In the blog post Best Free SMTP Servers, we touched on the cloud-based solutions for sending emails. These are quite common for all sizes of projects. But what if you don’t want to use the email relay services of Gmail SMTP or its alternatives? In this article, we’ll teach you how to set up a local SMTP server and get rid of any email-sending dependencies.

If you are up to reading this post, you already know what SMTP is and how the SMTP server works. So, we’ll spare you an introduction to this. What you need is a reliable and, equally importantly, free service that will let you send bulk emails and transactional emails. That’s why you’re here. We’ve analyzed dozens of worthwhile solutions and picked 11 free SMTP servers you can rely on. 

Go (informally known as Golang) is a popular back-end language born in Google labs back in 2007. The devs behind it were all frustrated with the omnipresent C++ (wonder why!) and, as history shows over and over again, such frustration often leads to building something great. Now, many years later, you might be sitting with a freshly delivered Gopher mascot on your desk, working on a Go project you picked up just for fun… and you’re gradually starting to regret your decision because you got stuck on such a simple thing as sending emails.

Despair no more! We’re covering various approaches for you so you can decide how to best handle such a useful functionality. Let’s get started!

When a new user clicks on the Sign up button of an app, he or she usually gets a confirmation email with an activation link (see examples here). This is needed to make sure that the user owns the email address entered during the sign-up. After the click on the activation link, the user is authenticated for the app.

From the user’s standpoint, the email verification process is quite simple. From the developer’s perspective, things are much trickier unless your app is built with Laravel. Those who use Laravel 5.7+ have the user email verification available out-of-the-box. For earlier releases of the framework, you can use a dedicated package to add email verification to your project. In this article, we’ll touch upon each solution you can choose. 

Magento is one of the most commonly used e-commerce platforms. You might not even realize it, but you’re probably buying from a few Magento-powered web stores on a regular basis.

As is often the case, there are several possible approaches. Let’s explore them one by one.

Windows PowerShell is mostly known as a command-line shell used to solve some administration tasks in Windows and apps running on this OS.

Let’s say you’ve picked Microsoft Azure as a cloud-computing platform for your environment. You may need it for hosting your app, or whatever.

You’ll find the answer below, as well as the details about how to send emails from Azure.

When it comes to adding email functionality to your PHP app, PHPMailer class is the winning option. It is compatible with most of the PHP frameworks (Laravel or Symfony are based on the SwiftMailer library, though, but it is still possible to use PHPMailer as well.) PHPMailer provides powerful functionality to create HTML emails with attachments and send them to multiple recipients via SMTP or a local webserver. Learn how to easily use all these options in this tutorial!
