Keeping email address
 

I changed providers five times in the last 15 years. Never had an issue with my email address.

Well, unfortunately, you've learned the hard way that free email from your internet provider is not free. It was originally designed as a set of handcuffs to discourage customers from moving to a new ISP. Customers thinking of switching would realize "oh wait, I can't lose my email" and then continue to pay higher and higher fees to their current ISP to avoid the headache you clearly see if you change email address. This is not unlike the problem of getting a new phone number. Then, the Local Number Portability (LNP) act was established to solve that issue. Remember when you paid roaming fees when your cell phone was even 100 miles from home. Now, no one changes their phone number no matter where they go. We need the same thing with email addresses but that's harder to do with different domain names owned by different entities.

Your only option is to check with spectrum. You might be able to keep your current email address. Some ISP's (comcast) will let you keep your email even if you leave provided that you login at some frequency (once a month minimum I think). But, a quick google search seems to indicate that if you cancel Spectrum, you lose any affiliated road runner email address within 60 days.

If you are forced to get a new email, don't make the same mistake again. Choose a new neutral email domain (yahoo, hotmail, gmail, etc) or even get your own domain for email and have it hosted. MrLonzo.com is not yet registered <smile> so you could establish one or more email addresses at <anything>@mrlonzo.com.

We also dropped Spectrum but kept our roadrunner email for quote some time. Finally switched to Gmail and I believe there was a way to forward all the road runner emails to our Gmail account. It was so long ago, I don't remember.... sorry. I think if you go into your RR account, there is a tab or header that will say "forward mail to...."

I never use an isp email address because you can switch isp every year. My email address is 20+ years old but I only use this for friends. I have 167 aliases that are tied to specific sites so when I’m done with them, I delete the alias. Apple, msn, google aren’t going anywhere so I would use addresses from these companies. You can go out to each 1 of these sites and forward all emails to your main email address.
The other thing I do is setup multiple accounts for email, using the sites incoming email server, port, etc, but the outgoing server is pointing to my main email address.

If you are using an isp email that is still active even if you don’t use them, then I would forward all emails from these isp sites to your main email address

Well that's a limitation of the choices you've made, not with GMail. Gmail interface is insanely easy to use, uncomplicated, and multi-functional. I use GMail via my Firefox web browser, or my Google web browser. I rarely use the app on my phone since I can't type out long replies with my phone (I'm a keyboarder, not a texter).

You can also set auto reply to tell everyone about your new email which is a lot less work

Impressive sleuthing!!

Roadrunner email
 

I had Roadrunner over 20 years ago and switched to various other companies over the years. But my RR email address still exists and still works,
