Send emails through your PHP contact form

Solutions on how to make your contact forms successfully send emails

If you're having problems getting your PHP contact form to send emails on your web hosting, then this page should help you solve it.

We explain which settings you need to use to make your contact form work properly on the biggest and most popular web hosting companies.

Form emailing options with PHP

With PHP you have several options when sending emails, the three most common options are listed below:

PHP mail() function

The PHP mail() function can work and is the simplest option, however, it's very limited and not recommended these days as more and more hosting providers and email systems are blocking these.

Email API's with PHP

Working with email service providers API's is also a more common way to send email using PHP. Although these have real benefits (such as making use of advanced service features that may not be available in SMTP), they also have some downsides, mainly that they are all different so if you decide to switch providers then you most likely need to rebuild your PHP email integration. For PHP contact forms, this is not the recommended way unless there's a very good reason.

PHP SMTP Connection

Sending emails through PHP with SMTP is usually the best option for several reasons. You can use a local or remote SMTP Server, and you can make use of powerful libraries that know how to speak to a huge list of SMTP Servers.

SMTP is the recommended option and covered on this page.

If your hosting provider is not yet listed, then we suggest asking your hosting provider this question:

What's the outgoing SMTP details (hostname, port number, username, and password) needed to send emails through PHP?

If you're trying to run your form on your computer on "localhost", then you need to make sure you've correctly set up your mail server. Details on that are out of the scope of this page.

Still not working for you? don't worry, read the form installation guide and contact form troubleshooting for details on how to switch on debug mode and identify your issue.
