What steps should I take when changing my domain name for email marketing?

Summary

Changing your domain name for email marketing requires a multi-faceted approach to maintain deliverability and protect your sender reputation. Experts recommend buying the new domain in advance but not immediately using it, allowing it to age. Warming up the new domain is crucial, involving a gradual increase in email volume sent to highly engaged users first. Running both the old and new domains concurrently while slowly shifting the volume helps minimize disruption. Informing subscribers about the change and updating email authentication records (SPF, DKIM, DMARC) are essential. Monitoring sender reputation, blocklists, and deliverability metrics using tools like Google Postmaster Tools is vital. Segmenting your audience and implementing a planned sunsetting strategy for the old domain, including continued monitoring and MX records for bounces, are also recommended. Consider using a subdomain to isolate email traffic. Finally, it's important to recognize new domains have heavily reduced email capacity by ISPs for up to 6 months.

Key findings

  • Domain Aging & Resting: Purchase the new domain ahead of time, allow it to age, and rest it for about 30 days before use.
  • Domain Warming: Gradually warm up the new domain by sending low volumes of emails initially to engaged users.
  • Subscriber Notification: Inform subscribers about the upcoming domain change and ask them to update their contact lists.
  • Concurrent Operation: Run both old and new domains simultaneously, slowly transitioning email volume.
  • Technical Configuration: Update SPF, DKIM, and DMARC records for the new domain.
  • Performance Monitoring: Actively monitor sender reputation, blocklists, and deliverability metrics.
  • Volume Reduction: Be aware of the heavy ISP volume limits on new domains for the first 6 months.

Key considerations

  • Gradual Transition: Implement a well-planned, phased approach to minimize disruptions and maintain deliverability.
  • Reputation Management: Prioritize building and maintaining a positive sender reputation on the new domain.
  • Audience Segmentation: Start by sending to your most engaged audience segments to establish a good reputation.
  • Old Domain Management: Develop and execute a sunsetting strategy for the old domain, continue to monitor old domain metrics and consider to auto-reply.
  • Subdomain Strategy: Evaluate if using a subdomain could help isolate email traffic and protect your main domain's reputation.
  • ISP limitations: Plan email sends within email capabilties for new domains for 6 months.

What the experts say

5 expert opinions

When changing your domain name for email marketing, experts recommend a phased approach focused on warming the new domain and carefully managing the transition. Crucial steps include purchasing the new domain well in advance but avoiding immediate email use, allowing it to age. Once ready, domain warming is essential, similar to IP warming, and involves gradually increasing email volume. Running both the old and new domains concurrently, while slowly shifting volume, minimizes disruption and informs subscribers of the change. It's also advised to 'rest' the domain for about a month before active use. Post-transition, implementing a sunsetting strategy for the old domain, monitoring for bounces, and updating contact information are important. Continuous blocklist monitoring is vital for maintaining deliverability throughout the process.

Key opinions

  • Domain Aging: Purchase the new domain in advance and allow it to age before sending email.
  • Domain Warming: Warm up the new domain gradually, increasing email volume over time.
  • Concurrent Operation: Run both old and new domains simultaneously, slowly migrating email volume.
  • Sunsetting Strategy: Implement a plan to eventually sunset the old domain while maintaining monitoring and communication.
  • Blocklist Monitoring: Continuously monitor blocklists to ensure deliverability of the new domain.
  • Rest Period: Let the new domain rest for a period (e.g., 30 days) before starting to send emails.

Key considerations

  • Phased Approach: Implement a gradual and well-planned transition to minimize disruption.
  • Reputation: Take careful steps for both IP and Domain reputation.
  • Subscriber Awareness: Keep subscribers informed about the domain change.
  • Continuous Monitoring: Regularly check blocklists.
  • Old Domain Management: Plan to Sunset the Old Domain.

What the documentation says

5 technical articles

When changing your domain name for email marketing, technical documentation emphasizes several key steps. Updating DNS records, specifically SPF, DKIM, and DMARC, is critical for proper email authentication. Implementing a DMARC policy, starting with 'p=none' for monitoring, helps protect against spoofing. Migrating email accounts involves creating new user accounts, transferring data, and updating client settings, requiring careful planning. Continuous monitoring of deliverability metrics (open rates, bounce rates, complaints) and blocklists is also crucial for identifying and addressing any issues promptly.

Key findings

  • SPF Record Update: Update SPF records to include the new domain and all authorized sending sources.
  • DKIM Implementation: Generate a new DKIM key pair, add the public key to DNS, and configure email servers to sign messages.
  • DMARC Policy: Implement a DMARC policy, starting with 'p=none' for monitoring and gradually increasing stringency.
  • Email Account Migration: Migrate email accounts by creating new user accounts and transferring data.
  • Performance Monitoring: Continuously monitor deliverability metrics and blocklists.

Key considerations

  • DNS Configuration: Pay careful attention to updating and testing DNS settings for SPF, DKIM, and DMARC.
  • DMARC Enforcement: Incrementally increase DMARC policy to ensure legitimate emails are properly authenticated before enforcing stricter policies.
  • Planned Migration: Plan the email account migration carefully to minimize disruption for users.
  • Constant Vigilance: Requires ongoing monitoring of email metrics.
