About Send Stack
StackMail provides affordable email infrastructure for sales teams, agencies, and professionals running cold outreach. Its platform helps customers set up Google Workspace and Microsoft 365 mailboxes in minutes, with pricing starting at $2.50 per mailbox per month on annual plans. Through a unified dashboard, users can manage domains and inboxes, monitor email health, test configurations, and provision mailboxes in bulk without requiring specialist technical knowledge.
StackMail automates essential DNS configuration, including SPF, DKIM, and DMARC records, and supports both customer-owned domains and domains purchased through the service. Domain isolation keeps each domain in its own panel, while integrations and export options connect mailboxes with major outreach sequencers such as Instantly, Smartlead, Saleshandy, Apollo, Lemlist, and Woodpecker. Teams can add unlimited members and share access to setup workflows. Plans range from a Starter option for freelancers to Growth and Pro tiers for agencies, with volume discounts, priority support, and API access available on select plans. StackMail also offers free email and domain-checking tools, setup guides, and support resources.
