Relevant Products: Exclaimer Cloud - Signatures for G-Suite
You want to setup Exclaimer Cloud - Signatures for G Suite but would like to understand more about the implications on your existing third-party service's mail routing setup.
You have already configured Exclaimer Cloud - Signatures for G Suite alongside a third-party service and found that emails are routed directly to the third party and not to Exclaimer Cloud. Therefore, signatures are not applied to your emails.
It is possible to configure Exclaimer Cloud - Signatures for G-Suite to work alongside another third-party service.
To achieve this, it is necessary to ensure that emails are routed to Exclaimer Cloud first, and once the emails are delivered back to G Suite, the emails route to the other third party.
With G Suite, there are various settings (such as, Routing, Default Routing and Content compliance) that can change the route of an email. Google doesn't currently offer any settings within the Admin Console to prioritise any of these rules, however, the order in which they were created determines the order in which they are processed.
If you have mail routing options configured for another third-party service, it is necessary to remove them and recreate the Routing, Default Routing and Content compliance rules once the Content compliance rule for Exclaimer Cloud has been created.
