Hi Everyone - hoping someone might have a good idea or solution for what I'm trying to do.

In Journey Builder, I need a way to check if the Lead's email address has *transitioned to the Account object.

*I say 'transitioned' because the dev team, for whatever reason, chose to NOT use the standard Lead Convert functionality in SFDC.  Instead they developed/are developing custom Apex which, upon the web user viewing his cart...

• Apex creates an Account and populates Account.CustomEmailField__c with Lead.Email
• Apex also creates a Contact under the Account and populates Contact.Email with Lead.Email
• Apex also creates a ChildBelowAccount record, but that doesn't matter for the purposes of this.

So in Journey Builder... steps 1-4 I have all put together and ready to go.  Step 5 and/or 6 is where I'm hoping one of you MC experts here might be able to point me in the right direction.

1. Lead enters the Journey
2. Wait Time
3. Send Email #1 to Lead.Email  (let's say joe.shmoe@whatever.com)
4. Wait Time
5. Mechanism or Logic is needed here to check if Lead has transitioned to Account/Contact.  We don't want to send Email #2 to the Lead joe.shmoe@whatever.com if he's already transitioned to Account/Contact after Email #1 was sent.
6. Send Email #2 to Lead.Email  (only if Lead hasn't transitioned to Account/Contact)

Thank you in advance!
