Why Your Website Needs an SMTP Plugin to Send Emails Properly

If you’ve ever wondered why your website emails aren’t getting delivered—or worse, end up in the spam folder—you’re not alone. Many website owners experience this, especially when using contact forms, order notifications, or customer inquiries. The good news? There’s a simple and reliable fix: using an SMTP plugin.

What Happens Without an SMTP Plugin

By default, WordPress uses a function called PHP mail() to send emails. This is a basic method that sends emails directly from your web server without any verification or login. And that’s where the trouble starts.

Most modern email providers like Gmail, Outlook, and Yahoo have strict filters to prevent spam. If your website sends an email that isn’t verified or authenticated, these providers are likely to block it or send it straight to the spam folder.

Why Emails Fail Without SMTP

  • No Authentication: Emails sent via PHP mail() aren’t verified. There’s no proof that your website is allowed to send that message.
  • Low Trust: Email providers treat unauthenticated emails as suspicious. They often assume it’s spam or phishing.
  • No Tracking: If emails fail, you have no logs or insights into what went wrong.

How SMTP Fixes It

SMTP stands for Simple Mail Transfer Protocol, and it’s the industry-standard method for securely sending emails.

When you use an SMTP plugin (like WP Mail SMTP), your website:

  • Authenticates every message: It logs in to your email provider (e.g. Google Workspace) before sending
  • Sends securely: All messages are encrypted and verified
  • Increases deliverability: Emails are less likely to get flagged as spam
  • Provides logs: You can see what was sent, when, and if it failed

Real-World Analogy

Think of PHP mail() like posting a letter without a return address or stamp. It might get there, or it might get tossed in the bin.

SMTP is like handing your letter to Royal Mail with ID, tracking, and full verification. It’s trusted and reliable.

The Bottom Line

If you’re running a website that needs to send reliable emails—whether for contact forms, user registration, or e-commerce—using an SMTP plugin is a must.

It’s the difference between your message landing in the inbox or vanishing into the void.

I can’t sing the praises of Madhouse Media enough. So much so that I have recommended them to several friends and acquaintances who now all use Madhouse Media for their website or their social media and marketing. From start to finish they listened, offered help and guidance and found the right product/s I needed, without taking your eyes out like some other companies. The best thing you can do is make that first contact, after all, what have you got to lose? If they can help you they will give you all the options they can, if they can’t help you they’ll tell you and point you in the right direction. But if you don’t speak to them then you’ll never know. It’s the best decision I’ve made. My magazine now runs smoothly and with no hassle, any issues have been dealt with straight away. They have freed up my time to concentrate on other aspects and that has been perfect for me.

I contacted madhouse media for 1000 flyers A5 single sided, however, they gave me a great deal for 5000 double sided. I sent the photos over to them along with my logo and information and they did the rest. There was a problem with the resolution of the logo I sent over so they redesigned it for me at a great price and it looks fantastic. They were in constant contact with me sending over initial drafts and final drafts and once the final draft was accepted the flyers were with me a couple days later. I will be using madhouse media Ltd again in the future for more flyers and business cards. Highly recommended!
