I have the following business requirements for sending email from Salesforce and I'm wondering if I can accomplish this by building custom components for the email application pane in Lightning:
Users are occasionally choosing the wrong email template and the wrong sent-from email address for important notifications. I need to either restrict the available email templates and sent-from address lists based on a field in the lead or opportunity object that the user is sending from or I need to validate these fields based on a field on the same objects before the email can be sent. I have not found a way to do either of these things using Salesforce Classic but it looks possible in Lightning.
Also, if there's a difference between what I can do with a Gmail or Outlook integration, please advise as it will help to determine an adoption decision.
Thanks in advance for any suggestions or advice on this.
