Hello, 

We would like to create a funnel that measures:

N° of emails sent -> N° of emails opened -> N° of emails responded

We would like to measure this email response conversion rate for each of our SDRs. We use the analytics tool of Zoho CRM and not Zoho Analytics. 

We should probably create a funnel for this. However, we are confused because we can not choose the attribute "created time - email" for the lead module as we would expect it:

Looking forward to your help! 

Best, Sören
