Get email from local activation

I see the lexactivator library has a few methods to get data associated with the product key: GetExtraActivationData, GetCustomLicenseField, GetProductKey and GetDaysLeftToExpiration. In my case I’d like to get the email associated with the product key. Now I have to use the web API to get this email which is a lot slower than using the lexactivator library. Is it possible to get the email and also the product key id with this local library?

You can’t get the product key id and email directly using the LexActivator API. If it’s a matter of speed due to network request, you can store them in custom fields.
