Subscriptions

CheckTLS.com offers three levels of access to our site: Individual, Professional, and Corporate. All subscriptions have a money back guarantee: if you are not satisfied we will refund your money.

Subscription Levels

  • Individual
    • Our mission is to make secure email better: used correctly, in more places, more reliably. We make our two most popular test tools TestReceiver and TestSender available at no charge.
    • This allows you to test basic secure email operation for your servers and for domains to which you send email. All tests at this level are run sequentially in a queue to control use of servers and bandwidth.
    • Cost: free, no signup or login required!
  • Professional
    • Run all our tests, and run them much faster.
    • Upload multiple addresses and test them all at once with Batch Test.
    • Save and run multiple Sender tests with your own unlimited use TestSender pass-code.
    • Test an email system "End To End" using both TestReceiver and TestSender at once. See Thru Test on the Batch Test page.
    • Test email systems that "Require TLS" for certain trading partners. See Certain Domains Must Use TLS.
    • Test custom/private email systems that are hidden from the Internet, and/or run on non-standard TCP ports, and/or require authentication. See Full Parameters on the TestReceiver page.
    • Cost: $10/mo or $100/yr
  • Corporate
    • Seamlessly integrate our tools into existing systems and standard operations. Rather than develop and maintain tests, scripts, and processes, use ours as if they were your own.
    • Schedule Batch Tests to run automatically at intervals ranging from monthly to hourly. Since Batch Test can only notify you on errors, this lets you effectively monitor your systems.
    • Makes Batch Test results available as a web service easily interfaced with your monitoring/notification system. You can open tickets and use your normal troubleshooting, escalation procedures, and problem tracking.
    • Multiple logins to CheckTLS.com so other people can verify email addresses, maintain batch test lists, or monitor a system.
    • Cost: $25/mo or $250/yr
  • ForceTLS
    • Complete, real-time security verification of every email as it is sent.

Payment Options

Our focus is email security. It is not security for credit card and bank account information. We leave that to PayPal.
Please use billing(at)CheckTLS.com for all billing communications.

We offer three ways to pay: Subscription, Company PO, or Credit Card


  • PayPal Subscription

    The best way to use CheckTLS.com is with a pay-as-you-go subscription. PayPal manages your subscription and protects your payment information. You only pay as long as you are using CheckTLS.
    Signing up is a two-step process:

    • Use this button to enter the UserCode and Password you would like to use to access CheckTLS: Subscribe.
      Since this is only protecting your ability to run tests and does not protect your payment info, we suggest using your most common email address as your UserCode and something you won't forget for the password. We also ask for your name and another email address.
    • Choose your Subscription Level.
      We will transfer you to PayPal to complete the financial part of the transaction. When you finish with PayPal, you will be returned to our site where you can login with your new UserCode and immediately access all the privileges that go with it.

    Note that a PayPal subscription does require creating an account on PayPal. See Credit Card below to purchase without a PayPal account.


  • Company Purchase Order

    Companies that cannot use PayPal can work directly with our billing department with a Quote / PO / Invoice process. Unlike a PayPal subscription, this process must be repeated every year. The Quote / PO / Invoice process is a three-step process:

    • Use this button to generate a CheckTLS Quote for a one year subscription to CheckTLS.com: Get A Quote.
    • Send us a company Purchase Order referencing this Quote (email is good).
    • We will setup your subscription and send you an invoice (by email). CheckTLS can only accept payment in USD.

    As long as payment is received in a timely manner, the subscription will remain valid.

    While we will try to contact you before your subscription expires, CheckTLS.com cannot guarantee that your subscription will not expire without notice; therefore we recommend the PayPal subscription option above.


  • Credit Card

    Subscriptions to CheckTLS.com can be purchased with a credit card without creating an account on PayPal. The process is the same two steps as a PayPal Subscription (above) but must be repeated every year because PayPal does not store any payment information since you do not create a PayPal account:

    • Use this button to enter the UserCode and Password you would like to use to access CheckTLS: Buy Now.
      Since this is only protecting your ability to run tests and does not protect your payment info, we suggest using your most common email address as your UserCode and something you won't forget for the password. We also ask for your name and another email address.
    • Choose your Subscription Level.
      We will transfer you to PayPal to complete the financial part of the transaction. When you finish with PayPal, you will be returned to our site where you can login with your new UserCode and immediately access all the privileges that go with it.

Cancelling a PayPal Subscription Unsubscribe.

There are two ways to cancel your subscription to CheckTLS.com: One, you can cancel directly from our site in one easy step. We verify you really want to cancel, update our records, and then pass you to PayPal to cancel your payment.

You can also cancel at any time by going directly to PayPal. Login to your PayPal account, choose your CheckTLS payment, and cancel it. Since we do not have your payment information, we cannot charge you once you tell PayPal to stop.

Changing a PayPal Subscription

Because we use PayPal to protect our subscriber's payment information, changing your subscription on CheckTLS.com is a manual process.

To change your subscription, either in level (Professional, Corporate) or period (monthly, yearly), first cancel your existing subscription, then re-subscribe at the new level. If you have more than a month left on your old subscription, contact us at subscriptions(at)CheckTLS.com, and we will issue a credit via PayPal to your account or credit card.

Or you can request your credit first, before you re-subscribe. Cancel your subscription and email us, wait for the credit to appear, and then re-subscribe at the new level. This will result in an interruption in your CheckTLS.com service.
