SXX Mail Studio

Design an email from typed blocks, let the AI draft or edit it, and export the compiled HTML: table layout with Outlook VML buttons, a dark-mode stylesheet and a plain-text mirror. The canvas shows the exact HTML that is exported and test-sent. A preflight checklist flags what would get the email clipped, flagged or non-compliant — Gmail's 102 KB limit, a missing postal address or unsubscribe link, placeholder links and images, missing alt text — before you send it.

WHO IT IS FOR

  • Growth leads and marketing teams creating responsive promotional broadcasts
  • SaaS founders automating onboarding sequences and product announcements
  • Developers tired of fighting Outlook Word HTML bugs and Gmail clipping

WHAT YOU CAN BUILD

  • Bulletproof table and VML markup compatible with Outlook 2007–2024 and mobile Gmail
  • Dark mode color scheme overrides and Outlook.com [data-ogsc] twins
  • Automatic clean plain-text mirror for high deliverability
  • A test send of the exact HTML to your own account inbox

KEY CAPABILITIES

03 ENTRIES
01

Spec-first bulletproof compiler

The AI writes a typed block specification, never raw HTML; a deterministic compiler turns it into table structures, ghost tables for Outlook and VML buttons. Text formatting passes an allowlist, so nothing executable reaches an inbox.

02

Preflight before you send

A live byte counter for Gmail's clipping threshold and a checklist for the postal address and unsubscribe link, placeholder content, alt text and spam-prone phrasing. They are static checks of the email itself — they do not claim to predict inbox placement.

03

Multi-ESP merge tag export

Export production-ready HTML with one-click conversion to Mailchimp, Klaviyo, Brevo, SendGrid, or Resend merge tags.

NOTEThese describe what the generator produces for a brief of that shape. Output varies by run — the specification is planned each time, not retrieved from a template.
