What is Email Bounce and Why Do Emails Bounce?

When you can’t deliver an email to a server, it’s called an email bounce. The cause for the email bounce is usually communicated by the server. You, as an email marketer, don’t want to get these bounces for any reason.

When your email fails to deliver to a recipient for some reason, it is known as an email bounce. There could be a variety of causes for this, including:

•The mailbox of your intended recipient is full.

•The email address is invalid.

•Invalid email address

•Your message was blocked by spam filters.

•The email server is offline

•The DNS record is incorrect

And so forth. There are various types of email bounces, but I’ll go over seven of them and distinguish between soft and hard bounces.

There are different types of email bounces

You go to your email service provider’s website, type in the address and body, and then hit the ‘Send’ button. However, you receive an indication that your email has not been delivered.

Email bounce is a phenomenon that might put your email marketing flow off. That is why you strive to stay away from them as much as possible.

To do so, you must first comprehend all forms of email bounces in order to avoid receiving them in the future.

There are two sorts of email bounces: harsh and gentle. I’ll also assist you in learning more about them and other forms of email bounces. After that, you’ll be able to distinguish between hard and soft bounce emails. Doesn’t that sound fantastic?

Let me classify email bounces into three categories:

•Hard bounces

•Soft bounces

•General bounces

Bounces that are triggered by the server’s technical limitations are known as general bounces. You’ll start with hard and soft bounces before moving on to general bounces.

Hard Bounce (bounce_hb)

A hard bounce occurs when an email is never delivered. The best course of action is to clean the addresses that cause the hard bounce. The following are the causes of hard email bounces:

Invalid or inaccurate email address:  Within a year or two, 40% of email users change their addresses. It’s a waste of time to keep sending emails to these addresses.

Fake email address: Some people don’t want to receive emails from you, so use a fake email address. As a result, they offer you a fictitious email address in the hopes of receiving something in return.

blocked email address: When the recipient’s email server prevents your server from sending an email, this is known as a blocked email address.

How can you get rid of hard bounces? You can’t, to be honest. Maintaining a clean and healthy list is the greatest option. Here are a few things you can do to avoid hard bounces:

•Remove bounced email addresses that aren’t legitimate.

•Make it a habit to clean your lists on a regular basis.

•Segment your list to target a specific demographic.

That’s pretty much everything you can do in email marketing to avoid hard bounces.

Soft Bounce (bounce_sb)

When you can’t deliver an email right now, you’re using soft email. You don’t have to be concerned because you can quickly detect and eliminate the problems.

However, you must first comprehend the reasons behind a mild bounce:

The inbox of your intended recipient is full.

Solution: It’s only temporary, so you can send the email again. Simply try again at a different time or wait a few days.

The addressee isn’t even real.

Solution: If possible, check with that person’s additional contact information. And then try to find the person’s new address by targeting them again.

The server is currently unavailable.

Solution: wait till the server is up and running again. If you maintain your server, address the issue right now.

The size of the email exceeds the server’s capacity.

Solution: Make sure your email isn’t too long and doesn’t include any significant attachments.

The recipient’s auto-reply.

Solution: wait for the recipient of your email to open it.

Bounced Email Blacklist

As you can see, soft email bounces are simple to deal with.

85 percent of the 350 billion emails sent every day are deemed spam. And this happens when your emails are blocked or marked as spam by an email server. There could be a variety of reasons for this.

Spam filters are automated systems that detect and block spam messages. Your email marketing campaign may be mistaken for spam by these spam filters.

The following are the causes of blacklist email bounces:

•Bounce rates are high.

•Harassing content 

•Complaints about spam

•An immediate increase in the number of emails sent or the size of the email list

What you can do to avoid email bounces from blacklists:

Let’s move on to other forms of email bounces.

Transient Bounce (bounce_tr)

The term “transient bounce” refers to the fact that the server is still attempting to deliver your email. It’s quite normal, and you shouldn’t be concerned.

Even if the issue continues, it normally goes away within 24 hours.

Solution: Check to see if the receiver has already received emails from other individuals, and chances are they will accept yours as well.

Change of Address (bounce_ac)

It occurs when a recipient’s email address changes and an auto-reply is sent with the new address.

What you can do to help: Incorporate the new email address into your contact list. Also, use our free Email Validator to see if the new email address is legitimate. Also, find out about email validation best practices.

You may segment your list and send a re-engagement message to everyone who has updated their email address.

DNS Errors (bounce.df)

The transitory bounce is an email bounce triggered by a DNS fault. The following are some of the possible reasons:

•Failure of a DNS lookup

•The hostname isn’t valid.

What you can do is wait till the issue is resolved before attempting again. If you still can’t solve the problem, you can utilise an external DNS provider.


When a recipient installs software that asks you to fulfil a task or respond to an automated message, you’ll get a bounce. Your email will not be distributed if you do not correctly complete the task.

Solution: There is nothing you can do to remedy the problem. Removing those email addresses from your list and trying again later is the best option. Alternatively, if you are able to react individually, go ahead.

There are several different sorts of email bounces. We’ve already covered the most important ones. Now let’s compare hard bounce vs. soft bounce in email marketing.

What’s the Difference Between Hard and Soft Bounce in Email Marketing?

Difference between Hard bounce vs Soft Bounce:

A hard bounce differs from a soft bounce in that the former is permanent while the latter is only transitory.

Hard bounces are caused by invalid email addresses. Soft bounces, on the other hand, are caused by transient issues like as a full mailbox, a server outage, or network congestion.

The basic message is that you should attempt to prevent hard bounces as much as possible because they can lower your sender score and lead to you being banned.

Soft bounces, on the other hand, are nothing to be concerned about because they will resolve on their own. You can wait for the issue to be resolved before trying again.

Email marketing provides a significant return on investment. However, that occurs when your emails arrive in the inbox. You must avoid all of these email deliverability concerns, also known as email bounces, in order to achieve this.

Adhere to the following email marketing best practices:

Use a double opt-in system.

The greatest way to establish a valuable list is to use double opt-in. It ensures that you have a precise count of the number of people who have signed up for your email list. As a result, it prevents you from adding email addresses to your list that are invalid or non-existent.

Keep a tidy list.

Some marketers populate their lists using whatever email address they stumble across. However, doing so may result in inaccurate outcomes in the long run.

Bounces are email addresses that are invalid or do not exist. They can also have a significant impact on your deliverability rates. As a result, keep track of your list on a frequent basis.

Complete the Unsubscription process.

Adding anyone to your mailing list is known as email spamming. It also has the potential to put you on ISP blacklists. Unsubscription requests should always be processed as soon as they are received.

Make use of the best email marketing tools available.

You can eliminate undesired bounces and increase your deliverability by using a professional email marketing tool.

Because automation allows for greater segmentation, you’ll be able to deliver more personalized emails to your subscribers.

Make use of a third-party DNS service.

Email deliverability can also be improved by using an external DNS. It ensures that your IP addresses are not blocked by ISPs due to technical difficulties. If you’ve chosen the best email marketing services, you won’t have to be concerned.

Check and double-check the content of your emails.

Check for any problems in your email content before sending it. Also, double-check all of the email addresses in your list. Avoid Hard and soft bounces in your email marketing efforts by following these easy guidelines.
