Four weeks before the Campaigns GA date of April 28, 2026, Storevine’s growth PM compiled the launch checklist to coordinate readiness across engineering, design, legal, merchant success, and marketing. The checklist reflects the unusual compliance complexity of a production email send feature . where legal sign-off is a hard blocker and DMARC/SPF/DKIM sender authentication is a technical prerequisite for inbox delivery, not a nice-to-have.
Source Notes:
CAN-SPAM Act (FTC, ftc.gov) and GDPR Article 6 (gdpr.eu) . the legal requirements that make the Legal & Compliance section items non-negotiable blockers rather than optional pre-launch review steps; any production email send without Legal sign-off creates direct regulatory exposure.
Google, “Email Sender Guidelines” (support.google.com/mail/answer/81126) and Yahoo’s sender requirements (help.yahoo.com/kb/SLN27791) . the 2024 enforcement of DKIM, SPF, and DMARC authentication as prerequisites for inbox delivery to Gmail and Yahoo accounts, which represent the majority of merchant customer inboxes, making sender authentication a launch-gate infrastructure item.
SendGrid, “IP Warm-Up Overview” (sendgrid.com/blog/warming-up-your-ip-address/) . documents the required gradual volume ramp for new dedicated sending IPs to establish sender reputation with inbox providers before full-volume merchant sends are enabled at GA.
Prompt
/launch-checklist
Feature: Campaigns v1.0 . native email marketing for Storevine merchants
Launch date: April 28, 2026
Launch type: Major Release
Launch owner: Growth PM
Key compliance and infrastructure requirements:
- Legal sign-off on CAN-SPAM + GDPR required before any production send
- DMARC/SPF/DKIM sender authentication required for Gmail/Yahoo inbox
delivery (enforced by Google and Yahoo since 2024)
- SendGrid dedicated IP warm-up plan needed before full-volume sends
- Feature flag rollout: start at 10% of merchants [fictional], scale
to 100% over 2 weeks based on send failure rates
Stakeholders:
- Engineering Lead (Platform Squad)
- Merchant Success (launch comms + support)
- Legal (CAN-SPAM/GDPR review)
- Storevine Marketing (announcement + dog-food)
Key risks from stakeholder summary:
- Legal review not started; hard gate on compliance sign-off
- Klaviyo partner team needs 48-hour advance notice before GA announcement
- Power-user merchant beta cohort expectations may exceed v1 scope
Need: full pre-launch checklist with go/no-go criteria, rollback plan,
and check-in schedule.

Events logged to the attribution events table and to a Campaigns event log for debugging
Go/No-Go Criteria
Must Have (Blockers)
Legal sign-off on CAN-SPAM compliance architecture . no production email send capability enabled without this
DMARC, SPF, and DKIM configured and verified for the Campaigns sending domain
All P1 edge cases passing in QA (per edge cases document)
Merchant Success training complete and canned responses approved

Rollback Plan
Trigger Conditions
Send failure rate exceeds 5% [fictional] over any 60-minute window after GA
A CAN-SPAM violation is reported (unsubscribe link absent or non-functional in a sent campaign)
Attribution webhook receiver failure causes more than 1,000 unprocessed events to accumulate [fictional]
A merchant data breach or unauthorized access to the subscriber data pipeline is detected
Rollback Steps
Set the Campaigns feature flag to 0% . disables the Campaigns admin entry point for all merchants within 2 minutes of the flag change; in-flight sends already submitted to SendGrid are not recalled
Post a Storevine status page update: “Campaigns is temporarily unavailable . we’re addressing an issue and will restore access shortly”
Verify that no campaigns remain queued in the SendGrid pipeline that have not yet been submitted; drain the queue or cancel pending sends as appropriate
Page the Engineering Lead and Platform Squad on-call for root cause analysis
Do not re-enable the feature flag until root cause is identified and resolved; do not set flag above 0% without Head of Product approval
Rollback Owner
Engineering Lead . reachable via on-call PagerDuty [fictional]
Rollback Time Estimate
Under 5 minutes (feature flag toggle to 0% takes effect within 2 minutes of change)

Status
Impact
EU merchant GDPR consent data model
Legal
In progress
Risk: if Legal review is not complete by Apr 14, EU merchant access is confirmed as v1.1; not a blocker for US GA
Klaviyo partner notice email
Growth PM
Scheduled for Apr 26
Risk: if not sent 48 hours before GA announcement, Klaviyo partnership team learns about Campaigns from a press release . medium partnership friction risk
Power-user merchant beta expectations
Merchant Success
Managed
Risk: discovery cohort participants have expectations from Jan interviews; Merchant Success will brief them on v1 scope at beta access (T-4 weeks) before GA
