What SMTP Replies & Enhanced Status Codes Mean (& Why You Should Care)

It’s that time of year again.

That time where you may not be fully listening to your accountant. Sure, you can see her lips moving, but just can’t understand what she’s saying. You know it’s important and that it should matter—it’s your money, after all. But sometimes it's easier to totally space out, especially when they start talking way over your head.

Email Injection Speed vs Delivery Speed: Which One Is Slowing You Down?

Email is complicated.

If you’re an email marketer or have worked with email servers, you already know that sending email is a complicated process with a lot of moving parts. Unless you know your stuff, it can be hard to pinpoint where certain problems are coming from, and thus how to resolve them.

Six Ways to Make Switching Email Software Easier

Ever feel stuck? Like you’re on autoplay? Me too.

Sometimes when I’m comfortable in the recliner and watching a cliffhanger episode of [insert your latest binge series here], it’s easy to think that letting Netflix autoplay the next episode is simply the universe’s way of exerting the laws of nature over me. After all, objects at rest tend to stay at rest unless acted upon by an outside force. And unless the adult in me kicks in, I will be a law-abiding object of the natural world and remain at rest until either I fall asleep or the power goes out. Oh look—the next episode already started. Might as well watch one more... 

Email Jammed Up? Two Ways We Overcome Email Bottlenecks

Have you ever heard the term, critical path? 

In the world of email sending, you can think of a critical path as a bottleneck. If your email server isn't running as fast as you'd like, it's probably because one (or more) bottlenecks are gumming up the works. There's a chance your email could be slow due to warming-up new IPs, ISP spam filters, or how your delivery throttling rules are configured (you know, the deliverability stuff). But if all of those are in place, then you're down to how fast your software and your server can run. So that's what we're covering today, how we make the software a speed-demon. 

How To Build The Perfect Email Server

I'll admit it. I'm a hardware junkie.

It started when I built my first PC in 1999. I spent hours reading articles on Tom's Hardware and pouring over Egghead and TigerDirect catalogs, obsessing over what components would provide the best bang for my buck. I settled on a K6/2 running at 380 MHz with 128MB of RAM and managed to scrounge a hard drive from a family member who had recently upgraded their PC. 128MB of RAM! I couldn't believe it!

Whether you are a hardware junkie or not, I’d like to share with you some insight into how we select hardware here at DRH. In this post, I’ll focus on performance. While there are reliability considerations to keep in mind when choosing hardware (redundancy, error correction, etc.), I’ll save those for another blog post.

Is Your Email Up To Speed?

In the Driver's Seat with GreenArrow Software.

Imagine a sports car—a really fast one. How do you know it’s fast? Is it the speedometer? The engine? The collection of speeding tickets wedged in the glove box?

Now imagine your email sending software. Is it fast? Exactly how fast is it? And perhaps more important, why does it matter to your bottom line? Today, I want to show you under the hood of our own GreenArrow, and take you for a spin around the track so you can better understand how fast it really is. First, let’s define what kind of speed we’re talking about here. This article is not about how fast your email loads in a user’s mail client, or how fast the ISPs accept your mail. Those topics are important, but they are completely separate from what I want to show you. This article is about the software speed itself—what it can really do for you.

Six Essential Email Tools to Make Your Work Easier

Discover tools our support team says: 'you shouldn't go without'.

Over the past 5+ years working at GreenArrow I've had the opportunity to troubleshoot and solve nearly every different kind of email issue possible. When I do, customers are often curious about how I came up with the answer I provided. Maybe it’s because I’m nerdy, which I am (my wife tells me that all the time). But it’s probably more because our software has so many different tools and resources to make email administration easier.

Email Feedback Loops: What Are They & How To Use Them

Are You “Out of the Loop”?

Ever heard the phrase, “Out of the loop?” It means a critical piece of information has been withheld from you (either on purpose or by accident) that you need in order to make a decision. No one wants to be left out of the loop, especially when it comes to things that can cost you time and money, like customer feedback.

[Our Team] The Freedom I Found In A $462 Mistake

I have to confess, I am thrifty. Ask my wife. 

She might say I'm a penny-pincher; I say 'frugal' and 'penny-wise.' If there’s a deal or a promotion, I’m in! If there’s not, you bet I’m going to ask for one. I like quality stuff too and I believe you-get-what-you-pay-for, but that doesn’t mean you have to overpay, right?

Naturally, this finance-saavy trait follows me in my personal and professional life too. So when I made a $462 blunder at work, my heart sank. But when I took the leap to share that blunder with our staff, I was surprised how it felt. This mistake felt like…freedom.(Right back at you, George Michael.)

[Video] What High Voltage Wires and Email Servers Have in Common

In today's team meeting our CEO, David Harris offered a comparison between the kind of maintenance we often perform on live email servers and something far more dangerous (and cooler).
