Create Email Newsletters on the fly with Goodbits
Email newsletters that contain a curated collection of links are popular at the moment. Goodbits is a web app designed to simplify the process of putting together your own curated newsletter.
After installing the browser plugin, you simply click a button when you come across a website you want to include in your newsletter. When you've collected enough links, you can send the newsletter through the app which is handled by an integration with Mailchimp.
Goodbits is the easiest tool I've come across to curate a newsletter, and I use it for the weekly Taskmag email. The only downside is it requires a browser plugin - one of my pet hates.
