MailBridge Pro powers secure, compliant automated emails — account confirmations, password resets, billing invoices, and order notifications — with 99.9% delivery uptime and built-in regulatory compliance.
Our infrastructure is purpose-built for system-generated, opt-in transactional messaging — not bulk marketing.
Purpose-built sending infrastructure with dedicated IP pools, domain reputation management, and feedback loop integrations with all major inbox providers. Your transactional emails reach the inbox every time.
Drop in SMTP credentials or integrate with our RESTful API in minutes. SDKs available for Node.js, Python, PHP, Ruby, Go, and Java with comprehensive documentation and sandbox testing environments.
Monitor delivery rates, bounce categories, open confirmation, and click tracking per email event. Webhook callbacks notify your application instantly on delivery, bounce, or complaint events.
All data is encrypted in transit using TLS 1.3 and at rest using AES-256. Multi-region redundancy ensures your email delivery continues without interruption. SOC 2 Type II audit-ready architecture.
Built-in double opt-in verification flows ensure recipients have explicitly confirmed their email and consent to receive messages. Confirmation tokens, expiry handling, and re-send logic included.
Automated abuse detection flags unusual sending patterns. Unsubscribe headers and list-unsubscribe mechanisms are automatically appended where required by law. Complaint rate thresholds trigger proactive account review.
From API key to production delivery in under 30 minutes. Our compliance checks run automatically at every step.
Sign up, verify your business domain, and complete our Acceptable Use Policy agreement. Your account is reviewed before live sending is enabled.
Add SPF, DKIM, and DMARC DNS records to authenticate your sending domain. Our setup wizard guides you through each record with verification checks.
Use your API key with our REST API or SMTP credentials directly in your application stack. Test in sandbox mode with no risk before going live.
Track deliverability in real time from the dashboard. Set webhook alerts, review analytics, and scale your sending volume with your plan as your business grows.
No setup fees. No hidden charges. Cancel anytime. All plans include full compliance tooling.
Ideal for startups and small applications with moderate transactional email volume.
For growing businesses needing higher volume, priority support, and advanced analytics.
For large-scale platforms and enterprises with high volume, SLA guarantees, and compliance requirements.
Every account, every email, every send event is governed by our strict compliance framework. We enforce it automatically, not by trust.
All emails processed through MailBridge Pro include required sender identification, valid physical postal address, and clear subject lines. Our platform enforces CAN-SPAM Act requirements automatically on every outbound message originating from US-based senders.
We process personal data only as described in our Data Processing Agreement. Recipients located in the EEA receive additional protections including data minimization, right of erasure, and access request handling. GDPR-ready suppression lists are enforced globally.
MailBridge Pro exclusively supports transactional emails to recipients who have explicitly opted in. No purchased lists, no cold outreach, no unsolicited bulk messaging of any kind is permitted. Violations result in immediate account suspension.
Our abuse monitoring system analyzes sending patterns, complaint rates, and bounce behavior in real time. Accounts exceeding spam complaint thresholds are automatically placed under review. Confirmed violators are permanently suspended and reported to relevant authorities.
Machine learning models flag anomalous sending behavior including sudden volume spikes, unusual geographic distribution, and high invalid-address ratios. Our trust and safety team reviews flagged accounts within 4 business hours.
Where applicable, MailBridge Pro appends RFC-compliant List-Unsubscribe headers automatically. Accounts sending transactional email categories that require opt-out mechanisms must implement them within their application and provide proof of compliance during onboarding.

View Plans & PricingMailBridge Pro is a US-based transactional email infrastructure company headquartered in Arlington, Virginia. We were founded with a single mission: to provide businesses with a reliable, fully compliant platform for delivering critical system-generated emails — and nothing else.
Unlike general-purpose email service providers that blend transactional and marketing email into a single platform, MailBridge Pro is dedicated exclusively to transactional messaging. We believe transactional email infrastructure deserves a specialized provider with purpose-built compliance tools, dedicated IP infrastructure, and a team that understands the regulatory landscape.
Our platform serves SaaS companies, e-commerce platforms, fintech applications, healthcare portals, and enterprise software teams across the United States and internationally. Every customer agrees to our Acceptable Use Policy and undergoes a domain verification process before live sending is permitted.
We operate under a strict opt-in-only policy. No purchased lists. No cold outreach. No bulk unsolicited email of any kind. This is not just a policy — it is the foundation of our business model and the reason our customers maintain industry-leading deliverability rates.
Have a question about our platform, pricing, or compliance requirements? Our team typically responds within one business day.
Notice: MailBridge Pro does not respond to requests to send unsolicited bulk email, purchase email lists, or conduct cold outreach campaigns. Such requests will be disregarded and may result in IP-level blocking.
