CartStack 5.0 is now live! While the engine delivering results remains as powerful as ever, everything underneath has been completely rebuilt. We've created an entirely new infrastructure designed to move faster, evolve with your feedback, and support the next generation of tools to keep your recovery strong over time.

What's New:

A Clearer, More Actionable Dashboard

Performance is easier to understand at a glance. With cleaner data and simpler visuals, you can see how each campaign contributes to recovery while tracking abandonment and recovery in real time.

A More Intuitive Campaign Builder

Everything you're used to is still there, just organized better. The refreshed builder feels smoother and more intuitive without changing how it works, making campaign creation and management effortless.

A Smarter Campaign Report

Compare performance across different date ranges with the new compare feature, plus visual graphs to help you spot trends and understand performance at a glance.

Built to Move Fast: More Coming Soon

The new infrastructure isn’t just about what’s here today. It’s about what’s coming next. We’ve rebuilt CartStack 5.0 from the ground up so we can ship new features faster than ever before. Over the next few months, you can expect a steady stream of new tools, improvements, and capabilities designed to help you recover more revenue with less effort. We’re just getting started.

We've added a brand new webhook that triggers when a user completes a cart or booking abandonment email sequence (i.e., when the final follow-up email has been sent).

This gives you more control and flexibility with your email strategy. You can use it to:

• Send a 4th email reminder

• Tag or untag users in your ESP

• Prevent conflicting or overlapping messages

This update makes it easier to sync and optimize post-abandonment workflows across your platforms.

We're thrilled to announce that our new pre-send email validation feature has cut bounces by nearly 70%!

This update checks emails for validity every minute, ensuring only active addresses are queued to receive emails before they’re sent. It automatically filters out invalid emails while flagging catch-all, unknown, or error emails for review. Ultimately, this means fewer undeliverable emails, better engagement, and more efficient campaigns for everyone!

Check out the screenshot below for more insights:

One-Click unsubscribe is now an added feature within our cart & browse abandonment email campaigns. This update is in response to Gmail and Yahoo's bulk sender requirements that were updated earlier this year.

With this feature, users can easily unsubscribe without searching for the email footer link, improving user experience while complying with the updated standards of Google and Yahoo.

In your aggregate report, you'll now be able to see your total recovered revenue allowing you to see the total ROI across all of your campaigns.

See screenshot here for example:

Dark Mode Preview's now available within your template library, allowing you to view how your email will appear in dark mode on both desktop and mobile devices.

To see how your email will appear:

• Head to your template library
• Choose the template you'd like to view and click the edit icon
• Next, head to the upper left corner and click the Action dropdown menu.
• Choose "Preview"
• Once in preview mode, you'll be able to toggle dark mode on/off.

We've also compiled a list of resources for you on how to best optimize an email for dark mode.

Conditional Content allows CartStack users to present their customers with the most relevant email content possible, to give you the best chance at recovering a lost sale.

Conditions are predefined by the user & can be based on a number of factors:

• Actions the customer took on your website
• Items added to their cart
• The total value of the abandoned cart
• Product pages viewed
• The region / language of the abandoned customer
• And much more…

Once the conditions are defined, all you need to do is tell our email builder which content to show which segment of recipients, and you’re all set!

If you manage multiple accounts with CartStack, you'll want to check out our new Aggregate Reporting feature! This new report pulls the metrics from all of your accounts & campaigns into one report, making it easy to review performance without logging into each dashboard separately.
