Testing Environment 

Does Ongage have any type of testing environment for the purposes of testing changes without interfering with production lists, campaigns and events? 

  • For this purpose you can create a Test List whereby all contacts there will be for the testing purposes.
  • You can also use this list for your Ongage API testing.
  • Moreover can create one or more General Users with limited access to this Test List only.

See our Getting Started Guide → Import Contacts, Add Lists, Migrate into Ongage for more info about adding lists.

Email Message ID

  • Email messages are the contents (typically HTML email messages) you send to the contacts in your list. 
  • Every email message has a unique ID that you can find in the ID column on the Content → Email Messages page of the list.
  • It's helpful to use this unique ID when communicating with support.

Campaign ID aka CID 

  • The CID is a unique ID associated with each campaign in the Ongage platform.
  • You can find the CID in the Campaigns → Campaigns Overview page, under the CID column (the CID can found on other screens as well such as the Analytics → Aggregate report).
  • It's helpful to use this unique ID when communicating with support.

ESP Connection ID aka ECID

  • ECID (short for ESP Connection ID): is the unique number ID given to each ESP connection in your Vendor Settings → My Connections dashboard
  • It's helpful to use this unique ID when communicating with support. 
  • You'll also need this ECID if you're doing a Transactional mailing via the API.


  • The ESP ID (esp_id) is an internal unique Ongage ID that Ongage has assigned to each SMTP / ESP / SMS vendor.
  • You can find ESP ID by going to Vendors Settings → ESP/SMTP Vendors, and clicking on the name of anyone of the vendors there, e.g.,
  • Typically the ESP ID has no usage (except maybe in some unique API use-case), and is just an internal ID Ongage uses to uniquely identify different vendors.
    • It does appear in the Contact Activity Report (see Analytics), though in the future it will be replaced with the name of the vendor instead of the ID.
