I tried using Forward Email, a service that forwards emails sent to custom domain email addresses for free, so I’ll introduce the setup methods for initial registration, email receiving, email sending, etc.

Background: Forward Email as Migration Destination Following End of Free G Suite

Since 無償版 G Suite が終了する (the free version of G Suite is ending), I decided to use Forward Email as the migration destination for handling sending and receiving of custom domain email addresses.

Forward Email Pricing Plan Comparison

Forward Email の料金プランはこちらのページ (Forward Email’s pricing plans can be found on this page).

With the free plan, you need to set the forwarding email address in a TXT record, making it visible to everyone. However, with the $3/month plan, you don’t need to set the forwarding email address information in the TXT record, allowing you to hide it from third parties.

1. Open https://forwardemail.net/ja
2. [Custom Domain]: your-domain.example.com
3. [Existing Email]: [email protected]
4. Click [Get Started] button

That’s all from the Gemba, where I set up email sending and receiving for custom domain email addresses with Forward Email.
