How do I upgrade to more than just 2 accounts

NULL

By buying the Pro license: http://www.emclient.com/purchase?lang=en

how many email addresses/accounts can use with the Pro?

sorry, how many accounts do you get with the Pro and do you have to renew every year for a price?

Hi, I’m d’ont know if there is a limit of accounts in the pro-version. I have actually 9 accounts and 321 contacts.

There is no limitation on the Pro. You don’t need to renew the license every year, and it worth 1 upgrade within a year. However after 1 year, and if there’s a newer version you would like to use, you need to renew the license for the newer version: http://www.emclient.com/renew-license

Alternatively you can pay a extra once-off for the lifetime upgrade: https://sites.fastspring.com/emclient…
