Zapmail

Zapmail is a cold email infrastructure provider that offers pre-warmed Google Workspace and Microsoft 365 mailboxes hosted on US IPs, built for teams that want to start sending from day one without waiting weeks for warmup.

It handles everything from automated DNS setup to mailbox creation and direct integration with your outreach tool, all in under 5 minutes on average.

Trusted by 50,000+ businesses worldwide, Zapmail is built for freelancers, agencies, and teams running cold email at scale.

What Is Zapmail?

Zapmail is a cold email inbox provider, not an outreach sequencer.

It sits at the infrastructure layer of your cold email stack, providing the mailboxes and domains you send from, not the tool you use to write and schedule campaigns.

What sets Zapmail apart is its workspace-level isolation model, where each workspace gets its own dedicated domain with full admin access, significantly reducing ban risk and improving deliverability.

It also comes with AI-powered tools like an Instant Domain Genie, Smart Mailbox Namer, and Persona Snapshot generator, making it one of the more complete inbox infrastructure tools on the market.

Zapmail Pricing (2026)

Zapmail offers three workspace plans billed monthly.

The Starter plan is priced at $39/month and includes 10 Google mailboxes with additional mailboxes at $3.50 each, making it a good fit for freelancers and solo operators.

The Growth plan, their most popular option, is priced at $99/month and includes 30 mailboxes with additional ones at $3.25 each, suited for mid-size agencies.

The Pro plan is priced at $299/month and includes 100 mailboxes at $3.00 each, with priority support and API access included.

Quarterly and yearly billing options are also available. Yearly plans offer two months free, bringing the per inbox cost down to $2.50 on annual billing. Microsoft 365 mailboxes and pre-warmed mailboxes are also available as separate purchasing options.

Zapmail as a Cold Email Inbox Provider

Zapmail is purpose-built as a cold email inbox provider rather than an all-in-one outreach platform.

This means you pair it with a separate sequencing tool like Instantly, Smartlead, or Woodpecker to run actual campaigns. Zapmail handles the infrastructure layer: domains, mailboxes, DNS authentication, and warmup.

Zapmail Email Warmup

Zapmail offers pre-warmed mailboxes that are ready to plug into campaigns immediately.

This eliminates the typical waiting period of several weeks that is usually required before sending cold emails at volume.

The warmup approach uses workspace-level domain isolation combined with US-hosted IPs to build sender reputation before your first send.

Each workspace gets its own dedicated domain with admin access, which significantly reduces the risk of one compromised inbox affecting others.

Zapmail Email Deliverability

Zapmail approaches deliverability through infrastructure rather than sending behavior. The core mechanisms are:

• Automated SPF, DKIM, and DMARC setup on every domain
• One domain per workspace isolation to contain reputation damage
• US and EU hosted IPs for inbox placement
• Pre-warmed accounts that arrive with established sender history
• Custom tracking domain support to avoid shared tracking domain blacklists

These features address the most common infrastructure-level reasons cold emails land in spam, without requiring technical knowledge from the user.

Zapmail API

Zapmail provides a headless email infrastructure API that allows developers and AI SDR tools to handle everything programmatically, from mailbox provisioning to deliverability insights. API access is included in the Pro plan at $299/month.

This makes Zapmail a practical choice for teams building AI SDR systems or SaaS products that need to provision and manage mailboxes at scale without manual intervention. The API covers mailbox creation, DNS management, and deliverability monitoring.
