Not sure why people use an ISP email address since you will move many times in your lifetime and will likely have to go with another ISP. There are many email accounts you can setup that don’t tie you down to any specific ISP, for example: iCloud, msn, gmail, others.
You can always setup an old email provider to forward any email to another email address. For example, I forwarded all emails from a prior Verizon email acct to my iCloud email.

It’s easy to move email providers to a new email. I have done this a few times.
Setup all email accounts under your email app on your phone/computer.
Email all you friends to tell them you have a new email address.
Modify all the businesses you deal with and modify your email address to the new address.
Since you see both email accounts on your phone/tablet/computer, over time, if you have incoming email on the old account, things you might have missed on modifying your new email address, you can change these now. Keep watching your old email accounts for at least a year or longer because you might get quarterly broker statements or maybe yearly government statements that you mig~ht have missed modifying these emails accounts to your new email address

In UK I had my broadband/email with Wanadoo some years ago.
Then it was just shut down. Nightmare changing all accounts attached to it.
Never had an email address with a broadband supplier since.
Yahoo, and Gmail work fine for me.

Yes you can keep the comcast email and there is no cost associated. Yes you can port your home phone number to Spectrum, pretty smooth process.

Yes. I have Spectrum after having Comcast and my email account with Comcast still works fine. We went with Spectrum and YouTube TV. It is much cheaper than Comcast.

Not only is it a pain to get all necessary people to know your new email address, once they type in your name, the old email will populate and they'll go for that because they forgot you changed address! At least that's what has happened to me. That's why I decided to still keep checking my hotmail account which is targeted by spam daily. GRR.

I have Comcast....triple play ...... and have no intention changing. They all suck

Any hope that Spectrum is making that offer to residents north of 466, sure hope so, will change asap.

Comcast email
 

We have had a comcast email accounts for many years. We got Spectrum when moving here,5 years ago, and still use those accounts with no problem.

Jumping between providers is a common way we save on internet service; sometimes, we bring our cell phone numbers with us. Every time the "special deal" runs out.

As a rule, we do not even talk to door knockers, we don't want to encourage them. So, we go directly online to see who is offering the lowest rate to new users this year.

And yes, the last time we had Comcast (many years ago) their customer service was extremely bad.

You keep your phone# wherever you go, but not your email address that goes through your ISP, EXCEPTION: when Verizon d/c'd its email svc and arranged for AOL to handle it xxxx@verizon.net addresses could still be used regardless of you ISP.

I also had a problem with Spectrum's router. It not only didn't run my smart home device, but I couldn't even get signal on my Lanai or garage for my cell phone.
Luckily I previously used Google wi-fi previously, so I pulled out my 3 pods and now get great connection throughout the house and yard.

You can keep your Comcast accounts, but do need to log in periodically so they don’t close them. I’ve been using & forwarding mail from them for years.

Anytime you can get away from Infinity/Comcast your ahead of the game.

As everyone has responded, yes you can keep your Comcast e-mail but I personally would change it to gmail so just in case if some time in the future anything changes you are covered.

That said if you want to keep your phone number you MUST NOT Cancel Xfinity until Spectrum Ports your number to their system or you will loose it forever. So you sign up with Spectrum, get it all installed then call Xfinity and cancel.

BTW if you can get Quantum Fiber, I would get it. $30, 200 Mbs Internet plan, no contract, no tax. If you want a landline go to Consumer Cellular and get it for $15/month. You can Port your phone number from Xfinity to Consumer Cellular not problem. Consumer Cellular will do it for you.

Just did all this for a friend in Fenney, no issues and he's paying almost $100 less per month for Internet and Phone with Quantum Fiber than with Xfinity. Xfinity and Spectrum are good companies but they rip you off with their old fashioned cable pricing plans. And don't get fooled by their $25/month internet because that's only for 2 years then you have to go back and fight with them or switch. If you switch to Quantum Fiber you are once and done.

Just called and was told Spectrum is not available just south of 466. Maybe it is just in areas south of 44?
