Workflow automation for customer communication

Automate every customer touchpoint, step by step.

Relay lets operations teams design workflows that react to orders, leads and payments — routing each message to the right channel, waiting for replies, and asking a human when it matters.

No credentials needed to try it — messages go to a built-in sandbox outbox until you connect a provider.

Everything you need to run customer workflows

A focused set of building blocks that each do one job well — and work together without glue code.

Rule-based orchestration

Conditions, switches, delays and wait-for-event steps let you build complete journeys without writing code or relying on AI.

Best-channel routing

Reach each customer on WhatsApp, SMS, email, push or voice based on what they have on file and what they opted out of.

Human approvals

Pause a run until a teammate approves it from the inbox, with optional auto-approval under a threshold you set.

Step-by-step run history

Every run records the input, output, chosen path and timing of each step, so you can see exactly what happened.

Versioned publishing

Edit a draft safely while the published version keeps running. Roll back to any earlier version in one click.

AI when you want it

Add AI classification, drafting or a knowledge-grounded agent to a workflow — or leave it out entirely.

From idea to live workflow in four steps

1

Pick a trigger

Start from a webhook, a schedule or a manual run.

2

Add steps

Drag in messaging, logic, data and approval steps, then connect the paths.

3

Test with sample data

Run the draft and inspect every step before anything reaches a customer.

4

Publish

Activate the workflow. Webhooks and schedules start running the published version.
