Cold email infrastructure built for high-volume B2B lending.
You shouldn't need thousands of mailboxes to reach small businesses at scale. Dedicated sending infrastructure, parallel execution, and a managed ramp so your pipeline keeps moving.
Built for lenders sending 300k to millions of emails per month.
The mailbox stack breaks at scale.
It starts small. A few hundred domains, a few thousand mailboxes, someone manually routing inboxes to campaigns. Then you try to grow, and the infrastructure becomes the bottleneck.
When your TAM is millions of small businesses across the US, you can't afford to have the email stack be the thing slowing you down. SuperSend builds and manages dedicated infrastructure for high-volume SMB outreach, so you scale outreach without scaling the chaos.

- Mailboxes disconnecting every 30–90 days (OAuth expiry)
- Campaigns starving each other for inbox capacity
- Manual routing: turn off A–D for this campaign, E–H for that one
- Domains flagged with no automated failover
- Someone hired to keep the email stack from breaking
- Thousands of mailboxes, still hitting a volume ceiling
Everything you need. One platform.
We build, warm, and manage the infrastructure. You run campaigns through the sequencer. One platform owns the whole stack, from dedicated IPs to your Salesforce pipeline.
Dedicated servers + isolated IPs
Your sending reputation is yours alone. No shared pools, no neighbor risk. Volume fans across dedicated IPs scoped to your volume.
Server-level failover. Volume never stops.
If an IP or domain gets flagged, traffic reroutes instantly to backup servers already warmed and ready. You never see a dip.
Parallel campaign execution
One sender profile across every campaign. Our supply-and-demand algorithm allocates capacity in real time. No campaign starves another.
Managed warmup on our network
30,000+ proprietary Google and Outlook mailboxes. Infrastructure is warmed before the first production email goes out.
Live inbox placement by provider
See exactly where emails land, inbox or spam, broken down by Gmail, Outlook, and Yahoo. Know what is working before it costs you.
AI reply routing → your CRM
Replies are auto-categorized (interested, applying, not now) and routed to Salesforce or your CRM via API. Sales only sees qualified leads.
How your sending infrastructure is structured.
Volume fans across multiple isolated servers and dedicated IPs, all scoped and pre-warmed for your team. If one node has a deliverability issue, traffic reroutes automatically. Sending never stops.
“100 form completions a day became 350.”
Same contacts. Same sending volume. The only change was moving to dedicated infrastructure and switching from HTML templates to plain text with AI-powered reply routing. The funnel didn't need more leads. It needed emails that actually landed.

You send 300k+ emails per month, or plan to
Below that threshold, dedicated infrastructure is harder to justify. Above it, the ROI is usually clear within the first conversation.
Your TAM is millions of small businesses
If you're reaching SMBs across the US, your volume ceiling on a traditional mailbox stack is low. Dedicated infrastructure removes it.
You're done managing the mailbox chaos
Hundreds of domains, thousands of reconnects, manual campaign routing. If someone on your team is keeping the email stack alive full time, that cost is invisible on your P&L.
