About DNS Settings for Email Marketing

If you are sending a lot of marketing email, say 10,000 a month or more, you can improve your Sender Reputation and therefore deliverability by creating DKIM and SPF entries in your domain’s DNS settings.

When our Email Marketing module sends out your marketing emails, it sends them through a third party bulk emailing system called SendGrid. We use SendGrid both to deliver emails and to track opens, click-throughs, bounces and unsubscribes.

Without the extra DNS entries some email clients, notably Gmail and Outlook, will show the From field in the emails as “Sent by Really Simple Systems on behalf of” and then your email address. If you are only sending a few emails out every month, this isn’t a huge problem.

However, if you are sending 10k or more emails out every month then it is worth taking the time to add DKIM and SPF entries to your domain’s DNS settings. These settings tell the recipients’ email servers and spam filters that the sending mail server is authorised to send emails on your behalf, and isn’t a spammer.

To make these setting you will need access to the DNS server that maintains your domain. This is normally done by your IT department or whoever manages your website. If this isn’t you, forward this page to the correct person.

Creating the DNS Entries for your DKIM and SPF Records

The entries for your DKIM and SPF settings are maintained automatically by SendGrid. To enable SendGrid to do this you need to create three CNAME records on your DNS settings.

Please contact our Customer Support Team who will create the values for CNAME records and send them to you.
