Are you looking for the best SMTP service providers? An SMTP service provider helps you reliably send emails from your website to your users.
SMTP servers are specially configured to ensure that your emails reach users’ inbox and don’t end up in the junk mail folder. In this article, we will share the best SMTP service providers with high email deliverability. We will also show you how to send your WordPress emails using these SMTP services.
Why do we need an SMTP Provider For WordPress Emails?
SMTP is the de facto standard by which email on the internet is sent. It authenticates communication between two parties so that the emails you send to your users’ inboxes are more likely to be delivered successfully.
There are several free email service providers from which to choose that utilize the Simple Mail Transfer Protocol (SMTP) for sending emails. For example, you can get a free business email address at Google or Outlook.
This is why you need to sign up with one of the well-known SMTP service providers so that your emails are delivered properly. Don’t worry, a lot of well-known SMTP companies offer free plans that work just fine for most websites.
This is because the default WordPress function for sending email relies on PHP’s mail() function, which is disabled by most hosting providers. Using it may also lead to blacklisting and other nasty side effects.
A lot of WordPress hosting providers don’t have this function configured properly. Even if they did, there are some unsavory providers who disable it completely to prevent people from sending spam emails that can overload their servers.
Using the mail_* functions is a common mistake because it doesn’t require authentication and commonly leads to abuse because of lack of control over the e-mail system.
Even if the mail function works on your WordPress hosting, you may still have to go through some troubleshooting on your own to get a few things running. If you’re using WordPress to send out emails, check to make sure that you have the right SMTP server configured.
