SugarPost

PHP port of charmbracelet/pop — send emails from PHP via Resend API or direct SMTP.

Features

• Dual transport — send via Resend HTTP API or raw SMTP
• Email value object — from, to, cc, bcc, subject, body, HTML body, reply-to, attachments
• File attachments — attach files from paths or raw content with MIME detection
• Inline attachments — embed images inline (CID references)
• CC/BCC support — full carbon-copy / blind carbon-copy routing
• STDIN compose — read email body from STDIN for shell pipeline use
• Environment config — RESEND_API_KEY, POP_SMTP_*, POP_FROM, POP_SIGNATURE
• PHP 8.1+ — pure PHP, no extensions required beyond cURL (for Resend transport)

Install

composer require sugarcraft/sugar-post

Quick Start

Resend API

use SugarCraft\Post\{Email, Mailer, ResendTransport};

$transport = new ResendTransport('re_xxxxxxxxxxxxx');
$mailer = new Mailer($transport);

$email = new Email(
    from:    '[e-mail]',
    to:      ['[e-mail]'],
    subject: 'Hello from SugarPost',
    body:    'Sent via the Resend API.',
);

$mailer->send($email);

SMTP

use SugarCraft\Post\{Email, Mailer, SmtpTransport};

$transport = new SmtpTransport('smtp.gmail.com', 587, 'username', 'password');
$mailer = new Mailer($transport);

$mailer->send(new Email(
    from:    '[e-mail]',
    to:      ['[e-mail]'],
    subject: 'Hello via SMTP',
    body:    'Sent directly via SMTP.',
));

Attachment

$email = new Email(/* ... */);
$email = $email->withAttachment('invoice.pdf', '/path/to/invoice.pdf');
$mailer->send($email);

CLI

pop --from "[e-mail]" --to "[e-mail]" --subject "Hello"
# Body read from STDIN

Environment variables:

export RESEND_API_KEY=re_xxxxx                # Resend API key
export POP_SMTP_HOST=smtp.gmail.com           # SMTP host
export POP_SMTP_PORT=587                      # SMTP port (default: 587)
export POP_SMTP_USERNAME=user                 # SMTP username
export POP_SMTP_PASSWORD=pass                 # SMTP password
export POP_FROM=[e-mail]                # Pre-fill From address
export POP_SIGNATURE="Sent with SugarPost"    # Appended to body

Architecture

• Email — immutable email message value object
• Attachment — immutable file attachment (path or inline content)
• Transport — interface for sending implementations
• ResendTransport — sends via Resend REST API (HTTPS)
• SmtpTransport — sends via direct SMTP (TCP/TLS)
• Mailer — high-level API wrapping a Transport
