How to resolve email deliverability issues to Outlook spam folder after subdomain change?

After a subdomain change, resolving email deliverability issues to Outlook's spam folder requires a multifaceted approach. A key initial step is to proactively contact Microsoft's postmaster support to request mitigation, clearly articulating the change. Simultaneously, it's critical to verify the scope of the problem by analyzing engagement metrics like clicks and image loads, and confirming direct reports from users landing in spam. Building a positive sender reputation from scratch involves warming up the new subdomain by gradually sending emails to the most engaged users first. Maintaining a clean email list by monitoring and reducing bounce rates is essential. The IP address's reputation must be assessed, considering a dedicated IP if on a shared one. Email authentication, particularly SPF, DKIM, and DMARC, must be correctly configured for the new subdomain, and tools like Google Postmaster Tools should be utilized to diagnose deliverability issues by tracking reputation and spam complaints. Content should be audited for spam triggers like excessive punctuation or 'spammy' keywords. Setting up feedback loops helps manage spam complaints, and segmenting email lists can improve engagement. Maintaining a consistent sender name and 'from' address builds trust, and analyzing email headers of messages that land in spam can reveal authentication or content-related triggers. Before sending, previewing content with tools like Mail-Tester offers a chance to identify potential spam triggers. Following industry best practices, and leveraging suppression lists to avoid sending to uninterested recipients further improve deliverability.

After a subdomain change, email deliverability issues to Outlook spam folders often arise due to reputation and authentication problems. Warming up the new subdomain gradually with engaged users, monitoring bounce rates, and ensuring a good IP reputation are crucial. Content analysis for spam triggers, setting up feedback loops, and segmenting email lists enhance deliverability. Maintaining consistent sender information, analyzing email headers when spam occurs, and previewing content with tools like Mail-Tester aid in identifying and resolving issues.

Resolving email deliverability issues to Outlook after a subdomain change involves several key actions. Opening a support ticket with Microsoft's postmaster support to request mitigation for the new subdomain is crucial, requiring clear and concise communication. Verifying deliverability problems by checking for recipient engagement (clicks, image loads) and confirming spam reports is also essential. Prioritizing sending to engaged subscribers initially helps maintain a positive sending reputation. Finally, ensure proper email authentication by verifying SPF, DKIM, and DMARC records for the new subdomain to avoid authentication failures.

Resolving email deliverability issues in Outlook after a subdomain change hinges on several technical factors. Maintaining a good sender reputation is paramount, which can be monitored using Microsoft's SNDS and JMRP. Ensuring correct setup of email authentication protocols (SPF, DKIM, DMARC) is critical. Google Postmaster Tools aids in diagnosing issues by tracking reputation, spam rates, and feedback loops. Utilizing suppression lists to avoid sending to unsubscribed or problematic recipients is also essential. Adhering to industry best practices, such as those outlined by M3AAWG, provides a solid foundation for outbound email.
