“Your email failed to be delivered”. Again. Why? Even when you think you configured everything properly, there are various reasons why your email might bounce. Some might be really your fault but most of the time, it’s things out of your control that cause emails to come back in a matter of seconds. Let’s analyze each case one by one and talk about the difference between a hard bounce and a soft bounce.

As one of Microsoft’s most successful programming languages, it’s safe to say that C# enjoys a lot of popularity and adoption among developers. 

These same developers are behind the creation of everything from desktop and web applications to enterprise software and games, which often need to have an email-sending functionality for distributing email notifications to users.

So how do developers incorporate the email-sending functionality into their software and send emails with C#? We tackle this question in the text below, so if you’re interested, keep on reading!

Google Sheets are great! Need to perform some advanced calculations? Store an enormous amount of data? Fetch from external services on a regular basis? They can do it all and a lot more too. Another useful but maybe not so well known feature is the ability to send emails from Google Sheets. How does it work? How do you set it up? Let’s see!

How would you feel if anyone could send emails from your mail server? Greenlight for spammers – no way! That’s why Google and other email service providers protect their servers from unauthorized use. Senders need to authenticate and prove that they have a valid account. If they don’t, the server will reject their request. All of this is possible with SMTP authentication, also known as SMTP AUTH.

Very often, we’re asked to extract some data from a database. If the request repeats regularly, it’s worth looking into automating it so you don’t have to perform this boring procedure over and over again. For this reason, you’ll probably want to send emails from SQL Server with the predefined content. And it’s not that hard to set up.

Of course, emailing in SQL Server doesn’t need to only be about exporting data. You may simply want to keep yourself (or a colleague of yours) updated when, for example, a backup is finished or a programmed job fails miserably. With built-in functionalities, this can easily be done too.

We cover several different approaches and let you choose which works best for your needs.

Every email sending provider has its own maximum email size limit. However, there is no unique standard – limits are dictated mostly by performance and security reasons. There are many things you should keep in mind when preparing your email notifications or newsletters: from the maximum size of file attachments and HTML part to the email client your recipients will most likely use. Also, there are some not so obvious factors, which impact the actual email size and deliverability.

There it goes. Yet another email bounces because a user mistyped it or assumed (rightly so) that your site would accept hwebfdherw@fhberwfuy as a valid email address. If your list is flooded with such addresses, you are likely to experience poor deliverability or your users getting locked out of their accounts more often than you would wish. Luckily, it’s easy to set up a decent email validation in HTML5. Let’s see how.

When you gather emails from your users or visitors, you want to make sure they’re valid and functional. Otherwise, you risk cutting users off from their accounts or cluttering your database with fake addresses you’ll have no use for. Luckily, there are several fairly obvious approaches to validating emails in Python.

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!
