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.

What the experts say
5Expert 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.
