Inboxes built for cold email.
They rent you the inboxes, then it's on you when you land in spam.
On their ownThe only provider on the hook for whether you actually land.
On the hookThe same question, decided row by row. One column owns whether you land.
Google is widely considered the gold standard for deliverability. But in cold email, a lot of other factors come into play. Where the inboxes are purchased from, how they're isolated at scale, how they're warmed up, and how you use the inboxes themselves all decide whether you actually land in the inbox. On Warm Inboxes, deliverability becomes your job. With Aerosend, it is ours.
Official Google Workspace reseller pricing runs $6+ per inbox. Inboxes sold well below that are typically resold through cheaper, third-party channels.
When you buy from a reseller, they do not own the infrastructure. When Google changes their rules or domains start to burn, there's nothing they can do.
When a domain starts to burn, nothing flags it, so the problem can spread for days before you notice. By the time a client asks why their replies dried up, the damage is done.
We watch every domain across 6 metrics - reply rate, bounce rate, bounce type, blacklists, inbox placement test and warmup reputation. We actively tell you before a domain is burnt.
We run your warmup and take responsibility of your deliverability. You're not getting inboxes. You're getting a team of experts whose job is to help you send emails that will land in inboxes.
Warmup is sold as a separate, higher-priced plan tier rather than bundled, and there is no inbox-deliverability monitoring and no domain-protection product at all. Aerosend includes warmup, monitoring, and domain protection in one price, then takes 30% off your first 3 months. You pay less, and nothing's hidden.
The inbox price is the start of the bill, not the end of it.
Built by operators who lived your problem. Namit Jindal ran a lead-gen agency sending up to 1.5M cold emails a month and hated every provider he used: shared IPs, zero monitoring, no burn detection. So he built the infrastructure he wished existed, with co-founder Prabhu Rengaswamy, a 20-year infrastructure architect. One's a Smartlead Hall of Famer in the top 1% of cold emailers. The other engineered the isolation and monitoring stack. Operators, not outsiders.
“Aerosend just works.”
Now books 2-3 meetings a day.
One choice after the full field.
Nothing changed but the inboxes.
“A vendor that's on your side.”
Placement that holds at scale.
Volume of intent, every week.
Region-specific, still landing.
Individual results reported by named customers; methodology and dates on file (as of June 2026).
We will be straight about who each one is for. If one of these reads like you, you already know which way the scale points.
All three are real reasons to use Warm Inboxes. We would rather you keep what works than change for the sake of it.
We built Aerosend to be a more reliable way to land cold email. Test us against anyone you're considering.
