Trustindex’s Review Collector Email Campaigns are designed to automate the process of requesting customer reviews at the right moment, with minimal manual effort. Rather than relying on one-off email lists or manual follow-ups, Trustindex offers multiple automation methods that connect review requests directly to real business events such as invoicing, payments, or completed services.
In this article, we will discuss the available integration options for the Trustindex Review Collector Email Campaigns, so you can streamline your review collection practices.
How Does It Work?
Once a campaign is set up, Trustindex automatically sends review request emails based on predefined triggers and timing rules. Businesses can control:
- When review requests are sent (e.g. immediately or days after an event)
- Which review platform customers are directed to (including Trustindex itself)
- Email content, branding, and language
- The Intelligent Invitation System (optional)

Once the automation is active, campaigns run continuously without manual intervention.
Automation via Billing, Invoicing, and Payment Platforms

You Don’t Use Any of the Above?
If you don’t use any of the listed integrations, you can still collect reviews using the BCC option. Just add the unique Trustindex BCC address to any transactional, confirmation, or follow-up emails you send. When your customer receives the email, they’ll automatically be invited to leave a review through Trustindex. This makes it easy to connect review requests to any email conversation, even if your system isn’t directly supported.
