A day in the life:

Power Digital is looking for a hands-on Email Migration & MarTech Consultant to own the full lifecycle of email platform migrations from technical infrastructure and ESP onboarding to integration architecture, data migration and deliverability configuration.

You will serve as the subject matter expert and project owner for client email migrations from platforms like Salesforce Marketing Cloud, HubSpot, Iterable, Braze, Mailchimp, ActiveCampaign, Drip, and others to Klaviyo managing everything from DNS/domain configuration and DKIM/SPF/DMARC setup to integration builds, identity resolution, list migrations, automation architecture, cutover sequencing and handoff.

This includes every phase of the migration engagement end-to-end: discovery, technical build, QA, go-live, and client handoff. The right candidate thrives in complexity, moves with urgency, and knows how to translate technical requirements into clear client deliverables.

Responsibilities:

End-to-End Email & SMS Migration Ownership

Own the full project lifecycle for email platform migrations from discovery through go-live and post migration QA

Lead client kick-offs, migration timelines, stakeholder communications and milestone tracking across concurrent projects

Serve as the point of contact for all technical migration questions from account teams and clients

Document migration decisions, integration specs, and handoff notes in a repeatable, scalable format

Pre-Migration Audit & Discovery

Current ESP audit: document all active flows, campaign cadences, segments, suppression lists, custom fields, and data schema from the source platform

Contact database audit: total addressable list size, engagement health, bounce/spam complaint history, hard suppression list, and consent/opt-in source documentation

Tech stack mapping: inventory every tool connected to the current ESP (eComm platform, CRM, loyalty, helpdesk, reviews, POS, CDP) before migration begins

Deliverability baseline analysis: pull sender reputation data from the legacy platform (Google Postmaster, SNDS, blacklist checks) to understand what is being inherited

Source Platform Offboarding

Export all contacts, custom properties and segments from the legacy platform in correct format for destination ingestion

Document legacy flow logic before the migration: triggers, filters, time delays, conditional splits, A/B test configurations

Extract historical performance data (open/click benchmarks) to inform Klaviyo warming strategy and baseline benchmarking

Coordinate legacy platform subscription/contract timing against Klaviyo go-live to prevent dual-billing data gaps

Define and execute legacy flow deactivation sequencing to eliminate risk of duplicate sends or missed sends during cutover

Klaviyo Account Governance & Setup

Define organization-level account structure: single account vs. multi-brand/multi-account setup, sub-account architecture

Configure user roles and permissions: internal client users, agency access tiers, admin vs. manager vs. viewer

Create and document API keys: private/public keys, scoped access per integration and key ownership registry

Advise on billing tier selection: contact tier, SMS credit planning, and overage risk management

Define and implement External ID / unique identifier strategy across all connected systems

Install and validate the Klaviyo JS snippet for onsite tracking: Active on Site events, browse abandonment, and onsite behavior

SDK setup consultation where applicable (mobile app push notification integration)

Set up and verify profiles, from addresses, reply-to routing, and compliance/governance settings

Technical Infrastructure & Email Configuration

Configure and validate all email sending infrastructure, including:

DNS records, SSL certificates, and full domain authentication setup

DKIM, SPF, and DMARC record configuration and validation

Sending domain setup, subdomain delegation, and CNAME configuration

Branded tracking link setup (custom click-tracking domains)

Dedicated vs. shared IP pool evaluation and configuration

Conduct pre-send technical audits and inbox placement seed tests before first live send

Validate DMARC reporting is active and routing correctly post-configuration

Identity Resolution & Profile Merging

Define the External ID / unique identifier strategy across all connected systems (Shopify customer ID, CRM ID, email, phone)

Design merge rules for duplicate profiles: same email/different phone, same phone/different email, anonymous vs. identified

Validate that historical order and event data backfills attach to the correct unified profile post-migration

Coordinate identifier logic with eComm platform, CRM, and any CDP in the stack

QA identity resolution outcomes on a representative sample before full list migration

Platform Integrations & API Connections

Manage the full integration setup between ESPs and connected tech stacks, including:

Native platform integrations: Shopify, eComm-native platforms, and non-Shopify platforms

Custom API integration builds and webhook migrations

Third-party tool reconnections (reviews, loyalty, subscriptions, helpdesk, POS, etc.)

Deep link configuration and custom event setup, migration, and validation

OneTrust and consent management platform migration

Opt-in form migration and lead capture verification

Verify native event sync and validate custom event payloads post-integration

Data Migration & List Management

Own all subscriber data migrations: historical profile transfers, suppression list mapping, and compliance preservation

Manage user schema migrations and data backfills between legacy and destination platforms

Set up and validate segment/list structures to support IP warming strategy

Ensure all opt-in and consent status is correctly mapped to maintain GDPR and CAN-SPAM compliance

QA migrated data sets to verify accuracy, completeness, and field mapping

IP Warming & Deliverability Strategy

Develop and oversee IP/domain warming schedules (1–3 months of structured warming depending on engagement tier)

Build campaign warming strategies: volume ramp-up plans, engagement-based list segmentation, and send cadence mapping

Monitor sender reputation signals throughout warming: spam rates, bounce rates, inbox placement scores

Define intervention thresholds and execute deliverability remediation when reputation signals degrade

Monitor Google Postmaster Tools and Microsoft SNDS continuously during and after warming

Flow Logic Translation & Automation Architecture

Translate legacy flow/journey logic into equivalent Klaviyo automation architecture:

Trigger mapping: list-based, date-based, and event-based triggers to Klaviyo metric triggers or custom events

Conditional split reconstruction using Klaviyo segment conditions and profile properties

Time delay and time zone strategy: Klaviyo handles time zones differently from most legacy platforms

Suppression-within-flow logic: smart sending rules, mid-funnel suppression, flow filters vs. trigger filters

A/B test migration: rebuilding winner-take-all or 50/50 tests in Klaviyo’s native test environment

Build flows from scratch when legacy logic cannot be directly migrated

Oversee campaign and template builds across warming sends, flows, and acquisition programs

Set up acquisition opt-in forms and connect to relevant list/segment structures

Build custom reporting dashboards and configure reporting templates within the platform

QA Framework

Integration QA: verify all events fire correctly into Klaviyo from source (placed order, checkout started, viewed product, etc.)

Profile sync QA: confirm custom properties, consent fields, and identifiers populate correctly on test profiles

Flow QA: trigger each flow in test mode, validate rendering across email clients, confirm suppression logic holds

DNS/auth QA: MXToolbox pass, DMARC reporting active, inbox placement seed test before first live send

Post-warmup QA: monitor bounce rate, spam complaint rate, and unsubscribe rate after each warming send with documented thresholds

Data QA: spot-check migrated profiles against source records for field mapping accuracy and completeness

Cutover Plan & Go-Live Coordination

Define the exact cutover date and no-send window to prevent duplicate sends from both platforms

Execute legacy flow deactivation in the correct sequence before Klaviyo flows activate

Manage the overlap period: communicate clearly which campaigns are managed in which platform during transition

Run final pre-launch checklist sign-off across all technical, data, and flow readiness criteria

Own post-launch 30-day monitoring plan with defined escalation triggers and response protocols
