Our uncompromising structural framework designed to preserve IP reputation, enforce permission-based routing, and protect subscriber inboxes globally.
Mailstine enforces an absolute, zero-tolerance policy regarding unsolicited commercial email, more commonly known as Spam. Delivering communications through our infrastructure requires explicit, verifiable consent from every recipient. We actively monitor outbound traffic layers to protect our collective deliverability health.
To utilize Mailstine’s broadcasting tools, you must be able to prove, at any given moment, the exact point of origination and consent for your subscriber list. Valid consent architectures include:
Users who submitted their address through a web form, specifically requesting marketing or notification materials from your registered domain.
Customers who have engaged in a recent (within 12 months) commercial transaction with your business, acknowledging communication terms.
Routing pipelines on our platform will immediately flag and quarantine accounts attempting to import lists from the following non-compliant origins:
Mailstine forces compliance structurally. Every campaign payload processed by our rendering engine is automatically appended with a single-click unsubscribe loop.
System Protection: Subscribers who click the mandatory opt-out hyperlink are instantly classified onto a global suppression queue. Mailstine blocks any subsequent attempt to route messages to suppressed variables, even if the sender attempts a secondary list upload.
Our internal reputation engines constantly map campaign delivery performance. Account capabilities may be restricted, throttled, or permanently closed if your account generates metrics reflecting unsolicited activity:
Rates exceeding 0.1% via ISP feedback loops.
Sustained unknown-user limits crossing 5%.
Hitting known global honeypot routing addresses.
If you believe you have received an unsolicited communication traced to Mailstine’s infrastructure, we encourage immediate reporting to our network security desk so our engineers can trace, verify, and terminate the offending node.
Please forward full email headers for investigation.
