7 Best SuperWave Alternatives for Cold Email in 2026

If you wanted SuperWave's dedicated infrastructure but on flexible terms, InfraForge is self-serve dedicated-IP cold infrastructure at $3/mailbox/mo plus $99 per dedicated IP per month, billed monthly, part of the Salesforge stack. You control it, and there is no annual prepayment.

The $99/IP fee is steep at small scale, real Google mailboxes live in the sibling Primeforge product, and monitoring is a separate product. It is the dedicated-infrastructure alternative for teams that want control and flexibility instead of a managed black box.

Endy Inboxes offers done-for-you private dedicated-IP inboxes from $25/mo for 10 mailboxes (tiers up to $199), roughly $2/mailbox, with monitoring built in and monthly billing. It is the budget done-for-you alternative if SuperWave's $5k felt disproportionate to your volume.

It is a smaller provider and less of an all-in-one, with no bundled lead data or AI engine. If you want managed dedicated inboxes without a five-figure commitment, Endy is a low-risk entry.

Maildoso is SMTP-first cold infrastructure with a floor as low as $0.80/mailbox at scale and a hero rate near $1.80, monthly, with combo plans that add official Google Workspace, three-day placement testing, and self-healing mailboxes, plus a 400k+ mailbox track record and a 4.7 G2 rating (the third-party validation SuperWave lacks).

There is no Microsoft 365, Google is only in Combo bundles, and there is no managed warmup product. It is the value, proven-track-record alternative for high-volume senders.

PrimeForge sells real Google and Microsoft mailboxes self-serve at $4.50/mailbox monthly or $3.50 annually (10-slot minimum), pre-warmed with automated DNS, US IPs, and ESP matching. It is transparent and flexible, with real accounts rather than a possibly-resold managed setup.

It is the best fit if you specifically want real Google/Microsoft accounts on self-serve terms instead of a managed black box.

Zapmail's pre-warmed Google Workspace and Microsoft 365 mailboxes come with ZapShield monitoring, placement testing credits, OAuth setup in about 10 minutes, and transparent tiers ($39/$99/$299 for 10/30/100 mailboxes from a $2.50 floor).

It is a proven, monthly, ready-to-send alternative for teams that want real, pre-warmed accounts they can start sending from quickly.

If you specifically want a done-for-you managed service like SuperWave but with a clearer track record and pricing, ScaledMail builds and runs a Google/Outlook/SMTP package for you, with isolated tenants, volume-based pricing (~$1-$3.50/mailbox), and 2,000+ agency customers. No five-figure annual prepayment, and a far larger, more validated customer base.

There is no self-serve dashboard, reporting is a paid add-on, and there is no free trial. It is the managed alternative when you want done-for-you but with more proof and clearer pricing than SuperWave.
