Emailchemy says my registration key is not valid

You are here:

This message means your license key is either entered incorrectly or that your key is not valid for the version of Emailchemy you are trying to install.

If you are certain that your key is valid, for example if you just purchased it, please try entering the key again. The name and key must be entered exactly as they appear in the email which your key was delivered. Try copy and paste directly from this email. Letter capitalization matters.

If your key is over a year old, it may not work with the latest version of Emailchemy. If this is the case, you can continue to use the previous version of Emailchemy, or you can contact our helpdesk support ( to request a renewal discount to purchase a new key that will work with the newest Emailchemy.
