Go-EZmail: quick and easy email sending with Go

Usage of this small and simple package should be pretty self explanatory. However, feel free to see the example section below for usage with package main. Also, I'll be working on a more thorough explanation on my site and (possibly) adding this package to GoDoc.

There are two main things you have to know before you use this package:

1. Go.
2. There are actually two packages.
   • The most useful of which is the main one, go-ezmail.go, which can be imported with import "github.com/benobro/go-ezmail" (the package can be called with ezmail)
   • The second one adds an option for a code (the variable is called yourcode). This is useful if you'll be using the email to send a verification link/code, for example. It can be imported with import "github.com/benobro/go-ezmail/with-code" and called with ezmailcode.

For help with net/smtp, the driving force behind this package, see the official Go documentation.

Example:

This example is for the ezmail package.

Remember, if you're using Gmail, you'll need to enable less secure apps access.

package main

import (
	"github.com/benobro/go-ezmail"
)

func main(){ 
	ezmail.SendMail("SEND@email.com", "YOUR-SECRET-PASSWORD", "smtp.gmail.com", 587, "RECEIVE@email.com", "test", "test ")
}

Here's an example of ezmailcode. The code I generate here is a 50 character string, containing a-z lowercase, A-Z uppercase, and 0-9. That string is then sent along with the message in ezmailcode.SendMail

package main

import (
	"github.com/benobro/go-ezmail/with-code"
	"math/rand"
	"time"
)

func main(){ 
	yourcode := RandomString(50)
	ezmailcode.SendMail("SEND@email.com", "YOUR-SECRET-PASSWORD", "smtp.gmail.com", 587, "RECEIVE@email.com", "test", "test ", yourcode)
}

func RandomString(strlen int) string {
        rand.Seed(time.Now().UTC().UnixNano())
        const chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
        result := make([]byte, strlen)
        for i := 0; i < strlen; i++ {
                result[i] = chars[rand.Intn(len(chars))]
        }
        return string(result)
}
