Latest improvements to Rebound’s Javascript API

Rebound's Javascript API now includes a couple of new features that make it easier to use for email-crucial workflows and single-page apps. We’ve introduced a new method(window.Rebound.check()) for explicitly checking an email address whenever you want instead of only on page load. We’ve also introduced an option to continuously run checks in the background without requiring users to reload the page.

Repeat config option

To continuously check an email address, add the repeat option to the config object. repeat accepts any number above 5000 milliseconds. We recommend using it sparingly for workflows crucial to email such as account activation or password reset pages.


window.Rebound.check(config)

This method accepts the standard config object as the first argument. This is ideal for letting your customers know about delivery issues based on an action they took in your app. Take a look at our CodePen example and learn how to check an email address when a form is submitted using Javascript.
