What is email bounce?

Email bounces are the annoying phenomena that occur when email messages are unable to be sent to a recipient’s email address. They may be a cause of great distress — blood, sweat, tears, curses… an email bounce can surely knock you off track.

There are several reasons for an email to bounce. As a result, a “return to sender” message (also known as an SMTP Reply) is sent from the recipient’s mail server, along with a more thorough explanation for the bounce back. It’s a vexing phenomenon in email delivery. Regardless of how prevalent they are, bounced emails drive senders insane.

What is the email bounce rate?

The email bounce rate is the proportion of email addresses in a mailing list that did not get promotional messages because their mail servers returned them. Bounces occur when emails are unable to be delivered to email addresses.

Limits for unsubscribes, abuse, and bounces are determined by Internet Service Providers (ISPs). When these rates exceed a certain threshold, ISPs can take action against advertisers by issuing warnings or terminating their accounts entirely.

Marketers may prevent negative effects by building and sending distinctive marketing campaigns with low bounce rates, which can be accomplished by meticulously monitoring server reputation.

What is a good Email Bounce rate?

It is quite unusual to have an email campaign with a 100% deliverability rate. Even if you’ve taken every precaution to verify the reliability of your contact list, there are still things beyond your control.

The industry standard for bounced emails is 2%. This implies that for every 100 emails you send, you will receive two in return. Often, your bounce rate will be far lower.

Anything between 2% and 5% should be taken into account. It might be a one-time issue that fixes itself with your next email send. If you detect a bounce rate of more than 5%, you must act quickly to resolve the problem.

It’s also worth noting that bounce rates may vary somewhat depending on the industry. Similar to how varied email open rates were per industry in 2018, you’ll observe varying bounce rates.

Types of Email Bounces?

Transient: The destination mail server is unable to deliver your email but will continue to attempt delivery for a short time. We consider this a mild bounce since the message may be delivered if the receiving mail server retries.

Spam: Because the content of your email resembles spam, the recipient’s email server has banned it. This mail block is frequently triggered by anything identified in your email content, but it might also be your reply-to address or a brand name with a bad reputation.

Because certain mail servers and email providers react with misleading or inaccurate error codes, we interpret this as a soft bounce.

Block: A block bounce happens when an email is rejected by the email server due to a lack of authentication or if the domain or IP address is on a block list. When a subscriber receives a block bounce, the email is resent.

Hard: Your email has been marked as permanently undeliverable to this email address. The address is either bogus, wrongly typed, or the user mailbox or domain is no longer active.

We’ve deleted the address from your mailing list and added it to your suppression list, which means no more emails will be sent to it. This preserves your sender’s reputation and prevents you from paying to transmit to invalid addresses.

Soft: A soft bounce indicates that the email address was legitimate and that the message was delivered to the recipient’s mail server. However, some of the most prevalent reasons for its resurgence are as follows:

The mailbox was overflowing (the user is over their quota)
The server was unavailable.
Because the communication was too big for the recipient’s inbox

we will continue to try to send it for up to 72 hours until it is delivered. We convert these addresses to a block/deferral list if a message is consistently postponed for 72 hours. (This is not a suppression list; it is a deferral list.)

General: We are treating this as a soft bounce since we are unable to pinpoint the specific cause of the delivery failure. This bounce category is typically connected with a technical issue such as “Connection timed out,” but we will also label a bounce as “generic” if the answer from the receiving server is susceptible to more than one interpretation. It might be a non-standard error message, or it could be too ambiguous to be informative.

how to Reduce Bounce Rate?

If your soft bounces have risen over 2% to 5% or more, you can take a few actions to reduce them to a more manageable level.

  • Use a two-step opt-in process. Send a confirmation email to new subscribers with a link to click to validate their address. This ensures that you only send emails to those who want to hear from you.
  • Be wary of incentivized sign-ups. While free Wi-Fi and lead magnets are wonderful for gathering contact information, they can also lead to people entering false email addresses. Check your list and tidy up as needed.
  • Use a trusted email service provider. Using an email service provider like Campaign Monitor guarantees that your campaigns are sent from a high-quality IP address with a solid sending reputation.
  • Authenticate your domain. A decent email service provider should assist you in authenticating or verifying your domain. This will inform email clients that you are who you say you are and that you are not spamming their subscribers..

How to Calculate Email Bounce Rate?

The bounce rate may be simply computed by dividing the total number of bounced emails by the total number of emails sent. The proportion is then multiplied by 100.

“Bounce Rate = (Bounced Emails/Sent Emails) x 100

Conclusion

For an email marketing campaign you need a good amount of email list and also you need to do verification and validation of your list. if you do not do this that can make your email bounce and ban you from the campaign and this is a bad reputation for your company and domain.
