Although I have migrated my blog to this new domain, I still retain ownership of nishikori.tech. In order to better utilize this idle domain and better configure my email distribution, I still want to keep the domain email of nishikori.tech.
Although service providers like Google Workspace provide comprehensive domain email services that are convenient to use, all services require payment. In order to save expenses, I gave up using such services. And today, when many service providers block port 25 connections, it is not easy to set up a self-built email server.
Through research, I discovered Resend, which provides users with free email sending services (100 emails/day for free users, or 3000 emails/month), which perfectly meets my needs. By combining Resend with the email routing feature provided by Cloudflare, we can get a free domain email.
Preparations before starting#
-
A Resend account
-
An idle domain that uses Cloudflare's DNS service
-
An email acting as a carrier, using Gmail here
Configure Cloudflare email routing to enable receiving service#
First, open the Cloudflare console, open the target domain, and then click on the Email selection tab. Then click on Email Routing, enter the desired email address in the Custom address input box, and enter the carrier email in the Destination input box below.
Then, configure DNS resolution according to the prompts.
Following the tutorial, our domain email will have the ability to receive emails. If you don't need the sending service, you can stop here.
Configure Resend to enable sending service#
Open the Resend official website, and apply for a free API Key on the homepage or the API Keys page, and copy it for later use.
On the Settings page, select the SMTP selection tab to obtain information such as the SMTP server and port.
Log in to the carrier email and find "Add another email address" in the settings interface, and click on it.
Fill in the required information according to the prompts, and fill in the domain email address in the "Email address" field.
According to the Resend official documentation, fill in the SMTP server (smtp.resend.com), select the port (465), and fill in the username (Resend). The result is shown in the following figure.
Click "Add Account" to add the domain email to the carrier email account. Then open the inbox of the carrier email, find the authentication email, and verify it.
After the above configuration, we can select our domain email in the sending interface of the carrier email and use it to send emails.
