We own the deliverability.
Getting to the inbox takes constant work: warming up every domain, keeping it landing, and adjusting as inboxes age. We run all of it for you, continuously.
Cold email inboxes made to help you land in the inbox. You just send emails.
They hand you the infrastructure, 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.
Good infrastructure matters, but on its own it will not get you to the inbox. Landing cold email is complex: every domain has to be warmed up, watched for burn, and kept isolated so one bad domain cannot drag down the rest. That takes a team managing it every day, not just servers you are handed and left to run. On Skysenders, that team is you. With Aerosend, that team is us, so you land in the inbox and get more replies.
Getting to the inbox takes constant work: warming up every domain, keeping it landing, and adjusting as inboxes age. We run all of it for you, continuously.
Domains burn, and if no one catches it fast, your replies dry up before you notice. We watch every domain across 6 metrics, around the clock, and catch a burn before it spreads.
A single burn that spreads across a packed IP can take a whole setup down at once, which is why catching it early matters.
We isolate every 10 domains on their own IP, so a single burn stays contained instead of taking your whole setup down. On Skysenders, all of this is your job. With Aerosend, it's a team whose only job is keeping you in the inbox.
Dedicated infrastructure gets priced every which way: per mailbox, per email, per server, usually with a floor and a multi-month commitment. The only fair comparison is what it costs to send the same volume. Here's 600 emails a day, everything in, with 40% off your first 3 months.
The floor 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 Skysenders. 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.
Run both side by side, same copy, same list. If your reply rate isn't higher with us, you get your money back.
The five things people ask right before they switch. The short answer to each is on the right. Open any row for the rest.
Dedicated beats a shared pool, no question. But most dedicated providers still pack dozens of inboxes onto each IP, and you rarely know where those IPs have been. We isolate every 10 domains on their own aged, never-used IP and watch them every day. Dedicated, done right.
