What is Aerosend?

We’re an inbox provider built for cold emails.

To make cold email successful, you need to send very few emails from 1 domain (60-75 emails/day/domain).

To scale automated outreach, you need multiple domains and inboxes working together.

This helps providers think you are not doing mass outreach, and your emails will land in the inbox.

Aerosend makes the process of creating multiple inboxes and domains easy for you. Aerosend also manages your deliverability, technical setup, warmup, and all the little intricacies to give you the most sophisticated sending infrastructure.

Your alternatives to this process could be setting up multiple domains and inboxes with Google/Outlook, but they will ban you from the platform when they figure out your process.

It is also very expensive, complex, and risky to do this directly.

Who Uses Aerosend?

Cold emailers who want to land in the inbox use Aerosend. Typical clients range from the world’s best lead generation agencies, B2B sales teams, founders, and individual cold emailers.

If you’re sending automated cold emails, you need a solid infrastructure that supports you. Aerosend is just that. We make sure your emails are in the primary folder.

What You Get With Aerosend

You get an end-to-end inbox partner that supports you behind the scenes to make sure your emails land in the inbox.

Here’s what you get with Aerosend inboxes:

• Better deliverability: Your emails go to the inbox, not spam. Clients see an average of 1.2x-1.5x increases in reply rates after switching to Aerosend.
• Complimentary Warm-Up: Free premium warm-up for all our clients. We don’t recommend using traditional warm-up providers, as they are often full of spam traps.
• Domain Burn Alerts: We help you make sure that your reply rate is always high. If your domains get a lot of spam complaints, we ask you to slow down sending or remove those domains

Why Aerosend Inboxes Get More Replies

The domain rotation method, which involves multiple inboxes and domains, is already a proven success.

Aerosend takes the whole concept further with inboxes optimized for cold email. So you get the best of all worlds.

Aerosend uses techniques known to very few people in the email world: Aging fresh IPs, completely isolated servers, premium warm-up, dynamically replacing burnt IPs to be able to achieve a very high inbox rate.

Since most of your emails land in the inbox, you get a much higher reply rate with Aerosend.
