Setting up Go with SMTP2GO

Instructions for setting up a Go wrapper around the SMTP2GO /email/send API endpoint.

Step 1

To install:</>

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

Add the import in your source file:>

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

Step 2

Log in to your SMTP2GO account and navigate to:

Settings -> Api Keys

Create a new API key and make sure the /email/send endpoint is enabled.

Step 3

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

$ export SMTP2GO_API_KEY=""

Or alternatively you can set it in code using the:

std::env::set_var

function.

Step 4

Then sending mail is as simple as:

	match smtp2go::Email::new()

		.from("Matt ")

		.to(&[

			"Dave ".to_string()

		])

		.subject("Trying out SMTP2Go")

		.text_body("Test message")

		.send().await {

			Ok(response) => println!("Message Successfully Sent - {:?}", response),

			Err(error) => println!("Message failed: Error: {:?}", error)

		};
