Review Restrictions & Limits control who is allowed to submit reviews, what content is collected, and how uploads are sized. Combined with the Email Blacklist and Product Blacklist, they form your first line of defense against fake, spammy, or low-value reviews. Review restrictions

​
Available settings

Who can write a review

Choose between:
  • Anyone — any visitor can submit a review (even non-customers)
  • Only buyers who received a review request email + API users — locks review submission to customers you explicitly invited, plus your integrations
Recommended: restrict to invited buyers for the highest-trust reviews. Combine with Verified Buyer Badges for maximum credibility.
When enabled, Yuko automatically masks email addresses and phone numbers found inside review text before publishing.
  • Protects customers who unintentionally share private info
  • Required for GDPR-compliant public review display
  • Does not affect the review’s rating or visibility
Sets the per-image size cap for photo reviews.
  • Defaults to 5 MB per image — fine for phone photos
  • Lower the limit (e.g. 2 MB) to speed up mobile uploads
  • Raise it (up to 15 MB) for stores where high-res detail matters (art, crafts, jewelry)
Files larger than the limit are rejected at upload with a friendly error message — they never hit your storage quota.
These live on their own pages:

Email Blacklist

Stop Yuko from emailing specific addresses or whole domains. Useful for internal inboxes, test accounts, and unsubscribers.

Product Blacklist

Exclude specific products from review collection — gift cards, services, discontinued SKUs, samples.
  1. Restrict submissions to invited buyers — blocks drive-by spam
  2. Enable personal information restriction — protects customer privacy
  3. Maintain the Email Blacklist — block known-bad addresses and disposable email providers
  4. Keep image size reasonable (3–5 MB) — balances quality and upload speed
This configuration mirrors how most high-volume merchants collect reviews safely.
