What is email-service-integration?

A guide to adding email sending to a backend through SMTP or services such as SendGrid, Mailgun, and Amazon SES. It covers templates, validation, retries, and error handling.

Use it to add transactional emails, HTML templates, asynchronous sending, validation, retries, and bulk email workflows.

It helps avoid building email delivery and workflow handling from scratch. It also addresses common failures when sending welcome messages, password resets, and notifications.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00040	$0.00694
Opus 5.5	$0.00016	$0.00278
Sonnet 5.5	$0.00008	$0.00139
Haiku 4.5	$0.00004	$0.00069

Security

Grade A, and why

email-service-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-pipeline.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Overview

Build comprehensive email systems with SMTP integration, third-party email providers (SendGrid, Mailgun, AWS SES), HTML templates, email validation, retry mechanisms, and proper error handling.

When to Use

Sending transactional emails
Implementing welcome/confirmation emails
Creating password reset flows
Sending notification emails
Building email templates
Managing bulk email campaigns

Quick Start

Minimal working example:

# config.py
import os

class EmailConfig:
    MAIL_SERVER = os.getenv('MAIL_SERVER', 'smtp.gmail.com')
    MAIL_PORT = int(os.getenv('MAIL_PORT', 587))
    MAIL_USE_TLS = os.getenv('MAIL_USE_TLS', True)
    MAIL_USERNAME = os.getenv('MAIL_USERNAME')
    MAIL_PASSWORD = os.getenv('MAIL_PASSWORD')
    MAIL_DEFAULT_SENDER = os.getenv('MAIL_DEFAULT_SENDER', '[email protected]')

# email_service.py
from flask_mail import Mail, Message
from flask import render_template_string
import logging
from datetime import datetime
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

logger = logging.getLogger(__name__)
mail = Mail()

class EmailService:
    def __init__(self, app=None):
// ... (see reference guides for full implementation)

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
