## Description

Our Deliverability Plugin for WordPress allows you to easily authenticate emails
generated from your website with a DKIM signature.

But our Deliverability Plugin does much more than that! In fact, it’s packed with
incredible email security and email deliverability features such as:

 * SPF authentication check, monitor and troubleshoot
 * DKIM authentication implementation, check, monitor and troubleshoot
 * DMARC authentication check, monitor and troubleshoot

It’s always a good practice to authenticate your domain, but if your domain has 
a DMARC record and your website runs on WordPress you almost certainly need this
plugin.

The Deliverability plugin will take your Email Deliverability to a whole new level.

This plugin is designed and written by experts and is easy to use and understand.

It reduces security risk by checking for shortcomings in your email setup, and by
implementing and enforcing the latest recommended Email security practices and techniques.

Fully compatible with Contact-Form 7, WPForms, BuddyPress, WP Mail SMTP and more.

## FAQ

### What is this plugin about?

This plugin allows to monitor and improve your Email Authentication. It provides
unique features such as DKIM signing and Deliverability scoring that are a game 
changer for any internet marketer.

### My domain has a DMARC. Do I need this?

Absolutely YES. If you have a DMARC you MUST DKIM-sign your WordPress emails using
our Plugin or they will fail DMARC.

### My domain doesn’t have a DMARC. Do I need this?

Do you want to monitor and improve your Email Deliverability? If the answer is Yes,
then you need this plugin even if your domain doesn’t have a DMARC record.

### Do I need any technical knowledge to set up and use the plugin?

No technical expertise is required to use our plugin. It’s designed to be user-friendly,
with intuitive settings and clear documentation to guide you through the setup process.
Only a very basic understanding of DNS is required to publish the provided DKIM 
key.

### How does your plugin help with SPF, DKIM, and DMARC authentication?

Our plugin simplifies the process of implementing and managing SPF, DKIM, and DMARC
authentication for your WordPress website. It automatically generates the necessary
DNS records and provides easy-to-understand settings for monitoring and troubleshooting
authentication issues.

### What happens if I already have DKIM, SPF, or DMARC records set up?

You will still need this plugin. Every mail stream must have its own DKIM or it 
won’t be authenticated. On top of this, our plugin will seamlessly integrate with
your existing configuration allowing you to monitor your authentication setup within
the plugin interface.

### Can I use the plugin with other email marketing or contact form plugins?

Absolutely! Our plugin is fully compatible with popular email marketing and contact
form plugins like Contact Form 7, WPForms, BuddyPress, and WP Mail SMTP, ensuring
that all outgoing emails from your website are authenticated. Please reach out in
case you encounter any compatibility issue and we’ll look into it.

### Does the plugin require any ongoing maintenance or updates?

Our plugin is regularly updated to ensure compatibility with the latest WordPress
versions and email authentication standards. Once installed and configured, it requires
minimal maintenance, giving you peace of mind that your email authentication is 
always up to date.

Unfortunate I do not recieve any email for verifications my account. Tried on different
installations and different emails.

### 󠀁[Excellent plugin …](https://wordpress.org/support/topic/excellent-plugin-9390/)󠁿

 [nigelpentland](https://profiles.wordpress.org/nigelpentland/) Du 19, 2024

I’m seriously impressed with this plugin. Easy to configure, works a treat and succeeds
in what it sets out to do, i.e. DKIM signing email. Thank you so much. It’s so good
and as a free plugin I’m almost embarrassed to ask, but I will. It creates auth0_session_0
cookies and I’m happy to accept that. The only trouble is I try to keep my website
as secure as possible and when I check my security headers I see auth0_session_0
cookies don’t use the secure flag. Would it be possible to have the option for these
cookies to use the secure flag?

A plugin like this was much needed in the WordPress repository. It’s a great tool
to improve your email deliverability. Overall, a very helpful plugin.

I added DKIM, but it does not recognize it, I tried few times, and waited weeks,
nothing, I contacted developer via email, no reply, will change review if developer
will reply, my email redasgms@gmail.com

 [edigi](https://profiles.wordpress.org/edigi/) Meurth 18, 2024

I really like this plugin. It does exactly what I needed and you get a deliverability
score depending on the settings that are established in the backend. The only downside,
is that it took me some external research to get the correct setup for DMARC (the
ones provided, where not precise enough). Once I got it correctly, my website rated
100% on the deliverability score. Thanks.

### 󠀁[A standout plugin](https://wordpress.org/support/topic/a-standout-plugin/)󠁿

 [Antonino Piazza](https://profiles.wordpress.org/antpza/) Kevardhu 14, 2023

The plugin offers a straightforward and user-friendly experience. Following the 
simple instructions in the settings page, I successfully added the TXT record to
my DNS and my emails were successfully signed. I particularly appreciate the delivery
chart and the dashboard, which provide valuable insights on my email deliveries 
and how to enhance it. These features empower me to ensure a safer and more reliable
communication to my customers.
