What is our process for handling bounced or undeliverable messages/calls?
Posted: Sun May 25, 2025 7:07 am
Bounced and undeliverable messages or calls are an inevitable part of modern communication, particularly in the realm of mass outreach, customer service, and digital marketing. Whether it's an email rejected by a server, a text message failing to reach a device, or a phone call that goes unanswered or encounters a disconnected line, these communication failures represent more than just minor technical glitches. They can impact efficiency, waste resources, damage sender reputation, and ultimately hinder the achievement of communication objectives. Therefore, establishing a robust and systematic process for handling these occurrences is not merely a best practice; it's a strategic imperative for any organization relying heavily on external communication.
Our process for managing bounced or undeliverable messages and calls is multifaceted, encompassing identification, analysis, remediation, and proactive prevention. It is designed to minimize the negative impact of these failures while continuously improving the effectiveness and deliverability of our communication channels.
The initial step in our process is identification and categorization. For email, this primarily involves the interpretation of bounce codes. A 'soft bounce' typically indicates a temporary issue, such as a full dominican republic phone number list or a server being temporarily down. These messages are usually retried a set number of times over a defined period. If they continue to bounce, they are then treated as a 'hard bounce,' which signifies a permanent delivery failure due to an invalid email address, a deactivated account, or a blocked sender. For SMS, delivery reports from our messaging gateway provide similar insights, indicating whether a message was delivered, pending, or failed. Failed messages often come with specific error codes that help us understand the reason for non-delivery, such as an invalid number, a network error, or a subscriber opt-out. For phone calls, our call management system logs all calls, noting outcomes such as "no answer," "busy," "disconnected," or "invalid number." These outcomes are automatically categorized based on predefined rules.
Once identified, the next crucial phase is analysis and investigation. This involves delving deeper into the reasons behind the communication failure. For email, we examine the bounce message in detail. A common hard bounce reason is an invalid email address. We cross-reference these addresses with our customer database to check for any discrepancies or potential data entry errors. If a large number of bounces originate from a specific domain, it might indicate our IP address has been blacklisted or our content is being flagged as spam by that particular email provider. For SMS, we analyze the error codes provided by the carrier. An "unknown subscriber" error points to an invalid number, while a "network error" suggests a temporary disruption. If a high volume of SMS bounces occur in a particular region, it could signal issues with a specific mobile network. For calls, "disconnected" or "invalid number" outcomes are flagged for immediate investigation. We might attempt to verify the number through a secondary source if available or note it for potential removal from our active calling lists.
The third stage is remediation and action. This is where we actively address the identified communication failures. For hard bounce emails and SMS messages with permanent failure codes, the corresponding contact information is immediately flagged and, in most cases, removed from our active communication lists. This is critical for maintaining a healthy sender reputation. Continuously sending to invalid addresses can lead to our IP address being blacklisted, impacting the deliverability of all our communications. For soft bounces, our system automatically retries delivery for a set period. If persistent soft bounces occur, we may reclassify them as hard bounces after a predefined number of retries. For phone numbers flagged as "disconnected" or "invalid," these are also promptly removed from our active calling lists. In some cases, for particularly valuable contacts, we might initiate an internal process to find updated contact information through alternative channels, such as a different department or a direct query to the contact's organization if appropriate.
Beyond individual remediation, our process emphasizes proactive prevention and continuous improvement. We regularly review bounce and undeliverability rates across all our communication channels. This involves generating reports that highlight trends, such as increasing bounce rates for a specific campaign or a particular demographic. If we notice a significant uptick in email bounces, we might review our email content for potential spam triggers or adjust our sending volume. If SMS delivery rates decline in a specific region, we investigate potential carrier-specific issues or explore alternative routing options. For phone calls, we analyze patterns of unanswered calls to identify optimal calling times or consider implementing voicemail drop strategies for certain call types.
Furthermore, we implement several preventative measures upstream. Data validation at the point of entry is paramount. For example, our online forms include real-time email and phone number validation to minimize invalid entries. We also periodically cleanse our contact databases using third-party validation services to identify and remove outdated or incorrect information. This proactive data hygiene significantly reduces the likelihood of sending messages or making calls to undeliverable addresses or numbers in the first place. For email, we adhere strictly to best practices for sender authentication (SPF, DKIM, DMARC) and maintain a low complaint rate to foster a strong sender reputation. For SMS, we ensure compliance with all relevant regulations, including opt-in requirements, to minimize instances of subscriber opt-outs and blocked messages.
Finally, feedback loops and reporting are integral to our continuous improvement cycle. We generate regular reports on bounce rates, delivery success rates, and the reasons for undeliverability across all our communication channels. These reports are shared with relevant teams – marketing, sales, customer service, and IT – to foster a shared understanding of communication effectiveness and to drive further improvements. We also actively monitor blacklists and adjust our strategies accordingly. Our process is not static; it evolves based on new technologies, changing communication landscape dynamics, and the insights gleaned from our continuous monitoring and analysis.
In conclusion, handling bounced or undeliverable messages and calls is a critical operational function that directly impacts communication effectiveness, resource utilization, and brand reputation. Our comprehensive process, encompassing identification, analysis, remediation, proactive prevention, and continuous improvement, ensures that we efficiently manage these communication failures. By systematically addressing undeliverability, we not only reduce wasted effort and resources but also enhance the overall deliverability and impact of our communications, ultimately strengthening our connections with our audiences and achieving our strategic objectives.
