## Àpèjúwe

This email validation and blocklist plugin makes it easy to set up email blocklists
and mx checking on WordPress email functions to reduce bounce rates and unwanted
signups.

### Features

**Email blocklist** Ìtumọ̀ Yorùbá: – This plugin gives you granular control of a
blocklist that allows you to stop users from using email addresses that you donÌtumọ̀
Yorùbá: ’t want them to. Whether you want to block a specific email address or an
entire domain, this plugin can handle it.

The plugin also handles prioritising specificity over generalisations, meaning you
can block a domain while allowing a specific email address by simply setting the
appropriate entries in the blocklist.

**MX record checking** Ìtumọ̀ Yorùbá: – Mx records tell the Internet where to send
email for a domain, if mx records for a domain youÌtumọ̀ Yorùbá: ’re sending email
to doesnÌtumọ̀ Yorùbá: ’t exist, itÌtumọ̀ Yorùbá: ’s generally not worth trying 
and can result in a hard bounce that affects your sender reputation.

**External list synchronisation** Ìtumọ̀ Yorùbá: – There are plenty of lists that
you might want to update your blocklist synchronised to, whether thatÌtumọ̀ Yorùbá:’
s a list of disposable email domains or a curated list that your agency maintains.
Set the url and let the plugin keep your blocklist in sync by setting up a scheduled
job.

Something being blocked by the external list when you donÌtumọ̀ Yorùbá: ’t want 
it to be? Just set the domain to be whitelisted, and the synchronisation wonÌtumọ̀
Yorùbá: ’t touch it again, even if itÌtumọ̀ Yorùbá: ’s in the list.

**Logging** Ìtumọ̀ Yorùbá: – Knowing when an email has been blocked is just as important
as knowing that emails are being blocked and stopped from being sent. You can choose
to log emails that are sent from WordPress and the logs will tell you what failed
on which email addresses to help you address issues. The plugin will log all recipients(
those contained in the To, Cc and Bcc fields), the checks and results performed 
on each recipient, and the subject line of the email.

**Works with multisite** Ìtumọ̀ Yorùbá: – The plugin is designed to work with multisite,
by correctly actioning multisite level actions (activate/deactivate/uninstall etc).
This does mean however that all multisite sites are independent of each other. For
large multisite installations, using wp-cli or other tools may be required to prevent
timeouts as the plugin utilise custom database tables that are created on activation.

**Define your settings in wp-config.php** Ìtumọ̀ Yorùbá: – Run a site for someone
else or just need to manage your settings for the plugin through something other
than the WordPress dashboard? A number of settings can be set by [defining constants in your wp-config.php file](https://capably-digital.com/plugins/email-validation-tools/constants/).
If you donÌtumọ̀ Yorùbá: ’t get a value quite right, weÌtumọ̀ Yorùbá: ’ll provide
a notice for users with the “manage_options” permission on single site installations
and “manage_site_options” on multisite.

**Expandability** Ìtumọ̀ Yorùbá: – If the plugin doesnÌtumọ̀ Yorùbá: ’t do what 
youÌtumọ̀ Yorùbá: ’re looking for exactly, it also exposes a [number of hooks](https://capably-digital.com/plugins/email-validation-tools/hooks/)
that allow you to change the plugins behaviour to suite your needs. The plugin also
exposes API endpoints to allow remote management of the blocklist.

### Compatibility

Because our plugin hooks into core WordPress functions, it has extremely wide compatibility,
itÌtumọ̀ Yorùbá: ’s been tested and appears to work with Core WordPress functions,
Elementor Forms (via a hook that enables the is_email filter), Contact Form 7, Newsletter,
Noptin, WooCommerce, Easy Digital Downloads, LearnPress, bbPress, and BuddyPress.
ItÌtumọ̀ Yorùbá: ’s also likely to work with many more that use the filters that
WordPress provides.

The notable exception that was found during testing was MailPoet, which does not
use the standard filters provided by WordPress, and doesnÌtumọ̀ Yorùbá: ’t appear
to offer a hook that enables integration.

### Source Code

The plugin is the source code, there is no (public) repository that contains the“
raw” version. What you see is what we work with to create the plugin.

## Ìgbéwọlẹ̀

 1. Download the .zip file and upload it to your site, or install from the “Plugins”
    page in your WordPress dashboard.
 2. Enable the plugin in the “Plugins” section of your WordPress dashboard
 3. By default only mx checking will be performed at mail-time as the blocklist is 
    set up but empty.
 4. Head to the “Email Validation” section of your WordPress side bar to configure 
    the pluginÌtumọ̀ Yorùbá: ’s blocklist and other settings.

## FAQ

### How does a blocklist and/or mx record checking reduce bounce rates?

Bounce rates are an indicator of how an SMTP service sees you as a customer, and
if your bounce rates get too high it can impact both your inbox placement and whether
a provider is willing to continue doing business with you. For the most part, SMTP
services donÌtumọ̀ Yorùbá: ’t do their own checks to make sure that youÌtumọ̀ Yorùbá:’
re sending to an email address that makes sense beyond the basics, and will treat
an email address where there are no email servers (mx records) as a “hard bounce”
that dings you in your providers eyes. Similarly, a blocklist lets you block particular
domains and email addresses (for example those that are known to be disposable email
addresses) to avoid sending to email addresses that are unlikely to remain monitored.

### What happens when an email or domain is blocked?

It depends at which stage the block takes place:

 * During email validity checks (hooking into the WordPress is_email filter) the
   user will be presented with a message advising their email address isnÌtumọ̀ 
   Yorùbá: ’t valid, the same as they would if they used a nonsensical address.
 * During email sending (hooking into the WordPress pre_wp_mail filter) the email
   will not be sent.

You can decide which checks take place when in the settings page in your WP Admin,
by default the blocklist is checked in both of the situations above, and checks 
to ensure valid mx records are performed on email sending.

### Do email entries override domain entries?

Yes, they do. Since email address entries are more specific than domains, those 
take priority where they exist. This allows you to do things like block an entire
domain, but allow a specific email address.

### Can I manually override a domain from an external list?

Yes, you can. Simply add the instruction you want the plugin to follow in the Manage
Domains page of the pluginÌtumọ̀ Yorùbá: ’s settings, and it will honour that instruction
because the implementation for syncing external lists is designed not to override
your choices.

### Does syncing an external list mean my database will keep growing?

No, the implementation for syncing external lists cleans up after itself by removing
domains that were added that are no longer part of the list, to keep things manageable.

### Will checking MX records slow down my site?

That depends on your setup. If youÌtumọ̀ Yorùbá: ’re using a mailing plugin that
relegates email sending to WP-Cron, then itÌtumọ̀ Yorùbá: ’s unlikely to (but it
also depends on where the plugin does this relegation in the process), otherwise,
the mx check takes place during the page processing, which can take a moment, but
generally not more than sending the email itself.

### I have an issue thatÌtumọ̀ Yorùbá: ’s not listed, what do I do?

While weÌtumọ̀ Yorùbá: ’ve tried to test as much as possible, itÌtumọ̀ Yorùbá: ’
s always possible that a new plugin has bugs (whether thatÌtumọ̀ Yorùbá: ’s a missed
error or something specific to your environment). If you have an issue we recommend
enabling logging, which will generally tell you why the plugin blocked an email.
If you still have issues, head to the [plugin support forum](https://wordpress.org/support/plugin/capably-digital-email-validation/)
and leave a message, and weÌtumọ̀ Yorùbá: ’ll do our best to work with you to solve
any issues you have.

DonÌtumọ̀ Yorùbá: ’t forget, that if youÌtumọ̀ Yorùbá: ’re having issues, others
may too, so let us know!
