Is it possible for emails to be lost when emailing to another country?
Every time I try to email one of my friends from a different country, I don’t think it goes through because they never reply to my emails and when they email me they say nothing about any of the previous emails I sent them, like they never got them. If this is possible, which email servers are good to use when emailing to a different country and how can I prevent my emails from being lost again?? thanks!
