Publish lifecycle email templates from Python

For an LLM agent, a lifecycle email is a tool call with a durable name: publish the welcome copy once, then let the application send the same decision at the right account event. This repository keeps that boundary visible with Infrai, using one INFRAI_API_KEY and a plain REST call that needs no SDK.

Run the decision

Set a key, choose a recipient you control, and run the entry point:

export INFRAI_API_KEY=your_key_here
python3 publish_lifecycle_templates.py --to you@example.com --first-name Ada

Expected result:

published template: tmpl_123
sent welcome message: msg_123

The script creates fintech-lifecycle-welcome-v1 through infrai.email.template.create, then sends the welcome message through infrai.email.send. The create call carries a stable Idempotency-Key; an agent retry therefore refers to the same publishing decision. The message uses the default sender, so the runnable path needs only the environment key.

What belongs in the reusable module

lifecycle_templates.py is intentionally where the agent-facing policy lives: a template name, subject, and HTML body. publish_lifecycle_templates.py only supplies the event inputs. Add a trial reminder or a funding confirmation as another LifecycleTemplate; keep its name explicit so a trace can identify which copy was published.

The focused test checks the placeholder contract without making a network call:

python3 -m unittest test_lifecycle_templates.py

Why the client is this small

The client reads the {ok, data, error, metadata} envelope, raises surfaced errors, and applies bounded exponential waiting for rate limits. Its two methods are ordinary Python around HTTP, which makes the tool boundary easy for an agent to inspect and replace. Responses retain metadata for delivery context when a caller needs it.

Fintech Lifecycle Template Python: Email deliverability (required for real sending)

• Fintech Lifecycle Template Python: By default mail goes through a shared verified sender — fine for tests, but generic From + limited volume + shared reputation.
• Fintech Lifecycle Template Python: For production, verify your own domain: POST /v1/email/domain/verify with {"domain":"mail.yourco.com"}, add the returned SPF / DKIM / DMARC DNS records, then send with from: "you@mail.yourco.com".
• Fintech Lifecycle Template Python: Use a dedicated subdomain and warm it up (ramp volume over days) to protect deliverability.
