What Is Email Deliverability?
At first glance, email deliverability can seem a little complicated. But it’s not all that hard to understand with some explanation, so we’ll clarify it here.
Email deliverability is the ability of emails to be delivered to someone’s inbox.
This is a metric that you can use to understand the likelihood of your email messages being placed in your recipient’s inbox.
Having strong email deliverability is absolutely vital to running successful email campaigns. And, your successful email campaigns can make your small business more money. You can see how powerful emails can be with just a quick glance at some email marketing statistics.
And that’s why paying attention to email deliverability is really important for small business owners.
So now that you know what email deliverability is, let’s dive into some of the most common questions we get asked about it.
Delivery vs Deliverability
It’s not uncommon for people to mistake Delivery vs Deliverability. They assume they’re the same thing.
But they aren’t the same. So here’s a simple breakdown of the difference:
- Email Delivery is whether or not your email was received by the recipient’s inbox servers. Things that impact email delivery rates include email list quality, bounces, etc.
- Email Deliverability is where your email goes once it’s been accepted by the recipient’s inbox servers. An email that gets delivered but ends up in a spam folder is a deliverability issue.
To summarize the difference on a very basic level we could say:
Email Delivery = if an email is received.
Email Deliverability = where an email is received.
It’s important to note that even if your email marketing service dashboard is showing you have a good email delivery rate (let’s say it’s 98% with a few bounces here and there), that doesn’t necessarily mean you have a good email deliverability rate.

What Affects Email Deliverability?
Wondering what affects email deliverability? Whenever you send an email to someone, their inbox provider runs checks on that incoming message.
They’ll check for a few things, but the one that has the biggest impact on your email deliverability is authentication.
So if you take one thing away from this ultimate guide, it’s this:
The #1 thing that affects WordPress email deliverability is authentication.
There are a few things that go into email deliverability as well, like Proper IP allocation and avoiding Blacklisting. However, since most email deliverability issues with WordPress are due to emails not being authenticated, we’ll focus on that in this guide.
So now that you understand how impactful authentication is, let’s find out how you can fix it to improve your email deliverability up next.
How Do I Fix Email Delivery Problems?
So, how do you increase email deliverability? You’ll want to start with authentication.
Maybe you ended up here because you searched the web for ‘Why are my emails getting blocked?”
Well, as you’ve learned in this guide, email deliverability failure happens most often when your message went to a spam folder or was blocked by an ISP – usually due to authentication issues.
So if you want to increase email deliverability fast, the most effective way to do it is by authenticating.
Authentication means that the email’s origin is the same website that it says it’s been sent from.
An email being sent from one place but with a different “from” name can be considered ‘spoofing’. This could easily happen when your contact form sends you a notification when a form is completed by using the email of the person who completed it as the “from” sender (but it’s really coming from your website, which is a different domain.
And that’s why authentication is so important!
Luckily, authenticating your emails is a simple process with the right tool. Just think of it as ‘telling’ mailbox providers that you’re not spam.
You’ll want the free email deliverability tool WP Mail SMTP. It’s a plugin used by millions of WordPress websites. And, it works great for authenticating emails.
Even though it powers 1/3 of the world’s websites, WordPress is known for having issues with email deliverability.
