## Why bit-by-mail

Most bulk email tools are SaaS platforms, where you upload your recipient list to someone else's server and pay a monthly fee for the privilege. bit-by-mail flips that: it's a lightweight local app that runs on your machine and sends through your own email provider. Your data stays yours, and there's nothing to pay for.

## Features

- **Local and private** — runs entirely on your machine; nothing is uploaded anywhere
- **Bring your own SMTP** — works with Gmail, Outlook, Yahoo, or a custom domain; supports multiple accounts with a default sender fallback
- **Dynamic personalization** — one template, personalized per recipient using variables from your CSV (`{{FirstName}}`, `{{InvoiceAmount}}`, etc.)
- **Personalized attachments** — send different files to different recipients in the same campaign (certificates, invoices, reports)
- **Rich text or raw HTML** — use the WYSIWYG editor, or drop into a Monaco-based HTML editor for full control
- **Preflight checks** — simulates the send beforehand to catch missing variables, missing attachments, or invalid addresses
- **Reusable libraries** — save recipient databases and templates so you're not rebuilding them every time
- **Live analytics** — real-time dispatch logs, success/failure tracking, and exportable CSV delivery reports

## Getting Started

### Install

```bash
pip install bit-by-mail
```

Requires Python 3.9 or later.

### Launch

```bash
bit-by-mail
# or, for short:
bbm
```

The app opens automatically in your browser at `http://localhost:8888`.

### Connect your email account

1. Go to **Settings** in the sidebar.
2. Click **Add Account** and enter your SMTP details (e.g. `smtp.gmail.com`, port `587`).
3. Enter your email and password.

> **Using Gmail?** Google blocks sign-ins with your regular password. Generate an [App Password](https://support.google.com/accounts/answer/185833) instead and use that.

### Prepare your recipient list

Recipients are loaded from a CSV file with a header row.

| Column | Required | Notes |
|---|---|---|
| `Name` | Yes | Used for personalization |
| `Email` | Yes | Recipient address |
| `AttachmentFile` | No | Separate multiple files with `;` |
| *anything else* | No | Any extra column becomes a placeholder automatically |

**Example:**

| Name | Email | AttachmentFile | TicketType |
|---|---|---|---|
| John Doe | john@example.com | john_pass.pdf | VIP |
| Jane Smith | jane@example.com | jane_pass.pdf; map.png | Standard |

### Run a campaign

1. **Campaigns → New Campaign**
2. Upload your CSV, or import a saved database
3. Write your subject and body, using placeholders like `{{Name}}` or `{{TicketType}}`
4. Check the **Preview** panel to confirm placeholders render correctly
5. Run **Preflight** to catch problems before sending
6. Click **Start Sending**

## Advanced

**Asset Library** — store image URLs (including Google Drive links) and drop them into your templates without re-uploading each time.

**Throttling** — add a delay (in seconds) between sends in Campaign Settings to stay under provider rate limits and avoid spam filters.

**Resume on failure** — if a campaign is interrupted, bit-by-mail remembers who's already been sent to. Hit send again and it only processes the recipients still marked `PENDING`.

## Troubleshooting

- **Emails aren't sending** — double-check your SMTP host and port, and confirm you're using an app password rather than your account password if your provider requires one.
- **Placeholder shows up literally in the email** (e.g. `{{FirstName}}`) — the column name in your CSV doesn't match the placeholder exactly; names are case-sensitive.
- **Attachment not found errors during Preflight** — check that file paths in `AttachmentFile` are correct relative to where you're running the app, and that multiple files are separated by `;` with no typos.
