Dear Dyn Customer,

Your Dyn account "xxx", free hostname(s) will expire in 5 days. If you
no longer need the hostname(s), simply disregard this email and expiration
will automatically occur.

Free hostnames must be updated every 30 days to remain active. Inactive
hostnames will expire and be deleted. If you wish to prevent the
hostname(s) from expiring, please visit the link below:
https://account.dyn.com/eml/expatconf/xxx/xxx

Keep your hostname(s) active without having to update every 30 days, by
purchasing a DynDNS Pro upgrade today: http://dyn.com/dns/dyndns-pro/

Thanks for choosing Dyn.
