Hmmm. I think you just need some help filling in boxes with the right info.
Your Suddenlink account is a POP mail account. You will need to fill in your username and password, and for incoming server, you fill in “pop.suddenlink.net” and for outgoing mail you fill in “smtp.suddenlink.net” (minus the quotation marks).
I think that’s all you need to connect to your suddenlink mail.
TY
I’ll give that a try.
