Are you looking for the best WordPress SMTP plugin on the market?
If you’re having problems sending emails from your WordPress site, you’re not alone.
A WordPress SMTP plugin ensures that emails are delivered to your audience’s inbox, NOT their spam folder.
So, in this article, we’ll show you some of the best WordPress SMTP plugins. Here are the plugins we’ll cover:
- WP Mail SMTP
- Easy WP SMTP
- WordPress SMTP Mailer
- WP Mail SMTP by Mailbank
- WP Gmail SMTP
- Post SMTP Mailer/Email Log
Before we get into the best SMTP plugins, let’s take a quick look at what an SMTP plugin for WordPress is and why your site needs one.
Why Use a WordPress SMTP Plugin?
Many WordPress sites need to send emails for different purposes, like:
- Account registration
- Password recovery
- Order confirmations
These are considered “transactional emails” and are important for sending critical information to your leads or customers.
By default, your WordPress site uses the PHP mail() function from PHPMailer to send emails. Since it’s notoriously hackable, some web hosts have disabled the use of the mail() function altogether.
Major email providers (like Google) do rigorous testing to verify that the email sender is who they say they are. And, if your WordPress email can’t pass the test, it’s destined for the junk folder.
This poses a big problem, especially for WooCommerce stores, because they simply can’t afford to have customers/clients miss important emails.
Here is where the Simple Mail Transfer Protocol (SMTP) comes in.
SMTP works by bypassing the WordPress wp_mail() function and forcing it to use your SMTP settings. This means that you can set it to use whatever email you want just by entering your SMTP options in the dashboard.
And the best WordPress SMTP plugins have a quick and easy setup, as you’ll see in a moment.
Of course, there are so many plugins on the market. How do you find the right one? Take a look at some of the best SMTP plugins below.
Best WordPress SMTP Plugins
Most of the plugins on this list have a free plan to set up SMTP and easily configure your email delivery with the proper settings.
But before we get started, we should clarify something: none of these tools will help improve deliverability rates if you don’t have customers to send these transactional messages to.
In other words, if nobody signs up for your offers, then you’ve got a bigger problem than just deliverability.
To convert more visitors into registered users, customers, and subscribers, TrustPulse is an excellent tool:
TrustPulse is the world’s #1 social proof software. That means it leverages FOMO (“fear of missing out”) to inspire your audience to action.
How? With social proof notifications.
These are small messages that display when people have taken positive actions with your site. You’ve probably seen these before. They look something like this:
These messages are displayed on key pages of your site to encourage other users to take action.
You can add social proof notifications to any page to boost conversions and show how popular your mailing list is. When other visitors see this, they’ll want to receive the same benefits.
And, as a result, you’ll be able to grow your customer/subscriber base much faster.
In fact, we’ve seen TrustPulse users see an instant boost in conversions by up to 15%.
