Please do not hesitate to contact us

You will almost always find this phrase at the very end of an email, a formal letter, or even a customer support chat transcript. It acts as a 'closer.' After you’ve provided information, sent a document, or answered a specific request, you throw this in to show you’re still available. For example, if you just sent a contract to a new client, you’d end with: If you have any questions regarding the terms, please do not hesitate to contact us. It’s like the period at the end of a very polite sentence. You can also use it in person during a formal meeting or a Zoom call. As you’re wrapping up, you might say, 'If anything else comes up later today, please don't hesitate to reach out.' Notice how people sometimes swap contact us for reach out—it’s the same vibe but feels a tiny bit more modern. Just remember to keep the to in there; leaving it out is a classic mistake that makes the sentence fall apart.

This phrase is the king of the 'Formal' and 'Professional' categories. You’ll see it in bank emails, insurance documents, and job offer letters. It’s what we call 'Standard Business English.' It’s not quite 'Old English' level formal, but it’s definitely not something you’d say to your best friend when planning a movie night. On a scale of 1 to 10, where 1 is a 'Hey!' and 10 is a letter to a monarch, this phrase sits comfortably at an 8. If you use it in a very casual setting—like texting a group chat about pizza—it will sound like a joke. Imagine saying to your roommate, 'If you require further pepperoni, please do not hesitate to contact us.' They’d probably think you’ve spent too much time at the office! However, in a professional Slack channel or a LinkedIn message to a recruiter, it’s perfectly appropriate. It shows you know the 'rules' of professional etiquette.

You’ll encounter this everywhere once you start looking. Customer support bots on websites like Amazon or Airbnb often use a version of this. 'Your refund has been processed. Please do not hesitate to contact us if the funds do not appear in five days.' It’s also very common in the travel industry. If you book a hotel through Booking.com, your confirmation email likely ends with this invitation. In the world of online learning, your tutor might send a message after a difficult lesson saying, 'That was a tough topic today! Please do not hesitate to contact us if you need extra practice materials.' Even in TikTok or Instagram captions for small businesses, you’ll see 'Check out our new drop! For custom orders, please do not hesitate to contact us via DM.' It’s the universal signal that the 'Help' desk is open for business.

Use this phrase whenever you want to sound professional and helpful at the same time. It’s perfect for the end of a job application follow-up or when sending a project update to your boss. It’s particularly useful when you’ve given someone a lot of information and you suspect they might have questions. If you’re a freelancer sending an invoice, adding this at the bottom shows you’re easy to work with and transparent. It’s also a great way to show 'Proactive Service.' If you’re an Uber driver and a passenger leaves something behind, a message saying 'I've found your keys; please do not hesitate to contact us to arrange a return' sounds much more reassuring than a blunt 'I have your keys.' It’s about building trust and showing that you value the relationship.

Avoid this phrase in highly emotional or deeply personal situations. If a friend is going through a breakup, saying Please do not hesitate to contact us sounds cold and robotic—almost like you’re a lawyer they hired to handle their heart. In that case, 'I'm here for you' or 'Call me anytime' is much better. Also, don't use it if you actually *are* too busy to help. If you tell someone not to hesitate and then you don't reply for three weeks, the phrase backfires and makes you look disorganized. Lastly, avoid it in very casual text-speak. If you’re using emojis and 'u' instead of 'you,' this phrase will look like it was copy-pasted from a different planet. It needs to match the environment around it. If the vibe is 'Chill,' keep your closing chill too.

The most frequent error is forgetting the word to. Many people say ✗ Please do not hesitate contact us, which sounds like you’re giving a command to someone named 'Hesitate.' Another common slip-up is using about or for instead of to. For example, ✗ Please do not hesitate for contacting us is grammatically incorrect. You also want to make sure you use us or me correctly. If you are a solo freelancer, contact me is better; if you represent a company, contact us is the standard. Some people also try to make it 'more' formal by saying ✗ Please do not have hesitation to contact us, which is just clunky and sounds like you're trying too hard. Stick to the classic version—it’s a classic for a reason! It’s like a well-tailored suit; it never goes out of style.

Depending on how much 'corporate' flavor you want, you can swap things around. A very popular modern version is Feel free to reach out. This is like the business-casual version of our phrase—it’s what you wear on a 'Casual Friday.' Another one is Let us know if you have any questions. This is very common in the tech world and on platforms like Discord or Slack. If you want to be even more formal, you could say Should you require any further assistance, please let us know. The 'Should you' at the beginning is very fancy! In the UK, you might hear Please don't hesitate to get in touch, which feels a bit warmer. If you’re texting, you might just say Let me know if u need anything!. The key is to match the variation to the person you are talking to.

Is this phrase too old-fashioned? Not at all! While it is a bit formal, it remains the standard in 90% of professional emails worldwide. Can I use it in a text message? Yes, but only if the text is for business purposes, like an automated delivery update. Does hesitate mean I'm calling them slow? No, it's actually the opposite! You're telling them *not* to worry about being slow or annoying. Should I use me or us? Use us if you are part of a team or representing a business, and me if you are the only point of contact. Is it okay to use it with a boss? Absolutely, it shows you are professional and ready to support them. What if I don't want them to contact me? Then definitely do not use this phrase! Use something more final like 'Thanks for your time.'
