The best professional SMTP servers to deliver your emails

A professional SMTP server can enhance the sending and delivery of your emails. And it’s even more crucial for sending those originating from your WordPress site.

A Simple Mail Transfer Protocol (SMTP) server, as the acronym suggests, is the service responsible for transmitting emails and delivering them to your recipients’ inboxes.

It operates like a virtual mailman that manages the sending process: it receives the message and ensures it’s efficiently and promptly delivered to the final recipient.

If you’ve created your website using WordPress, you probably already know that the popular CMS relies on emails for several crucial purposes, including new account registration, password recovery, and sending notifications about changes or updates.

However, without a professional SMTP server, there’s a risk that these emails may not reach their destination (or may not arrive at the right time), causing significant inconvenience to your audience.

But let me explain further.

WordPress relies on PHP Mail for the default sending of emails, and due to some recurring issues, relying on this service can cause delays in delivery, compromising user experience and communication with customers. Integrating an SMTP server with WordPress offers numerous advantages, including higher delivery rates, greater reliability, and a better user experience.

An integrated SMTP server optimizes the email sending process, ensuring that important communications reach recipients promptly and reliably.

But what are the best SMTP services available to you that offer integration with WordPress?

Let’s see them right away.
