1Understand it in 30 seconds: what's new

Shopify's account component(the sign-in UI on the storefront) can now showan opt-in checkbox for marketing subscription below the email field.
A customer who checks it and completes sign-in isadded to the email marketing subscriber list.

Before: sign-in only

The account component was only a UI for entering an email address and signing in. Capturing subscriptions required a separate path (checkout, a separate form, etc.).

Going forward: sign-in + opt-in

A checkbox sits right below the email field, so you cancapture subscriptions within the existing sign-in flow. The setting uses the same option shared with checkout.

2How it works: the flow from sign-in to list enrollment

Customer account component email Subscribe Sign in Shopify Detect sign-in completion + read the opt-in value Email subscriber list subscriber A subscriber B + NEW customer Register as a subscriber
Key point: registration happens "when sign-in completes". Simply checking the box does not register them; they are added to the subscriber list at the moment the sign-in process completes (original article: added to your email marketing subscriber list when they complete signing in).

3Related setting: shared with Checkout's subscription setting

Settings > Checkout Marketing opt-in Default subscription opt-in setting Uses the same setting value Checkout opt-in Subscribe Account component Subscribe (NEW) ↑ Shares the same ON/OFF
The setting is in Settings > Checkout > Marketing opt-in of the same setting value, is used. You don't need to keep separate settings in two places—checkout and sign-in.

ItemBefore (previous)After (now)
Checkbox in the sign-in UI None Shown directly below the email field
Timing of adding to the subscriber list A separate flow such as checkout When sign-in completes

Impact on customers who only want to sign in — Unchanged from before if the box is left unchecked
API / Webhook specifications — Not documented

5Setup steps (3 steps)

1

Open Settings > Checkout

In the Shopify admin, open Checkout from Settings.

2

Review/change Marketing opt-in

Here you decide whether the box is checked or unchecked by default.

3

Install the account component

Once you add the account component menu to your online store, it is reflected automatically.

Reference documentation: "Adding an account component menu to your online store" and "Collecting customer contact information" (links in the article). For specific theme setup steps, see Shopify Help.

6Five key points developers should know

1. The UI position is fixed "below the email field"

The article explicitly states it is below the email field , and the placement is not a spec that themes can freely move—it is the component's default behavior.

the same settings

2. Shares setting values with Checkout

There is no independent opt-in setting for sign-in; it referencesSettings > Checkout > Marketing opt-in directly. Changing it on the checkout side also carries over to the sign-in side.

3. Registration happens "upon sign-in completion"

Simply checking the box does not subscribe the customer; they are added to the subscriber listat the point the sign-in process is completed. Sessions abandoned partway through are not subscribed.

ON OFF

4. The default state follows the admin settings

Whether the box is shown pre-checked or unchecked is determined by the Marketing opt-in setting under Settings > Checkout. It must align with regional consent requirements.

API ?

5. No mention of API / Webhook / custom field specifications

The article covers only the admin operational flow. How this is reflected in the Customer object's email_marketing_consent fields, or the differences in Webhook events, isnot describedin this article. If you build CDP / MA tool integrations, separate verification is required.

7Three use cases you can apply to your business

USE CASE 1

Accelerate "list growth" through the member login flow

Challenge
Many customers register or sign in, but the email marketing subscriber list and the account holder list diverge, so the deliverable audience doesn't grow.
Action
Enable the opt-in checkbox in the account component. Operate it with wording and default values unified with the Checkout subscription flow.
Impact
The subscriber list expands with the sign-in flow left unchanged. A larger deliverable audience → a lift in CRM revenue.
Technical note
The UI position is fixed directly below the email field. When implementing, confirm the prerequisite that the account component menu is placed in the theme.
Marketing opt-in Checkout Account Component
USE CASE 2

Centralize consent-collection governance in "a single setting"

Challenge
Consent wording and default values vary across checkout / account / separate forms, making them costly to explain in legal and privacy audits.
Action
Since the account component shares Checkout's opt-in setting, switch to operating with Settings > Checkout > Marketing opt-in as the "single source of truth."
Impact
Consent policy changes can be made in one place, reducing governance / audit costs. Switching default values to match regional requirements can also be centralized.
Technical note
If you collect opt-ins separately via a custom form, sort out the overlap with this feature and the consistency of double opt-in before switching.
subscriber count
USE CASE 3

Measure the "subscription acquisition rate via sign-in" and turn it into a strategy

Challenge
It's hard to see which channels drive subscriber acquisition, so there's no basis for deciding whether to revamp the sign-in UI.
What to do
Turn opt-in ON and run it for a set period to measure how much your list grows via sign-in. Later, layer on A/B tests that vary the wording and default value.
Impact
You can show in numbers how much the sign-in flow contributes to subscriber acquisition. This can also be repurposed to forecast growth of your sendable audience.
Technical notes
This article doesn't mention any API for measuring by channel, so separating out traffic sources requires operational workarounds on the store side, such as segmenting by date plus channel.
