Hello @nshansundaram@gmail.com @MrFlexible,

Thank you for your patience.

I have checked your accounts and our records show you are already using Nitro Pro 13.

In line with this, please ignore the upgrade email offer as it is intended for Nitro Pro 12 and older versions users.

Our sincere apologies for this confusion and Happy New Year!
