Zapmail

Overview

Zapmail is an email infrastructure platform designed for high-volume outreach and cold email campaigns. It provides affordable, US-hosted Google Workspace and Microsoft 365 business mailboxes that are fully automated—covering mailbox creation, DNS configuration, and integration with popular outreach tools. With over 1 million mailboxes set up and more than 330,000 domains managed, Zapmail is built to help teams achieve industry-leading inbox placement without the overhead of manual setup or extended warmup periods.

The platform differentiates itself by offering pre-warmed, aged domains that are ready for sending from day one. Each domain is assigned to its own dedicated workspace, ensuring workspace-level isolation and stronger sender reputation. Zapmail automatically sets up SPF, DKIM, DMARC, and custom tracking domains, while leveraging US/EU IP addresses to boost deliverability. The streamlined workflow lets users buy or connect their own domains, auto-generate mailbox names, and export credentials to platforms like Instantly, Smartlead, ReachInbox, Reply, and Lemlist via OAuth—without dealing with SMTP relays or manual app passwords.

For teams that need programmatic control, Zapmail offers a headless API designed for SaaS and AI SDR platforms. This API covers mailbox provisioning, domain management, and deliverability insights, enabling developers to integrate email infrastructure directly into their own products. Additionally, AI-powered workflow tools such as Instant Domain Genie, Smart Mailbox Namer, and Persona Snapshots help users quickly generate brand-ready domain suggestions, professional mailbox handles, and profile images that align with their brand identity.

Zapmail's flexible pricing plans start at $2.50 per mailbox, with monthly, quarterly, and yearly billing options. Plans include varying numbers of Google mailboxes, deliverability test credits, AI Insight credits, and API access on higher tiers. Trusted by more than 50,000 businesses worldwide, Zapmail positions itself as a complete alternative to traditional SMTP mailboxes and legacy Google/Microsoft resellers, offering fully automated, deliverability-focused email infrastructure that scales with modern outreach teams.
