DataTrue

DataTrue helps you maintain the integrity of your digital marketing data by automating the testing and validation of your tracking tags. Instead of manually checking if your analytics, conversion, and marketing pixels are firing correctly, you can set up automated workflows that simulate user journeys across your website. This ensures that your data remains accurate even after site updates or code changes.

You can also use the platform to monitor data privacy compliance, ensuring that tags only fire when users have provided the necessary consent. It is designed for enterprise marketing teams, data analysts, and agencies who rely on high-quality data to make informed business decisions. By catching tracking errors before they impact your reports, you save time on troubleshooting and gain confidence in your marketing attribution.

MailStore

MailStore helps you take full control of your company's email data by creating 1:1 copies of all emails in a central archive. You can secure large volumes of data permanently while meeting complex legal retention requirements and GDPR obligations. By offloading emails from your active server to the archive, you significantly reduce the workload on your IT infrastructure and eliminate the need for unreliable PST files.

You can empower your team with lightning-fast full-text searches for emails and attachments, accessible directly through Outlook or a web browser. Whether you use Microsoft 365, Google Workspace, or an on-premise Exchange server, the software integrates into your existing environment. It is specifically designed for small and medium-sized businesses looking for a reliable way to prevent data loss and simplify backup processes.
