Helo is an email API and SMTP service for sending transactional email, such as password resets, receipts and notifications, and marketing email from applications. Its co-founder presented it on Hacker News on 1 October 2026. The team says most of its members worked together for years at the email provider Postmark; its About page lists people in the United States, Canada, Germany and Japan and says the company is bootstrapped and intends to stay independent. Helo offers one plan: 1,000 free emails for testing, then a $5 monthly platform fee plus $0.00035 per email, with unlimited users, unlimited sending domains, multi-tenant sending, detailed analytics and unlimited webhooks. Its pricing page includes a calculator comparing the bill with other email services at different volumes.
