Agency questions
- Who is the Agency plan for?
- Studios and freelancers who build and QA emails for several clients. You get multiple seats, review links you can email to clients instead of attaching files, and room for your own branding on reports.
- Does Preflight replace real-device screenshot testing?
- No. Preflight runs static checks and labeled client simulations in your browser. It catches the bugs that cause most send-day problems in seconds. For pixel-exact screenshots from real Outlook and phone apps, pair it with a device-farm tool for final sign-off.
- Do my email files leave my browser?
- Audits, previews and fixes run in your browser. We never receive your code. AI explain sends it straight from your browser to OpenAI using your own key, and share links carry findings, checklist and comments inside the link itself — never your HTML.
- Does it work with Salesforce Marketing Cloud and Adobe Campaign?
- Yes. Pick the platform and Preflight understands AMPscript and Adobe tags, checks fallbacks and unsubscribe tags, and exports a clean bundle with scripts left intact.
- Can I start for free?
- Yes. The free plan needs no sign-up. Paid plan checkout is not open yet; everything in the app is usable today.
