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.
