Overview
Zapmail, from Outbox Labs, sells Google Workspace and Microsoft 365 mailboxes built for outbound. Starter is $39 per month for 10 Google mailboxes, with extra mailboxes at $3.50 each. Growth is $99 per month for 30 mailboxes at $3.25 extra. Pro is $299 per month for 100 mailboxes at $3.00 extra, and Pro includes API access. Every plan uses US/EU IP accounts, automated SPF, DKIM, and DMARC, and one domain per workspace. Pre-warmed mailboxes are meant to send from day one.
Agencies pick Zapmail to skip manual DNS and app-password setup. Native OAuth export names Instantly, Smartlead, ReachInbox, Reply, and Lemlist. AI tools include Instant Domain Genie, Smart Mailbox Namer, Persona Snapshots, and monthly AI Insights credits. REST docs sit at docs.zapmail.ai, but the API is a Pro feature. There is no published free trial. The homepage also says mailboxes start at $2.50, which is below the $39 Starter pack.
