WP-EMail for WordPress

On selected posts and pages, type the shortcode into the content:

[email_link]

This works in both block and classic themes, and puts the link exactly where you want it rather than on everything.

On every post and page, call the template tag from your theme instead. In a classic theme, open wp-content/themes/<YOUR THEME NAME>/index.php — or single.php, page.php, and so on — find:

<?php while ( have_posts() ) : the_post(); ?>

and add this inside the loop, where you want the link to show:

<?php if ( function_exists( 'email_link' ) ) { email_link(); } ?>

Use one or the other, not both, or the link appears twice.

If the link is there but clicking it gives a 404, re-save your permalinks under WP-Admin -> Settings -> Permalinks. The plugin registers its /email/ endpoint on activation, but a site with unusual rewrite rules can need the nudge.

Everything else is configured under WP-Admin -> E-Mail -> Settings, which has two tabs: Settings for the link, the form and delivery, and Templates for the eight message templates. The log of what has been sent is under WP-Admin -> E-Mail -> Manage E-Mail.

Filters Use wp_email_capability to hand a screen to a capability other than the default. The logs screen is gated on manage_email and the settings screen on manage_options:

add_filter( 'wp_email_capability', function ( $capability, $context ) { return 'logs' === $context ? 'edit_posts' : $capability; }, 10, 2 );

Use wp_email_form_field_values to pre-fill the form. The plugin uses it itself to fill in a logged-in visitor’s name and address:

add_filter( 'wp_email_form_field_values', function ( $values ) { $values['yourremarks'] = 'Thought you would like this.';

return $values; } );

The other three are wp_email_ipaddress (the address a send is attributed to), wp_email_template_redirect (whether the plugin takes over the request for its own endpoints) and wp_email_trust_proxy (whether the usual forwarding headers may be trusted).
