Alias - Send from your own domain without leaving Gmail

Alias adds a separate Send via button to Gmail. Compose normally and send from your verified custom domain through your own Resend account. Replies follow your existing email forwarding, including Cloudflare Email Routing. Keep your inbox and existing MX records. Requires a domain and Resend API key; provider limits apply. Hosted sending is not available yet.

I use Cloudflare Email Routing to forward help@audiofetcher.com to Gmail. Receiving worked fine, but sending from that address needed a separate setup. So I built Alias. It adds a Send via button inside Gmail and sends through your connected Resend account. Replies still come back through your existing forwarding setup, without moving your inbox. I have tested real sends, attachments and replies. You need your own domain verified in Resend and a sending API key. The extension is free to install; your domain and provider limits or charges still apply. Direct Cloudflare sending is a limited preview, and Hosted is not available while AWS production approval remains pending. I would love feedback on the setup: where do you get stuck, and what would make it clearer?
