Classify the concerns
Build a table with each concern, its category, the evidence required and the proposed action. Scope or article-type issues may call for a different journal. A design or evidence problem may require more than editing. Avoid treating all criticism as a misunderstanding.
Appeal only on a specific basis
Read the journal’s appeal rules. A concise appeal identifies a factual error or relevant procedural concern and supports it with evidence. It should not demand acceptance, attack the reviewer or present prestige and urgency as reasons to override the decision.
Revise before retargeting
Use the feedback to improve the paper even when moving to another journal. Remove old journal names, update instructions and reconcile references and file requirements. Keep changes tied to the research and do not add analyses solely to produce a preferred result.
Keep the record clear
Save the decision, reviews, revision log and final files. Ask about withdrawal or closure if the submission status is uncertain. The new journal should receive accurate declarations and any disclosures required by its policy.
