Hey Salesloft Community,
Microsoft is changing how they handle emails for high-volume senders. If you send over 5,000 emails daily to Outlook.com, Hotmail.com, and Live.com addresses, you need to take immediate action to ensure your emails continue to reach inboxes. Starting May 2025 Microsoft will require specific email authentication settings for your sending domain to boost inbox security.
Why This Matters for Salesloft Users:
This directly impacts whether your emails land in Outlook inboxes. Without these settings, your messages could go to spam or be rejected.
What You Need to Do (and What to Check Immediately):
- Verify SPF, DKIM, DMARC are Set Up CORRECTLY: Work with your IT team immediately to implement or double-check these email authentication methods for your sending domain, ensuring they meet the following criteria:
- SPF (Sender Policy Framework): Must Pass for the sending domain. Your domain's DNS record should accurately list authorized IP addresses/hosts.
- DKIM (DomainKeys Identified Mail): Must Pass to validate email integrity and authenticity.
- DMARC (Domain-based Message Authentication, Reporting, and Conformance): At least p=none and align with either SPF or DKIM (preferably both).
- Following Salesloft Guidelines? You Might Be Set! If you're already adhering to our Email Deliverability Best Practices guide, you may not need to take further action, but verify your SPF, DKIM, and DMARC settings against the requirements above.

- Prioritize Data Hygiene & Clear Opt-Outs: Beyond authentication, maintaining clean data and providing easily accessible unsubscribe links are crucial for deliverability and compliance with these new requirements.
