What is the function of the "Send email via Gmail" option?

Question

What is the purpose of the Send email via Gmail option in the Email settings?

Answer

The Send email via Gmail option is only used by Zendesk support addresses that use the Gmail connector. If you see the text connected to Google Mail listed to the right of an external support address, then your support address is connected to the Gmail Connector.

If you have this option checked, all ticket and system notifications are sent from your Gmail, using Google mail servers instead of Zendesk mail servers. This means that you do not need to set up SPF or DKIM to authorize Zendesk Support to send an email on your behalf because the email is sent directly from your Gmail account. You can find all notifications in the Sent folder in your Gmail account.

Google has sending limits that restrict the number of messages sent per day and the number of recipients per message. If you approach the limit, you will receive a warning and notifications will temporarily be sent from Zendesk mail servers instead of Google mail servers.

Note: Enabling the Send email via Gmail option has no effect on your notifications if none of your support addresses use the Gmail Connector. Notifications will continue to send from the Zendesk mail servers. This option is only relevant if one or more of your support addresses is connected through the Gmail Connector.

Note: If you enable the Send email via Gmail feature, you can only use linked attachments. If you have attachments enabled, email notifications with real attachments are sent from Zendesk mail servers instead.
