Can I send one email to create two different tickets in two separate Zendesk accounts?
No, it is not possible to send one email to create or update two different tickets in two unique Zendesk accounts. Zendesk will create a ticket in the first account listed in the
TO: line and will reject the email sent to the second account's support address.
TO: email@example.com, firstname.lastname@example.org
A ticket will only be created in the account using the support email address company1.zendesk.com and will not be created in the account using the support email address company2.zendesk.com.
The same is true for multiple support email addresses used within the
CC:/BBC: field. Zendesk only identifies the first support email address used in the field.
