"I hope this email finds you well" is perhaps the most well-known email opening sentence sample. These starting words have found their way to your inbox likely too many times. And you probably use some version of the sentence yourself almost automatically when writing emails yourself. However, there's more than meets the eye when it comes to email opening phrases.

"What opening line in an email means then?" you might ask. The opening line –  also known as the opening phrase or opening sentence – is the beginning sentence of an email right after the greeting. This first line is essential for setting the tone of the email. It also helps you to catch your recipient's attention. When deciding on the opening, the most important thing is to consider who's the recipient, what kind of relationship you have with them, and what you want to achieve with your message. You should also know that the email opening and closing phrases come in pairs – in other words, you should match how you start and end the email. 

It's good to have plenty of these phrases in your toolkit not to have to spend time thinking – or googling them – on the spot. That's why we have compiled a list of the 100 best email opening lines. These examples span across different categories such as formal, polite, professional, business, friendly. We also cover common types of mails such as cold, sales, and follow-up emails. Lastly, we have to throw a couple of curveballs with examples of informal and funny email opening phrases.

By the time you've read through this blog post, you should have a good opening line for any email right at your fingertips. If it's not on this list, you don't need it. So, instead of continuing to obsess over how do you start an opening sentence in an email, enjoy these 100 samples. 

Formal email opening lines

Formal emails are the ones you send to your professors, government officials, and at times to businesses. They are characterized by accurate grammar, punctuation, and spelling and adhere to email structure and etiquette. Many of us don't need to send formal emails that often, but these are some of the most important occasions to get the formality for the opening sentence just right. Examples of these situations include when applying for a job or trying to conduct business or handle personal matters with officials and when trying to establish a connection with a company that you are not in business with yet. Especially if the company is in an industry known to be formal and hierarchical. Below ee put together the best formal opening lines that will do the job in any such situation. So consider bookmarking this blog post for future reference.

  1. I hope this email finds you well.
  2. I hope your day so far has been pleasant.
  3. I hope you are having a wonderful day.
  4. Your prompt response is much appreciated.
  5. I am writing to you in relation to...
  6. Thank you for contacting us at <company name>
  7. Further to our earlier exchange...
  8. I am extending a hand for partnership…
  9. Allow me to introduce myself.
  10. It is great to hear from you.

Polite email openings

There are many shades of politeness, but when it comes to emails, you should try to come off as polite no matter what. The best way to be safe than sorry is to try to put yourself in the recipient's shoes and try to think about how they perceive your message and its first phrase. Being respectful and considerate, however, doesn't have to mean being formal. In fact, formalities can come off as stiff and make you seem uneasy to approach when not constituting an official or important occasion. Our advice is not to get hung up on finding a polite opening to your emails. Just follow good manners and write like you wish to be addressed if the situation were the other way around. The best email opening sentences for polite emails include the following examples. When in doubt, use one of these, and you can't go wrong.

  1. I hope this email finds you well.
  2. I hope your week has been great so far.
  3. Good morning/afternoon/evening.
  4. I hope your week started well.
  5. Thank you for the timely response.
  6. Thank you for getting in touch with...
  7. I'd be eager to get your advice on...
  8. I'm writing to...
  9. Allow me to introduce myself briefly.
  10. It's great to hear from you.

Professional email openings

Opening a professional email can be tricky. It's challenging to navigate various interpersonal relationships we all have at the office and with external stakeholders to land on the best way to open a professional email as the email's first sentence can be anything from formal to friendly. One practical strategy is to use 'mirroring'.  It refers to matching your opening line (as well as other conventions and the language) with whatever the recipient has used in their previous conversation with you. This is not always possible, and the rule of thumb is to err on the more side of things to start the email and new relationship on the right foot. Once you get to know the person, it becomes easier to adjust the tone of your emails accordingly, including just the right first words. Here are some professional email opening sentence samples that will make the decision easier for you.

  2. I hope you are having a great week.
  3. I hope you are having a great day.
  4. Thank you for reaching out to us.
  5. Thank you for the prompt response.
  6. I could use your advice on...
  7. I'm contacting you about…
  8. To follow up on my previous email...
  9. Allow me to briefly introduce myself.
  10. It's is good to hear from you.

Similarly, they are crucial for keeping existing customers, partners and vendors engaged. Your approach to business email openings should follow the same rules and conventions as with other professional emails. However, business etiquette today is more liberal than it used to be. This means you can take more liberties with the business email opening lines and phrases. The expectation to this might be when you are in business with government or city officials. It's also good to note that business email etiquette differs from country to country. So you should do your due diligence before embarking on a new business relationship with companies or people from different parts of the world. You might be surprised by how formal some cultures are.
