Email channel

The email channel is a time-proven method of sending review invitations, and Reviewshake makes it easy for you to send your invitations over email. We use the same enterprise-grade email solution used by Uber, Spotify and countless other companies to improve your email deliverability.

Your invites are sent from by default, but you can easily send from your own domain by visiting the Advanced Setup tab of your Email channel page.

Pro-tip: Send your email invitations from your own email address

This involves adding three CNAME records to your DNS, which effectively gives us permission to send emails on your behalf. All emails are sent from shared IP address, and you have the option of sending from a dedicated IP address to control your sending reputation should you wish.


Use our template builder to setup your own email invitations, or setup your own custom templates by using HTML/CSS. You can use variables to inject variables such as the customer name, order ID as well as custom variables that you can provide us for each given customer.

We make it easy for you to A/B test which templates are delivering the best results - you can simply setup your trigger to run two or more templates simultaneously. You'll then be able to see high-level metrics such as click-through rates to double-down on the template that performs best.


Add an unsubscribe link to all your emails by adding the variable {{unsubscribe_link}} to your email, which will be populated dynamically for every email that gets sent.

Subject lines

Similar to Templates, you can also setup your own subject lines and use variables to customize them for each customer. Subject lines can also be A/B tested to improve overall open rates.
