If your main use case is to keep using Gmail with a custom domain, then it’s still possible to achieve it using our service - improvmx.com. We’ve prepared a guide that explains how to migrate step-by-step: https://improvmx.com/guides/gsuite-legacy-free-edition-alter...
Achieving the same functionality is possible on our free plan, and you can still use Gmail’s free SMTP method (https://improvmx.com/guides/send-emails-using-gmail/) to send emails from your alias, so no need to upgrade to anything.
One main caveat: since it’s not possible to downgrade a G Suite account to a « free » one, you would need to create a new Google account for each of your users. That would mean that you’d lose all previously bought subscriptions or apps bought on Google Play with your account.
