Blog / WordPress / 15 Best SMTP Email Services for Email Delivery

From recovering lost passwords to making new accounts, WordPress uses email for many tasks. However, the Content Management System’s (CMS) included email feature isn’t the most reliable. Therefore, we recommend using an SMTP service to send emails through your WordPress site.

In this post, we’ll explain what an SMTP service is and why you might need one. Then, we’ll provide you with 15 of the best SMTP email services, detailing their key features and pricing information. Let’s jump in!

What is an SMTP Server?

A Simple Mail Transfer Protocol (SMTP) server uses proper authentication for sending emails over the internet. It ensures that your emails are successfully delivered. Moreover, it makes sure that messages don’t end up in the Spam folder in your users’ inboxes.

There are free and paid SMTP service providers. However, the free options limit how many emails you can send daily.

Some free email service providers, such as Google, don’t let transactional emails be sent through WordPress websites. These are messages delivered to individuals. Therefore, it’s a good idea to use a premium SMTP service.

Do I Need an SMTP Service?

If you run a business website, one-on-one commutation with your customers is essential. Furthermore, you’ll need transactional email functionality to configure specific triggers. These triggers can automatically send emails to users based on their activities. Therefore, you’ll need an SMTP service.

Some hosts, such as SiteGround,  include SMTP servers for their customers. However, this isn’t always the case. For instance, Cloudways and Pressable do not. If you can’t access an SMTP service through your hosting provider, you’ll need to outsource to a third-party company instead.

15 Best SMTP Email Services

Now we understand more about SMTP email services and why you might need one. So, let’s get into some of the top options. Below are 15 of the best SMTP email services!
