14 Professional Synonyms for “As Soon as Possible” in an Email

Expressing the need for a swift response or action is common in professional emails. However, the phrase “as soon as possible” can feel overused or vague.

This article lists 14 other ways to state urgency more clearly and appropriately, depending on your situation. Each alternative is explored with examples to help you choose the best fit for your message.

Is It Professional to Say “As Soon as Possible”?

When it comes to email communication, choosing the right words is crucial. The phrase “as soon as possible” can be considered both professional and polite, but it may lean towards being slightly informal in certain contexts. It’s a common phrase used to express urgency without coming across as too demanding. However, its appropriateness depends largely on the situation and the relationship between the sender and the recipient.

Using “as soon as possible” is most suitable when requesting something from someone with whom you have an established relationship, and there is a mutual understanding of the urgency involved. It’s less appropriate in initial communications with someone you haven’t built rapport with or in situations where a specific deadline is needed.

An example of using “as soon as possible” in an email could look like this:

Hi Emily,

I hope this email finds you well. I am writing to request your feedback on the report I sent last week. Could you please review it and provide your insights as soon as possible? Your input is very valuable to our project's success.

Looking forward to hearing from you soon.

Best regards,

Here are the pros and cons of using “as soon as possible”:


  • Conveys a sense of urgency without being overly demanding.
  • Professional and polite if used in suitable contexts.
  • Flexible, allowing the recipient some discretion on the timing.


  • Can be perceived as vague, lacking a clear deadline.
  • May come across as informal in more conservative professional settings.
  • Overuse can dilute its urgency, making it less effective over time.

Someone might consider using an alternative phrase to “as soon as possible” to avoid these drawbacks. Alternatives can provide clarity, show respect for the recipient’s time, and match the formality level of the communication setting better. Using synonyms or alternatives is also a way to diversify language and avoid repetition, making your emails more engaging and precise. Whether choosing a synonym or an alternative, the key is to match the urgency and formality of your message to the situation and audience.
