But, we want to help you out by providing a detailed list of WP Mail SMTP Alternatives.

One cannot deny the fact that the WP Mail SMTP is one of the best plugins for managing your outgoing WordPress emails. But this might not be the case always. Although its usage is highly recommended, sometimes it doesn't quite work great.

However there might be a chance that you are looking for WP Mail SMTP plugin alternative. So if this the case, then here in the post you will get to know a little about SMTP and seven best WordPress SMTP plugins to install and have a simpler way to use an SMTP service with WordPress.

What is SMTP and Why you Need it?

In short, SMTP stands for Simple Mail Transfer Protocol, which is a protocol used for sending and receiving emails. While sending an email, an SMTP server breaks down your email into its relevant parts and helps move it further from your email client to your recipient’s email client. And also, most of the emails there in your inbox are probably from an SMTP server.

Now actually what happens is that if you know WordPress uses the wp_mail function to send emails via PHP mail. Meaning your site is sending emails via the same server that your site is hosted on, which is certainly not optimized for sending emails. Of course, it does work but lacks authentication. This is the reason why emails send via WordPress’ built-in PHP mail often land up in spam.

But with SMTP, this is not the case. You can order your WordPress site to send emails via a properly-configured SMTP server, instead of WordPress site’s server. And with this setup, your WordPress site sends the email to the SMTP server, processes the email and finally sends it on to the proper inbox.

Since the SMTP server is well configured to handle sending and receiving emails with the appropriate authentication in place, your emails have a higher chance of making it to recipients’ inboxes. You need SMTP not only for this purpose but also you can use the SMTP server for free email services, like Gmail and Hotmail.

Thirdly, if you are into a serious business where deliverability is of utmost importance to you, then using a third-party and dedicated SMTP server for sending emails is a must. It may include Mailgun, Sendgrid, and Mandrill, etc.
