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

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

In Google Workspace, only one send connector can process an outbound message. Therefore, make sure you know in advance which send connectors are configured in your environment. It might not be possible to implement a custom relay, for example, if another specific send connector must also process Zivver messages. If you’re affected by this limitation, send your use case to enterprise@zivver.com.

Follow these steps to create a connector in Google Workspace:

1. Log in to 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. Name the route Zivver Send Connector.
8. Under 1. Specify email server, leave the Single host dropdown menu set to 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 now created and ready to use.
