Traditional platforms say no cold email.
We say yes.

Infrastructure

Dedicated infrastructure, built for your volume.

Shared platforms put your sending reputation at the mercy of everyone else on them. SuperSend gives you dedicated servers, IPs, and senders, and operates them for you.

How the infrastructure works
Dedicated Sending Capacity
Isolated nodes and dedicated IPs for your volume
Sender Identities Provisioned
Approved domains, aliases, and rotation managed for you
Warmup and Ramp
Managed reputation ramp on dedicated infrastructure before production volume
Managed Sending Health
Sender health monitored and managed by SuperSend
SuperSend manages the sending layer. You focus on the campaign.
Acceptance-aware sending
Pace driven by live delivery feedback, not how fast your campaign queue wants to enqueue
Per-domain optimization
Adaptive rate per recipient domain from acceptance and deferral signals in real time
Closed-loop tuning
Tightens when acceptance slips; ramps when signals recover. Continuously from SMTP events
Volume follows delivery signals, not static rate limits in settings.
Delivery optimization

Delivery optimized at every layer

High-volume tools optimize queue speed. SuperSend tunes pace from live acceptance and deferral signals, per recipient domain, so volume matches what mailbox providers will actually deliver.

How dedicated infrastructure and delivery optimization work together
Deliverability

Know why every email lands. Or doesn't.

At scale, “your bounce rate is 4%” tells you nothing useful. SuperSend tells you exactly why each bounce happened, runs placement tests on your real senders (not synthetic health scores), and monitors domain health with one-click fixes.

Placement tests and domain health show you what is happening. Adaptive pacing uses those signals and live SMTP feedback to tune send rate before problems show up in a test.

Super Inbox

One inbox for every sender. Every reply.

When you're sending across hundreds of senders and dozens of subdomains, replies scatter. SuperSend consolidates every reply across every identity into one inbox, AI-categorized and searchable.
