Implementing NetSuite DMARC-compliant Email

This article is relevant if you are using NetSuite and you are having trouble with bounced email messages when you send them from NetSuite.


NetSuite offers to major ways it sends emails on your behalf:

  1. Transactional: as you send communications via your day to day business operations, NetSuite can send email and make it appear as if they are coming from you.
  2. Campaign: if you elect to use NetSuite’s bulk email capacities, you can produce targeted email messages.

With frameworks now in place to help with some of the spam management concerns, it is important you setup your Domain Name Server  (DNS) according to the latest guidelines.  Some of the setup can be a bit confusing if you do not do this all the time.

Key DKIM and SPF Setup Elements

NetSuite offers a guide in the Help document for how to setup the DomainKeys Identified Email (DKIM) using the Sender Policy Framework (SPF).  The NetSuite Help manual should serve as your guide.  Search on this topic to get oriented.  However, it may be a bit confusing what syntax is required in your DNS provider.   The authority for the SPF record setup  is located here.

We use DNSMadeEasy for our DNS services.  They offer a way to see a standard DNS Zone file which many other DNS servers accept.  I am providing ours below so you can see the syntax.  I am also providing a screenshot to help you see an example.

Sample NetSuite DNS Entry

; Current zone definition
;--------------------------------------------- 1800 IN A 1800 IN MX 20 1800 IN MX 10 1800 IN MX 20 1800 IN SPF "v=spf1 -all" 1800 IN SPF "v=spf1 ~all"
* 1800 IN A 1800 IN CNAME 1800 IN TXT "v=DKIM1;k=rsa;p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDNa/uy1ARFkT1mR5ZZZZZldrHQZeV67SSyJzNqabtzunD6qIlbjOOQkqDawTMDhwxrVzJ7m7sXB80QOySHHrOD4pnvqnzjtrGdD/ecx+L0J/CJJDikIQgVPMUUjajQwmvfBu7bk0flu1LBS0qL4cdH68PxZyLr5yTc15nzkcQwIDAQAB" 1800 IN CNAME
