On the server where templates are email messages? Edit them from the admin area is not convenient.

Why are they inconvenient by being in the ACP?

(Customization > Emails)

However you can find them in the MySQL database within the table `core_email_templates`

That is, all the templates are only in MySQL databases?

Yes, it's pretty common practice, the method you want was more common like 10 years ago or so.

Alternatively there are applications in the marketplace that support Mandrill if you want unlimited control over your templates.
