Implement a robust feedback loop system that aggregates data from multiple IPs and domains. This will help you quickly identify and resolve delivery issues across your entire sending infrastructure.
Finally! remember that while IP and domain rotation
Can significantly improve deliverability! it is not a panacea. It should be part of a comprehensive email marketing strategy that includes quality line database content and proper sender requirements list management. By combining these elements with a well-implemented IP and domain rotation strategy! you can maximize the deliverability of your emails and get better best claude ai alternatives in 2025 results from your email marketing campaigns.
Both Mailbox Providers (MBP) will require email senders to publish DMARC records.
In the words of two email providers! they explain the change like this:
- Yahoo : “To help our users have more confidence sender requirements in the origin of their emails! we will require senders to implement stronger email authentication using industry standards like SPF! DKIM! and DMARC.”
- Gmail : “We require those who send high volumes of email to implement strong authentication for their email in accordance with established best practices. Ultimately! this will eliminate vulnerabilities that attackers could exploit to threaten everyone who uses email.”
Note : Gmail’s definition of “high volume” is a user who sends more than 5!000 messages to a Gmail address in a single day. Yahoo didn’t provide similar numbers! though Marcel said they have roughly the same idea of what constitutes a high-volume sender.
DMARC (Domain-based Message Authentication
Reporting! and Conformance) allows senders to specify policies for handling singapore data unauthenticated messages (e.g. “p=quarantine”! “p=reject”) and provides a reporting mechanism to monitor these messages.
Senders now need to: 1) publish a DMARC record (policy can be “p=none”); 2) ensure consistency with their SPF/DKIM domains! and; 3) implement a DMARC reporting solution (recommended).
We asked our webinar audience about their current authentication practices. Only 68 percent had implemented DMARC.
This means that almost one-third do not meet the new requirements.
