Authenticating Greenhouse Emails with DKIM

Why are my Greenhouse emails going to Spam?

If you have a problem with Greenhouse emails going to spam, that is, going to the junk folder of your recipients, then it is very likely an issue with your email authentication. Emails failing authentication, be they failing SPF, failing DKIM, or failing DMARC is common, as SPF, DKIM, and DMARC are often not properly implemented by domain administrators. Often, the main cause of Greenhouse emails being blocked is due to the Greenhouse emails failing DMARC, which in the case of Greenhouse, is usually due to a misconfiguration of DKIM.

How to stop Greenhouse emails going to Junk.

The first step to preventing Greenhouse email going to spam is to retrieve a failed message and access its header information. This will allow you to quickly diagnose whether any authentication issues such as DKIM or DMARC are flagging your email as spam, instructing the recipient sender to move it to junk. Simply paste the email headers into our free Stellastra Deliverability Tool, which you can use freely with no log in required. Our deliverability tool should allow you to avoid Greenhouse emails from going to spam, or at least rule out authentication as the issue.

How to remove ‘via greenhouse.io’ or ‘on behalf of greenhouse.io’

Another example of where a Greenhouse DKIM misconfiguration is to blame, is if your recipients report seeing the message as ‘via greenhouse.io’ or ‘on behalf of greenhouse.io’ and that the emails typically end up in spam or junk. The Stellastra Email Deliverability tool above will confirm this prognosis, however, you may also wish to configure DKIM for Greenhouse by logging in to your Greenhouse account to check to see if you have followed the following article to configure your Greenhouse dkim setup to authenticate your domain.

How to stop Greenhouse Failing DMARC

To ensure that your Greenhouse campaigns pass DMARC and get delivered to your prospects, it is important to ensure that DKIM passes authentication for your domain. A common mistake is to sign an email with Greenhouse DKIM keys. However, in order for Greenhouse email to pass authentication for your own domain, it is necessary to use your own DKIM keys as per Greenhouse’s own guide. If you wish to verify the above, paste the message headers for a failed Greenhouse message into our Greenhouse email testing tool

How can I gain visibility over who is sending with my domain?

Stellastra’s email deliverability visibility tool takes reports from all modern inbox providers including Google (Gmail), Microsoft (Outlook), Mimecast, and Zoho to show who is sending email using your domain. This ensures that 1) you are monitoring your outbound emails to diagnose why emails are going to spam, and 2) that you take steps to lock down your domain, become secure, and comply with Google and Yahoo’s 2024 bulk email sending policies.

How can I ensure I am compliant with Yahoo and Google’s 2024 Email Sending DMARC Guidelines?

Our email deliverability visibility tool will indicate whether you are compliant with Google and Yahoo’s February 2024 email guidelines for bulk senders. Google sends us reports alongside all modern email inbox providers.
