Who we are

Mission Critical Email is a Sole Proprietorship of L. Mark Stone. Our website address is: http://www.missioncriticalemail.com.

What personal data we collect and why we collect it


When visitors leave comments on the site we collect the data shown in the comments form, and also the visitor’s IP address and browser user agent string to help spam detection.

An anonymized string created from your email address (also called a hash) may be provided to the Gravatar service to see if you are using it. The Gravatar service privacy policy is available here: https://automattic.com/privacy/. After approval of your comment, your profile picture is visible to the public in the context of your comment.


If you upload images to the website, you should avoid uploading images with embedded location data (EXIF GPS) included. Visitors to the website can download and extract any location data from images on the website.

Contact forms


If you leave a comment on our site you may opt-in to saving your name, email address and website in cookies. These are for your convenience so that you do not have to fill in your details again when you leave another comment. These cookies will last for one year.

If you have an account and you log in to this site, we will set a temporary cookie to determine if your browser accepts cookies. This cookie contains no personal data and is discarded when you close your browser.

When you log in, we will also set up several cookies to save your login information and your screen display choices. Login cookies last for two days, and screen options cookies last for a year. If you select “Remember Me”, your login will persist for two weeks. If you log out of your account, the login cookies will be removed.

If you edit or publish an article, an additional cookie will be saved in your browser. This cookie includes no personal data and simply indicates the post ID of the article you just edited. It expires after 1 day.

Embedded content from other websites

Articles on this site may include embedded content (e.g. videos, images, articles, etc.). Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracing your interaction with the embedded content if you have an account and are logged in to that website.


Who we share your data with

We share your data only with those entities necessary for us to perform the services for which you provided your data in the first instance.  For example, if you place an order for Zimbra licensing, our Zimbra license aggregator and Zimbra/Synacor will be given the details necessary to complete your order.  If you purchase an in-person Training regimen, we will share your data with the facility providing the training location, the caterer providing meals, etc.  Those third-parties may in turn share your data with others so that they in turn may provide the services we collectively require of them.  The caterer for example may provide your name to the delivery service they use to deliver your sandwich to the training facility.

How long we retain your data

If you leave a comment, the comment and its metadata are retained indefinitely. This is so we can recognize and approve any follow-up comments automatically instead of holding them in a moderation queue.

For users that register on our website (if any), we also store the personal information they provide in their user profile. All users can see, edit, or delete their personal information at any time (except they cannot change their username). Website administrators can also see and edit that information.

What rights you have over your data

If you have an account on this site, or have left comments, you can request to receive an exported file of the personal data we hold about you, including any data you have provided to us. You can also request that we erase any personal data we hold about you. This does not include any data we are obliged to keep for administrative, legal, or security purposes.

Where we send your data

Visitor comments may be checked through an automated spam detection service.  Purchases and payments are completed using WooCommerce and various payment gateways, all of whom will have your data so that they may complete the service function(s) you and we require of them.

Your contact information

We do not sell nor rent your contact information. We share your contact information only as indicated elsewhere herein.

Additional information

How we protect your data

Our website is hosted by Amazon Web Services and uses encryption at rest. All traffic to and from the site is encrypted using https. We take daily backups of our website and store the backups in an encrypted, non-public Amazon S3 bucket.  The transport to Amazon S3 is also encrypted. We have monitoring and alerting in place to notify us of suspicious activity on the web site.  The website itself is derived from a WordPress image supplied by Bitnami, who have their own techniques for hardening WordPress.  Periodically, we run penetration testing scans against our website to probe for exposures.  Payments for products and services from this site are managed by WooCommerce and several payment processor gateways.  We do not store your credit card or other payment information on this web site.

What data breach procedures we have in place

Should we suffer a data breach on our web site, we would notify all registered users on the site of such breach, as well as various governmental authorities as required by law.  As this site retains only your personal information which is generally available from a variety of sources (e.g. your name), our view is that a breach of this web site will not cause any web site user any material damage.  Your credit card data, if breached by one of our third party commerce vendors, is the responsibility of those vendors as we have no visibility into their systems’ statuses.

What third parties we receive data from

This web site receives no data from third parties except for things like order and payment confirmations from our ecommerce vendors.  In the interests of full disclosure however, Mission Critical Email receives business leads from Zimbra/Synacor and other referrals periodically.

What automated decision making and/or profiling we do with user data

None whatsoever at this writing. When we start needing to sift through thousands of web site users we’ll revisit this policy at that time.
