The shared email (from advocate to friend) will include an unsubscribe link that will add the email address to a Friendbuy-maintained opt-out list, ensuring that they will not receive any further Friendbuy-powered referral emails. The reward email to the Advocate would not have an unsubscribe link as this is considered transactional.
Many of our clients consider the Friendbuy-maintained list to be sufficient, as the friend can be considered to be unsubscribing specifically from the referral program. However, we do have clients who have integrated with their own CRM/opt-out lists as well.
There are a few different ways that this can be integrated with your CRM:
You can supplement the Friendbuy-maintained list by:
Uploading addresses to the platform
You can also retrieve the latest opt-out list via API
Friendbuy can also optionally be configured to send a request to an endpoint maintained by your system before the shared email is delivered. The shared email will only be delivered if your system's endpoint authorizes Friendbuy to do so. You can read more about this here.
As always, please feel free to reach out to support@friendbuy.com or your Customer Success Manager for any additional information.
