I deleted lots of emails but I can still see them in my email app.
Clean Email works directly with your email server and all actions started in Clean Email reflect directly in your email account. However, that may or may not also reflect on your local devices, being a phone or a computer. It all depends what kind of app/software (email client) you are using to read your email and how it is set up.
The email clients can be set up to access the email server in 2 ways: using POP3 protocol and using IMAP protocol. Both protocols serve the same purpose but they are working in different ways. In a few words, POP3 is a protocol which downloads emails from a server locally on the device (phone/laptop) while IMAP shows emails directly from the server.
If your email app/software was set to use the POP3 protocol to access your email, that is actually downloading messages locally in the phone or computer where our service can not get. If your email app/software was set to use IMAP protocol, that is always showing the emails as they are on the server, so any changes made by Clean Email will reflect on your device as well.
Putting that together we can conclude this: If you will set up your local apps/software to use IMAP to access your email you will always see the same emails from all your devices and not have emails copies downloaded locally. All changes Clean Email will make on your email account will reflect in all your devices. If you use POP3, emails from the server will be downloaded locally on your device, sometimes even before Clean Email has a chance to clean it from the server. Since Clean Email can not access your devices, it can not clean those emails.
