If you are sending emails through SEMSblast from your own Domain Name, it is a good idea to add something called an SPF Record to your Domain Names DNS Settings in order to ensure maximum deliverability.
An SPF Record is a setting that can be added to your Domain Name's DNS Settings which are usually available from the control panel of the company you purchased your Domain Name from.
All you need to do to setup SPF for SEMSblast is add a new SPF record to your domain DNS settings, using the following details:
v=spf1 a mx include:mpmserv.co.uk include:mpmserv2.co.uk include:mpmailserv.co.uk ?all
