MxDelivery has all the info you need!

MxDelivery provides everything you need to confirm the proper configuration of your email delivery settings.


Google is now requiring SPF records before they will deliver your email to an inbox. MxDelivery checks for the presence of an SPF record, decodes the record in human readable tables and analyzes it against relevant RFCs. You will know how your SPF record looks to picky receivers like Google and how much of your email is passing SPF checks.


Google is also giving priority to companies that sign their email with a DKIM key. MxDelivery gives you insight into your DKIM key setup how much of your email is passing DKIM authentication.


DMARC is very important for receiving feedback about potential abuse coming from your systems. With a valid DMARC setup, you can receive feedback on the reasons why your email has been refused, giving you insight into potential issues and needed changes to policy. Add MxDelivery to your DMARC records to receive the best insight into your email delivery.
