Heyo is cold email software built to help sales and outbound teams scale outreach affordably. Connect unlimited sending accounts with no per-seat fees, and let Heyo's automatic peer-to-peer warmup protect your sender reputation from day one. Built specifically for Microsoft Exchange, Heyo lets you spin up mailboxes for as little as $0.34–$0.44/month — a fraction of the $5–$7/month typical of Google Workspace or Outlook — so costs don't balloon as you scale to hundreds of accounts.
Import and segment leads with CSV uploads and custom fields, then build multi-step campaigns with conditional logic, spintax, A/B testing, and automated daily ramp-up limits to keep domains healthy. All replies land in a single Global Unibox, so no lead gets buried across dozens of inboxes. Built-in compliance tools include automatic unsubscribe links, tracking subdomains, and a global Do Not Contact list to protect your brand and keep campaigns CAN-SPAM and GDPR aligned.
Plans start at $39/month, with agency whitelabeling and a developer REST API available on higher tiers.
