Mailvelope vs OpenText Core Email Message Privacy

Mailvelope adds client-side end-to-end PGP encryption to supported webmail. Its browser add-on works with Gmail, Outlook, WEB.DE, and other webmailers, and can encrypt or decrypt attachments within email, including with PGP/MIME. While composing, it can detect a recipient’s public key; signature mismatches can help identify phishing attempts. Users can export keys, manage multiple keyrings, and use Mailvelope or other key servers. The free private-user offering is independent from Google, but lacks PGP/MIME, Google Workspace integration, and customer service. Mailvelope states that it complies with GDPR and EU privacy laws. Business plans include a 14-day free trial without payment data. Monthly billing costs €3 per user per month; annual billing costs €32.40 per user per year. Paid subscriptions auto-renew and can be cancelled anytime. Business integrations include professional or premium email support options. Mailvelope is available as an extension and through the web.

OpenText Core Email Message Privacy secures sensitive messages and files while allowing senders to control access throughout a message’s lifecycle. Through Outlook or a secure portal, users can send attachments up to 100 GB per message. Digital-rights controls can restrict viewing, replies, forwarding, and expiration, while senders can later adjust or revoke rights. Recipients open secure messages through browser or mobile web links without installing software or a native app. Delivery, opens, downloads, and signatures are tracked in real time for auditability. Messages and files uploaded to the portal are encrypted at rest with AES 256. The service supports legally binding electronic signatures, Outlook and Single Sign-On integrations, and corporate branding. It is delivered as SaaS without additional infrastructure and works with hosted, on-premises, and hybrid email systems. OpenText describes it for managed service providers protecting small and medium-sized businesses. Pricing is on request; there is no free plan, and only professional users consume licenses while guest recipients are free.
