Here are some strategies to avoid mismatched domains:
Consistent Branding: Ensure that the email domain and the domains of any links are consistent with your brand. This not only helps in deliverability but also in reinforcing your brand. Use Subdomains: If you need to link to different parts of your business, consider using subdomains (e.g., offers.example.com) to keep the domain alignment intact. Authenticate Your Domain: Implement email authentication protocols like DKIM, SPF, and DMARC to enhance your sender reputation.
