Email Delivery Platform
Our SaaS product for high-volume email operations is offered with tailored setup and manages more than 50 million subscriber records. It brings AI-assisted content preparation, audience segmentation and delivery tracking together in one platform.
The challenge
Keeping high-volume delivery under control
High-volume email operations require sending speed, audience engagement and sender infrastructure to be monitored together. Identifying invalid addresses and preventing excessive messages to the same subscriber are also part of this process.
We developed the platform to manage these steps in a shared system, from content preparation to delivery feedback. The product supports multiple customers, with setup and configuration tailored to their operational needs.
What we built
- 01
Dynamic delivery management
Sending speed and delivery behavior are monitored. Traffic can be slowed, paused or increased according to infrastructure conditions.
- 02
Engagement-based segmentation
Opens, clicks and delivery events receive different weights to update subscriber scores. Audience segments are based on these scores and recent interaction times.
- 03
AI-assisted content
Content is analyzed for language that may increase spam risk, with suggestions for improvement. AI can also assist with subject line creation.
- 04
Subscriber and list health
Invalid addresses, complaints and unsubscribes are tracked. Organization-level frequency rules limit the number of messages sent to each subscriber.
The solution
From content to delivery in one platform
We brought content preparation, subscriber management and delivery infrastructure into a single workflow. AI can suggest improvements to language that may increase spam risk and assist with subject line creation.
Campaigns can use multiple domains, senders and subject lines. Messages are sent in batches within defined time windows, with sending speed and pauses adjusted to infrastructure behavior.
A SaaS product with tailored setup
The platform is one of Code64’s SaaS products in active production use. We assess each customer’s sending volume, infrastructure and operational rules to provide tailored setup and configuration.
Organizations can define communication frequency rules across campaigns that share a subscriber pool. These rules limit the number of messages a subscriber receives from different newsletters.
Platform scope
| Area | Scope |
|---|---|
| Content preparation | AI-assisted content analysis and subject line generation |
| Sending resources | Multiple domains, senders, subject lines and sending IPs |
| Traffic management | Scheduled batch sending, speed adjustment and temporary pauses |
| Audience segmentation | Subscriber groups based on engagement scores |
| Delivery and list health | Tracking delivery, opens, clicks, complaints, unsubscribes and invalid addresses |
| Communication rules | Organization-level sending limits per subscriber |
| Infrastructure monitoring | Sender domain and IP reputation checks |
Production scale
The platform manages more than 50 million subscriber records. One high-volume customer alone sends approximately 5–6 million emails per day across 8 sending IPs.

Delivery management informed by feedback
Delivery, open, click, bounce and complaint events are processed in real time through webhooks. Different event weights and recent interaction times update each subscriber record’s score. These scores inform future audience segments and delivery decisions.
When sending speed drops below its expected level, the system treats it as an early health signal. Traffic can be slowed or paused, then increased again as conditions improve.
Addresses reliably identified as invalid are removed from the active sending pool. Complaints and unsubscribes are processed automatically, while domain and IP reputation are also monitored through external checks such as MXToolbox.
