Rules for B2B sales follow-up subject lines

• Never send 'just following up' — it's the most ignored subject in B2B.
• Reply within the same thread when you can; a fresh subject can reset context.
• Give a reason to respond: a resource, a question, a next step.
• One clear ask per email; multiple asks kill reply rates.
