Simple vs WP Mail Logging

Plugin homepage | Plugin author | Plus Version Simple Email Queue is a WordPress plugin that is used to pass restrictions set by your host on number of sent emails in given period. This basic free version is only useful for developers that can extend it and use it in their code. If you want to use it in full capacity, consider getting plus version. Usage First, you need to set what is maximum number of emails that can be sent in a given period. By default, it sends 10 emails in 6 minutes. This means that if you want to send 15 emails in 6 minutes, only 10 emails are sent while rest 5 emails are put in queue and sent in the next period, after 6th minute has passed. You can change this limits by using filters from you code. Filter simple_email_queue_max is used to set maximum number of emails that are sent in period. It expects positive integer to be passed. To change period length, you can use filter simple_email_queue_interval. It also expects positive integer to be passed but please take care that this number is of seconds, not minutes (for example, if your period is 30 minutes, you would pass 1800). Different hosts use different limits. Please consult your host’s documentation or support to find this out. If you want user interface in your admin area, use plus version. To use this limits, you need to use function simple_email_queue_add() instead of built-in function wp_mail(). Both accept same parameters. Emails that are sent using wp_mail() function are not sent using queue and are not counted for limits. If you want that all emails are sent using queue, even those sent using wp_mail() function, use plus version. And it’s on GitHub.

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. Are your WordPress emails not being sent or delivered? 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. This will allow you to debug and fix your email sending issue. Did a client not receive your email? Our email logs allow you to resend any email that was sent from your site. No more lost emails! Do you just want to keep a record of all emails sent from your site? By default, WordPress and your web host do not log, store or keep track of emails sent from your website. This plugin will allow you to do just that. Our email logs will store every email that is sent from your WordPress site. You can search and view a particular email log, inspect its content or attachments, and even resend that email. What email information is logged? All emails sent from your WordPress site are logged. And here is the information that is stored: Email Subject Email Content (HTML or text) Email Attachments Email Headers (to, from, reply-to, cc, bcc, …) Error Message (in case there was an error while attempting to send the email) IP Address of originating server (can be enabled in the settings) Date and Time of the email Receiver (the TO email address) Why are my logged emails still not delivered to the inbox? There are a lot of steps that emails have to make in order to be delivered to the recipient’s inbox. When your WordPress site sends an email, there’s no guarantee it will be delivered. This is what the email’s journey looks like: WordPress creates an email WordPress passes the email to your website host and that email gets logged by our plugin The host server takes the email and sends it (SMTP or Mail Transfer Agent) Recipient server receives or blocks the email If the email is accepted, the spam filter decides if it goes to the inbox or the spam folder Recipients see the email and might open it. This plugin does not track delivery after step 2. If you have deliverability issues, we suggest installing the WP Mail SMTP plugin. 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. Credits The plugin was created and launched in 2014 by Christian Zöller.
