Create Temporary Email with Custom Domain: A Comprehensive Guide

Step 2: Set up email hosting with catch-all

Most domain registrars or email providers offer catch-all (accepts *@yourdomain.com).

Step 3: Set Up DNS Records

Creating a temporary email with a custom domain offers the perfect balance of anonymity and authority. Whether you use a simple Catch-All via Cloudflare or a dedicated alias manager like SimpleLogin, you’ll finally have the power to "kill" an email address the moment it becomes a nuisance.

Technical Considerations

• Email receiving – Custom MX records must point to your service (or use catch-all + API filtering)
• Storage – Use Redis + TTL for fast expiry, or S3 with Lambda for inbound parsing
• Outbound not required – This feature is receive-only (sending would ruin temp nature and require SPF/DKIM)

Email Address Generation: Upon selecting a domain, the system generates a random, unique local part for the email address. Users can also have the option to customize the local part to some extent (within certain limits) for better personalization.
