If you want to create your own email address with a specific domain name something.ch then unless that domain name already exists and you happen to be able to piggy-back off that website (very unlikely) then you have to create it yourself which means registering the domain name.  Its not a difficult process at all - for swiss website look at

www.switch.ch

https://www.switchplus.ch/?lang=en

other countries have different domain name registrars which can be much cheaper (eg you can get a .co.uk from a UK registrar for next to nothing) but if you want a .ch then switch is dominant

It is possible to register a domain name without having hosting. You just need to be sure that the registar offers an email service. Or, you need to find a "web host" with a plan that offers email only.

A provider that I have used is Infomaniak

  http://www.infomaniak.ch

They are pretty good and provide many options.

I use metanet.ch

Slightly cheaper than infomaniak, and I'm perfectly happy with them

Thank you so much wise men

So Zonker, who would provide only emails without hosting. I can get the domaine name at switch.ch, for just 15frs annually, BUT not sure if it includes email ids easily configurated from thereon. 

Checked metanet.ch & its in german only. Any other eng/fr options would be more helpful. Thanks 

How about this?

I just purchased a domain for CHF 12 a year from informaniak which includes one email address. It is dead simple to set up and use.

If you want several addresses and other features, I'd go for Zonker's suggestion. I nearly did but realised that I don't relly need it.

On thing with infomaniak which nearly put me off using them is the fact that you have to register to the site first to see full details and pricing and to order.

Thanks again buddies. Any others needing some IT advise, why not profit from this post.

Enjoy your easter break.

I have this though go daddy but it's .com not a .ch. I don't know if you can migrate your .ch to them. Have look at their website. 

Thanks zonker. You are the best  Mia. Not so sure about godaddy. Have to check.

Kabir,

So, what did you end up doing? Still need help? This is something that can be done in about 10-30 minutes. If you need help, let me know.

I use gmail on my own domains, it used to be free and now it's 4€/month per user (or 40€/year) but you get all the advantages of gmail, plus the freedom to keep your domain and switch to another email provider if you change your mind later.
