AeroSend Pricing 2026: Per-Inbox Cost, What's Included & Real Math

AeroSend prices per inbox: $4/inbox/month for your first 150 inboxes, then $2/inbox/month for every inbox after 150. Orders have a 30-inbox minimum and are sold in batches of 30 ($120 per batch for the first 150, $60 per batch above 150). Each batch of 30 is an isolated pod — 10 domains, 3 mailboxes per domain, on dedicated aged IPs — handling roughly 12,000–15,000 emails/month. Every order includes the full managed stack at no extra cost: managed (ESP-tailored) warmup, biweekly inbox placement tests, 5-metric burn detection, 24/7 monitoring, proactive IP rotation, free domain replacement, and a deliverability guarantee. Domains are bring-your-own (~$10–12/year each). It's private SMTP infrastructure (aged IPs), not Google/Microsoft accounts, with a ~3-week ramp to full sending. The standout: warmup and monitoring are bundled into the per-inbox price rather than sold as add-ons, and the blended rate falls toward $2/inbox as you scale.

AeroSend's model is per-inbox and all-inclusive:

• Two-band per-inbox pricing. Your first 150 inboxes are $4/inbox/month; every inbox after 150 is $2/inbox/month. The discount applies automatically as you cross 150 — there are no named tiers to choose.
• Sold in batches of 30, 30-inbox minimum. Capacity is purchased in 30-inbox blocks ($120/batch below 150, $60/batch above 150). Each block of 30 is an isolated pod of 10 domains (3 mailboxes/domain) on its own aged, pre-warmed dedicated IPs — fully isolated from other customers.
• Everything is included. Warmup, biweekly inbox placement tests, burn detection, 24/7 monitoring, IP rotation, and reporting come with every order — "no add-ons, no hidden fees."
• Private SMTP, not Google/Microsoft. AeroSend is purpose-built SMTP infrastructure with aged IPs; you connect the mailboxes to your sequencer (Smartlead, Instantly, lemlist, etc.) via CSV/IMAP/SMTP.

There are no contracts, you can cancel anytime, and AeroSend offers a deliverability guarantee (it will outperform your current infrastructure).

Example configurations (exactly as AeroSend states them):

Each batch of 30 inboxes = 10 domains (3 mailboxes/domain). Rates are from the AeroSend pricing page. The more you scale past 150, the closer your blended rate gets to $2/inbox.

Every AeroSend order is a complete, isolated, managed sending environment:

• Dedicated, aged, pre-warmed IPs — 100% isolated, your reputation alone, with each batch of 10 domains on its own pod.
• 3 mailboxes per domain, auto SPF/DKIM/DMARC.
• Managed warmup, tailored to your ESP (Smartlead/Instantly/lemlist behave differently).
• Biweekly inbox placement tests across Gmail, Outlook, Yahoo.
• 5-metric burn detection with domain health scoring (0–100) to catch problems early.
• 24/7 monitoring + intervention, proactive IP rotation, and monthly performance reports.
• Free domain replacement (you buy the ~$10–12 domain; AeroSend re-provisions free).
• Founder-led support and a client portal with full visibility.

The notable part: warmup and monitoring are bundled — you're not paying separately for a warmup tool or a monitoring suite.

AeroSend bundles most things, so the real cost is close to the inbox price plus domains:

• Starter (30 inboxes): $120/month + 10 domains (~$10/month amortized at ~$12/year) = ~$130/month for 30 mailboxes (~$4.33/mailbox all-in).
• Plus a sequencer: AeroSend is infrastructure only; budget ~$99/month for Smartlead or Instantly.
• A realistic full stack: sequencer (~$99) + domains (~$10) + AeroSend (30 inboxes, $120) + lead data (~$30) + AI tools (~$10) = ~$269/month for ~12–15k emails/month, with infrastructure roughly 45% of the total.
• At scale: 300 inboxes = $900/month (~$3.00/inbox); 900 inboxes = $2,100/month (~$2.33/inbox).

Because warmup and monitoring are included, there are genuinely few surprise line items — the main extras are domains and your sequencer.

Five things to weigh:

1. 1It's private SMTP, not Google/Microsoft. AeroSend uses aged dedicated IPs on its own servers. Excellent isolation and control, but a different deliverability profile than official Google/Microsoft accounts, and some audiences/filters favor established Google/Microsoft domains.
2. 2~3-week ramp to full capacity. Domain provisioning is 24–48h, but managed warmup runs about 21 days — so plan ~3 weeks before full sending.
3. 3Bought in 30-inbox blocks. You buy capacity in 30-mailbox batches; smaller needs still buy a full 30-inbox block (the minimum).
4. 4Conservative send limits. Roughly 20–25 cold emails/mailbox/day — generous vs some, but still means more mailboxes for high volume.
5. 5Domains are bring-your-own. ~$10–12/domain/year on top of the inbox fee (though replacement after a burn is free).

The honest positioning: AeroSend is one of the more complete managed private-infrastructure products — bundling ESP-tailored warmup, biweekly placement tests, 5-metric burn detection, and 24/7 monitoring into the per-inbox price is genuinely strong value, and the isolation (dedicated aged IPs per 10-domain pod) plus deliverability guarantee back it up. The trade-off is that it's private SMTP with aged IPs rather than official Google/Microsoft accounts, and there's a ~3-week ramp. InboxKit takes the official-account route: Google Workspace, Microsoft 365, and Azure mailboxes at $2.50–$3.50/mailbox with much faster setup (10 minutes to 2 hours), US-IP infrastructure, per-domain admin panels, and a full API. The key difference in what's bundled: AeroSend includes warmup and monitoring in its rate, while InboxKit prices warmup ($3/mailbox) and InfraGuard monitoring as add-ons — so compare AeroSend's $2–$4 all-in (by volume) against InboxKit's base rate plus the add-ons you want, weighed against InboxKit's official accounts, Azure option, and faster ramp.

AeroSend makes sense for agencies and high-volume senders who want a fully-managed private SMTP setup with monitoring and warmup included — and who value isolation (dedicated aged IPs) and a deliverability guarantee over running official Google/Microsoft accounts. If you want one all-inclusive per-inbox price that covers warmup, burn detection, and 24/7 monitoring, AeroSend's bundle is hard to assemble more cheaply piece by piece — and because the rate drops to $2/inbox above 150, it gets more attractive the more you scale. It's especially strong for teams that have been burned on shared infrastructure and want hands-off reliability.

AeroSend is harder to justify when:

• You want official Google/Microsoft accounts. AeroSend is private SMTP with aged IPs. For official Google Workspace, Microsoft 365, or Azure mailboxes, see InboxKit.
• You need to send fast. The ~3-week managed-warmup ramp delays full sending; official-account providers can be live much sooner.
• You only need a handful of mailboxes. The 30-inbox minimum means very small needs still buy a full block.
• You want à la carte control. AeroSend bundles everything; if you'd rather pay only for the mailboxes and add warmup/monitoring selectively, a per-mailbox provider with add-ons fits better.

AeroSend is a strong, all-inclusive managed private-infrastructure product. Per-inbox pricing ($4/inbox for the first 150, then $2/inbox above 150, sold in batches of 30) is fair given everything bundled — aged dedicated IPs, ESP-tailored warmup, biweekly placement tests, 5-metric burn detection, and 24/7 monitoring with no add-ons. For agencies that want isolation, hands-off reliability, and a deliverability guarantee, it's a compelling package, and the blended rate falling toward $2/inbox at scale makes the high-volume math genuinely good.

The trade-offs are the infrastructure type and ramp: these are private SMTP aged-IP mailboxes rather than official Google/Microsoft accounts, and full sending takes ~3 weeks. If you'd prefer official Google, Microsoft 365, and Azure mailboxes with faster setup, US IPs, per-domain admin panels, and a full API — choosing warmup and InfraGuard monitoring as add-ons rather than a fixed bundle — see how InboxKit compares.
