I have Zoho One and my Zoho Partner has configured my mail client on the web site my g-Suite account.

He did this because I use Gmail as my email client but I'm happy to route it through Zoho as I am using Campaign and other programs and I'm concerned that if it's not set through Mail that I may be sandboxed as a spammer.

Is it best practice to have the web site MX DKIM and SPF pointing to Zoho and the integrating the CRM with Gmail to send and receive emails. At this stage I'm not intending to use Zoho Mail for my mail client (not yet)

If I do set it up this way will the G-mail emails still appear in the Lead/Contacts email section in their record and will it have any impact on using my G-mail calendar?

Thanks
