The Only Private Infrastructure
Built for Cold Email at Scale.

Q: How do Aerosend inboxes have such a high email deliverability?

At Aerosend, we have combined everything that affects deliverability into one private infrastructure. Isolated infrastructure, aged premium IPs, dedicated servers, dynamic IP rotation, and domain burn alerts work together to keep inbox placement high.

Q: How does Aerosend adapt to cold email changes?

We continuously monitor and test for market changes. Our deliverability engine watches IP health, inbox placement, warmup pools, and bounce patterns, proactively rotating IPs and adjusting configurations before issues affect your inboxing.

Q: What is the difference between private infrastructure and Google/Outlook inboxes?

Private infrastructure is designed for cold email: no shared reputation, no bans, and controls that protect deliverability. Google and Outlook are built for regular mail and can ban or spam-box cold outreach, making them unreliable at scale.

Q: Do I need an email sequencer with Aerosend inboxes?

Yes. Aerosend inboxes work best when connected to an email sequencer so you can run structured, multi-step outreach while our infrastructure maintains deliverability.

Q: Why is there a 10-domain slot minimum?

Every 10 domains receive a fresh, isolated setup - new servers and new IPs. We provision infrastructure in these batches to guarantee isolation and performance.

Q: What are domain burn alerts?

They are proactive notifications to slow down sending or replace a domain when reputation is at risk. We track warmup reputation, inbox placement tests, reply rate by domain, bounce rate by domain, and bounce type to catch damage early.

Tired of tanking reply rates and blocked inboxes?
We isolate every 10 domains with built-in burn alerts - whether you
run 30 inboxes or scale with no ceiling.

Yes. Aerosend inboxes work best with a sequencer.
