Improving the Effectiveness of Email Communication

Why Email Bounce Rate Is Important

Email Bounce Rate is a pivotal metric to measure for clients. It directly reflects the health of email campaigns and the effectiveness of the communication with the audience. When emails bounce, they fail to reach the intended recipients. This could have a variety of causes, including invalid email addresses or a recipient's inbox being full.

Tracking Email Bounce Rate matters for many reasons, such as indicating the quality of the email list. High Bounce Rates signal that it's time to clean up the lists, ensuring the agency is not wasting resources on unresponsive or non-existent contacts. A lower Email Bounce Rate also leads to better email deliverability, helping messages land where they should–in subscribers' inboxes.

Additionally, Email Bounce Rate impacts a sender's reputation. High Bounce Rates negatively affect how email service providers perceive a domain, potentially causing future emails to be marked as spam.

How Email Bounce Rate Relates To Other KPIs

Email Bounce Rate is an important part of the larger picture of marketing KPIs and impacts various aspects of campaign performance. 

One of its direct connections is with Open Rate. When email bounces are high, Open Rates naturally suffer since those bounced emails are never opened. Tracking both metrics together provides a more accurate picture of how well the email messages are resonating with the audience.

Email Bounce Rate also ties closely to Conversion Rate. High Bounce Rates can hinder conversions because if the emails don't reach the intended inbox, they won't lead recipients to take desired actions. Keeping Email Bounce Rate in check helps improve the overall conversion performance of campaigns.

Additionally, it influences Sender Reputation. Email service providers closely monitor Bounce Rates to assess the trustworthiness of a sender's domain. A poor sender reputation leads to emails being filtered as spam, impacting Click-Through Rate and Email Engagement.

How Marketing KPIs Impact Each Other
Understanding Email Bounce Types

Soft Bounce vs. Hard Bounce: What’s the Difference?

When monitoring email marketing campaigns, it's essential to be aware of two primary types of bounces: soft bounce and hard bounce. A soft bounce occurs temporarily, often due to issues with the recipient's email server, such as a full inbox or server downtime. In contrast, a hard bounce indicates a more severe problem, like invalid email addresses or being blocked by spam filters.

The email marketing platform used will typically differentiate between these bounces, aiding in understanding how the Email Bounce Rate is calculated. Maintaining a low average Bounce Rate is crucial, and recognizing the difference between a soft bounce and a hard bounce helps in optimizing for valid recipient email addresses and ensuring successful email delivery.

What Is a Good Email Bounce Rate?

A good average Email Bounce Rate typically falls within the range of 2% to 5%. This indicates that the email campaigns are reaching a high percentage of the intended recipients and that the list is well-maintained.

What Is a Bad Email Bounce Rate?

On the other hand, a bad average Email Bounce Rate is usually above 5%. A high Bounce Rate suggests issues with the email list quality or campaign strategy, impacting the overall email marketing effectiveness.

How To Set Email Bounce Rate Benchmarks and Goals

Analyzing past email performance establishes realistic targets and measures progress more accurately.

To hit growth targets, marketers often back-calculate the desired Email Bounce Rate based on the current benchmarks, strategies being implemented to improve list health, and the desired traffic and conversions from email campaigns.

To dig even deeper, break down Bounce Rates into categories like soft bounces (temporary issues) and hard bounces (permanent issues) or by the email acquisition source. This helps pinpoint specific problems in the email list and campaign strategy, enabling targeted improvements for better results.
