Project email that can be found a year later
At 18:30 the superintendent replies to a thread titled "Re: tomorrow". His email confirms a sleeve location on level 3, asks about Thursday's crane lift and mentions a damaged stair door frame. Three topics under a subject about none of them: in six months nobody will find them.

Start every subject line with the job number, the area and the topic; keep each message to one topic; put the decision or request in the first two lines; and file it in the project, not your inbox. Email becomes the job's record whether you plan it or not; it helps only if someone can find it and read it without the thread around it. Provincial records guidance agrees: Prince Edward Island's archives ask for a specific, descriptive subject line, one topic per email and a new thread when the topic changes, and Saskatchewan's says to keep email with the other records of the same activity.
Write it to be found
- Build the subject line the same way every time: job number, area, topic and, where it helps, the kind of message — "3207 | L2 lounge | ceiling height | decision".
- Keep to one topic. When a reply turns to something new, start a new email.
- Put the point first: the decision, who made it and when, or the request and the date you need an answer.
- Name documents exactly, by sheet and revision or by number, and attach them.
- Name each person's action, and copy only people who need to know.
- File it in the project the same day, sent and received.
Confirming a spoken instruction has its own method in verbal instructions in writing; some messages should not be email at all: see choosing the channel.
Common mistakes
- Replying in an old thread, burying a new decision under the old subject.
- Subject lines like "Question", "Update" or "Tomorrow".
- Forwarding a long thread with "see below" and no summary.
- Keeping the only copy in one person's mailbox.

Check your understanding
A thread titled "3207 | L3 corridor | sprinkler heads" turns to the corridor's paint colour. What do you do, and why?
