Company: AISDR, an AI SDR agent that finds in-market buyers using real-time signals and books meetings
Problem: Programmatic inbox provisioning at scale, without a human in the loop
Result: Hundreds of PostNuvia inboxes in production, sending thousands of emails per week
Stack: PostNuvia + AISDR
What AISDR Is
AISDR is an AI SDR agent that focuses on lead quality over volume. It finds people across the web in real time using buying signals, researches each prospect, and reaches out across email and LinkedIn with messages that read like a real rep wrote them. Replies are qualified by the agent, and meetings get booked when prospects are ready to talk.
The deliberate, research-first approach is how AISDR differentiates from AI outreach tools optimized for volume. Their public messaging is direct about it: outbound fails the moment relevance becomes optional.
The Problem
For an AI SDR operating at scale, the email infrastructure has to handle two things. Outbound at volume that stays deliverable. And inbound threading so prospect replies route to the right conversation and the agent can respond in-thread.
The central constraint for AISDR was inbox provisioning. They needed automatic inbox creation without a human in the loop.
Why PostNuvia
AISDR went with PostNuvia because the platform covered every feature their flow needed. Programmatic inboxes, send and receive, webhooks for real-time inbound, IMAP and SMTP.
"PostNuvia is a YC company. It has simple documentation with all needed features for our flow."
