Authenticating Exact Online Emails with DKIM

Why are my Exact Online emails going to Spam?

If you have a problem with Exact Online 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 Exact Online emails being blocked is due to the Exact Online emails failing DMARC, which in the case of Exact Online, is usually due to a misconfiguration of DKIM.

How to stop Exact Online emails going to Junk.

The first step to preventing Exact Online 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 Exact Online emails from going to spam, or at least rule out authentication as the issue.

How to remove 'via exactonline.com' or 'on behalf of exactonline.com'

Another example of where a Exact Online DKIM misconfiguration is to blame, is if your recipients report seeing the message as 'via exactonline.com' or 'on behalf of exactonline.com' 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 Exact Online by logging in to your Exact Online account to check to see if you have followed the following article to configure your Exact Online dkim setup to authenticate your domain.

How to stop Exact Online Failing DMARC

To ensure that your Exact Online 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 Exact Online DKIM keys. However, in order for Exact Online email to pass authentication for your own domain, it is necessary to use your own DKIM keys as per Exact Online's own guide. If you wish to verify the above, paste the message headers for a failed Exact Online message into our Exact Online 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.

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.
