iPhone Mail Linking to Zoho CRM contacts

iPhone Mail Linking to Zoho CRM contacts

From what I can tell, if I am using a non-Zoho hosted email account (like Office 365, or standard IMAP/SMTP server) theye is no way to automatically capture emails I send from my iPhone Mail app to contacts in Zoho. the only way is to remember to BCC the special @mails1.zohocrm.com address every time? If that's the case, I wish the iPhone could be configured to automatically BCC that email address, but my iPhone only allows "BCC yourself" as an option.

Anyone figure out a workaround? If it helps, I am also using the Zoho CRM Outlook plug-in. thanks!
