without bespoke design work.

Newsletter design without a marketing tool

If you're sending a newsletter through a service that gives you an HTML field (Buttondown, Substack's API, self-hosted listmonk), you need to bring your own template. The "newsletter" template here gives you a clean, readable layout with a single accent color, conservative typography, and a CTA button — exactly what a successful indie newsletter looks like. Drop your content in, swap the brand, and you have a custom-looking newsletter without paying for a heavy ESP.

Product launch and update emails

Product teams shipping new features regularly need announcement emails that look intentional. The "announcement" template is built for this: a strong headline, a short body, a single CTA. Use it for launches, ship notes, milestone announcements, and migration notices. The dark header bar with a color accent ensures the brand reads immediately, even in a crowded inbox preview.

Promotional and seasonal campaigns

Sales emails live and die on visual impact. The "promo" template gives you a high-contrast headline area and a prominent CTA — the two things a promotional email needs to do well. Pair it with a strong subject line from our subject line generator and you have a campaign-ready email in five minutes instead of five hours.

Demos, mockups, and design reviews

Designers and product managers pitching new email flows often need to render a believable mockup quickly — for a stakeholder review, a Figma prototype, or a screen recording. Generating real HTML and screenshotting the preview produces a much more convincing mockup than a flat Figma mock. The live preview here renders inside a sandboxed iframe, which keeps your real DOM untouched while still showing exactly how the email will appear when sent.

HTML email button generator: bulletproof CTAs that render everywhere

Buttons are the single most rendering-fragile element of an HTML email. The CSS button you'd write for a website (border radius, padding, hover state) gets stripped or warped by Outlook, occasionally by Gmail's mobile clipping, and unpredictably by enterprise spam-filter rewrites. The pattern that survives — sometimes called a "bulletproof button" — uses a nested table with explicit pixel padding, a background-color on the inner cell, an anchor tag with display:block, and VML fallback for older Outlook versions. An HTML email button generator that knows this produces the full markup, ready to paste. Every CTA in the templates this tool outputs uses the bulletproof pattern by default. Rendering can still differ across Gmail, Outlook, Apple Mail, mobile apps, and security gateways, so client testing remains necessary.

HTML email template generator: starting from a known-good base

Writing an HTML email from scratch is a graduate-level exercise in inconsistent rendering. Better practice: start from a known-good template and modify. An HTML email template generator gives you a conservative base with table structure, inline styles, and media queries already correctly assembled. From there, you edit content rather than markup — change the headline, swap the body, adjust the accent color, then test the result. The five templates included (welcome, newsletter, announcement, receipt, promo) cover several common operational and marketing uses. Pick the closest match, customize it, and validate it in your sending system. The exported HTML can be taken to services like Resend, Postmark, and SendGrid, and pastes cleanly into ESP HTML editors (Mailchimp, ConvertKit, Klaviyo).
