Industry Context And Next Action
Subject
Start here: {{engagement_name}} onboardingHi {{first_name}},
Welcome to the {{engagement_name}} engagement with {{agency_name}}. The signed scope begins {{contract_start_date}}, and the first planned deliverable is {{first_deliverable}} by {{target_date}}, subject to the dependencies below.
Please complete the secure checklist at {{onboarding_link}} by {{client_due_date}}. It covers {{required_inputs}}. Do not send passwords, customer exports, API keys, or other sensitive access by email; use {{secure_access_method}}.
Your agency owner is {{account_owner}}. Please confirm {{client_owner}} as the client-side approver, or reply with the correct person. The working cadence is {{meeting_cadence}}, approvals follow {{approval_process}}, and urgent delivery issues use {{escalation_path}}.
If a dependency will be late or the scope summary at {{scope_link}} is wrong, reply now so we can revise the delivery plan rather than silently miss a date.

Why This Email Works
Personalization Notes
- Populate deliverables and dates from the executed scope.
- Use a secure delegated-access process rather than shared credentials.
- Name both agency and client-side decision owners.
Platform Setup Steps
Trigger
A retainer agreement is executed, billing prerequisites are satisfied, and an account owner is assigned.
Segment
Newly activated retainer engagements with executed scope, satisfied billing prerequisites, and assigned delivery ownership.
Delay
Within one business hour of engagement activation.
Reply owner: Assigned account owner accountable for onboarding completeness, secure access, scope clarification, and delivery handoff.
- Verify executed scope, activation, billing prerequisite, owners, and target dates.
- Create a least-privilege secure-access checklist and map every dependency to an owner.
- Send once, track checklist completion, and escalate missing or disputed inputs before delivery work begins.
Stop conditions
- Stop on contract reversal, billing hold, duplicate engagement, security hold, or invalid recipient authorization.
- Stop reminders when all required inputs are complete or an owner opens a manual exception.
- Recalculate target dates when a documented dependency changes.
Subject Line Variations
- Start here: {{engagement_name}} onboarding
Clarity-first control tied to the exact business event.
- {{engagement_name}} owners and onboarding checklist
Alternative emphasizing the decision context.
- Your first steps with {{agency_name}}
Alternative for a recipient already familiar with the engagement.
Mistakes To Avoid
- Asking the client to email account passwords
It creates an avoidable security and offboarding risk.
Use instead: Use delegated access or the approved secure credential process.
- Starting with a vague welcome and no owners
Dependencies become invisible and deadlines drift.
Use instead: Name owners, due dates, approval mechanics, and escalation.
Sequence Placement
Use once at client onboarding after commercial activation. Checklist completion enters delivery; scope, security, or billing exceptions pause the engagement and move to a named human owner.
