How to programmatically send an email in WordPress

While developing another plugin for WP, I remembered a small issue I once ran into — programmatically sending email messages. There's really nothing complicated about it, but still, it might be useful to someone.

Usually, across the web, I’ve seen the following code:

wp_mail(
	'to_email@example.com',
	'Email Subject',
	'Email Body'
);

What does it do? It sends an email — correct. But! The sender name will be “WordPress” and the sender address will be “wordpress@” + your domain.
What if we want to change that? Personally, I like using “no-reply” as the sender.

You can fix that by adjusting the code like this:

wp_mail(
	'to_email@example.com',
	'Email Subject',
	'Email Body',
	array(
		'From: no-reply <no-reply@example.com>',
));

Better now, right?

Wait a minute — it’s also nice when someone addresses us by name. And in the “To” field, we’ve only specified the email address.
How can we fix that? — in a similar way 🙂

wp_mail(
	array(
		'ToName <to_email@example.com>',
	),
	'Email Subject',
	'Email Body',
	array(
		'From: FromName <from_name@example.com>',
));

Of course, this is not the full functionality of the `wp_mail` function — check out the source code and you’ll see for yourself.
As for me — that’s all I have to say about it for now 🙂
