Email subject line guide

Say why you are following up.

A useful subject line identifies the quote or the decision. It does not need fake urgency, mystery, or a sales trick.

Confirming receipt

1. Did the [job] quote reach you?
2. Your [job] quote from [business]
3. Checking delivery of quote [number]

Inviting questions

1. Any questions on the [job] quote?
2. Would you like anything clarified?
3. Scope, timing or options for [job]

Giving a truthful timing update

1. Current availability for [job]
2. Planning the [job] work
3. Timing update for quote [number]

Asking for a decision

1. Where has quote [number] landed?
2. Proceed, revisit or close?
3. Next step for the [job] quote

Closing the loop

1. Should I close quote [number]?
2. Closing the [job] quote for now
3. Final check-in on quote [number]

Subjects to avoid

“URGENT”, “last chance”, fake reply prefixes, vague “quick question” bait, or a deadline that is not real. The body and subject should agree about why you are contacting the customer.
