Our automatic A/B testing feature makes it easy to test different subject lines, sender details and even totally different email designs. Tell us what to test, how you want us to pick the winner and we'll do the rest.

The best part is, it takes a few clicks to set up and you learn something about your audience every time you do it.

Social Sharing

Our social sharing feature makes it easy for your subscribers to share your campaigns on Twitter and Facebook. With a single click you can add a "Like" or "Tweet" button to your campaign and it's ready to be shared.

We'll show you a detailed report on which subscribers shared your campaigns, and even what they said about you when they did it.


Autoresponders make it easy to stay in touch with your subscribers without lifting a finger. Quickly build and schedule automated welcome messages, birthday greetings and other date-based campaigns. Send single emails or a sequence over time.

Keep it Relevant

To get the best results in email marketing, it's important to send relevant stuff to the right people at the right time. Our segmentation and personalization tools make it easy to focus your efforts where they count most.

  1. Segmentation

    Target subscribers using data you have about them, location, or past campaign activity like whether they opened an email.

  2. Triggered messaging

    Automatically email people when they meet criteria you set, like a recent purchase or their membership expiring.

  3. Personalized content

    Send custom content to every subscriber by personalizing it with whatever information they have shared with you.

  4. Webhooks

    Automatically sync subscriber activity with your own records as they happen with our subscriber webhooks.

Spam Testing

Getting your email delivered isn't just about choosing a great email service provider. Your content might be triggering filters and not being read. Instead of just scanning your content for "spammy words", we’ll pass your email through real spam filters and firewalls and tell you which ones it passes, and which failed.
