An email preview tool, built into the editor.
See exactly how every email renders in light mode, dark mode, desktop, and mobile while you write — no test sends, no screenshot services, no surprises.
Everything a real email preview needs.
Light, dark, desktop, mobile — checked before sending.
Dark mode, side by side
Light and dark renderings sit next to each other in the editor, so inverted colors and invisible logos get caught early.
Desktop and mobile views
Switch between desktop and mobile widths instantly to confirm layout, type size, and buttons hold up on small screens.
Spam check before send
Every email gets a spam score alongside its preview, so what looks right also lands right.
Save what works
Turn any previewed email into a reusable template, so layouts you've already verified become your starting point.
Preview while you write, not after
Most email preview tools live outside your workflow — write, export, upload, wait. Audienceful renders previews inside the Notion-style editor as you type, so checking dark mode or mobile is a glance, not a separate step.
No extra design work
Catch spam problems with rendering problems
A pixel-perfect email that lands in spam still fails. Audienceful pairs every preview with spam testing — content flags, authentication checks, and a score — so visual QA and deliverability QA happen in the same pass.
How to stay out of spamRuns automatically before every send
Build emails that preview well by default
Audienceful templates and the AI email builder produce clean, lightweight HTML that renders consistently across Gmail, Outlook, and Apple Mail. Less custom code means fewer dark mode surprises to catch in the first place.
Working with email templatesClick anything, change anything
Half your readers open email in dark mode
Dark mode is no longer an edge case — a large share of subscribers read email with it enabled, and emails designed only for light backgrounds routinely ship with invisible logos, unreadable buttons, and harshly inverted colors. An email preview tool that shows both modes while you write turns dark mode email testing from an afterthought into a default, catching failures before any subscriber sees them.
Previewing inside the editor also changes how teams work: no exporting HTML to a third-party renderer, no sending test emails to three phones. Start from email templates that already render cleanly, then run the built-in spam check covered in keeping emails out of spam before every send.
Every inbox condition, previewed.
Rendering checked before a single send goes out.

Email preview tool FAQs
What is an email preview tool?
An email preview tool shows how your email will render across different conditions — light mode, dark mode, desktop, and mobile — before you send it. Audienceful builds this into the editor itself, so previewing happens while you write instead of as a separate testing step.
How do I test my email in dark mode before sending?
In Audienceful, the editor shows light and dark renderings side by side as you write. Common dark mode failures — black logos disappearing, forced color inversion breaking buttons — are visible immediately, with no test sends to a device required.
Does Audienceful's email preview tool cover mobile?
Yes. You can switch the preview between desktop and mobile widths instantly to check that columns stack correctly, text stays readable, and buttons remain tappable on small screens.
Do I still need a separate email testing service?
For most senders, no. Audienceful covers dark mode, device widths, and spam testing in one place, and its templates output clean HTML that behaves consistently across Gmail, Outlook, and Apple Mail.
