DKIM, SPF and DMARC are a set of email authentication records used by the email industry to help email recipients identify the authenticity of an email and its origin. When you define these records for your custom domain, you can decrease the likelihood of your email being marked as spam or rejected.

PLEASE NOTE: If you use HoneyBook’s default email sending service, no need to be concerned about DKIM, SPF, or DMARC because HoneyBook handles this for you.

If you integrate your email with HoneyBook and that email uses a custom domain (e.g. @yourbusinessname.com) and not a generic name (e.g. @gmail.com), you may need to define DKIM, SPF and DMARC records with your custom domain provider.

You can check if these records are properly defined for your custom domain directly in HoneyBook.

DomainKeys Identified Mail (DKIM)

This security protocol signs every email sent from your domain with a public key, so that the servers of those receiving your email can check the key to validate that the email actually came from you.

DKIM records are TXT records. A DKIM TXT record includes both a TXT record name and record value that contains the DKIM public key. The key can either be 1024-bit or 2048-bit in length. Both the record name and record value should be generated by your email provider and then added to the Domain Name System (DNS) settings of your domain provider.

Here is an example* of a DKIM record name and record value:

Name: mail._domainkey.example.com
Value: v=DKIM1; p=36E374F292D293747382EEEEBF3834720374CKAHEH23JLUHRWORHQ23EERS9FHK

*Do not use the above DKIM record for your domain—this is just an example.

PLEASE NOTE: Defining this record is done entirely outside of HoneyBook. HoneyBook is not able to complete this process for you, and you will not need to enter any information in your HoneyBook account.

Sender Policy Framework (SPF)

This security protocol defines a list of IP addresses that are permitted to send emails from your domain name.

SPF records are TXT records (text only) that store information about your domain. SPF records will look different depending on how you configure them to behave.

Here is an example* of what an SPF record can look like:

v=spf1 include:_spf.website.com ~all

*Do not use the above SPF record for your domain—this is just an example.

Domain-based Message Authentication, Reporting, & Conformance (DMARC)

This security protocol builds upon SPF and DKIM by providing a way for email recipients to determine if an email message is legitimate, fraudulent or suspicious.

DMARC is a TXT record that incorporates both DKIM and SPF. Prior to setting up DMARC, you will need to make sure DKIM and SPF are set up for your domain.

Here is an example* of a DMARC policy record:

v=DMARC1; p=reject; rua=mailto:[email protected]

*Do not use the above DMARC record for your domain—this is just an example.
