Email infrastructure for reliable product communication

Imly is CapEngage's dedicated cloud Mail Transfer Agent (MTA) and Email Service Provider infrastructure. Unlike standard SaaS email tools that rely on shared IP pools, Imly provides dedicated IP allocation, automated deliverability shielding, and high-throughput sub-second SMTP/REST APIs built specifically for high-volume senders and enterprise developers.

Migration is seamless. Imly supports standard SMTP relay credentials and drop-in REST API parameter mappings. Most engineering teams switch over their transactional sending pipelines within a single afternoon with zero downtime.

Imly features an automated Algorithmic Warmup Engine. When you onboard a new dedicated IP, Imly automatically schedules and paces sending volume across major ISPs (Gmail, Yahoo, Outlook) over a 2–4 week period, protecting your sender score and ensuring primary inbox delivery.

Yes. Imly supports dedicated IP Pool Isolation and Sub-Accounts. You can assign transactional emails (OTPs, billing receipts, security alerts) to a dedicated high-reputation IP pool while routing marketing campaigns through a separate pool.

Imly provides real-time webhooks for 12+ granular event types including dispatch latency, accepted, delivered, hard bounce, soft bounce, spam complaint, open, click, and unsubscribe. All logs are searchable and retained with detailed SMTP diagnostic codes.
