Microsoft Tightens the Rules for Business Email
Microsoft has recently published a major announcement introducing new email authentication requirements for businesses sending high volumes of email—especially those using Outlook.com, Hotmail, Live.com, and other Microsoft consumer services.
If your emails aren’t properly authenticated using industry standards like SPF, DKIM, and DMARC, Microsoft may block them, or route them straight to the recipient’s spam folder.
These new rules are part of a broader push to:
- Reduce email spoofing and phishing
- Enhance the trustworthiness of inboxes, and
- Protect users from malicious actors
Microsoft is urging all high-volume senders (sending more than 5,000 emails per day) to ensure compliance—and fast.
What is DMARC, and Why Does It Matter?
DMARC (Domain-based Message Authentication, Reporting and Conformance) is a protocol that verifies whether an email is genuinely sent from your domain—or whether a cybercriminal is pretending to be you.
Without DMARC in place, attackers can impersonate your email address to:
- Phish your customers or staff
- Trick users into clicking fake invoices or login links
- Damage your reputation and email deliverability
Sendmarc makes DMARC implementation simple, fast, and effective—no in-house expertise required.
