Email preview tool

Preview Email Campaigns Across Devices Before You Send

An email preview is only useful if it shows the campaign you will actually send, with the data your recipients will actually have. Inbrovia previews the live document, not an exported copy, with real recipient values, on every device.

The difference

A preview that cannot go stale.

Separate preview tools work from a file you upload. By the time you fix something and re-upload, the preview and the campaign have drifted. In Inbrovia the preview is a step in the workflow, reading the same document you are editing.

Same renderer as the send

The preview and the send use one rendering engine. If it looks right here, it is built the same way for every recipient.

Real recipient data

Pick a recipient from your audience or a sample profile. Variables, fallbacks and conditional blocks resolve for that person.

Feeds the checks

What Inbox Lab shows, Campaign Guardian measures: mobile layout, contrast, alt text, link health and more.
Dark mode and images off

Preview the inbox conditions that break campaigns.

Dark mode and blocked images cause most of the layout complaints that reach a marketing team. See both before sending, on the same document, with one click.

Preview as a recipient

Different recipients, different emails.

A promotion that greets VIP customers and offers US shipping should look different for a Standard-plan customer in Australia. Preview both and confirm it.

Preview, then check

Seeing it is step three. Knowing it is ready is step four.

After the preview, Campaign Guardian runs its checks and produces a readiness score. Issues found in the preview are listed with a fix and open back in Inbox Lab.

Questions

About email previews.

Do I need to send a test email to preview?
No. Inbox Lab renders the campaign inside Inbrovia. You can still send a test to yourself from the Preview step when you want to see it in your own mail app.
Which devices are simulated?
Desktop at the campaign's content width, tablet at 600 pixels and mobile at 375 pixels, each with the responsive rules that mail apps apply at those widths.
Can I preview the plain-text version?
Yes. The plain-text alternative is shown alongside the HTML preview and can be edited before sending.
Can reviewers see the previews?
Yes. Approval links show reviewers the campaign on desktop, tablet and mobile, with the subject, preheader and sender.
