1. Open Rate

The open rate, expressed as a percentage, reveals the proportion of recipients who opened your email. It's a critical metric as it indicates the effectiveness of your subject lines and the appeal of your content.

Additionally, it also suggests what is the best time and day to send the mail based on the open rate.

The average open rate for B2B emails is around 15%. However, benchmarks can vary by industry, so it's essential to gauge your performance against your specific sector.

2. Click-Through Rate (CTR)

4. Bounce Rate

Bounce rate represents the percentage of emails that were not delivered to the recipient's inbox. There are two types of bounces: Hard bounce and soft bounce.

A hard bounce is when the email address has been closed down permanently. This usually happens when the recipient has switched jobs. In this case, you should stop sending more emails to this address. A soft bounce is when the email address is temporarily invalid. This happens for two reasons: the recipient is facing server issues, or their email box is full. In this case, you should re-send the email at a later time.

You should continuously maintain your bounce rate to the lowest possible percentage to ensure a clean and active email list.

According to Campaign Monitor, the acceptable bounce rate for B2B email campaigns is typically below 2%. Beyond this threshold, it's crucial to investigate and address the underlying issues, such as outdated email addresses or list hygiene.

5. Unsubscribe Rate
