Deliverability – pass DKIM, SPF, DMARC & more


Of course I might be biased, but I believe this is a must-to-have plugin to protect your brand and digital identity or just to increase the chances to land in the recipient's inbox.


A must to have plugin :)


Excellent dashboard with lot of informations. I used it to fix the deliverability configuration of my website. After that, I didn't receive any complaint from my users about my emails marked as spam in their inbox.



Really effective!


Great plugin


The plugin is very well made and the code is organized and clean which is truly a plus, an added value in the sea of plugins that often bring down the performance of websites due to the poor quality of the written code.

I highly recommend trying it to all users who have problems with mail delivery from their WordPress site and who have to struggle with this annoying problem every day.



A Swiss Army Knife for optimizing email deliverability, with practical tips that guide you step-by-step through the entire process of tracking effective email delivery.


It makes checking email deliverability a breeze


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.


A standout plugin

Are your contact form emails disappearing? Customers not getting order confirmations? Password reset emails never arriving?
This plugin helps you find out why. It checks whether your domain is set up correctly for email, and then goes a step further: it sends a real test email from your site and tells you exactly what inbox providers like Gmail and Outlook see when your email arrives.
Most email tools, even ones with a “send test email” button, only confirm the message left your site by delivering it to your own inbox. But a letter mailed to your own house always arrives; that tells you nothing about whether a customer’s inbox would accept it. This plugin sends a real test email to an independent grader that reads what actually arrived, and tells you exactly what Gmail and Outlook see: whether you pass SPF, DKIM and DMARC, which service delivered it, and whether your sending address is blacklisted.
<h4>What you’ll learn</h4>
Is your domain set up for email?
<ul>
<li>Can inbox providers verify your emails are real (SPF)</li>
<li>Do your emails carry a digital signature (DKIM)</li>
<li>Are fake emails pretending to be you getting blocked (DMARC)</li>
<li>Can your domain receive email (MX records)</li>
<li>Which email service your domain uses</li>
</ul>
Do your emails actually pass security checks?
Send a real test email from your site and see what happens when it arrives:
<ul>
<li>Does it pass the sender verification check</li>
<li>Is the digital signature valid</li>
<li>Does it pass the anti-spoofing check</li>
<li>Does the sender address match your domain</li>
<li>Which service actually delivered the email (Google, SendGrid, Amazon SES, and others)</li>
</ul>
<h4>More features</h4>
<ul>
<li>Works with any email setup – whether you use an SMTP plugin (WP Mail SMTP, Post SMTP, FluentSMTP, etc.) or your host’s built-in email, this plugin tests whatever your site actually uses to send mail</li>
<li>Site Health integration – email checks appear on your WordPress Site Health screen alongside your other site diagnostics</li>
<li>Weekly monitoring – get an email notification if your domain’s email records change unexpectedly</li>
<li>Email report – send yourself a summary of the results to share with your developer or hosting provider</li>
<li>Score out of 10 – a simple score that tells you how your email setup compares to best practices</li>
</ul>
<h4>How it works</h4>
<ol>
<li>Activate the plugin and go to Tools > Does My Email Work</li>
<li>Click “Check my domain” — the plugin checks your domain’s public email records (the same records Gmail and Outlook already see when you send email)</li>
<li>The check then automatically sends a test email from your site so the service can see what inbox providers would receive</li>
<li>Get a clear report of what’s working and what needs attention</li>
</ol>
<h4>External Services</h4>
This plugin connects to the following external services to perform its diagnostic functions:
doesmyemail.work API 
Used to look up your domain’s public email records and process test email results. For the record lookup, the plugin sends your site’s domain name to this service. Email reports are generated and sent locally by the plugin – no email addresses are transmitted to this service.
When you choose to run a deep check, your site sends a test email to a unique address at doesmyemail.work, and also sends the public DNS records (SPF, DKIM, DMARC, and MX) the plugin already collected for your own domain, so the service can correlate them with the received email. The email’s routing and authentication metadata (From address, Return-Path, sending IP, detected mail service, SPF/DKIM/DMARC results, DKIM key strength, and sending-IP blacklist status) is analyzed and stored for up to 7 days, then automatically deleted. No email body content is stored or read.
<ul>
<li>Service operated by Mach10 (mach10.pro)</li>
<li><a href="https://doesmyemail.work/terms/" rel="nofollow ugc">Terms of Use</a></li>
<li><a href="https://doesmyemail.work/privacy/" rel="nofollow ugc">Privacy Policy</a></li>
</ul>
Cloudflare DNS (used by the doesmyemail.work service) 
The DNS record lookups happen on the doesmyemail.work servers, which use Cloudflare’s public resolver (1.1.1.1) to query your domain’s SPF, DKIM, DMARC, and MX records. Your WordPress site does not contact Cloudflare directly; it only connects to doesmyemail.work. No personal data beyond your domain name is involved.
