Authenticating Hostinger Emails with DKIM

Why are my Hostinger emails going to Spam?

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

How to stop Hostinger emails going to Junk.

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

How to remove ‘via hostinger.com’ or ‘on behalf of hostinger.com’

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

How to stop Hostinger Failing DMARC

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