Fixing common Email Issues

It is very common to see issues when you rely on the standard process
to send out emails via WordPress. Emails are often rejected
or not sent at all. This can include important emails such as order
confirmations
with WooCommerce, notifications on new
user registrations, blog post and comment notifications that your
subscribers should receive. Many of these cases result in unwelcome
results ranging from a reduced blog audience to
serious issues like refund requests because your
customers have not received your order and payment confirmation. The Itthinx
Mail Queue
plugin helps to eliminate these issues.

  • E-Commerce – Assure that order and payment
    confirmations are sent with the highest priority and don’t end up in
    your customer’s spam folder.
  • Contact Forms – Make sure that you receive
    notifications, that those who try to contact you can enjoy a smooth
    form submission experience and that they receive appropriate
    confirmations.
  • First things first – Prioritize urgent and
    important emails over lower priority notifications, while making sure
    that all emails are sent out in due time.
  • Avoid being flagged as spam – Are you using
    a shared server environment to host your site? Shared servers are
    often blacklisted because some of your neighbors abuse the server to
    send out their junk emails. Instead of risking your emails being
    flagged as spam, too, use a reputable and independent SMTP server to
    send out emails.
  • Avoid congestion, delays and exceeded rate
    limits
    – When you send out large amounts of emails via your site, it
    can happen that they are delayed or rejected because you exceed rate
    limits. Internet Service Providers, on both the sending and receiving
    end, may enforce rate limits according to the service contract, trust
    level and reputation of the IPs involved. An email queue helps to
    keep the number of emails that are sent out within reasonable and
    accepted limits.

Queue

The Mail Queue gathers emails that are sent on a deferred
schedule. It allows to adjust the frequency and the number of emails
that are sent out periodically.

Determine the average throughput of the email queue and limit the number of emails
sent per hour .

  • Hosted Email : Third-party email providers
    like Gmail, MailChimp / Mandrill, MailPoet, Mailgun, … usually
    enforce certain limits to the amount of emails that you can send
    through their facilities. You can adjust the values here to assure
    that when your site tries to send emails, they will not be rejected
    by your email provider because you exceed those limits.
  • Self-hosted Email : If you are using your
    own email server, this is useful to adjust the emails sent in
    accordance with the resources that are allocated to your email
    server.
  • Blogs with many Subscribers : A particularly
    useful case for the application of the Mail Queue is when blog post
    or comment notifications are sent out to hundreds or thousands of
    subscribers at a time. WordPress with many common popular plugins
    intends to notify all those subscribers at once, failing to manage
    these large amounts of emails being sent out appropriately.
    Essentially, each time you publish a new blog post that should reach
    a large audience or when a new comment is approved on a popular post,
    your site will try to send out emails to all those people and very
    likely fail, or leave you waiting in despair, as it exceeds sensible
    limits. The Mail Queue postpones all those emails and sends them out
    gradually, providing a reliable way to have all those subscribers
    notified in due time.

The queue’s parameters determine how many emails are sent and
for how long the data is kept in the queue after they have been sent.
The system sends out a batch of emails per cycle. You determine the
time between each cycle in seconds and how many emails are sent per
cycle.

Senders

Decide how emails sent from your site are treated, based on
which component or Sender is originating them:

  • WordPress Core – Choose how emails are sent from the
    WordPress core
  • Plugins – Control how emails are sent by plugins in general
    or for a specific plugin
  • Theme – Decide how emails are sent that originate from the
    active theme, for example by its built-in contact forms and other
    functions

For each component, you can specify an Action and a Priority.
The action determines how an email sent by the component is handled
while the priority dictates which ones are handled first. Actions
include the option to send emails immediately, add them to the queue
to be sent on their turn and you can even block outgoing emails for a
component.

SMTP

Avoid problems with your WordPress site not sending emails. With
SMTP enabled and configured, emails are sent out from your site using
your SMTP email server instead of your web server.

Requirements

  • Wordpress 4.6 or higher.
    WordPress 5.x is recommended.
  • PHP 5.6 or higher.
  • MySQL 5.6 or higher.
  • Working WP-Cron
    Queue processing requires that WordPress scheduled tasks are executed
    appropriately.
  • No existing wp_mail()
    override. You must not use another plugin or a customized
    implementation that overrides the standard WordPress wp_mail()
    function as this will not be compatible and interfere with this
    plugin’s correct operation. If you have such a plugin or
    customization currently in place, disable and remove it to use Itthinx
    Mail Queue
    instead.
