To be able to connect with the Zivver SMTP Gateway, a Connector is used to submit the sent messages to the Zivver SMTP Server.

Before you create a connector, send an email to enterprise@zivver.com to request your domain to be added to the so-called Zivver SPF allowlist. This is necessary to make a connection from Google Workspace to the Zivver SMTP Server.

With Google Workspace, only one send connector can process an outbound message. Thus, make sure that you know in advance which send connectors are configured in Google Workspace. It might not be possible to implement a custom relay. This is the case if it is necessary that a different specific send connector also processes the sent Zivver messages. For this limitation, you can send your use case to enterprise@zivver.com.

Do these steps to create a Connector in Google Workspace:

1. Login at the Google Admin portal with your admin account.
2. Click on apps Apps.
3. click on Google Workspace.
4. Click on Gmail.
5. Click the Hosts card.
6. Click ADD ROUTE.
7. Give the route the name Zivver Send Connector.
8. Under 1. Specify email server, leave the Single host dropdown menu on the option Single host.
9. At Enter a host name or IP enter smtp.zivver.com.
10. At 25 enter 587. This is the port that will be used.
11. Under 2. Options, leave the option Require mail to be transmitted via a secure (TLS) connection (recommended) checked.
12. Under Require mail to be transmitted via a secure (TLS) connection (recommended) leave the sub-option Require CA-signed certificate (recommended) checked.
13. Under Require CA-signed certificate (recommended) disable the sub-option Validate certificate hostname (recommended).
14. Click SAVE.

The connector is created and ready to use.
