What the compared capabilities mean

Open pixel

An individualized remote image, loaded when the message is opened. The capability says the platform knows how to insert one — not that it does so on every email.

Click tracking

The rewriting of links to count clicks. A treatment of the same nature as the pixel — individualized tracking — and enabled by default on every sending platform.

Exclusion by campaign

Sending a given campaign without inserting the open pixel.

Exclusion by contact

Removing the pixel for certain recipients only, while still sending them the message.

Consent — absence means no pixel

Without recorded consent, the platform knows how to send the message without a pixel. It's the capability that decides.

Native consent collection

The platform collects consent to tracking through its own means — a form, a preference centre, a revocation link — and applies it to the email. Exposing an attribute that the brand fills in elsewhere doesn't count as collecting it.

Tracking anonymization

A mode advertised as “identifier-free.” It only holds if it stops loading an individualized image: Article 82 concerns access to the terminal, not what is collected afterwards.

Traceable choice

A field or mechanism that durably retains the contact's choice on open tracking, and that can be exported.

List-Unsubscribe

The header that declares an unsubscribe address or page to the email client.

RFC 8058 — one click

One-click unsubscribing, handled by the email client without opening a page.

Preferences page

A page where the recipient chooses what they receive, instead of cutting everything off or keeping it all.

Transactional exceptions

Excluding a service flow from commercial unsubscribe rules, without taking it out of the logs.

DKIM

The signing of the message by the sending domain. It's this signature that carries the selector we use to recognize the platform.

SPF

The authorization, published in DNS, for this platform to send on behalf of the domain.

DMARC

The alignment of the previous two with the domain visible to the recipient. The policy remains under the brand's control.

Sending domain

A brand's own domain in place of the platform's. Once configured, only the DKIM selector still gives the tool away.

Tracking domain

A brand's own CNAME for rewritten links and the pixel. Without it, every click from the recipient names the platform.

Logging

A dated, exportable log of setting changes. It's what answers the question the day someone asks since when.

API

A documented public interface, including for contact attributes — without which a recorded choice stays locked inside the tool.

Consent history

The retention of a contact's successive consent states, and their export.

Granularity of settings

The level at which a setting applies: account, list, campaign, contact.

The five states

Yes, No, Partially, Not verified — nobody has checked yet — and Not applicable, when the question does not arise for this service.
