Email Essentials vastly reduces the chances of your emails being marked as spam or being rejected. Originally a debugging tool, it has grown into a full-fledged email enhancement plugin. Please note that this plugin is not a “we support any type of transport” Email plugin. For other protocols than SMTP, but rather to enhance the email sending capabilities of WordPress. If you need to send emails with other protocols than SMTP, this plugin is not for you. You might want to look at plugins like Post SMTP (not affiliated). And since version 6.0.0, after more than 10 years of development and internal use, this plugin is now a FOSS plugin, meaning it is free to use, modify and distribute under the GPLv2 license. In return, we ask you to support the development of this plugin by contributing to the codebase, reporting bugs, and helping others in the community. Responsible disclosure: If you find a vulnerability, please email us at [email protected]. Features Set a good From name and email address, automatically correcting it if needed. For example, a contact form is sent from the visitors email address, resulting in an invalid Sender address. This plugin will correct it to a valid email address. This plugin automatically corrects it. Correct envelope-from address; often forgotten, but important for deliverability. Reformat as HTML with plain text alternative; will detect the use of HTML ensures that emails are sent as HTML with a plain text alternative. Process shortcodes in your email content. UTF8 recoding, to ensure that special characters are correctly encoded in the email. Email Essentials allows for adding CSS, header, footer, and body template using filters, see below. Convert CSS to inline styles for better support in email clients SMTP configuration Send emails to multiple addressees as separate emails S/MIME signing, using a supplied certificate, to ensure the authenticity of the email. DKIM signing, and providing all information needed to set up DKIM signing for your domain. Allow redirecting emails sent to the administrator to other email addresses based on the email subject. Allow redirecting emails sent to the moderators (e.g., for comments). Keep a history of outgoing emails (debugging, cleared on deactivation) Email receipt tracking (for investigative purposes only, see GDPR note) Re-send button for failed emails Allow sending emails delayed, to prevent sending too many emails at once. (Beta feature) Important Note This tool is for users who understand email delivery. If unsure, ask for help. Under GDPR, storing and tracking emails is prohibited. The history feature is for investigative purposes only! External services Email Essentials uses one external service by default, two if you create and define your own IP services. CloudFlare DNS over HTTPS (DoH). This is used to resolve domain names to IP addresses when (for example) checking SPF or DKIM records. In theory, it is possible to use PHPs own dns_get_record function, but in practice this often fails due to server DNS-resolve misconfiguration. Using CloudFlare’s DoH service ensures reliable DNS resolution. We only send the hostname (the domain part) to CloudFlare, no other data. Explicitly, we do NOT send any other information. The plugin can use an IP-address relay service to accurately determine the sender’s IP address. This is required to accurately check that the sender’s IP address is authorized to send email for the domain (SPF check). To use this, you will need to set up your own service, see documentation on filter acato_email_essentials_ip_services. Without this service, IP detection can be inaccurate because it will use the website itself as a relay. Use of a reverse proxy, load balancer etc. can lead to incorrect IP detection.

The dual-stack service should return an IPv6 address if available, otherwise an IPv4 address, never both. You can set-up your own service like this; You will need a webserver that can run PHP, and you need a DNS service that allows you to manually add records. You will need three webspaces, for example; ipv4.myservice.com, ipv6.myservice.com and dual-stack.myservice.com. You could use the same webspace for all three, but you will still need three subdomains on the service. For the ipv4 subdomain, ONLY register an A record, pointing to the webserver’s IP address. For the ipv6 subdomain, ONLY register an AAAA record, pointing to the webserver’s IPv6 address. For the dual-stack subdomain, register both an A and an AAAA record, pointing to the webserver’s IP addresses. Create a file called index.php in each of the webspaces with the following content: php <?php header('Content-Type: text/plain'); print $_SERVER['REMOTE_ADDR']; That’s it. You can now use these services in the plugin settings like this; `php add_filter(‘acato_email_essentials_ip_services’, ‘my_custom_ip_services’); function my_custom_ip_services($services) { // Add your custom services here $services[‘ipv4’] = ‘https://ipv4.myservice.com’; $services[‘ipv6’] = ‘https://ipv6.myservice.com’; $services[‘dual-stack’] = ‘https://dual-stack.myservice.com’; return $services; } ` acato_email_essentials_ip_service Parameters: – (string) $service The URL of the IP service for the given type. – (string) $type The type of IP service (‘ipv4’, ‘ipv6’, or ‘dual-stack’).

Scripts/styles In the public/scripts and public/styles folder you find the JS and CSS files used in the plugin admin area. These files are processed with Webpack, just so it works in all recent browsers. Script is nearly identical to the source. You can find the source files in the src/scripts and src/styles folders. If you feel the need to modify these files, you can change them there, and run npm install ; npm run build to create the production files. Translation files You can use npm run i18n to generate the POT file for translation, update the PO files in the languages folder, and compile to MO/php files. This is a one-task-does-all; run it, change the translations, run it again. Done. See package.json for more details or individual commands. Tools In the tools folder you will find a script to generate DKIM keys, should you want to use DKIM signing. rename to remove the .txt extension and run it in a shell. Tools are provided as-is, without support. Use at your own risk. Read the scripts before using them. You DO NOT HAVE TO USE these scripts, you can generate DKIM keys with any tool you like.
