Report campaign results to your manager

Background:
Campaign (name, goal, dates, channels, budget): {{campaign}}
What success was defined as before launch: {{targets}}
Who reads this and what they care about: {{manager}}
The decision or next campaign this should inform: {{next_decision}}

The results by channel (spend, reach, clicks, leads, sales, whatever we track), with where each number comes from:
"""
{{results}}
"""

What happened during the campaign (changes we made, problems, outside events):
"""
{{context}}
"""

Task: Write a short readout of the campaign's results for my manager, under 300 words plus one table.

Use these headings:
1. Bottom line: one or two sentences on whether we hit the target, with the main number.
2. Results against target: a table with the columns Measure, Target, Actual, Difference. Add the previous comparable campaign only if the results include it.
3. What worked and what did not: two or three points each, tied to numbers.
4. Why: our best explanation, labeled "likely" or "possible", kept apart from what the numbers show.
5. Next time: three specific changes, each tied to a finding.
6. Decision needed: what I am asking for, if anything.

Rules:
- Judge the campaign against the targets set before launch. Do not swap in a different measure because it looks better.
- Show the arithmetic for any rate or cost per result you calculate, and check that the numbers add up.
- Put business results (leads, sales, revenue) ahead of reach and likes.
- Where the numbers are small, say the result points in a direction rather than proves anything.
- Report misses plainly. A manager trusts a readout that admits what did not work.

Example of a "Why" line, for form only: "Likely: the email outperformed because it went to past buyers, while the ads reached people new to us."

If a number is missing, or two sources disagree (for example the ad platform and our sales records), say so in the table rather than picking one or filling the gap.
