PHP Script

<?php
if(isset($_POST['submit'])) {
    $to = "jgriffiths100@gmail.com";
    $challenge = $_POST['challenge'];
    $other_challenge = $_POST['other_challenge'];
    $team_structure = $_POST['team_structure'];
    $average_order_value = $_POST['average_order_value'];
    $average_close_time = $_POST['average_close_time'];
    $first_name = $_POST['first_name'];
    $last_name = $_POST['last_name'];
    $company_name = $_POST['company_name'];
    $cohort = $_POST ['cohort'];
    $success_looks_like = $_POST['success_looks_like'];
    $extra_info = $_POST['extra_info'];

    $headers = "From: jgriffiths100@gmail.com" . "\r\n";

    $message = "Application for The Customer Acquisition Accelerator\n\n";
    $message .= "Biggest Challenge: " . $challenge . "\n";
   

    mail($to, "CAA Application", $message, $headers);

    echo "Thank you, your application to join The Customer Acquisition Accelerator has been submitted and a member of the team will get back to you within the next 2 working days.";
} else {
    echo "Error: Form has not been submitted. Please fill out the form and submit it again.";
}
?>

Mail is definitely running on the server. Anyone any ideas?

For $_POST['submit'] to exist there must be an input form element with the name 'submit'.

A better way to check is

if ($_SERVER['REQUEST_METHOD'] == 'POST')  {

    // data was posted - process it

}

Besides what Barand has said you need to know that every input tag has to have a name= attribute for it to recognized by your php code. The id attribute is necessary if you want to reference a field with JS code or to set the focus onto it at page load.
