Salesforce Marketing Cloud Email Studio

Overview

Salesforce Marketing Cloud Email Studio is the email marketing component of Salesforce Marketing Cloud, responsible for sending promotional and transactional emails and measuring their performance. On websites, its presence manifests through tracking pixels embedded in emails (which fire when recipients open messages) and campaign attribution scripts on landing pages that track conversions from email clicks. It was formerly known as ExactTarget before Salesforce's acquisition.

What This Script Does

Email Studio's web-facing components operate across two surfaces: tracking pixels within sent emails and attribution scripts on the website.

In emails:

• Open tracking pixels (1x1 transparent images) hosted on Salesforce domains (typically *.sfmc-content.com or *.exacttarget.com) fire when a recipient views the email, recording the open event, timestamp, IP address, and user agent.
• Link tracking wraps all URLs in the email with redirect URLs through Salesforce's click-tracking infrastructure, recording which links each recipient clicks.

On the website:

• Landing page scripts capture campaign attribution when visitors arrive from email links, associating the web session with the specific email send, subscriber, and campaign.
• Form tracking captures lead information submitted on campaign landing pages, feeding it back into Marketing Cloud's subscriber database.
• Conversion tracking scripts fire on thank-you or confirmation pages to attribute conversions (purchases, sign-ups, downloads) to the originating email campaign.

Key cookies set:

• Campaign attribution cookies linking the web session to the email campaign ID and subscriber ID. Expiry varies but is typically session-scoped or short-duration (24 hours to 30 days).
• Standard Marketing Cloud tracking cookies (_sfmc_id, _et_id) may also be present if the broader Marketing Cloud tracking is deployed alongside Email Studio.

Consent & Compliance

Email Studio operates in the marketing category. Its web-facing scripts exist to measure the performance of marketing email campaigns and attribute conversions.

Under the GDPR, email tracking pixels process personal data — recipient IP addresses, device information, and behavioral data (open/click events) tied to identifiable email subscribers. The email tracking is governed by the consent obtained when the subscriber opted in to the mailing list, but this consent should specifically cover tracking and profiling, not just receiving emails. On the website side, campaign attribution cookies require separate consent.

The ePrivacy Directive requires consent for cookies set on the website for email campaign attribution. These cookies serve marketing measurement purposes and are not strictly necessary for the website's core functionality.

Under CCPA/CPRA, the email engagement data (opens, clicks) and website conversion attribution data constitute personal information used for marketing purposes. Since this data typically stays within the Salesforce ecosystem for the organization's own marketing analysis, it is less likely to constitute a "sale" or "sharing" unless the data is combined with advertising platform integrations.

Should You Block This Without Consent?

Yes. Email Studio's web-facing scripts set marketing attribution cookies and track campaign conversions. These are not essential for the website to function and require consent. The email-side tracking pixels operate independently of website consent mechanisms and are governed by the subscriber's email marketing consent.
