I can't seem to find a reputable GMP 3rd party Lab online. Is there a list of labs because my product was flagged due to not having this

Hired them as 3rd party, but wondering if they’re legit or cause for concern?

What is the latest policy on using these 3rd party Review solicitation services?

I understand Amazon's policy of not "harassing" customers - and that we're only allowed to ask for a review one time. These 3rd party services offer a way to "automate" clicking the "Request Review", although they send their own email template, etc. The biggest "value-add" they offer is being a little more smart about when they send the Review Request, and perhaps being able to reach a few people that might otherwise not receive a Review email.

G2G or steer clear?
