What SendHeron actually does
What SendHeron does: a visual sequence builder, tags and segments, templates, a scoped REST API, EU data residency, and a surface an agent can drive.
Six capabilities, each one running in production today. Nothing on this page is a roadmap item: anything not built yet lives under Integrations and says so.
Visual sequence builder
Triggers, delays, and conditions that branch on tags or contact properties, with AND and OR rules. One flow can cover every path through a journey.
learn moreTags and segments
Tag a contact from your own backend and a sequence starts. Segments are just rules over tags and properties, so there is no separate list to keep in sync.
learn moreTemplates
Reusable email bodies with variable substitution, editable without a deploy and sendable straight from the API.
learn moreREST API
Every object you can touch in the dashboard is reachable over HTTP, with scoped API keys so a key can read contacts without being able to send.
learn moreEU data residency
An EU company, with your contact data stored and processed in the EU. What we can prove is on one page, and so is what we cannot.
learn moreScriptable by agents
Scoped tokens and a plain REST surface, so an agent or a cron job can enroll contacts and send email without a browser session.
