Imly ESP
Imly ESP is CapEngage's proprietary cloud Mail Transfer Agent (MTA) and Email Service Provider infrastructure, engineered for high-volume senders with dedicated IP pools, automated deliverability shielding, and sub-second dispatch APIs.
Extended Definition
Unlike legacy shared SaaS email services (which co-mingle thousands of senders onto shared IP addresses where a single bad actor can destroy inbox placement for everyone), Imly ESP provides isolated dedicated IP pools, custom sending domains, sub-second SMTP and REST dispatch APIs, and multi-tenant sub-account hierarchies for enterprise organizations and marketing agencies.
How It Works
Imly operates a distributed, horizontally scalable cloud MTA cluster. Transactional OTPs and marketing broadcasts are segregated into distinct IP pools. The engine automatically negotiates TLS 1.3 encryption, manages connection pooling and throttling per ISP (Gmail, Yahoo, Microsoft), validates SPF/DKIM/DMARC/BIMI signatures, and logs 12+ real-time event webhooks.
Why It Matters for Enterprise Teams
Optimizes primary inbox delivery rates, eliminates noisy-neighbor reputation degradation, and provides sub-second dispatch latency for mission-critical transactional notifications.
Autonomous Execution in CapEngage
Imly ESP is the native email backbone of CapEngage. It features drop-in REST and SMTP migration from SendGrid, Mailgun, or Amazon SES with zero downtime and automated dedicated IP warming.
