About Mailprotector & Technical Insights
What this service does and the technologies behind it.
Read the tech stack as text▾
Overview: A privacy-forward cybersecurity vendor that uses compliance-friendly European analytics and edge infrastructure to practice the data protection it sells.
What stands out
- Running EU-hosted Matomo alongside Google Analytics suggests active migration toward privacy-compliant measurement, consistent with the zero-trust email security brand.
- Microsoft Advertising rather than Google Ads alone indicates a B2B demand-generation focus on enterprise IT and software buyers.
- No e-commerce or CMS signatures detected, confirming a pure lead-generation and thought-leadership marketing site.
- Cloudflare fronting HTTP/3 shows the company invests in its own site performance and security posture, a credibility signal in the security market.
Technologies mailprotector.com uses
- Piwik PRO Core — EU-hosted Matomo signals privacy-first, data-residency-conscious analytics, mirroring the company's zero-trust, compliance-led email security positioning.
- Microsoft Advertising — Paid search on Bing/Microsoft channels powers B2B demand generation, targeting IT and security buyers rather than consumer traffic.
- Google Analytics — Standard traffic and campaign measurement for the marketing funnel.
- Cloudflare — Edge CDN, WAF and caching protect and accelerate a security vendor's own marketing site.
- HTTP/3 — Modern HTTP/3 delivery signals an emphasis on fast, secure user experience.
How these technologies work together
- Cloudflare runs on HTTP/3 — Cloudflare serves the site over HTTP/3 at the edge, giving the security vendor fast, modern encrypted delivery.
- Google Analytics overlaps with Piwik PRO Core — Two analytics platforms run side by side, likely for migration, privacy contrast, or comparing cookieless EU tracking against Google's reporting.
- Cloudflare works alongside Piwik PRO Core — Edge proxying plus cookieless EU analytics builds a privacy-by-design stack that matches the brand's zero-trust message.
- Google Analytics works alongside Microsoft Advertising — Google Analytics attributes the Bing ad spend, forming the standard paid-search funnel for enterprise security lead generation.
- Microsoft Advertising integrates with Piwik PRO Core — Matomo tracks paid Microsoft ad conversions without third-party cookies, keeping acquisition data in a GDPR-compliant pipeline.

How to fix Mailprotector not working
Mailprotector is an email security service sold through managed service providers. It filters spam, phishing and malware for Microsoft 365 and Google Workspace mailboxes, and offers encryption and archiving. Find your symptom below. Most problems come from a sign-in, a filter rule, a mail routing or domain setting, or the platform itself. Check the quarantine before you release a message, and never release a message you do not trust.
Jump to what you are seeing
Email Delivery
Email to or from a domain does not arrive, or it arrives late.
- Check the mail routing and the domain's records have not changed recently.
- Check the message is not held in quarantine, and release it only if it is safe.
- Check status.mailprotector.com, and send the sender domain and the time to your provider.
Login Failed
Sign-in is refused.
- If the message says the password is wrong, reset it through the official route and check spam.
- Check you are using the partner or tenant account your provider set up.
- Try a private window to rule out an old session.
Website Down
The Mailprotector website does not load for you.
- Open the page in a private window and on another network.
- Check status.mailprotector.com for an active incident.
- If only your network is affected, ask IT to check the firewall.
Spam Filter Issues
Good email is blocked as spam, or spam gets through.
- Check the filter rule and the allow list for the sender domain.
- Review a sample of the blocked messages before you change the rule.
- Check status.mailprotector.com, and tell your provider the sender domain and the time.
Encryption Failed
An encrypted message does not send, or the recipient cannot open it.
- Check the recipient's address is correct, and that they have the instructions for the encrypted message.
- Check the encryption policy applies to that domain.
- Check status.mailprotector.com, and send one test encrypted message to your own address.
API Error
Calls to the Mailprotector API fail or return an error.
- Check the status code. An access error usually means the key is wrong, too many calls means you should slow down, and a server error means a service-side problem.
- Confirm the key has not been revoked and is for the right tenant.
- Retry with a growing delay, and check status.mailprotector.com if several calls fail together.
Still not working?
Contact your managed service provider, who manages the tenant, first. For a platform-wide problem, contact Mailprotector support through the help option in the platform or on its website. Have your organisation or tenant name, the sender or recipient domain (not the full addresses), the exact error text, and the time with your time zone. Never send passwords, API keys or message contents in a support message. Live incident updates are on status.mailprotector.com.
Most email-security problems come from a filter rule, a routing setting or a quarantined message, and they usually clear once that is checked. The status page shows live incidents, so you can see whether the problem is on Mailprotector's side.
