I created a template in Zoho CRM and used the    ${Contacts.First Name} code to personalize the email. I sent this out to 100+ clients. We had a client email us back because his name was incorrect. The clients name is Mike and the email he received was  Ramón . Do you know what could have happened and how we can prevent this in the future? 

Also, when sending a mass email, why does the email not show up in my sent items? 

Thanks.
