Enterprise email infrastructure for outbound at scale
9 services + 8 providers + 4-phase warmup + deliverability intelligence
LeadsLogix Email Marketing is a 9-service platform built for cold outreach at scale. Connect 8 email providers (Google Workspace, Microsoft 365, Zoho, SES, Postmark, Mailgun, SendGrid, SMTP), warm up new mailboxes through 4 phases, monitor deliverability with 9 DNS checks, and auto-pause on bounce or spam spikes. Multi-tenant isolation and idempotent delivery guarantee safety.
Why Email Infrastructure Is Your Bottleneck
9-Service Architecture for Enterprise Email
Each service is independent with its own data store, communicating via Redis event bus. Failures in one service don't cascade. Multi-tenant isolation keeps accounts separated.
8 Email Providers
Google Workspace, Microsoft 365, Zoho, Amazon SES, Postmark, Mailgun, SendGrid, and custom SMTP. Automatic failover between providers.
4-Phase Warmup
Seed (days 1-3), Ramp (4-14), Stabilize (15-21), Full (22+). Configurable start volume and daily increment. Auto-pause on anomalies.
9-Check Deliverability
SPF, DKIM, DMARC, PTR, DNSBL (20+ lists), BIMI, ARC, TLS, and composite score (0-100). Monitor and fix before issues arise.
Priority Queue
Redis sorted-set queue: 1=transactional, 9=bulk. Smart routing selects the healthiest mailbox with available quota.
Bounce Management
Automatic classification: hard bounce, soft bounce, block, spam complaint. Bounce > 3% auto-pauses campaign. Spam > 0.1% auto-pauses.
Multi-Tenant Isolation
Per-tenant SQLite databases, contextvars-based scoping, and isolated credential vaults. No data leaks between accounts.

Each stage processes data sequentially with full checkpoint/resume capability.
