Tool ComparisonDecision layer

ShowTrust vs Senja vs Trustmary (Agency Social Proof Stack Fit)

The split that matters is collection-first versus analysis-first: ShowTrust and Senja get proof onto the page quickly and cheaply, while Trustmary feeds the reporting layer that justifies a monthly retainer. Standalone collection tools drift toward commoditization because any competitor can install a widget in an afternoon, so agencies should pair whichever tool they pick with monitoring or response management to own the full feedback loop. Match the choice to what the client is billed for: display work favors ShowTrust or Senja, while a CX or reputation retainer favors Trustmary.

Which should an agency choose?

ShowTrust vs Senja vs Trustmary (Agency Social Proof Stack Fit)

white-label resale potentialcollection channel coverage (email, SMS, QR, import)feedback analytics depthper-client cost at 10 to 50 accountsdisplay and syndication surface

ShowTrust

Best for: Agencies that need a cheap, embeddable wall of love on client sites and already handle review monitoring elsewhere.
  • Flat $4.99/mo with unlimited testimonials on the free tier, so a 20-client retainer book adds almost nothing to tooling cost
  • Widget ships at roughly 5kb and inherits site fonts and colors, which keeps Core Web Vitals intact on conversion-critical pages
  • Full white-label means the collection page and wall can carry the agency brand rather than the vendor's
  • Collection is testimonial-first, so Google and Facebook review syndication needs a separate tool
  • No AI analysis layer for CSAT or NPS trend reporting

Senja

Best for: Agencies consolidating scattered proof from marketplaces and review sites before a site rebuild or campaign launch.
  • Imports testimonials from more than 30 platforms including Shopify, G2, Yelp, Trustpilot, and LinkedIn into one dashboard
  • Automatic video transcription turns customer clips into quotable text for landing pages and email
  • Partial white-label covers the collection form, which is the surface clients' customers actually see
  • Partial white-label leaves some vendor branding in the display layer
  • Import-first design assumes reviews already exist somewhere, so it does not solve cold-start collection

Trustmary

Best for: Retainers that sell feedback analytics and reputation reporting, not just widget installation.
  • Branded surveys capture CSAT and NPS alongside public reviews, so one send feeds both the client dashboard and the marketing page
  • AI analysis converts open-text feedback into themes an account manager can present in a QBR
  • Surfaces reviews in formats that improve visibility inside AI-generated answers
  • No white-label option, so the platform brand stays visible to clients
  • Survey-led flow adds a step before a public review lands on a third-party profile
