Widget vs. RESTful Integration Methods

  • Widget API (most popular)
  • RESTful API
  • Benefits:
  • 1.) Simple Integration - takes less than 10 minutes. Here's a quick demo.
  • 2.) We maintain the test results page. Updates are included in each new release
  • 3.) A very efficient way to determine the interest level of your user base.
  • Benefits:
  • 1.) More complex integration, but you have complete control over the branding, messaging and workflow.
  • 2.) Updates and new features must be integrated by your team.
  • What is included in a test?

    A single test includes a preview in each of our supported email clients, SPAM analysis, code analysis, CSS conversion, and our tips and tricks.

    If you wish to provide your customers with a SPAM analysis or email preview only, it's still considered one test.

  • How long does a test take?

    Screen captures will start to appear within 20 seconds and your users can peruse their results as they come in.

    The average wait time is between 2-5 minutes for each test to complete. If it takes longer than 1 minute per email client, you will not be charged for the test.

  • Do you have a sandbox?

    We sure do and it's free! There are no hidden integration or support fees and we are glad to help with any questions you might have along the way.

    If you would like to review our documentation and code samples, feel free to complete our API form below and we will get back to you within 24 hours.

  • How complex is the integration?

    It takes less than 10 minutes to integrate our Widget API and as we release new features, we handle all of the maintenance updates for you. Check out this online demo to see just how easy it is.

    The RESTful API provides you with complete control over your customer workflow, therefore the integration timeline is based on your internal resources and specifications.

  • Does the pricing change each month?

    NOPE - your rate will be locked in and will not fluctuate each month based on your usage.

    Just complete our API form below and will provide you with an estimate within 24 hours. Our quotes are based on our prediction for your monthly usage.

  • No long term contracts.

    There are no long term commitments, you can cancel your account at anytime. Rates are evaluated on a yearly basis based on overall usage.

Please enter the number of users who will be provided access to our testing service. For instance, lets say you have 5,000 total sign-ups and 200 of them are monthly subscribers. If you plan to release our service to subscribers only, you have 200 active users.

If you plan to use our API for internal purposes, the term "active" in this case would apply to the number of users who will be processing tests on a regular basis.
