Aerosend review (2026): pricing, pros and cons, alternatives

What Aerosend is

Aerosend is a managed cold email infrastructure provider run by Aerosend Ventures Private Limited in India. It was founded in 2024 by Namit Jindal, who had run a lead generation agency sending 500,000 to 1.5 million cold emails a month, and Prabhu Rengaswamy, and launched in 2025 after what the about page describes as a year of testing. The pitch is that it takes responsibility for your deliverability rather than selling you accounts: private SMTP inboxes on dedicated servers and aged IPs, with warmup, inbox placement tests, monitoring and domain replacement all included, and the founder on the other end of support. The site says more than 150 agencies use it, which is the company’s own figure.

Aerosend pricing

There are no plans, just a price per inbox per month: $4 each for the first 150 inboxes and $2 each for every inbox after that. The minimum is 30 inboxes, sold in batches of 30, so the entry price is $120 a month, and 300 inboxes cost $900. The batches exist because Aerosend builds a fresh set of servers and IPs for every 10 domains and puts 3 inboxes on each. The calculator on the pricing page puts the sending capacity of 30 inboxes at 12,000 emails a month, which is 400 per inbox, and the terms refuse refunds to anyone who sends more than 40 a day per mailbox, so that is the working ceiling. Domains are yours either way: bring your own, or Aerosend buys them for $12 a year and renews them automatically up to $15 while your subscription is active. A code on the pricing page gives the first 30 inboxes free for a month, and the site says it will beat any price above 300 inboxes.

The performance guarantee is unusual enough to spell out. You run 30 Aerosend inboxes beside your current setup with the same copy and the same list, through 3 weeks of warmup and 5 weeks of sending, and if the Aerosend reply rate comes in lower, Aerosend refunds two months of fees on 30 inboxes. The terms attach conditions: every recipient verified, catch-alls included, plain-text emails without HTML, pixels or images, and a like-for-like test. Outside the guarantee, the terms run a no-refund policy with one exception for service-quality issues caused by Aerosend in the first 14 days. Domain costs are never refunded, refunds are processed within 3 business days after a dispute is resolved, the mailboxes must stay active while that happens, and refunds are refused for spam violations, warmup under 14 days, missing unsubscribe text or mailing free email domains. Subscriptions renew monthly unless cancelled before the renewal date, with no contract. The whole agreement sits under Indian law and the courts of New Delhi.

Setup and integrations

You bring the list, the copy and the sequencer, and Aerosend does the rest: connect or buy domains, add names for the inboxes, and the team creates them, writes SPF, DKIM and DMARC, and starts the warmup. The pricing page says inboxes are provisioned inside two days, although another line on the same page says live in 24 hours, and the warmup runs for 21 days before you send on day 22. The homepage names Warmupinbox as a warmup provider. Once warmed, the inboxes connect to any sequencer, and a free Domain Burn Alerts tool checks domains already running in Smartlead or Instantly. If you already have inboxes elsewhere, Aerosend suggests building new domains beside the old setup and winding the old one down after warmup, which is the same motion as the guarantee test.

Deliverability

This is the whole product. Every 10 domains get their own servers and IPs, so another customer’s mistakes stay on their infrastructure, and the IPs are aged rather than fresh. Monitoring runs around the clock across five metrics, warmup reputation, inbox placement tests, reply rate by domain, bounce rate by domain and bounce type, and the burn alerts tell you to slow down or replace a domain before replies fall. Placement tests run every two weeks, IPs are rotated when their performance drops, and burned domains are replaced free. The trade is that these are private SMTP inboxes, not Google or Microsoft tenants, and the terms require you to stay under 40 emails a day per mailbox, warm for at least 14 days, include unsubscribe text and keep off free email domains. The reply-rate and placement figures on the site are testimonials the company chose, so treat them as claims rather than benchmarks.

Who Aerosend is for, and who should look elsewhere

Aerosend suits agencies and teams running 30 or more cold email inboxes who want someone else to own warmup, monitoring and replacements, and who are comfortable sending from private SMTP rather than Google or Microsoft accounts. It is a poor fit for teams below 30 inboxes, for anyone who needs official Google or Microsoft accounts, or for anyone who needs to send this week rather than in three. Hypertide and Infraforge sell private infrastructure on a self-serve model with faster starts, and Mailreef sells dedicated IPs by the server. The inbox provider comparison scores all of them.

Where PureMail is cheaper, and where Aerosend wins

PureMail’s Google Workspace and Microsoft 365 inboxes, configured and connected by a team cost $3.30 each for 10, $3.10 for 30 to 100 and $2.90 for 101 or more, billed monthly, with a 10-inbox minimum and setup in about 4 hours. Against Aerosend that is $93 against $120 for 30 inboxes, $310 against $400 for 100, and $870 against $900 for 300. Aerosend’s $2 rate past 150 closes the gap as you grow, and from about 334 inboxes it becomes the cheaper option. Full details are on the pricing page.

Aerosend wins on the managed layer. PureMail does not bundle warmup or placement tests; Aerosend includes a 21-day warmup, biweekly placement tests, monitoring with burn alerts, free domain replacement and a reply-rate guarantee, and it isolates every 10 domains on their own servers. For an agency at scale that wants private SMTP with someone accountable for deliverability, that is a real offer. For a team that wants official Google or Microsoft accounts, a smaller minimum, and sending within the day, PureMail is the simpler and cheaper route. The table below puts the two side by side.
