Not able to send email body

Not able to send email body

Hi,

I have configured the following account with Zoho mail - info@homesanta.com. Whenever I'm sending a mail from the said email id, I'm able to send the full mail but the recipient is not able to view the body of email, they are able to view only the header and subject. I've added the MX records and SPF txt record. Is there anything else needs to be done?

Thanks
