How do I implement an X-header or body tag to help identify my mail for Inbox Placement in Everest?

Manuel Leyva

By implementing a matching ID (in the form of either an X-header or a body tag) in your email campaigns, you can assist Everest in uniquely identifying your campaigns.

X-header

Simply include an additional header named X-250ok-CID with a unique value for each campaign. You may need to work with your ESP to include this header.

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 -->

Creating the matching header or body tag

Some best practices for creating a unique value for your header or body tag include:

  • X-header or body tag names and values are case-sensitive.
  • Do not include any spaces in the value.
  • All 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. For example: acme_202010221045 or acme_2020-10-22-1045

Everest will look for the following matching ID types by default:

  • X-250ok-CID
  • X-rpcampaign
  • rpcampaign
  • X-PVIQ
  • X-Campaign-ID
  • X-CampaignID
  • x-job

Everest can also accept the following X-header types with a Validity Support request:

  • Tag-id
  • X-10pl8ID
  • X-Campaign
  • X-Campaign_ID
  • x-cid
  • X-eC-messenger-mid
  • X-EMarSys-Identify
  • x-jobid
  • X-Listid
  • X-MailingID
  • X-NSS

Settings

Inbox Placement includes a few configurable settings for matching ID. To change these settings, select Customize from the Overview tab. This will open the Inbox Settings slideout.

  • On the Display Preferences tab, under Inbox Tests: Default Columns, check the box beside X-Header to display the matching ID in the Inbox Tests table. Select Save.
  • On the Header Matching tab, toggle on the Copy to new child accounts switch to have child accounts inherit the matching header or body tag from the parent account.
    • To hide the matching header or body tag from child accounts, toggle on Hide from child accounts.
