Hello @daniel_keay,
Please create a sample file on server and add below code in it with exists email address in it.
<?php
// the message
$msg = "First line of text\nSecond line of text";
// use wordwrap() if lines are longer than 70 characters
$msg = wordwrap($msg,70);
// send email
mail("someone@example.com","My subject",$msg);
?>After creating above file then please execute it on the browser and check in your inbox and spam folder. If you didn't get an email then you need to hosting provider to enable mail service.
Otherwise, You can install third party mail service provider extension and after configure mail configuration you can also send email in Magento store. You can find out email extension here
