Guard your Inbox with this easy-to-use Software

Junk e-mail is a problem that never seems to go away. Greenlight Guardian is a powerful solution that runs on a simple idea—before email can be sent to your inbox, the sender must get the ‘Green Light’.

Each time an e-mail is sent to your address, Greenlight Guardian will check for the sender’s address. Only those addresses on the White List get the Green Light, so e-mail from unrecognized senders never reaches your inbox!

Simply download and install using Ascentive’s Easy-Install™ and follow the simple step-by-step instructions to protect your inbox. Try Greenlight Guardian today backed by a 30 day money-back guarantee and one full year of technical support!

How it works:

White List vs. Black List
Greenlight Guardian will instantly import contacts from your address book. Once an address is added to the White List, all emails from that address will get the Green Light and will be sent directly to your inbox. Restricted e-mail addresses are added to the Black List, and any emails from these addresses are sent directly to your Junk Folder so you never receive spam again.

Get the Green Light
If an address is not found on the White List or Black List, Greenlight Guardian automatically delivers a request to the sender to verify that they are a legitimate e-mail author instead of a spam-bot. The sender can verify their email in a single click, and will be added instantly to the White List. All future emails from that contact will get the Green Light and go directly to your inbox.

Clean Inbox Guaranteed
This proven method will keep your inbox spotless--Guaranteed! If you are not completely satisfied with Greenlight Guardian, Ascentive Software will give you a full refund in the first 30 days.
