<p>LogStore can be used to log (important) data from within your plugin.<br />
It provides a simple interface to log entries and a friendly administration interface for viewing and managing the log entries.</p>
<p>While LogStore can be used to log debug output or system events, it’s main intention is to log more extensive data, such as:</p>
<ul>
<li>system emails sent your users</li>
<li>data received from remote API calls</li>
</ul>
<h3>Usage</h3>
<p>To use LogStore in your plugin, add the following line to your plugin’s ‘plugins_loaded’ callback function:</p>
<pre><code>if (class_exists('LogStore')) $this->log = new LogStore('slug', __('Title'));
</code></pre>
<ul>
<li>The ‘slug’ should be a unique identifier for your logger.</li>
<li>The ‘Title’ will be the title used in menu entries, options and page titles.</li>
</ul>
<p>Once that’s done you can then start logging your data from anywhere within your plugin by using the following:</p>
<pre><code>if (!empty($this->log)) $this->log->log(__('My log message'), $my_log_data, 'status', 'tag');
</code></pre>
<ul>
<li>‘My log message.’ is any arbitrary message to describe your log entry.</li>
<li>$my_log_data is the extended data you want to log. This can be either an array or string.</li>
<li>‘status’ is one of ‘none’, ‘ok’, ‘warn’, ‘critical’ or ‘fatal’.</li>
<li>‘tag’ can be any kind of singular tag to  further classification to your log entries.add</li>
</ul>
<p>If you use LogStore in your plugin, you should check for it’s presence in</p>
<ul>
<li>your ‘plugins_loaded’ callback</li>
<li>your plugin activation callback</li>
</ul>
<p>You should either make LogStore use optional or notify the user that they need to install LogStore for your plugin to work properly.</p>
<h3>Plugin Hooks</h3>
<p>In the following hooks, <code>*myname*</code> stands for the name with which you instanciated the LogStore class.</p>
<h4>Action Hooks</h4>
<ul>
<li><code>logstore_init-*myname*</code> – runs during the execution of WP’s <code>init</code> action hook, passes a single boolean parameter indicating if logging is active or inactive for this logger</li>
</ul>
<h4>Filter Hooks</h4>
<ul>
<li><code>logstore_new_entry-*myname*</code> – runs during the creation of a new entry, passes a single array containing all values for that entry (‘time’, ‘message’, ‘data’, ‘status’ and ‘tag’)</li>
<li><code>logstore_entry-*myname*</code> – runs before displaying an entry on screen, passes a single array containting all values for the entry (‘time’, ‘message’, ‘data’, ‘status’ and ‘tag’)</li>
<li><code>logstore_format_entry_data-*myname*</code> – runs before displaying the formatted data on screen, passes the formatted data as string</li>
</ul>
<h3>Further Notes</h3>
<p>Please note that the ‘bulk actions’ in the log viewer are currently not<br />
working.</p>

<p>WP Mail Logging is the most popular plugin for logging emails sent from your WordPress site. Simply activate it and it will work immediately, no extra configuration is needed.</p>
<h3>Are your WordPress emails not being sent or delivered?</h3>
<p>Use this plugin to log all outgoing emails from your WordPress site. If there are any errors when sending the email from your site, our email logs will catch that error and display it to you.</p>
<p>This will allow you to debug and fix your email sending issue.</p>
<h3>Did a client not receive your email?</h3>
<p>Our email logs allow you to resend any email that was sent from your site. No more lost emails!</p>
<h3>Do you just want to keep a record of all emails sent from your site?</h3>
<p>By default, WordPress and your web host do not log, store or keep track of emails sent from your website.</p>
<p>This plugin will allow you to do just that. Our email logs will store every email that is sent from your WordPress site.</p>
<p>You can search and view a particular email log, inspect its content or attachments, and even resend that email.</p>
<h3>What email information is logged?</h3>
<p>All emails sent from your WordPress site are logged. And here is the information that is stored:</p>
<ul>
<li>Email Subject</li>
<li>Email Content (HTML or text)</li>
<li>Email Attachments</li>
<li>Email Headers (to, from, reply-to, cc, bcc, …)</li>
<li>Error Message (in case there was an error while attempting to send the email)</li>
<li>IP Address of originating server (can be enabled in the settings)</li>
<li>Date and Time of the email</li>
<li>Receiver (the TO email address)</li>
</ul>
<h3>Why are my logged emails still not delivered to the inbox?</h3>
<p>There are a lot of steps that emails have to make in order to be delivered to the recipient’s inbox.</p>
<p>When your WordPress site sends an email, there’s no guarantee it will be delivered.</p>
<p>This is what the email’s journey looks like:</p>
<ol>
<li>WordPress creates an email</li>
<li>WordPress passes the email to your website host and that email gets logged by our plugin</li>
<li>The host server takes the email and sends it (SMTP or Mail Transfer Agent)</li>
<li>Recipient server receives or blocks the email</li>
<li>If the email is accepted, the spam filter decides if it goes to the inbox or the spam folder</li>
<li>Recipients see the email and might open it.</li>
</ol>
<p>This plugin does not track delivery after step 2.</p>
<p>If you have deliverability issues, we suggest installing the <a href="https://wordpress.org/plugins/wp-mail-smtp/" rel="ugc">WP Mail SMTP</a> plugin.</p>
<p>WP Mail SMTP fixes WordPress email deliverability problems, you can choose between 12 email providers (Gmail, Outlook, SendLayer, Mailgun, …) to resolve your email sending issue and it’s super easy to set up. WP Mail SMTP is trusted by more than 3 million websites.</p>

WP Mail Logging

Great plugin


Very easy to moving from local server to live site


moving from local server to live


Love this plugin!  Acts as a great debugging tool when outgoing SMTP is not working (seen often on VPS hosted instances without something like WP SMTP configured).  


Great debugging tool!


Nothing really more to write. I've been using the plugin for quite some time and haven't experienced any unexpected behavior.


Works seamlessly right after activation

Works well


Very useful seeing what should have gone out and figure out if there's something wrong with my mail server.


Helps keep my sanity


Sending email from WP can be problematic when the provider has a poor mailing service. This plugin is perfect to monitor the email activity, find possible problems, resend emails.



I'm using it simple and very complex sites. It's particularly useful to track emails sent by plugins (ecommerce, form managers and so on): most of the time, when there are problems, they can be solved looking at the log.



IMHO every site should have it.


A must have


Love this plugin. Save me from huge lose. 


Little but huge impact. Very helpfull

Log, view, and resend all emails sent from your WordPress site. Great for resolving email sending issues or keeping a copy for auditing.
