Today is day 2 of the Evernote Conference (EC4), bringing speakers like Tim Ferris, LinkedIn cofounder Reid Hoffman, and Founder Institute’s Adeo Ressi to San Francisco to talk about how they use Evernote.

Evernote-based startups are also launching at the conference, including email marketing tool Mastodon. Mastodon lets you create and send an email newsletter right inside an Evernote note. Here’s how it works:

First, you import your contacts and create a list:

Then, give the list a tag:

Head over to your notes, and create a campaign. This is just like creating any other note in Evernote, with a text editor with drag-and-drop functionality. You can add pictures and videos and customize the look without knowing any HTML or CSS. You can also share the campaign with collaborators on your team. When you’re ready to send, simply add the list’s tag to the note (“customers,” in the example above) – as well as the tag “send” – and it’ll be sent out to that list.

Afterward, see your open rates:

Mastodon is free, with paid versions costing $10-35 a month. Today it’s launching in private beta, so you can sign up on their website to get access. Mastodon was founded by Lindsey C. Holmes, an Evernote small business ambassador, certified Evernote business consultant, and a Tech Cocktail contributor.
