in my country we don't use text messages or emails to contact but whatsapp (so no emails) I have 7 gmail accounts, 1 main one, a secondary one that I manage for a family member and another older one that I have just for nostalgia, I use the others for spam. I only use Apple apps and they work great for me.I could never use proton mail as the main one, the apple services I use are: reminders, apple maps, imessage, drive, and other apple apps, they work. owned by google I only use youtube and gmail
