7 Best AeroSend Alternatives for Cold Email in 2026

InfraForge is the closest match to AeroSend's private, isolated-infrastructure model: dedicated-IP email infrastructure at $3/mailbox/mo plus $99 per dedicated IP per month, part of the Salesforge stack. Where AeroSend bundles isolation into 10-domain pods, InfraForge gives you dedicated IPs as an explicit line item and is backed by a more mature ecosystem.

The $99/IP fee makes it expensive at small scale, real Google mailboxes live in the sibling Primeforge product, and monitoring is not as proactive as AeroSend's burn alerts. But if dedicated IPs and a proven ecosystem matter more than bundled burn alerts, it is the like-for-like swap.

Mailbloom (the evolution of Mailscale) takes isolation further than AeroSend's pods: your own dedicated private server with fresh, isolated IPs and up to 200 mailboxes for a flat per-server price. It includes customer screening, 24/7 monitoring, and Smartlead/Instantly integration, with a Trustpilot 4.8.

Per-server pricing is quote-based, dedicated IPs need real volume to stay warm, and it is private SMTP (not Google/Microsoft). But if you want maximum isolation and have the volume to use a private server, it is the heavier-duty alternative to AeroSend's pods.

Maildoso is the value alternative on SMTP economics: a floor as low as $0.80/mailbox at scale and a hero rate near $1.80, with combo plans that add official Google Workspace, three-day placement testing, and self-healing mailboxes that pause and rotate burned accounts, a lighter version of AeroSend's burn-alert idea.

There is no Microsoft 365, Google is only in Combo bundles, and it is shared SMTP rather than per-pod dedicated isolation. But for high-volume senders who want monitoring-style protection at a much lower cost, it undercuts AeroSend with a proven track record (400k+ mailboxes, G2 4.7).

If the real reason you are leaving AeroSend is that you want Google or Microsoft accounts, PrimeForge sells them directly at $4.50/mailbox monthly or $3.50 annually (10-slot minimum), pre-warmed with automated DNS, US IPs, and ESP matching.

It is a higher price than InboxKit, with no per-pod isolation or burn alerts and no standalone monitoring suite. But it is a clean swap if you want mainstream Google/Microsoft inboxes instead of private SMTP.

Zapmail offers pre-warmed Google Workspace and Microsoft 365 mailboxes (12 weeks of warmup done before delivery) with ZapShield reputation protection and placement testing credits. Plans run $39/$99/$299 for 10/30/100 mailboxes from a $2.50/mailbox floor.

There is no Azure, the API is locked to the Pro tier, and placement credits are capped per plan. But if you want real accounts with built-in monitoring and a low entry point, it is a strong pre-warmed alternative.

ScaledMail offers isolated tenants in a fully managed multi-provider package (Google, Outlook, SMTP), built and run for you in 24 to 72 hours. It is the done-for-you alternative if you liked AeroSend's hands-on model but want real Google/Outlook accounts.

There is no self-serve dashboard, reporting is a paid add-on, there is no free trial, and no burn-alert-style monitoring. But it is a managed, real-account alternative when you want isolation without running private SMTP.
