A contact form is one of those parts of a website that is easy to forget about once it has been set up. You might assume that if the form is sitting there on the page and a visitor sees a “Thank you” message after submitting it, everything is working exactly as it should.
Unfortunately, that is not always the case.
A form can appear to submit successfully while the notification email never reaches your inbox. And if that happens quietly in the background, you may not realise that potential enquiries are being missed.
Start with a simple test
The easiest way to check your form is to use it exactly as a customer would.
Send yourself a test enquiry and check:
- Does the form submit without showing an error?
- Do you see the expected confirmation message?
- Does the notification email arrive?
- Does it land in your inbox rather than spam or junk?
- If an automatic confirmation is sent to the customer, does that arrive too?
It only takes a few minutes, but it is worth doing occasionally, particularly after website updates, changes to your email service or changes to your domain settings.
Why form emails sometimes go missing
When a WordPress website sends a contact form notification, the message usually passes through your web hosting environment before reaching your email provider.
That is where problems can occur.
The form itself may have worked perfectly, but the email notification can still be delayed, rejected or sent to spam. This means a visitor may have successfully submitted their enquiry even though you never received the email telling you about it.
What does an SMTP plugin do?
This is where an SMTP plugin can help. SMTP stands for Simple Mail Transfer Protocol. You do not need to remember the technical name – the important part is that it gives WordPress a more reliable and authenticated way of sending email.
Instead of relying only on the web server’s basic mail function, an SMTP plugin can connect WordPress to a proper email service or mail server.
For WordPress websites, plugins such as WP Mail SMTP are commonly used for this purpose. Once configured correctly, SMTP can help improve delivery of website-generated emails such as:
- contact form notifications
- password reset emails
- WooCommerce order emails
- booking confirmations
- membership or account emails
Should every website use SMTP?
Not every WordPress website necessarily needs an SMTP plugin. If your website and email are hosted with the same provider, and that hosting environment is properly configured to send website email, your form notifications may already be delivered reliably without one.
For example, sites with both web and email hosted through The Web Factory generally send website-generated emails successfully without needing an additional SMTP plugin.
I am more likely to configure SMTP when a client’s email is hosted separately through a service such as Google Workspace or Microsoft 365, or where there have been problems with website emails reaching their destination.
That is particularly relevant for websites receiving:
- customer enquiries
- online orders
- booking requests
- registrations
- quote requests
- other time-sensitive notifications
Tip: keep a copy of form entries
Where possible, I also like contact forms to store submissions inside WordPress rather than relying only on email notifications. That way, if an email ever goes missing, there is still a record of the enquiry in the website dashboard.
It gives you a useful second layer of protection.
A small check that can prevent a bigger problem
Contact forms are easy to take for granted because, most of the time, they simply work. But if enquiries are important to your business, it is worth testing them occasionally rather than waiting for a customer to tell you something is wrong.
If you are unsure whether your website’s contact forms are sending reliably, or whether SMTP is configured correctly, I can take a look and help you work out what is happening.
