Key Features

Customizable Templates

Gossamer Mail is completely template based: all HTML and language data is stored within our easy to edit templates. This gives you the ability to brand your content and sell it to other sites, or just create a completely different look to your site without editing code.


Make your emails stand out. Gossamer Mail's HTML editor makes it easy for you to create visually effective emails without having to know HTML coding. Change fonts, add color, bold phrases, or format your email anyway you want, all with a click of a button.

Keep Spammers Out

Prevent spammers from abusing your Gossamer Mail system. Administrators limit the number of messages each user can send per day as well as the number of addressees each message can have. Limits can also be placed on the number and size of uploads that will be permitted.
