email questions

November 10, 2024 questions on email for a Comcast account:

1.) If I switch to T-fiber for internet, will I lose my comcast email address that I have had for close to 30 years?

2.) Also, why are there so many broken links/inability to see images on messages sent to me?

3.) Why is there so so so much spam recently with the email address being ones like this: <user+ 4 digit number--@comcast.net> and other ones that say "user + a number@comcast.net?  What can be done about that?

4.)  Why can I no longer embed an image right in the body of an email like we used to be able to do?

Thanks for your response.
