Why doesn't Cox support IMAP email service so users don't need to re-read their emails on each client device?

I'll certainly pass your request along to our messaging team.  In the meanwhile most portable devices now leave copies on the server when using POP access.  Desktop email clients can also be configured to do this although it may not be the default.

Thanks Chris but I already use this option. This requires me to re-read/review or manage hundreds of emails on various client devices rather than deleting them once across devices.

Just to clarify, after talking for an hour with a residential customer service rep via chat, I was told that IMAP services are not an option for residential customers and I would need to switch to a business account to have IMAP email services. After inquiring with a business chat represented, I was repeated upsold on the $99/month package when a lesser basic internet package (Residential Home Professional) was available for $74/month.  However, one more glitch occurred.  According to the business account rep, my residential address was shown as a commercial property. Go figure!

I'm not surprised. You have to think about how many customers Cox has on the residential side. Not making an excuse just that IMAP is CPU intensive and would mean everyone is storing mail on their server. This is why I use a hosting company and have my own domain name. So much easier. I have a choice if I want to setup POP3/IMAP/Webmail or all three at once. IMAP is the way to go.

Remember, if you switch to Cox Business, you won't be able to keep your @cox.net email address. They will give you another email that will have a specific domain for your area. 

Thanks Trikein. That's some good advice to consider. Short of creating a business account, I'm thinking of just adding more mail services to one of my domain names as mentioned by olsj87.
