Test rendering, accessibility, and delivery in one email QA workflow
Preflight gives developers and marketing teams real client previews, accessibility audits, and delivery checks in one place so every send goes out with confidence.
“I've been working with our internal AI QA agent for the past couple of weeks so my brain is in this space. Preflight is SO much better than our AI QA tool, so 👏👏👏👏”
How Preflight fits into your email QA flow
Move from draft to send-ready QA in one pass, without jumping between separate tools for rendering, accessibility, and delivery.
From draft to checked email in minutes.
Step 1
Send your draft
Input options
Send from your email provider to your private Preflight inbox, or upload HTML directly when you want a faster check.
Start with the draft you already have instead of recreating your email in a separate QA tool.
Step 2
Review what matters
One QA pass
See screenshots, accessibility issues, and delivery checks together so the team can spot problems without context switching.
Instead of running separate checks, your rendering, accessibility, and delivery signals stay in the same workflow.
Step 3
Send to your audience
Ready for your audience
Make the final call with confidence, knowing the important rendering, accessibility, and delivery issues have been checked before launch.
The goal is not just to finish QA, but to send knowing your audience will receive the email you intended.
