For communication to be successful, the message must flow both ways without any interruption – but you already knew that.

Even though we’re talking about virtual communication at the moment, you still need to include a certain dose of politeness when composing an email for your colleague, boss, or employee. 

During your business communication, you will often need to compose thank you notes and emails. And even when the conversation doesn’t end the way you envisioned it, you still have to give thanks to the person on the other side.

I’m here to make your job a lot easier and save you the time you would spend thinking of an effective thank you email subject line that will start off your conversation properly.

Get your e-notes ready because I’ll be sharing ways to write effective thank you emails that will impress your reader.

Is Sending A Thank You Email Necessary?

Let’s start off with some convincing statistics. 

You’d be surprised to find out that 94% of HR managers claim that it is advisable to send a thank you email after a job interview, a successful or unsuccessful business transaction, and so on.

Just to be clear, it’s not mandatory – no one will force you to write such emails, and it’s not in the rule book, but it’s highly recommended.

Giving your sincere thanks, even via emails, says a lot about you, your manners, and the way you treat your superiors, colleagues, and acquaintances.

But just sending a thank you email is not all there is to it.

The media you use to send it also carries some importance. 

Namely, if it was a business transaction you were taking part in, and it didn’t go as you imagined – you can’t just send a thank you message on Instagram and call it a day.

You need to be professional.

According to research and HR managers, these are the parameters that show how acceptable it is to send thank you emails via different means of communication.

Let’s take a quick look at what the numbers have to say.

  • Email – 94%
  • Handwritten note – 86%
  • Phone call – 56%
  • Social media – 7%
  • Text message – 5%

Before I go on, let me comment on this quickly.

As you can see, email is the most common but even more importantly, the most adequate means of communication when it comes to thank-you notes. Sending these types of notes via social media or a text message is in most cases considered very unprofessional.

When do you write thank you emails?

Here are scenarios when it’s appropriate to write a thank you note:

  • After someone helps you for a job search
  • After you’re done with a job interview
  • When a customer makes a purchase
  • Stating your general appreciation for something/someone 
  • When someone provides you with a networking contact

Still not sure how to write an appropriate thank you email?

It’s super easy. You can just follow the steps I’ve outlined, and you’ll have an effective thank you email that’ll put a smile on your recipient’s face in just minutes.

  • Pick Your Means Of Contact

The first step in compiling a thank you email is picking the appropriate means of contact.

As you could see from past examples, email is still the most effective – especially when it comes to business deals. You shouldn’t rely too much on phone calls. There is a chance that someone will not answer right away, you will give up after a few attempts and the intention of thanking someone will go into oblivion.

  • Choose Your Recipients

Sending an email is always direct, even when it’s just a thank you note.

Sometimes you will be asked to address only one person you know by name, and sometimes you will have to address the entire team or organization. Either way, this is an indispensable part.

For example:

Dear [ recipient’s name ], / Greetings, / Hi everyone,

  • Be Direct, But Polite

Although you are writing a thank you note, that doesn’t mean you shouldn’t keep it professional.

Even thank you emails require a dose of professionalism – especially if it was the first successful sale and you are expected to continue doing business with the person / organization on the other side.

Also, thank you notes are advisable after someone helped you in finding a job or gave a memorable reference.

For example, you can start off your email with:

I hope all is well. I just wanted to say thank you for the support you provided me with in my career search.

[ Continue with details ] . The information you gave me made all the difference and helped me get the position I was going for. 

I am happy to report that I’ve [ mention your achievement ] .

Again, thank you for all of your efforts. I really appreciate it!

  • Take Care Of Important Details

Grammar and spelling check!

Before you click on “send”, make sure that you’ve gone through your email a couple of times and corrected all your mistakes. Make sure you appropriately address the recipient, that you have correctly written the details for which you are grateful, etc.

  • Sign Off 

And lastly, signing off.

There are many ways to close your email. Here are some recommended examples when it comes to thank you emails:

  • Gratefully,
  • Kind regards,
  • Best wishes,
  • Many thanks,
  • Thank you again,
  • With gratitude,
  • Respectfully,
  • Thanks a bunch,
  • Sincerely,
  • Warm wishes,
