Issue Summary

Following the deprecation of the Send Email action, the Send customized email action is not returning all rules/flows that use it when filtering rules/flows.

Steps to Reproduce

1. Go to Settings -> System -> Global Automation
2. Filter rules by the Send Customized email action

Expected Results

It should return all rules that use that action.

Actual Results

It is only returning rules that used the Send Customized Email prior to the deprecation of Send Email.

• Old action key: outgoing.email

• New action key: action.send-templated-email

They still carry outgoing.email internally — so they simply don't match the "Send customized email" filter.

Workaround

Label the rules that use the Send Customized email action to be able to filter them more effectively.
