You can optionally enable the HTML2Header feature, to instruct SmartRelay to automatically add the following special headers to email messages only:
X-Clab-SmartRelay-DeliveryIdSee Managing deliveries by type and category and Delivery identifier, label and category.
X-Clab-SmartRelay-DeliveryLabelSee Managing deliveries by type and category and Delivery identifier, label and category.
X-Clab-SmartRelay-ExternalIdSee Adding your own information and External identifier and description.
X-Clab-SmartRelay-ExternalDescSee Adding your own information and External identifier and description.
X-Clab-SmartRelay-PrimaryKeySee Storing recipient addresses in a user database and Primary key.
X-Clab-SmartRelay-Recipient-See Storing additional recipient attributes and Store recipient attributes.
As a result, you do not need to add the headers yourself to each individual message.
HTML2Header must be configured when SmartRelay is set up, to enable it to be used. See Setting up SmartRelay for more details. Please get in touch with your usual contact at Contactlab, such as your project manager, account manager or Contactlab customer care for more information.
See HTML2Header for more details about its use.
