 * Hello,
 * I’ve been consistently getting the following PHP notice when using `wp_mail()`
   with this plugin installed.
 *     ```wp-block-code
       PHP Notice: Function wpdb::prepare was called incorrectly. Unsupported value type (array). …for more information. (This message was added in version 4.8.2.) in /wp-includes/functions.php on line 5905
       ```
   
 * It looks like it’s coming from wpdb::insert() via /post-smtp/Postman/PostmanEmailLogs.
   php(261) – here’s the error trace I put into place:
 *     ```wp-block-code
       #0 /wp-includes/class-wpdb.php(2689): wpdb->prepare()
       #1 /wp-includes/class-wpdb.php(2601): wpdb->_insert_replace_helper()
       #2 /wp-content/plugins/post-smtp/Postman/PostmanEmailLogs.php(261): wpdb->insert()
       #3 /wp-content/plugins/post-smtp/Postman/Postman-Email-Log/PostmanEmailLogService.php(186): PostmanEmailLogs->save()
       #4 /wp-content/plugins/post-smtp/Postman/Postman-Email-Log/PostmanEmailLogService.php(113): PostmanEmailLogService->writeToEmailLog()
       #5 /wp-content/plugins/post-smtp/Postman/Postman-Email-Log/PostmanEmailLogService.php(85): PostmanEmailLogService->writeSuccessLog()
       #6 /wp-includes/class-wp-hook.php(310): PostmanEmailLogService->write_success_log()
       #7 /wp-includes/class-wp-hook.php(334): WP_Hook->apply_filters()
       #8 /wp-includes/plugin.php(517): WP_Hook->do_action()
       #9 /wp-content/plugins/post-smtp/Postman/PostmanWpMail.php(262): do_action()
       #10 /wp-content/plugins/post-smtp/Postman/PostmanWpMail.php(60): PostmanWpMail->sendMessage()
       #11 /wp-content/plugins/post-smtp/Postman/PostmanWpMailBinder.php(121): PostmanWpMail->send()
       ```
