Everything between “design done” and “approved to send”.
Four jobs, one link: collect feedback, verify the details, route the approval, and keep the record.
Review & annotate
Reviewers click the email itself — the headline, the CTA, the logo — and their comment pins to that exact element. Threads, @mentions, statuses, version history with a cinematic compare, and a dark-mode simulator for Apple Mail, Gmail, and Outlook.
- Pixel-pinned annotations with threads and statuses
- Automatic version history + scrubbable compare
- Dark-mode preview for the three big clients
Approvals & guest reviewers
Send one link and collect sign-off from people who will never create an account. Multi-step routing, deadlines, password-protected links, a Kanban pipeline of every campaign’s state, and an audit trail of who approved what, when.
- Guests comment and approve with zero onboarding
- Multi-step approval routing + deadlines
- Kanban pipeline across every campaign

Link Visualizer
Every link in the email gets a numbered badge and a live screenshot of its destination — wrong URLs, dead pages, and stale UTM targets get caught in review instead of in the send report.
- Numbered badges drawn on the email itself
- Destination screenshots, titles, and HTTP status
- Comment directly on a link card

Email Cleanup
Gmail clips emails over 102KB. After approval, Proofel measures your HTML, flags inline-image bloat, then minifies and compresses in one click — so the campaign that got approved is the campaign that arrives.
- Size analysis against the Gmail clipping threshold
- One-click HTML minify + image compression
- Keeps Outlook conditional-comment fixes intact
