Secure, Compliant, and fully automated – right from the Add-In

Protecting sensitive documents like invoices, contracts, and certificates has never been easier. SerienmailPro automatically encrypts your PDF attachments using password protection – controlled via Excel and sent directly from Outlook. Whether you assign passwords manually or generate them automatically, your communication stays secure and GDPR-compliant without disrupting your workflow.

Why PDF protection matters

When sending documents such as invoices, certificates, or official statements, it’s essential to ensure that the content cannot be altered afterwards. In other words, your PDF files must be write-protected. SerienmailPro offers a reliable solution: the add-in automatically protects your PDF files from unauthorized editing – directly from your Excel data source.
