The one-year license period for Aid4Mail does not start from the purchase date, but from the date the license is first activated.
So if you have purchased multiple licenses, they can all have different expiry dates, depending on the date each license was activated.
In regards to renewing Aid4Mail, this means that it doesn't matter if you renew your subscription early, as long as you don't activate the license until you need it.
As of the 1st of November 2016, you will need to renew your license prior to expiry to benefit from the 50% renewal discount. If you renew after your license expires, you will instead benefit from a 25% discount.
If you experience any issues, don't hesitate to contact us.
