Frequently Asked Questions

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

At Aerosend, we conducted a deep dive into everything that can affect or remotely influence deliverability. We have combined the best of all aspects to provide you with an infrastructure that has everything.

Isolated Infrastructure, Aged- Premium IPs, Dedicated Servers, Dynamic IP Rotation, and Domain Burn Alerts are some of our secrets to high deliverability.

Q. How does Aerosend adapt to cold email changes?

We continuously monitor and test the market for any changes. Our dedicated deliverability engineers can identify changes in deliverability before they impact the broader market.

We also have an engine that constantly monitors and adapts your sending setup:

Our dynamic engine monitors and adapts your sending setup to keep your emails landing in the inbox.

IP Health Monitoring

If we detect a drop in IP performance, we proactively rotate your IP before it affects your deliverability.

Warmup Pool Monitoring

We constantly monitor six warmup pools for ESP Mix, Domain Age, and Bounce rates to ensure your infrastructure is not affected.

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

The biggest difference is a private infrastructure supports you to send cold emails whereas Google/Outlook penalize you.

However, running a private infrastructure is extremely complex, and very few companies in the world can do it correctly.

Google/Outlook will ban you and send you to SPAM if you use their inboxes. Aerosend faces no bans, and you get better deliverability.

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

Yes. Aerosend inboxes work best with a sequencer.

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

We create a new infrastructure for every 10 domains: new servers and new IPs. Hence, orders are made in batches of 10-domain slots.

Q. What are domain burn alerts?

Domain burn alerts are notifications you will get to either slow down sending or replace your domain.

We monitor 5 metrics for your domains – Warmup Reputation, Inbox placement tests, Reply Rate by Domain, Bounce Rate by Domain, Bounce Type

Our proprietary algorithm detects damage to the domain reputation and sends you an alert anytime it is affected.
