sweetmail is an email app. The relationship between messages can be displayed in an easy-to-understand manner. You can switch between multi-stage and single-stage so that the steps are not too deep and difficult to see. There is also a special window where you can list all messages. When you write a message, the first sentence is created from a blueprint. You can create any number of blueprints, and you can set a default blueprints for each folder. You can also automatically sort messages using rules. Data can be transferred from the old version of SweetMail, so you can read System7 era messages. There is a limit to the number of accounts, blueprints and rules you can make. If you purchase a item in the app, you will be able to make it without any restrictions. Please note. We hope this app help you a little
