Cart Abandonment : Trigger Implementation

[ambikaTewari_ATCI]

Hi Experts,

We are planning to user Triggers inorder to trigger emails for abandoncart usecase.
As a part of the implementation, App Id has been generated at target end same has been shared with the Campaign Team.

Trigger is also created with below setup:

metric under "Visit must include" ---> Cart Additions

metric under "Visit must not include" ---> Purchase

Meta Deta : Product name (evar)

Do we need to define any conversion variable and success events like "email triggered" at analytics end for complete implementation of trigger ?

Any inputs in this regard is highly appreciated.
