Email Subject Line

The email subject line is the summary text at the very top of an email in foreign trade business, used to quickly convey the core content of the email and directly affecting whether the customer opens it and its processing priority. Use cases include development letters, quotations, order confirmations, payment reminders, complaints, etc. Notes: The subject should be concise and specific, containing key information such as product, order number, company name; avoid all caps, exclamation marks, or spam-sensitive words; for different customers, add Re: or FW: to continue the conversation. Unlike the body and signature, the subject is the first thing the customer sees and determines the open rate. Synonymous with 'subject line', but in foreign trade it emphasizes business orientation, such as 'Quotation for 500pcs LED Lights'. A good subject can increase reply rates, while a poor one is easily ignored or misjudged as spam.
