Well, that's true, but also not. Switching email, for example, is about as easy as getting a Gmail account in the first place - several services have "import from Gmail" as a default offering.
It just *feels* like it's a huge deal - like you're going to mess something up. You almost certainly won't but *you don't have to delete your Gmail to switch*! Leave it on for a bit while using your new email, until the dread feeling goes away.
People need to be told this, again & again.
