Authenticating Email Blaster Emails with SPF and DKIM

Why are my Email Blaster emails going to Spam?

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

How to stop Email Blaster emails going to Junk.

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

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

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

How to stop Email Blaster Failing DMARC

To ensure that your Email Blaster campaigns pass DMARC and get delivered to your prospects, it is important to ensure that DKIM and SPF passes authentication for your domain. A common mistake is to sign an email with Email Blaster's own DKIM keys. However, in order for Email Blaster's email to pass authentication for your own domain, it is necessary to use your own DKIM keys as per Email Blaster's own guide. If you wish to verify the above, paste the message headers for a failed Email Blaster message into our Email Blaster email testing tool. Furthermore, you should also follow the instructions on how to set up SPF authentication for Email Blaster.
