What SendHeron actually does
What SendHeron does: a visual sequence builder, tags and segments, templates, transactional and marketing mail on one suppression list, a scoped REST API, EU data residency, and a surface an agent can drive.
7 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
Build an email from blocks without writing HTML, or write the HTML yourself. The server compiles both, so the preview you approve is the email that arrives.
learn moreTransactional and marketing
Receipts and campaigns from one account, on one sending reputation and one suppression list. A bounce blocks every stream. An unsubscribe blocks marketing only, and only for the brand it was given to.
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 in Germany, and a published sub-processor list. 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.

Every one of these is live today
Nothing on this page is a roadmap item. Start a trial and use all of it on real sending.
7-day free trial. Pick a plan, add a card, cancel before the trial ends and you won't be charged. 1,000 contacts and 5,000 sends during the trial.
