Email Deliverability matters!

If you’re working so hard to build an email list to bring in more traffic to your WordPress website! But all your WordPress emails are ending up in audiences’ spam folders, then everything just goes to waste.

Therefore, to ensure the high inbox email delivery of WordPress emails, I will recommend you to use the WP Mail SMTP by WPForms WordPress plugin.

In this article, I will tell you everything about this amazing WordPress Mail SMTP plugin which includes what it is, what it does, and how to set it up on your WordPress website.

What is Email Deliverability and Why it Matters?

The process of delivering an email to your customer’s inbox is referred to as Email Deliverability. 

Email Sent v/s Email Delivered v/s Email Deliverability


Let’s understand the difference between the three with an example. 

Suppose you send an email to a list of 50,000 recipients. 

So the total number of emails sent = 50,000.

Now, analytics might display that out of 50,000 emails, 93% of those emails are “DELIVERED”. 

So the total number of emails delivered = 46,500 (93%).

But just because an email service provider sent and delivered an email to the recipient doesn’t mean that it is delivered to their inbox. 

It might end up in spam due to several reasons which have the least possibility of getting open as the majority of the people never touch the spam folder. 

This inbox delivery is defined as email deliverability.

Why Does Email Deliverability Matters?

It’s pretty clear with the above example, that emails that ended up in inbox have higher open rates, conversion rates, and CTR. 

Now, all the countless hours and efforts you have spent on designing an email, crafting subject lines, and editing the images will end up for nothing if your email won’t reach the inbox!

How do you ensure inbox delivery for your emails?

The answer is right below!
