Free Unlimited Full-Featured Domain Email Solution - Cloudflare Email Routing Catch-all for Receiving + Zoho for Sending

Technology ~1166 words · 3 min read - views

Free domain email or business email services are becoming rare. The remaining few have limited features with precision pricing - you need to pay to solve any pain points. I’ve been using Cloudflare email routing with Catch-all address configuration to enable wildcard email functionality, allowing any email address (even non-existent ones) to receive and forward mail to a specified inbox.

However, this solution only solves the receiving problem - sending isn’t possible. Although you can use Google or Outlook as a relay, the actual effect is the same as common spam with forged addresses - most emails will go to spam or be rejected.

So I came up with an unconventional solution that enables both receiving and sending freely. By setting MX priority, Cloudflare receives mail with priority while Zoho only sends (doesn’t receive), improving send success rate. In my testing, I achieved 100% successful delivery.
