 * Hi Guys,
 * I recently received an email message regarding your upcoming TLS configuration
   changes for API access.
 * I’m using the Postmark for WordPress plugin along with Gravity Forms to process
   form notifications.
 * Is there anything I need to do on my end to accommodate these changes?
 * Thanks.

 * Hi, Phil!
 * TLS v1.1 or higher will be required for the Postmark API after the configuration
   changes are made. We recommend using TLS v1.2.
 * You can check your TLS v1.2 compatibility using [this plugin](https://wordpress.org/plugins/tls-1-2-compatibility-test/).
 * After installing the plugin, change the dropdown for ‘Select API Endpoint’ to
   _How’s My SSL?_ and run the test.
 * If compatibility with TLS v1.2 is not detected, contact your server host or make
   the necessary upgrades to support TLS v1.1 or v1.2.
 * TLS 1.2 requires:
    - PHP 5.5.19 or higher (looks like you meet this already from your comment)
    - cURL 7.34.0 or higher
    - OpenSSL 1.0.1 or higher
 * I hope this helps! Let us know if you need any more help with checking your compatibility
   for the upcoming TLS changes.
 * Best,
 * Patrick

 * Thanks very much for your help and guidance Patrick.
