How much does zuzu.codes cost?

The starter track is free — read all lessons and practice for free. Full access to every track (current and future) is $14.99/month. Cancel anytime.

How long does each track take?

Each track is designed as a 30-day challenge — one lesson per day, about 15 minutes each. Go at your own pace, but the structure is built around daily consistency.

What's the lesson format?

Each lesson is a student-teacher dialogue with code examples, followed by a hands-on code challenge in an in-browser editor. You read, you understand, then you write real code.

Do I need prior coding experience?

Our beginner track starts from absolute zero — no prior experience needed. Advanced tracks build on earlier ones, and the platform tells you exactly where to start.

How is zuzu.codes different from freeCodeCamp or Codecademy?

zuzu.codes uses a structured 30-day track format with dialogue-based teaching, an in-browser code editor, and gamification (XP, streaks, progress tracking). The format builds genuine understanding through daily practice.

Send an Email from Python — Safe-to-Self Pattern — Automation For Entrepreneurs

Day 7 · ~12 min●

Your draft_email creates a draft for review. When you're confident the workflow is correct and want Python to send automatically — how do you do it safely?

After draft_email I know the shape is right. But sending automatically to a real investor without a review step feels risky. What if there's a bug in the metrics?

That instinct is correct. The safe-to-self pattern: always set to to your own email address during development and initial testing. The investor gets a CC'd version only when you've verified the output is right. GMAIL_SEND_EMAIL delivers immediately — there's no undo:

python

result = toolset.execute_action(
    Action.GMAIL_SEND_EMAIL,
    {"to": to, "subject": subject, "body": body}
)
print(f"Sent to {to}: {result.get('id', 'no id')}")

So in every test I run here, to should be my own email? Even if the function signature accepts any address?

Exactly. The problem statement always uses a self-address. Real recipients come after three successful test runs. GMAIL_SEND_EMAIL is irreversible — a wrong subject line or a garbled MRR number lands in a real inbox. Draft first, test on self, then point at real recipients. Here's the full function:

python

def send_email(to: str, subject: str, body: str) -> dict:
    result = toolset.execute_action(
        Action.GMAIL_SEND_EMAIL,
        {"to": to, "subject": subject, "body": body}
    )
    print(f"Sent to {to}")
    return result

Three lessons: count, draft, send. The whole Gmail workflow is now Python. My Monday investor update runs itself from here.

Your Monday morning just reclaimed an hour. Every week, forever.

I went from 'scanning my inbox manually' to 'Python sends the formatted update automatically' in five lessons. That's founder leverage.

Add confirmation logging to every send: print(f'Sent to {to}'). Automated sends without logs are silent failures waiting to happen. You need to know which emails went out and when.

Sending Email with Composio

GMAIL_SEND_EMAIL delivers immediately — no confirmation dialog. For investor updates, the safe-to-self pattern prevents accidental sends before your weekly pipeline output is verified and trusted.

python

toolset.execute_action(
    Action.GMAIL_SEND_EMAIL,
    {"to": "self@me.com", "subject": "...", "body": "..."}
)

Safe-to-self pattern

Develop with to = your_own_email
Verify output in your inbox
Switch to real recipient only after 3 clean test runs

Pitfall

GMAIL_SEND_EMAIL is irreversible. No unsend. Add logging to every send call.
