Visual sequence builder

Build lifecycle flows on a canvas: triggers, delays, conditions that branch on tags, and send steps. Conditions support AND and OR rules, so a single sequence can cover several paths through the same journey.

The SendHeron sequence builder showing a churn-save flow: a tag trigger, a four hour delay, and a condition routing contacts tagged price-sensitive to a save offer email and everyone else to an exit interview email.
A churn-save flow in the builder, captured in a demo workspace: the condition splits price-sensitive cancellations from the rest.

A graph, not a list

A sequence here is a graph rather than a sequence of steps in a row. Branches nest, so a condition inside a branch is just another condition, and one flow can cover several outcomes instead of being duplicated per outcome.

The practical effect is that the person who upgraded on day two and the person who went quiet are handled by the same flow, and there is one thing to change when the copy changes rather than three.

What it is not

It sends email, it waits, and it branches. It does not call webhooks mid-flow or move records in a CRM, and it is not a general workflow automation tool wearing an email badge.

Migrating an existing flow also means rebuilding it, because no two tools model branching the same way. Rebuilding does not have to be manual: once the sequence exists, its whole graph can be written in a single API call.
