Simply and directly asking about the request, or a question related to the request can make the respondent look at your original request and do the required work before you get a reply.

Ask a question

In follow up emails, the phrase “Per my last email,” can be avoided, as it can sound a bit rude.

The way we follow up on email

Just point directly at the request, by circling, pointing or directing clearly to the original request.

The Direct Approach

You can restate your original request, summarizing in one or two sentences.If your original email was never read, this will be beneficial again.

Restate the request

If you catch hold of the person you require follow up from, you can politely remind them about the email.If necessary, pick up the phone and call to ask, just saying that you were about to type a follow-up email so thought of calling and asking first.

Talk on the phone

This might sound a bit intrusive but it is an effective tactic to drop by their workstation/cabin and ask about the response or action.Whether you call, drop by or talk in the lobby, do send an email to keep a record of the discussion.

Drop in and ask

Well, here we are again. You need something from a colleague, but haven't received a response yet. It's time to follow up. You pull up the thread, click "Reply," and have the urge to start typing, "Do you have those answers for me? Per my last email, the deadline was this morning."
