Gmail API bulk email sending

Backend & APIs

What this skill does

# Email Send Bulk

> Bulk email sending via Gmail API from Google Sheets

## When to use

- "send email"
- "write an email"
- "email campaign"
- When `preferred_channel = Email` in data

## IMPORTANT: Confirmation rule

**ALWAYS show the email text (To, Subject, Body) and ask for user confirmation BEFORE sending.**
Never send an email without an explicit "yes" / "send it" from the user.

## Dependencies

- Python 3.12+ (venv: `$GOOGLE_TOOLS_PATH/.venv/bin/python3`)
- google-api-python-client, google-auth-oauthlib
- Google OAuth token with Gmail scope

## Paths

| What | Path |
|------|------|
| Script | `$GOOGLE_TOOLS_PATH/send_emails.py` |
| Token | `$GOOGLE_TOOLS_PATH/token.json` |
| Credentials | `$GOOGLE_TOOLS_PATH/credentials.json` |

## Spreadsheet Config

- **ID:** `YOUR_SPREADSHEET_ID`
- **Sheet:** `Form Responses (1)`

| Column | Index | Purpose |
|--------|-------|---------|
| B | 1 | Name |
| C | 2 | Email |
| T | 19 | Email Status |
| U | 20 | Email text |

## How to run

```bash
cd $GOOGLE_TOOLS_PATH
.venv/bin/python3 send_emails.py 5      # send 5 emails
.venv/bin/python3 send_emails.py 10     # send 10 emails
.venv/bin/python3 send_emails.py        # default 5
```

## How it works

1. Reads Google Sheet
2. Filters: `status != Sent` AND `email` is not empty AND `text` is not empty
3. Composes email from `Your Name <[email protected]>`
4. Sends via Gmail API
5. Updates status in column T
6. **1 sec delay** between emails

## Subject

Hardcoded in script:
```
Data labeling training from YourCompany Inc.
```

To change -- edit `SUBJECT` in the script.

## Statuses (column T)

- `Sent` -- success
- `Error: ...` -- error details

## Sender

```
From: Your Name <[email protected]>
```

## Limits

- Gmail limit: ~500 emails/day
- ~2000 emails/day for Google Workspace
- 1 sec delay (can be reduced)

## How to prepare email text

Text is taken from column U. Can be prepared via:

```python
# $GOOGLE_TOOLS_PATH/prepare_emails.py
# Generates personalized text for each recipient
```

## Troubleshooting

| Problem | Solution |
|---------|----------|
| 401 Unauthorized | Refresh token: `google-auth` |
| Daily limit exceeded | Wait 24 hours |
| Invalid email | Check format in spreadsheet |

- `google-auth` -- if authorization issues
- `update-lead` -- update status after campaign

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
