Relevant evidence for the current detailsHi Jordan,
You asked about the current details in proposal REF-1042. This approved case study is the closest example we have: https://example.com/next-step
Why it may help:
- Similar point: the current details
- Important differences: the current details
- Work completed: the current details
- Time period: the current details
The results belong to that client and period. They do not predict what Northstar Services will achieve. Use the example only to help decide the current details.

If the example is not a fair match, we will not use it to support the recommendation.

Before You Use This Email
Why This Approach Works
Platform Setup Steps
Trigger
A proposal-stage buyer has a documented evidence question and an approved case study is materially relevant.
Segment
Proposal-stage opportunities with a documented evidence question and an approved materially relevant case study.
Delay
At least three business days after the prior proposal step, unless the buyer requested the evidence.
Reply owner: Account strategist responsible for case-study selection, claim substantiation, and proposal questions.
- Match the open decision to an approved case study and verify claim authorization.
- Document relevant similarities, material differences, scope, period, and measurement disclosure.
- Send once and route applicability questions to the strategist; stop the sequence on any response.
Stop conditions
- Stop on reply, proposal decision, revision, close request, opt-out, or active staff conversation.
- Stop if case-study approval, client authorization, or supporting evidence expires.
- Stop when material differences make the example unsuitable for the buyer's question.
Mistakes To Avoid
- Sending the biggest result instead of the most comparable case
A dramatic but irrelevant example does not answer the buyer's question.
Use instead: Select for operating and scope relevance, then name the differences.
- Repeating an unsourced metric in the email
The short message strips the number from its method and context.
Use instead: Link the approved case study and summarize comparability rather than headline performance.
