email-template-generator

An email template generator produces HTML email markup — the cursed corner of front-end where <table> layouts are mandatory, inline CSS is the norm, and Outlook still uses Word's rendering engine. The ZTools Email Template Generator handles all that: pick a layout (single-column, hero+body, multi-column), add header, body, CTA buttons, and a footer; the tool emits Outlook-safe table HTML with inlined CSS, dark-mode hints, and bulletproof button code. Output renders correctly in Gmail (web + apps), Outlook (Mac + desktop + web), Apple Mail, Yahoo, Thunderbird.

Use cases​

Marketing campaign without a paid ESP​

A small business sends 5,000 emails a month from a self-hosted SMTP. Generator output renders correctly across clients without buying Mailchimp.

Transactional emails (welcome, password reset)​

Build once, reuse with placeholders ({{name}}, {{reset_link}}). Plug into any backend mail library.

Newsletter for a personal blog​

A weekly newsletter from a static site. Generator output is HTML that any mailer (Postmark, SendGrid, plain SMTP) accepts.

A/B testing layouts​

Generate two layouts; send to two halves of the list; compare open + click rates.

How it works​

  1. Pick layout — Single-column (mobile-first; renders well everywhere), hero + body, two-column with sidebar, footer-heavy. All max-width 600 px.
  2. Compose blocks — Header (logo + nav), hero (image + headline), body (text + image rows), CTA (bulletproof button), footer (address + unsubscribe). Drag to reorder.
  3. Style — Pick colours, font stack (web-safe + Google Fonts fallback to Arial), button radius, spacing. All CSS inlined into style attributes.
  4. Export — HTML output ready to paste into your mailer or save as .html. Optional plain-text alternative auto-generated.

Examples​

Input: Welcome email: hero + body + CTA + footer

Output: ~200 lines of table-based HTML, ~15 KB total. Tested in Email on Acid for Outlook 2016+, Gmail web/iOS/Android, Apple Mail.

Input: Plain-text alternative

Output: Auto-generated from the HTML — strips tables, preserves headings as ALL CAPS, indents lists. Sent as multipart/alternative for spam-filter friendliness.

Input: Dark-mode handling

Output: <meta name="color-scheme" content="light dark"> + per-element prefers-color-scheme overrides. Outlook ignores; Apple Mail and iOS honour.

Frequently asked questions​

Why tables and not divs?

Outlook 2007+ uses Word's renderer. Word doesn't support modern CSS layout (flex, grid, even floats reliably). Tables work everywhere — they're cursed but functional.

Does it work with all email clients?

Renders correctly in 95%+ of clients per Litmus client share-of-market. Outlook for Windows is the limiting factor — flexbox / grid / web fonts get quirky.

Can I send the email from this tool?

No — generator only. Send via your mailer (SendGrid, Postmark, SMTP, your CRM's send feature).

How big should the email be?

Under 102 KB to avoid Gmail clipping. Under 200 KB if you accept Gmail's "view entire message" link.

Does it support placeholders?

Yes — {{name}}, {{email}}, {{custom_field}} survive as plain text in the output. Most ESPs interpret them; with raw SMTP, run a templating step before sending.

Privacy?

All generation in the browser. Email content never uploaded.

Tips​

  • Always include a plain-text alternative — improves deliverability + serves accessibility.
  • Test in Litmus or Email on Acid before sending a campaign — Outlook for Windows is the most finicky client.
  • Keep total width 600 px and design mobile-first — most opens are on phones.
  • Use bulletproof buttons (table-based with VML for Outlook) — CSS-only buttons break in older Outlook versions.
