Bounce

A bounce is an email that doesn’t reach its recipient and returns to the sender with an error notice. In email marketing, it’s measured with the bounce rate: the percentage of emails sent that couldn’t be delivered.

It can be a hard bounce, when delivery is permanently impossible, or a soft bounce, when the failure is temporary. If bounces pile up, they damage your sender reputation and deliverability.

The term is also used in web analytics. There, a bounce is a visit that leaves a page without interacting with it.

Types of bounces

There are several types of bounce in digital marketing, depending on the context in which it is applied.

The two most common ones are:

Bounce in email marketing

In this context, a bounce occurs when an email sent fails to reach its recipient and is returned.

There are two main types of bounces in email marketing: hard bounce and soft bounce, which we’ll explore below.

Bounce on websites

This occurs when a visitor leaves a website after viewing only one page.

It is an indicator used in web analytics tools such as Google Analytics.

Bounce metrics

The main metric is the bounce rate. In email marketing, it shows what percentage of emails sent couldn’t be delivered, and you should mainly keep an eye on hard bounces. We explain it in detail in bounce rate.

In web analytics, the bounce rate measures the visits that leave without interacting. A high rate isn’t always bad: it’s normal for an informational article, but on a landing page designed to convert it can point to a problem.

Bounces in email marketing: how to avoid them?

To measure it, use the bounce rate, which shows what percentage of emails sent couldn’t be delivered.

As mentioned above, there are two main types of bounces:

Hard bounce:

It happens when an email can’t be delivered permanently.

This can happen for various reasons, such as an incorrect email address, a non-existent domain, or the recipient’s server blocking the message permanently.

With a hard bounce, there is no chance that the email will be delivered in the future.

Soft bounce:

Unlike hard bounces, this type of bounce is generated when an email is temporarily undeliverable.

Reasons may include the recipient’s inbox being full, the recipient’s mail server being down, or the message being too large to be received.

In these cases, the message may be delivered in future attempts.

How to minimize email marketing bounces

Minimizing bounces in email marketing is crucial to maintaining your domain reputation and improving the effectiveness of your campaigns.

Some strategies for reducing the number of bounces include:

Maintain an updated mailing list

It is important to regularly clean up your contact list by removing inactive or incorrect email addresses.

Email verification tools can help identify invalid addresses before you send campaigns.

Avoid using terms that trigger spam filters

Some terms or phrases, such as “free,” “100% guaranteed,” or “exclusive offer,” can trigger spam filters and cause emails to miss the recipient’s inbox.

Limit the size of attachments

Very large attachments can cause a soft bounce.

It is advisable to reduce the size of documents or images, or provide a download link instead of directly attaching files.

The impact of bounce on digital marketing performance

Understanding and managing bounce is critical to any digital marketing strategy, as it can have a significant impact on several aspects of a campaign.

In the case of web analytics, a high bounce rate could be a red flag for problems with content, design or site functionality.

In email marketing, bounces can damage your domain’s reputation, causing email service providers (ESPs) to mark your messages as spam.

Consequences of a high bounce rate on websites

• Loss of conversion opportunities: if users leave a web page quickly, the likelihood of them taking a valuable action, such as making a purchase or filling out a form, decreases dramatically.
• Damage to SEO: although Google doesn’t reveal all the factors that influence its ranking algorithm, it is believed that a high bounce rate could negatively influence search ranking, as it can be interpreted as a signal that the content is not relevant or doesn’t meet the user’s needs.

Consequences of a high bounce rate in email marketing

• Poor deliverability: a high bounce rate in email marketing can negatively affect the deliverability of your emails. This happens because email providers tend to mark senders with high bounce rates as spam.
• Damage to the sender’s reputation: if email campaigns generate a lot of bounces, the reputation of your IP address or domain can be affected, which in turn will make it harder to deliver future emails.

Conclusion

Bounce is a key concept in both web analytics and email marketing, and its impact should not be underestimated.

On websites, a high bounce rate can signal problems in the user experience, while in email marketing, bounces can damage your ability to reach recipients.

Therefore, it is essential to monitor these metrics and apply strategies to reduce them, thus improving the effectiveness of your campaigns and user satisfaction.
