SMTP2GO API

Go wrapper around the SMTP2GO /email/send API endpoint.

Installation

go get github.com/smtp2go-oss/smtp2go-go

Add the import in your source file

import "github.com/smtp2go-oss/smtp2go-go"

Usage

Sign up for a free account here and once logged in navigate to the Settings -> Api Keys page, create a new API key and make sure the /email/send endpoint is enabled:

Once you have an API key you need to export it into the environment where your Go application is going to be executed, this can be done on the terminal like so:

`$ export SMTP2GO_API_KEY="<your_API_key>"`

Or alternatively you can set it in code via

import "os"
os.Setenv("SMTP2GO_API_KEY", "<your_API_key>")

Then sending mail is as simple as:

package main

import (
	"fmt"
	"github.com/smtp2go-oss/smtp2go-go"
)

func main() {

	email := smtp2go.Email{
		From: "Matt <[email protected]>",
		To: []string{
			"Dave <[email protected]>",
		},
		Subject:  "Trying out SMTP2GO",
		TextBody: "Test Message",
		HtmlBody: "<h1>Test Message</h1>",
	}
	res, err := smtp2go.Send(&email)
	if err != nil {
		fmt.Printf("An Error Occurred: %s", err)
	}
	fmt.Printf("Sent Successfully: %s", res)
}

You can also send Asynchronously:

package main

import (
	"fmt"
	"github.com/smtp2go-oss/smtp2go-go"
)

func main() {

	email := smtp2go.Email{
		From: "Matt <[email protected]>",
		To: []string{
			"Dave <[email protected]>",
		},
		Subject:  "Trying out SMTP2GO",
		TextBody: "Test Message",
		HtmlBody: "<h1>Test Message</h1>",
	}

	var c chan *smtp2go.SendAsyncResult = smtp2go.SendAsync(&email)
	res := <-c
	if res.Error != nil {
		fmt.Printf("An Error Occurred: %s", res.Error)
	}
	fmt.Printf("Sent Successfully: %s", res.Result)
}
