By adding a header to your email campaign, you can assist Inbox in uniquely identifying your campaign. Simply include an additional header named X-250ok-CID with a unique value for each campaign.
X-250ok-CID body tag:
For users who don’t have the ability to inject a header into outgoing email, we offer the ability to embed a tag in the HTML body of your email. Simply include, anywhere in the body, a tag that looks like this:
<!-- X-250ok-CID: uniqueid1234567890 -->
Some best practices for creating a unique value for your header include:
- Do not include any spaces in the value.
- All X-250ok-CID values should be unique PER CAMPAIGN.
- Prefix your campaign value with a company name or nickname.
- Consider including a timestamp in your value to help ensure uniqueness.
If you include this header with your campaigns, you will be able to query our API with it, and it will be displayed throughout the Inbox reports. Child accounts inherit x-headers from their parent account so feel free to contact 250ok to have your parent account configured to accept the header types below.
For new parent accounts and their associated child accounts, (Note: This does not apply to some older parent accounts) 250ok will look for the following header types by default:
250ok can also accept the following x-header types.
Open your 250ok Settings Menu and select “Contact Support” under Help Center or contact 250ok Support to configure your Inbox account.
