So, I like to check my email on my computer using Apple Mail, I also like to check it on my iPhone, and I also like to check it on the Gmail website when I'm not home. The thing is, when I open an email in say Apple Mail, it isn't shown as opened on my iPhone. This makes it hard for me to see if I have new emails, or just emails that I need to read again. I'm really just getting annoyed seeing all the stuff twice. Is there a way to link all the clients together, so when I open it on one, it will show universally that its been opened. There was a point when I had like 34 unopened messages on my phone, but I had deleted or read them all on my computer previously. Thanks!
