Online proofing tools for agencies: what to look for
By the Usertack Team · June 20, 2026 · 3 min read

Short answer
The proofing tool features that matter most for agencies are: no-account client access, support for every format you deliver, team visibility on comments and approvals, and a provable sign-off. Per-seat pricing and client logins are the usual friction points to avoid.
Start with client friction
The best proofing tool is the one your clients will actually use. If a client has to create an account or learn software, participation drops. Prioritise tools with a no-account review link—that single feature drives response rates more than any other.
Features that matter for agencies
- •Every format: live sites, images, PDFs, video, email, A/B.
- •Pinned comments anchored to the exact spot.
- •Team access so approvals aren't stuck in one inbox.
- •A certified sign-off you can show a client later.
- •Multiple brand profiles for a tailored client experience.
Watch the pricing model
Many tools charge per seat, which punishes you for growing your team. Look for flat or transparent team pricing so adding a teammate doesn't blow up the bill. Usertack's Studio plan includes three Creators and adds more at a flat rate, with clients always free.

Frequently asked questions
What should agencies look for in a proofing tool?+
No-account client access, support for every format, team visibility on feedback and approvals, provable sign-off, and pricing that doesn't punish adding teammates.
Are per-seat proofing tools worth it?+
They can get expensive as your team grows. Flat or transparent team pricing is usually better for agencies that add Creators over time.
Do clients need logins for proofing tools?+
The best tools don't require it. A no-account review link removes the biggest barrier to client participation.
