Granicus SPF and DKIM configuration: Step By Step Guideline

This instructional article will demonstrate the Granicus configuration process of Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM) Signatures to ensure Granicus passes the DMARC alignment check and eliminates spam from your domain, and increases security.

The SPF record identifies the mail servers and domains that are allowed to send email on behalf of your domain. The DKIM record, on the other hand, is a specially formatted DNS TXT record that stores the public key the receiving mail server will use to verify a message’s signature. These email authentication methods will be used to prove to ISPs and mail services that senders are truly authorized to send email from a particular domain and are a way of verifying your email-sending server is sending emails through your domain.

Important Note: Granicus is a subdomain-capable source, which means you need to set up a subdomain and use that subdomain to send your emails, instead of the top-level domain. For example, the email address should end with @subdomain.domain.com, rather than @domain.com.

The process of configuring SPF

In order to authenticate Granicus on SPF, please follow these steps:

1. Login and head to your DNS Zone provider
2. Create a new TXT record
3. Input the DNS name as <Subdomain>
4. Input the DNS value as v=spf1 include:public.govdelivery.com ~all
5. Save the record
6. Wait up to 72 hours to allow your DNS to process the changes

The screenshot below will show you an example of the SPF record. We’ll be using CloudFlare for this example.

Important Note: Each domain must have only one SPF TXT Record. If you have multiple SPF Records, SPF will return a PermError. 

If you are using multiple IPs, ESPs, Third-Party services for your various email strategies, you should include them in a single SPF Record.
E.g v=spf1 ip4:18.57.156.221 include:public.govdelivery.com include:thirdpartyservice.com ~all

The process of configuring DKIM

In order to authenticate Granicus on DKIM, please contact their support team to generate a DKIM key for you and activate it on your domain.

Congratulations, you now successfully authenticated your outgoing mail stream from Granicus with SPF and DKIM.
