Hypertide
Hypertide is an automated cold email infrastructure platform built to help teams scale outreach across Google, Microsoft, and Entra with high-deliverability inboxes connected to their favorite sending tools in hours. It simplifies the complexity of email infrastructure so users can focus on scaling outreach instead of manually configuring domains, inboxes, DNS records, and provider-specific workflows. Hypertide works with Google inboxes, Microsoft, and Entra communication APIs, giving outbound teams a centralized way to manage infrastructure across multiple platforms from one app. Its automated setup process configures domains, users, inboxes, and technical authentication such as SPF, DKIM, and DMARC, helping reduce misconfigurations and delays that often come from manual setup. Each order is isolated with tenant separation, ensuring dedicated domains, IPs, and users for stronger deliverability and cleaner reputation management.

EmailPal
EmailPal is cold email infrastructure built for outbound teams and agencies. It handles everything between buying a domain and delivering an email. You can register domains or bring your own, and EmailPal sets up SPF, dual-key DKIM, DMARC and MX records automatically. Mailboxes are provisioned in bulk with SMTP and IMAP credentials ready to use. Built-in warming sends to real Gmail, Yahoo and AOL accounts, and a mailbox is only marked campaign-ready once measured inbox placement proves it. You can also lease pre-warmed inboxes on aged domains and start sending the same day. Deliverability is managed automatically, with hourly reputation scoring per provider and automatic quarantine and recovery of problem addresses.
