Usually as a sender you may choose to concentrate on the positive metrics of your mailouts, and work on improving these rates and indicators. However, it is of high importance to take into account negative metrics such as hard at nd soft bounces as they influence email deliverability, sender reputation, cost-effectiveness, and other no less important metrics. This article contains general information on hard and soft email bounces, and also ways and practices that can be used to eliminate the common reasons for soft bounces.
Email bounces refer to emails that could not be successfully delivered to the recipient’s mailbox. For instance, When an email service provider fails to deliver an email to the intended recipient due to issues like Simple Mail Protocol (SMTP) errors, the sender typically receives an automatic reply detailing the reason for the non-delivery. Email bounces are a critical metric for businesses and organizations that rely on email marketing or regular communications with clients, customers, or stakeholders.
Email bounces are generally categorized into two types: hard and soft bounces. A hard bounce occurs when the email cannot be delivered due to a permanent issue, such as an invalid email address. When it comes to what is a soft bounce email, it is the case when the bounce is caused by temporary issues, like a full inbox or server downtime, which are likely to be resolved, making future delivery possible.
Deeply understanding the distinctions between these types of bounces is vital for improving email deliverability and engagement rates. For a comprehensive understanding, the soft bounce vs hard bounce email table below enumerates the major reasons contributing to each type of email bounce:
| Hard Bounce | Soft Bounce |
|---|---|
| Provided recipient’s email address is invalid (for example, because of typos or wrong syntax) Provided recipient’s email address does not exist | The sender had too many hard bounces Many spam complaints were submitted against this sender The sender’s server is blocked Low client engagement with the sender’s mailouts The recipient’s mailbox is full The recipient’s mail server is offline The sender’s reputation is too low compared for mailbox provider’s standards The sender sent too many emails within a certain period Connectivity problems with the recipient’s Internet Service Provider |
As you can see, the difference between hard and soft bounce email is clear and requires a nuanced approach to understanding in order to address the resulting issues effectively.
Addressing hard bounces requires a distinct strategy compared to managing soft bounces, as the former often results from permanent issues that cannot be remedied by merely resending the email. Meanwhile, the situation with soft bounces is somewhat more complex. To reduce the frequency of soft bounces, improve email deliverability, and safeguard the sender’s reputation, it is crucial to identify and address the root causes. In this section, we will outline the most common email soft bounce reasons and provide strategies for resolving them.
As previously mentioned, one reason for soft bounces could be accumulating too many hard bounces during mailouts. Once hard bounces occur, they can’t be reversed. However, they can be avoided or minimized initially. A high bounce rate signals to the email service provider that the mailing list may be poorly maintained or the mailouts could be considered spam.
To prevent hard bounces:
It’s advisable to employ email address validation mechanisms in sign-up forms, which can be achieved through email autodial system , to avoid adding invalid email addresses to your list.
Emails are often marked as spam by recipients who don’t remember subscribing or when the “Unsubscribe” option is hard to find. Since spam complaints tarnish your reputation with internet providers, it’s crucial to minimize them, using the following strategies:
Make sure to keep an eye on spam complaints as it is one of the most common troubleshooting email bounce backs.
The reputation of the IP and domain from which emails are sent is crucial to maintaining the sender’s overall reputation. If the IP or domain gets blacklisted by an internet service provider, all outgoing emails from those sources will be blocked. After being placed on a blocklist, it is essential to identify the root causes that led to the blocking and subsequently send a request to the provider to remove you from the list, or wait for it to be done automatically. Sometimes your communication services provider can take such responsibilities. For instance, BSG service proactively monitors all blocklists to ensure that none of our registered IP addresses or domains are listed.
If recipients display low engagement with the email content, some internet providers may interpret this as a sign of poor-quality content, which can lead to a soft bounce. To mitigate this the followingcan be recommended:
Also, remember that improving recipient engagement is a proven method for reducing the incidence of soft bounces and should be incorporated into your email marketing strategy.
One of the reasons for email soft bounce is the recipient’s full mailbox that may indicate that the individual uses that email address primarily for unwanted marketing emails. To avoid this type of soft bounce:
Keeping your mailing list clean is an effective way of troubleshooting email bounce back.
Soft bounces can sometimes result from a sudden increase in the volume of emails sent, which some internet service providers might deem suspicious. To prevent this type of soft bounce, it’s advisable to maintain a consistent email sending volume. If you anticipate a need to send a larger volume of emails due to a special event or campaign, consider gradually ramping up the email count starting at least 30 days before the event.
By adhering to a consistent sending volume and planning for high-traffic events, you can minimize the risk of triggering soft bounces due to exceeded volume limits.
Understanding email bounces, both hard and soft, is essential for effective email marketing. While hard bounces are irreversible and stem from permanent issues like invalid email addresses, soft bounces arise from temporary challenges such as server downtime or full mailboxes. Yet, with a deep revelation of nuances of these bounces it is possible to implement targeted strategies to troubleshoot soft bounces specifically. Make sure to maintaining a clean mailing list, reduce spam complaints, and ensuring a good sender reputation. By taking a proactive approach to address the root causes of soft bounces, marketers can improve deliverability and engagement, ultimately boosting the efficacy of their email campaigns.
