SendSay integration allows you to send emails through this provider using Bloomreach Engagement’s standard emailing mechanism.
## Setup process
**1. Obtain webhook callback URL from SendSay support**
To integrate SendSay with Bloomreach Engagement, you will need to approach the SendSay support and ask them to set up a webhook callback URL in the following format: `
<API Base URL>/integrations/sendsay/webhooks/<project_token>`.
**2. Find your API Base URL**
To find your API Base URL, go to `
Project settings` > `
Access management` > `
Afterward, you will be able to edit the callback URL directly in your SendSay account.
If you want to track multiple Bloomreach Engagement projects separately, you will need to create a distinct Sendsay account or sub-account for each project.
After Integrating with SendSay, you can look at [Default email settings](🔗) in order to change it to your default email integration.
With SendSay, list-unsubscribe works differently. SendSay does not allow Bloomreach Engagement to set its list-unsubscribe header. SendSay forwards unsubscribe requests to Bloomreach Engagement by callbacks, which must be set up within the SendSay settings. Because list-unsubscribe is implemented within SendSay ESP, it is also responsible for updating its internal unsubscribe list.
