Adds a Zendesk or external support address to your account. To add a Zendesk address, use the following syntax: `{local-part}@{accountname}.zendesk.com`. Example: 'sales-team@example.zendesk.com'. The [local-part](https://en.wikipedia.org/wiki/Email_address#Local-part) can be anything you like. To add an external email address such as help@omniwearshop.com, the email must already exist and you must set up forwarding on your email server. The exact steps depend on your mail server. See [Forwarding incoming email to Zendesk Support](https://support.zendesk.com/hc/en-us/articles/203663266). After setting up forwarding, run the [Verify Support Address Forwarding](#verify-support-address-forwarding) endpoint. The address won't work in Zendesk Support until it's been verified. #### Allowed For * Admins * Agents with permission to manage channels and extensions.
