Sailthru: Including Identifiers in Links

You may want to pass a unique Sailthru identifier from links within your email to help enable cross-channel identity resolution. This will help Lytics identify users across data streams and merge their email and web activity.

The easiest way to pass a unique identifier from Sailthru click-through links into Lytics is to modify your email template to include a hashed email in each URL in the email being sent.


The Lytics JavaScript Tag must be installed on your site, and an import will need to be active with userId set for import (default state). In addition, a line of LQL (Lytics Query Language) will need to be added to the Sailthru query in order to map the hashed email field to the user's profile. For assistance contact your Lytics representative or Lytics support.

For example:

qs(url, "email_hash") as hashed_email SHORTDESC "Hashed Email"

Add encrypted email to Sailthru links

  1. Ensure the Lytics Sailthru import Hash Algorithm option is set to 'SHA-256' (default).

  2. Log in to Sailthru and navigate to Communications > Templates then select your email template.

  3. Select the Advanced tab.

  4. Copy email_hash={sha256(email)} into the Auto-Append Link Parameters field. Screenshot 2018-11-28 Template Editor

Now all email clicks will pass the encrypted SHA256 email to your website when users click the links, and Lytics will map the encrypted email to the user's profile.
