1. The Deliverability Crisis (SPF, DKIM, DMARC)
Legacy accounts often lack the advanced DNS configurations required by modern mail servers (Gmail, Outlook, iCloud).
The Risk
Without updated DMARC policies, your business emails are increasingly flagged as "Spam" or "Unverified."
The Impact
Lost leads, missed invoices, and a degraded sender reputation that is difficult to repair once blacklisted.
