Complaint email evidence checklist

Complaint threads often hold the clearest record of what was said and when. Capture them as chronology events and evidence files — not as arguments.

• Export or save each meaningful message with date and time visible.
• Keep the full thread order; do not drop earlier context when saving a later reply.
• Note who sent what (you vs them) in the event title: “Complaint emailed”, “Seller replied”.
• Save attachments separately and label them (invoice, photo, credit note).
• Record any promise (“we will refund by Friday”) as its own timeline entry with the date of the email.
• If you used a web chat or portal, screenshot with URL/date if shown, and describe the channel in the evidence label.
• Match amounts mentioned in emails to your invoice and bank records.
