    Hi,

    it seems that your domain embamg.com doesn't have SPF or DKIM records and because of this Gmail will reject your emails.

    Domains embamg.com MX-record points to > 0 embamg-com.mail.protection.outlook.com.

    Your SPF-record should look something like this "v=spf1 include:spf.protection.outlook.com -all". SPF-record specifies the source email servers that are authorized to send mail for the domain.

    I also reccomend that you setup DKIM and DMARC as well.
