Please make sure you have connected seller central integration and given Zonmaster proper permission to view Order details.
In order for the automatic buyer-review matching feature to work, two conditions need to be met:
1) An email has to be sent prior to that order
We can still link up orders if you are currently using another email automation service, but please be aware many service providers do not send emails to every single order or have buyer opt out blacklists, this could significantly decrease the amount of reviews matched. Zonmaster logs and tracks every email that is sent out, so if you use Zonmaster for email automation we can provide support on reviews that don't match.
2) The review has to be a for a purchase that the customer must have bought from your store and not another competitor or store.
Also, the timing in which the matching occurs is not exactly when the negative review arrives. Zonmaster runs a separate script to collect and match the buyer order information. It can take anywhere from 1-12 hours for the match to appear.
There are also some other cases when the automatic matching may not occur:
1) The review that was left was from a really old order.
Product reviews can be left anytime after a purchase. When you first signup, Zonmaster will only buyer review match up to 5 weeks worth of past orders, meaning we collect only the customer ID's from your past 5 weeks emails, so if a person leaves a review and that purchase was made many months in the past, we will not link it. After you are a fully paid-up subscriber we may go back further for your orders and therefore be able to match reviews from older orders too (assuming you sent them emails)
2) Your current or previous email auto responder provider did not send emails out to all orders.
Some email auto responder services have a global blacklist, meaning they do not send emails out buyer-opt out customers. If no email is sent, the customer ID code cannot be extracted and the review cannot be automatically linked.
3) The order associated with the product review is a gift order.
Amazon does not provide us any buyer information for gift orders therefore Zonmaster does not send out emails to gift orders. If this is the case, then the customer ID code cannot be collected and a match will not occur if the review is left by that order.
We suggest in order to maximize the linking rate to orders, that you have an email campaign running that sends any type of email to all your orders. This will greatly increase the chances of a direct match. And if all orders have an email sent + its a verified purchase from your store, there should be close to a 100% match rate.
