How do I follow up on an email when nobody has replied?
Quick answer
Reply in the original email thread so the context is easy to find. Briefly remind the recipient what you asked, make the next step clear, and give a reasonable reply-by date if timing matters. Keep the tone neutral: a missed reply does not necessarily mean a refusal. If there is no urgent deadline, send one polite follow-up after a few business days; for time-sensitive matters, follow up sooner and explain why.
The question, the details, the next step.
A practical checklist
Reply in the original thread and keep the subject line intact.
Remind the reader of the topic in one short sentence.
Ask one specific, easy-to-answer question.
Give a reply-by date only when it is useful and realistic.
Briefly explain any genuine deadline or dependency.
If there is still no response, choose one suitable next step instead of sending repeated nudges.
A few more useful answers
Should I change the subject line?
Usually, reply in the existing thread so the original context stays together. Start a new thread only if the subject has changed enough that the old one would be confusing.
Should I apologize for following up?
You do not need to apologize simply for sending a reasonable reminder. A brief, friendly opening is enough; save an apology for a specific inconvenience you caused.
How many times should I follow up?
There is no universal number. For an ordinary request, one polite reminder may be enough; if the issue matters, choose a more appropriate channel or explain the next step rather than sending repeated messages.
