Each pack contains a card with a key inside, for example here is a demo:

■ electronic pdf file: (Synology only supplies to distributor or reseller)

Each license includes a unique 20-digit key (format: xxxxx-xxxxx-xxxxx-xxxxx). Licenses can be combined to add multiple email accounts based on your requirements.
For example, to connect 30 additional accounts, add one 20-accounts licenses and two 5-accounts licenses.

MailPlus License key is permanently valid with lifetime update. You could also migrate them to another Synology NAS.

Important Notes:

• Only active email accounts need licenses. You can re-use licenses from deactivated accounts.
• Email aliases DO NOT need separate licenses.
