Simple example of code implementation.

package main

import (
	"fmt"
	mailer "github.com/thiagozs/mailer-go"
	"time"
)

func main() {

	//Sendgrid Instance
	sg := mailer.NewMailerSendGrid(os.Getenv("SENDGRID_API_KEY"))
	sg.Delay = time.Second * 5

	//Mailgun Instance
	mg := mailer.NewMailerMailGun(os.Getenv("MAILGUN_DOMAIN"),
		os.Getenv("MAILGUN_API_KEY"),
		os.Getenv("MAILGUN_PUB_KEY"))
	mg.Delay = time.Second * 5

	//Gmail Instance
	gm := mailer.NewMailerGmail(os.Getenv("GMAIL_LOGIN"),
		os.Getenv("GMAIL_PASSWD"))
	gm.Delay = time.Second * 5

	// --------------

	// Sendgrid configs
	sg.ConfigEmail = mailer.ConfigEmailSendgrid{
		ContentHTML:      "<b>Test</b>",
		ContentPlainText: "Test",
		EmailFromName:    "Thiago Zilli",
		EmailFrom:        "[email protected]",
		EmailToName:      "Client Name here",
		EmailTo:          "[email protected]",
		Subject:          "Test email",
	}

	// Mailgun configs
	mg.ConfigEmail = mailer.ConfigEmailMailGun{
		ContentPlainText: "Test",
		EmailFrom:        "[email protected]",
		EmailTo:          "[email protected]",
		Subject:          "Test email",
	}

	// Gmail Configs
	gm.ConfigEmail = mailer.ConfigEmailGmail{
		ContentHTML: "<b>Test with Gmail</b>",
		EmailFrom:   "[email protected]",
		EmailTo:     "[email protected]",
		Subject:     "Test email",
	}

	// --------------

	// Send email by Sendgrid
	if err := sg.SendMail(); err != nil {
		fmt.Printf("Sendgrid Error: %s\n", err.Error())
	}

	// Send email by Mailgun
	if err := mg.SendMail(); err != nil {
		fmt.Printf("Mailgun Error: %s\n", err.Error())
	}

	// Send email by Gmail
	if err := gm.SendMail(); err != nil {
		fmt.Printf("Mailgun Error: %s\n", err.Error())
