Apps You Love To Use

The Rocket Science Group creates tools—web and mobile apps—that connect you with fans, keep you safe, and generally make your life easier.


  • MailChimp

    Newsletters For Business

    MailChimp helps you design email newsletters, share them on social networks, integrate with other services and track your results. And it’s how we make all our money.

  • Mandrill

    Email For Apps

    Mandrill is a transactional email service that runs on the same delivery infrastructure that powers MailChimp.

  • Tinyletter

    Newsletters for People

    TinyLetter is a simple newsletter service for people with something to say. Design a signup form, compose your letter, and reply to your readers. That's all there is to it.

  • Gather

    Gather is a mobile app for event organizers that allows them to send SMS alerts to their attendees before and during events.

  • Wavelength

    Wavelength identifies MailChimp users who share subscribers so they can learn about subscriber interests and get to know similar publishers.

  • AlterEgo

    AlterEgo is a simple, free way to add a second layer of security to consumer web applications by generating one-time codes that must be entered before users are allowed to log in.

  • Omnivore

    Omnivore is a powerful abuse-detection technology that keeps MailChimp clean by predicting bad behavior before it even happens.

  • ChimpFeedr

    ChimpFeedr is a supplement to MailChimp’s RSS-to-Email tool. It can mash several RSS feeds into one huge master feed, so you can send content from multiple sources all at once.

  • Golden Monkeys

    Golden Monkeys helps you keep track of your VIP subscribers by sending you push notifications when they open and click your newsletters.

  • Chimpadeedoo

    Chimpadeedoo lets you sign up new subscribers from your iPad. Customize the signup form, collect email addresses offline, and sync them to MailChimp when you’re back online.

  • LongRep.ly

    LongReply helps you manage customer service on Twitter. It lets you reply to tweets using more than 140 characters, and it even tracks sentiment, so you can focus on the most important tweets.

  • unFurlr

    Unfurlr shows you the destination of shortened URLs before you click, so you can avoid phishing attacks and other nefarious links.

  • OnStage

    OnStage makes it easy to collaborate on MailChimp campaigns. Instead of sending a test email for editing or approval, just send a link to OnStage and have a real conversation instead.

  • Pictaculous

    Ever wondered what colors to use with an image? Just email a picture to Pictaculous, and we'll send back some color suggestions. Simple as that.

  • Integrate WordPress with Twitter and Facebook, so you can collect everything people are saying about your blog in one place.
