How to Write the Best-Performing Follow-up Emails?

In this fast-moving time, it would have been hundreds of times with you, like you cannot revert to somebody’s sole email or the actual content on time,, or somebody else would have taken a long time to revert to you. So here comes the rule of sending follow-ups to your colleagues, managers, contacts, or anybody from whom you expect a response. Especially for business owners, when you feel like your initial mail content has been ignored, sending a follow-up message will surely help you get your conversation back on track.

However, writing a follow-up mail after receiving no response from the initial contact is a tricky task, but you still have to send it. So let us move ahead in this detailed guide and understand how you can write a follow-up mail after getting no response from the client, along with some examples and templates of the same. Stay tuned with us till the end, as you will surely enjoy reading this blog!

What is a follow-up email?

Simply put, an effective follow-up mail is a kind of e-message sent to a recipient you have already contacted once. There can be many reasons when it comes to the need to send a follow-up message, like:

  • For just alerting the prospects to the previously sent e-message content.
  • Request some information or a response.
  • Reminds the recipient about the date or time frames for a vital quick meeting request or event.

So basically, the main purpose of follow-ups is to act as a reminder for a sole mail already sent. It is not to start any new conversations; it is just to reinvigorate the previous communication and generate a response to it. 

The most effective and efficient follow-up mails are simple, sweet, professional, short, and, most importantly, just to the point. Because once, a US-based team analyzed about 2 billion emails and found that most contacts tend to skim over lengthy ones. And if the mails were short and easy to read, 50% of them would receive responses in just 30–40 minutes.

Experts have also proved that e-messages sent during the morning are most likely to receive responses. However, mails sent during the afternoon or the weekend have significantly fewer chances of getting early responses.

Why do people not respond to emails on time?

Have you ever tried just to give a thought to this matter? Why don't people respond to outreach messages immediately?

The marketing experts have proved in a study that there are five core reasons why people ignore electronic messages:

  • The effort or time involved in handling that particular is more, and the recipient does not have that much time.
  • The identity of the sender of the sole e-mail
  • The number of recipients or prospects in the sender's list is not good.
  • The workload of the prospects
  • And lastly, it mainly depends upon the urgency and priority of that particular outreach message.

How long should you wait before sending the follow-ups?

The answer here is "not so long."

Research shows that most mails are opened on the same business day they are sent, and if the recipient is interested, they also tend to respond on the same business day. That simply means it is pretty easy to understand that if somebody does not revert to your outreach message the same business day, they are either uninterested or will not respond.

 So, as a generic rule, waiting for 2-3 days is a reasonable amount of time to be given to the email recipient before sending the gentle follow-ups. 

What is the best way to write a follow-up mail?

Always remember, it is very important to test your follow-up message subject line while sending the mails. It has been shown in a survey that 47% of mail openers report their mails as spam only based on the subject line alone. 

So it is correctly said that those tiny little sentences can even break or make you. Apart from the subject lines, while writing these follow-up messages, pay attention to the mail content format, mainly the email's starting and closing. Just keep it short and straightforward.

Now that you understand how important it is to send follow-ups to the recipient and after how long that should be sent. So, let us move ahead in the guide and learn how to write these reminder messages. So the perfect format for the same is divided into five parts:

  1. The subject line of an outreach mail. 
  2. Greeting
  3. The mail body
  4. Closing
  5. The email signatures

The subject line of an email

An executive coach, Rebecca Zucker, advised in the Harvard Business Review that keeping the outreach message subject line short, simple, and sweet is essential. She says that almost 47% of the emails are discarded because of having lame or lousy subject or introductory lines. So, make sure you are not making this kind of mistake.

Writing a follow-up message that brings back results is too challenging. So mainly, we should aim to keep the subject lines to five words or under. The reason behind this word limit is that 56% of the mails are being read by people on their mobile devices, where it seems like the fewer the words, the better it is

So below are just some follow-up message subject line examples:

  • Follow-up: email sent on xxxxxxxxxxxxxxxxxxxxxxxxxx
  • Response required: Email sent on xxxxxxxxxxxxxxxxxxxxxxxxxx
  • A gentle Reminder to register for xxxxxxxxxxxxxxxxxxxxxxxxxxx
  • Reminder about a networking event
  • Thank you for our initial meeting.
  • It'd be great to hear back from you.

All these introductory lines are entirely different from each other and have different purposes for sending them. The most important thing you should remember while writing your follow-up mail content is that you should never be funny in your subject line because people can find it offensive. So below are some cold mail subject line examples to make you understand things much better:

  • Did you receive my last mail?
  • Why didn’t you respond to my mail?
  • I am waiting for your response.
  • Just checking in.


Being from a professional background, you should always focus on being formal while sending initial or follow-up messages. That means you should always use professional greetings in your follow-up mails until you have a personal connection with the sole email recipient. So you can refer to the most commonly used tool, SmartLead AI,  how to write an effective email. 

The email body

A follow-up message is a formal and fast way of raising awareness of the outreach messages  you have sent to your prospects.

So while writing the body of your follow-up mail, you need to provide some well-crafted email content from the previous sole mail. Or else you can try to follow the below method to make sure that the previous email at least has the information the prospects need to know:

  • Forward the original email content itself to the prospects again.
  • Paste the previous well-crafted email in your respective mail.
  • Provide some crucial pointers from the initial messages as reminders.
  • Give some external links to any kind of important information.


In the mail body, when you have politely requested a response to your email, you should still let the recipient know how you will use their response further and what you will do if the recipient does not respond again.

Leaving your prospects without confusion about your next steps is essential.

The signatures

A professional and polite sign-off is mandatory for the follow-ups. So if you don’t know how to end the content correctly, you can refer to the SmartLead AI tool that will help generate email signatures.

Mistakes to avoid while sending the follow-up emails

So, after going through the format of the follow-up mails, you should also be aware of the mistakes you must avoid. People tend to make four common mistakes while sending follow-ups.

Mistake #1:

Starting the follow-ups with "just following up" and sending that email adds no value to the prospects. These days, each of us is busy in our lives, so nobody wants to receive mails that can’t justify their email topic and show the next course of action required or any quick question too. 

Mistake # 2:

Use the word "follow up" in the subject line itself. People will likely ignore and spam these kinds of emails. Because such messages give customers the feeling that you are trying to blame them for something. Instead, you should write a subject line relevant to the purpose of sending that follow-up message.


Mistake #3:

Do not follow up quickly. Waiting for just 2-3 days is more than sufficient. Not waiting too long ensures that the topic of your initial well-crafted email will be fresh in the recipient's mind. However, people tend to forget about the initial messages themselves if they send follow-ups after too long. So it is better to wait for a good 3 days and then send a polite reminder email to either request a response or provide a timeline in which they can respond.

Mistake #4

If you forget about including the call to action from the prospects' end, So, while writing the follow-ups, you must mention in them what exactly you want the recipient to do after reading your well-crafted mail. For example, do you want them to reply to your email? Do you expect a call back from them? Or do you just need to get some forms filled out? So you should never forget about this.
