Email Sender with Template Inheritance in Go

This project is a Go application that sends emails using HTML templates with inheritance. It supports sending emails with attachments and plain text versions of the HTML content. The email templates are styled using Google Fonts and include a header, footer, and disclaimer.

Features

• Send emails with HTML content
• Template inheritance for reusable HTML structures
• Send plain text versions of the emails
• Attach files to emails
• Use environment variables for configuration

Prerequisites

• Go 1.16+
• SMTP server credentials
• Environment variables setup

Getting Started

Clone the Repository

git clone https://github.com/Nneji123/golang-html-email.git
git clone https://github.com/MoksDa3rd/golang-html-email.git
cd golang-html-email

Install Dependencies

go get -u github.com/jordan-wright/email
go get -u github.com/joho/godotenv

Setup Environment Variables

Create a .env file in the root of your project and add your SMTP server credentials:

EMAIL_HOST=smtp.your-email-provider.com
EMAIL_HOST_USER=your-email@example.com
EMAIL_HOST_PASSWORD=your-email-password

HTML Templates

Create two HTML template files, base.html and content.html, in the same directory as the Go program. These templates will define the structure and content of your emails.

Running the Program

1. Make sure you have the necessary environment variables set up in the .env file.
2. Ensure your HTML templates (base.html and content.html) and any attachment files are in the same directory as the Go program.
3. Run the program:

go run main.go

Example Usage

The main.go file includes an example usage of the SendEmail function. Modify the example to suit your needs, including setting the email subject, recipients, context variables, and attachments.
