Official Platform Statement
"LedgerNotify is a strictly transactional email infrastructure provider for financial workflows. Marketing and unsolicited messaging are not permitted."
From secure SMTP relay to intelligent bounce handling — every feature is purpose-built for billing systems, accounting platforms, and financial SaaS.
Isolated sending IP addresses assigned per account. Prevents cross-contamination from other senders. Custom PTR records and rDNS configured.
Signed API keys with granular permissions: send-only, read-only, webhook, admin. Key rotation without downtime. IP allowlist enforcement.
High-throughput SMTP gateway with TLS 1.3 mandatory. 587 and 465 port support. Compatible with any billing platform or ERP.
Full email authentication stack configured automatically. Custom DKIM selectors per domain. DMARC policy enforcement with failure reporting.
Hard bounce auto-suppression within 60 seconds. Soft bounce retry logic with configurable backoff. Suppression list sync via API or webhook.
Real-time delivery events: sent, delivered, bounced, opened, clicked. Webhook delivery for integration with your data warehouse.
Per-account and per-IP sending limits. Automatic throttling prevents abuse. Configurable burst allowances for billing cycle events.
Machine learning models detect anomalous sending patterns. Unusual volume spikes trigger automatic holds pending review.
Immutable, cryptographically signed log entries for every email event. 7-year retention available for financial compliance mandates.
FBL (Feedback Loop) integration with major ISPs. Complaint rate monitoring with sub-0.1% SLA. Auto-suppression on complaint receipt.
Double opt-in verification required for all recipient accounts. Consent timestamp stored with each send record. Erasure support for GDPR.
AES-256 encryption at rest. TLS 1.3 in transit. No plaintext storage of email content. Zero-access architecture for message bodies.
LedgerNotify integrates with your existing billing infrastructure in hours, not days. Our REST API, SMTP relay, and SDK options fit any stack.
A payment is captured, invoice generated, or subscription renewed in your billing system. Your application detects the event.
Your backend sends a signed POST request to our REST API or SMTP relay with the recipient, template ID, and transaction data.
LedgerNotify verifies the recipient has an active account, is not suppressed, and the sending pattern is within normal thresholds.
Email is composed, signed with DKIM, and dispatched via dedicated IP. Delivery events are logged and webhooks fired in real-time.
Send a payment confirmation in a single API call. SDKs available for Node.js, Python, Ruby, PHP, and Go.
Every layer of LedgerNotify's infrastructure is designed to meet the security standards required by financial services, billing platforms, and regulated industries.
All data transmitted between your application and LedgerNotify infrastructure is encrypted using TLS 1.3. Older protocols (SSLv3, TLS 1.0, TLS 1.1) are permanently disabled. Certificate pinning available for enterprise customers.
SMTP relay accepts connections only on port 587 (STARTTLS) and 465 (SMTPS). STARTTLS is enforced — plaintext fallback is not permitted. Authentication required for every connection.
API keys are scoped, rotatable, and hashed at rest using bcrypt. Keys carry minimum-privilege permissions. IP allowlist enforcement available. Compromised keys can be revoked instantly without service interruption.
Enterprise accounts receive dedicated sending IP pools isolated from other customers. This protects sender reputation and ensures deliverability is not impacted by third-party sending behavior.
Automatic rate limiting enforced per API key, per account, and per IP. Burst allowances configurable for billing cycle events. Prevents abuse and protects platform integrity.
ML-based anomaly detection monitors sending patterns in real time. Unusual volume spikes, high bounce rates, or suspicious recipient patterns trigger automatic review holds.

Effective Date: January 1, 2025 — This policy governs all email activity conducted through the LedgerNotify platform.
LedgerNotify exclusively processes system-generated transactional emails triggered by verified financial events. A transactional email is defined as a message sent to an individual who has an active, registered account and is sent as a direct result of a specific action taken by or affecting that account holder. Examples of permitted email types include:
No other email types are permitted. Marketing campaigns, newsletters, cold outreach, and promotional blasts are strictly prohibited.
All recipients of emails sent through LedgerNotify must be existing customers with active registered accounts on the sending platform. Emails may not be sent to:
LedgerNotify requires that all recipient accounts be created through a double opt-in process. This means:
Senders must maintain records of consent for each recipient and must be able to produce these records upon request by LedgerNotify's compliance team, regulators, or in response to a valid legal process. Consent records must include the date and time of opt-in, the method of consent collection, and the version of the privacy policy presented at the time of registration.
LedgerNotify maintains a platform-wide bounce rate SLA of under 2%. Individual sender accounts that consistently produce bounce rates above 2% will receive automated warnings and may have sending paused pending list hygiene review. Hard bounces are auto-suppressed within 60 seconds of bounce receipt.
The platform maintains a complaint rate SLA of under 0.1%. This is enforced via FBL (Feedback Loop) integration with major ISPs including Gmail, Yahoo, and Outlook. Accounts exceeding 0.1% complaint rate will receive immediate notice. Accounts reaching 0.5% will be suspended pending review.
LedgerNotify maintains automated suppression lists including hard bounces, spam complaints, and manual unsubscribe requests. These lists are enforced at the infrastructure level — suppressed addresses cannot be emailed regardless of the sending request. Suppression lists are synced in real-time and can be retrieved via API.
Upon receipt of a spam complaint, LedgerNotify will:
Violation of this Email Sending Policy may result in: temporary sending suspension, permanent account termination, forfeiture of prepaid credits, and reporting to relevant authorities where required by law. LedgerNotify reserves the right to audit any account at any time to verify compliance with this policy.
Pay only for what you send. No monthly minimums on Starter. Volume discounts on Growth and Enterprise tiers. All plans include compliance infrastructure at no extra cost.
All LedgerNotify pricing tiers cover strictly transactional email delivery. Marketing email, cold outreach, and bulk campaigns are not available at any price point. Attempting to use this platform for non-transactional purposes violates our Acceptable Use Policy.
For early-stage billing platforms
For scaling subscription businesses
For large financial platforms and banks
LedgerNotify was founded to solve a specific problem: financial SaaS companies needed a dedicated, compliant email infrastructure that understood the strictures of regulated financial communication.
General-purpose email platforms were built for marketers. LedgerNotify was built for CFOs, CTOs, and compliance officers. We understand that a missed invoice email is a failed payment. A delayed billing alert is a support ticket. A non-compliant send is regulatory exposure.
We exist to take that risk off your plate. Our infrastructure delivers transactional financial email with the reliability, auditability, and compliance that regulated industries demand — and nothing else.
We do not offer marketing email. We do not support cold outreach. We do not allow purchased lists. This is a feature, not a limitation.

LedgerNotify operates exclusively as a transactional email infrastructure. Unlike general-purpose email platforms, we do not offer marketing email tools, list management features, campaign builders, or any functionality that would enable bulk unsolicited messaging. This is an architectural decision made to protect recipients and maintain the highest possible deliverability standards.
We implement the following technical controls to prevent spam:
All emails sent through LedgerNotify must comply with the CAN-SPAM Act. Transactional emails that contain any promotional content lose their transactional exemption and are subject to the full requirements of CAN-SPAM. LedgerNotify enforces transactional content purity through template review and monitoring.
For emails sent to data subjects in the European Union, senders must have a valid lawful basis for processing (typically contractual necessity for transactional emails). LedgerNotify requires senders to maintain records of consent and to honor erasure requests. We provide APIs for consent and suppression management to support these obligations.
Recipients who believe they have received an unsolicited email from a LedgerNotify customer may report it to abuse@ledgernotify.com. We will: acknowledge receipt within 4 business hours, investigate within 24 hours, suppress the recipient immediately upon complaint receipt, and take action against the sending account if a violation is found. Complaints are never ignored.
Any customer found to have used LedgerNotify for spam will face: immediate account suspension, forfeiture of prepaid credits, permanent ban from the platform, and where required by law, referral to relevant authorities. We cooperate fully with law enforcement investigations involving email abuse.
