Voicemail systems are crucial for businesses when reaching out to customers, especially when direct communication isn't possible. If a customer doesn't answer their phone, the call often goes straight to their voicemail, making this a vital opportunity to convey important information and shape their perception of your brand. Unfortunately, this critical touchpoint is frequently overlooked, leading to missed connections and potential customer dissatisfaction.

‍

At Retell AI, we understand that every interaction—including voicemails—should reflect a commitment to exceptional service. With the rise of AI voice agents, businesses can now automate voicemail management, personalize messages, and streamline communication workflows effectively.

‍

In this guide, we will explore five best practices tailored for optimizing voicemail systems with AI voice agents. From knowing when to leave a voicemail to crafting effective messages, these actionable tips will help you enhance customer engagement and improve your overall communication strategy.

Why Effective Voicemail Practices Matter

A well-optimized voicemail system ensures customers feel heard and valued, enhancing their overall experience. AI voice agents are transforming how businesses handle voicemail, making the process more efficient and customer-friendly. Here are some insights into how these intelligent systems manage voicemail interactions:

• Automated Voicemail Detection: AI voice agents can automatically detect when a call has reached a voicemail system. This feature allows them to decide whether to leave a message or hang up, based on pre-set criteria, such as the urgency of the call or the recipient's communication habits.
• Personalized Message Delivery: When an AI agent decides to leave a voicemail, it can deliver personalized messages tailored to the recipient. This includes using their name, referencing previous interactions, or addressing specific inquiries, which enhances the overall customer experience.
• Efficient Follow-Up Strategies: AI systems can analyze past call data to determine the best follow-up strategies. For instance, if a customer typically responds better to SMS than voicemails, the AI can send a text message after leaving a voicemail to ensure the message is received.
• Multilingual Capabilities: Many AI voice agents are equipped with multilingual support, allowing them to communicate in the recipient's preferred language. This feature not only improves comprehension but also fosters a sense of inclusivity and respect for diverse customer backgrounds.
• Data-Driven Insights: AI agents can gather and analyze data from voicemail interactions, providing businesses with valuable insights into customer preferences and behavior. This information can inform future communication strategies and help refine messaging for better engagement.
• Streamlined Workflows: By automating voicemail handling, AI agents reduce the workload on human staff, allowing them to focus on more complex tasks. This streamlining leads to faster response times and improved overall efficiency in customer service operations.

Best Voicemail Practices for AI Voice Agents

To provide a seamless and professional customer experience, it's essential to optimize your voicemail system, especially when utilizing AI voice agents. Implementing the following best practices can significantly enhance communication efficiency and customer satisfaction:

1. When to Hit Voicemail and Hang Up

In some scenarios, ending the call after reaching voicemail is the smarter choice. This approach avoids unnecessary messaging and respects the recipient's time, particularly when:

• The Call Is Non-Urgent: If the purpose of the call is routine and can wait for a live conversation, hanging up can be more appropriate.
• Recipient Habits Are Known: If the recipient rarely checks voicemails, leaving one may be ineffective. Instead, follow up using an alternative method like email or SMS.
• Follow-Up Is Planned: For some professionals, a second call attempt within a short time frame is often more productive than leaving a voicemail.

AI voice agents can analyze recipient behavior and communication history to recommend or automate the best course of action, ensuring efficiency without overwhelming the recipient.

2. When to Leave a Voicemail

Voicemails become crucial when there’s a need to communicate important information or ensure follow-up. Key scenarios include:

• Urgent Matters: When a situation requires immediate attention or action, a voice message can quickly convey the urgency.
• Request for Information: If a client has asked for specific details, a voice message allows you to provide a clear and direct response.
• Scheduling and Confirmation: Leaving a voice message to confirm appointments, meetings, or deliverables ensures the message is received and acknowledged.
• Accountability: They create a recorded trail in the recipient's voicemail box, which can be valuable for clarifying commitments or agreements.

To maximize effectiveness, keep voice messages concise and structured: clearly state your name, the purpose of the call, and any required next steps.

3. When to Leave a Voicemail as Well as an SMS

Combining voice messages with SMS can boost response rates and cater to varied communication preferences. Use this approach in cases where:

• Details Are Critical: After leaving a voice message, sending an SMS with summarized key points ensures the recipient has a written reference.
• Urgency Needs Emphasis: Following a voicemail with an SMS underscores the importance of the message.
• Multi-Channel Engagement: Some recipients prefer written communication over voice messages. Offering both options shows flexibility and professionalism.

When implementing this strategy, ensure that both the voice message and SMS maintain a consistent and professional tone. AI voice agents can automate this dual-channel approach for seamless communication.

4. Double-Dial Then Leave Voicemail

Double-dialing—calling back immediately after the first attempt—can signal urgency and improve response rates. This method works well in scenarios where immediate attention is required:

• Critical Updates: For issues that need prompt resolution, the second call underscores the importance of the matter.
• Increasing Visibility: Recipients who see two missed calls followed by a voicemail are more likely to prioritize a response.
• Demonstrating Persistence: This approach shows a commitment to reaching the recipient and resolving the issue at hand.

AI systems can analyze call logs and patterns to determine when double-dialing is most appropriate, ensuring efficiency and minimizing interruptions.

5. Which Language Works Best in Voicemail

The language and tone of a voicemail are essential in ensuring the message resonates with the recipient. Tailoring the message to the audience’s preferences and demographics improves engagement:

• Cultural Relevance: Using a language familiar to the recipient demonstrates respect and inclusivity, fostering a stronger connection.
• Tone and Formality: For B2B clients, a professional and formal tone might be most effective. Conversely, a conversational tone could work better for retail or casual interactions.
• Multilingual Capabilities: AI voice agents equipped with multilingual functionality can deliver personalized messages in the recipient’s preferred language, improving comprehension and building rapport.

The flexibility to adjust language and tone ensures every voice message feels personal and aligns with your brand’s values.

• Leave a Message: Choose this to have the agent play a pre-recorded or dynamically generated message.

3. Configure Detection Duration

Set the duration for how long voicemail detection remains active during a call:

• Recommended Timeout: Start with 30 seconds and adjust based on your needs. For instance, extend the duration if voicemail detection occurs later in the call.

This ensures voicemail detection is accurate while avoiding false positives during longer calls.

4. Set a Voicemail Message (Optional)

If you’ve chosen the “Leave a Message” option:

Input the message you want your agent to deliver. Options include:

Examples of Effective AI Voicemail Prompts

AI voice message systems can enhance customer interactions by providing clear, professional, and engaging prompts. Here are some effective examples that businesses can use or adapt for their voicemail greetings:

Example 1: Professional and Reassuring Prompt

“Hello! You’ve reached [Company Name]. We’re unable to take your call right now, but your inquiry is important to us. Please leave your name, contact number, and the purpose of your call. Our team will get back to you within 24 hours.”

This prompt reassures callers that their message is valued and sets clear expectations regarding response time. It encourages callers to provide essential information for efficient follow-up.

Example 2: Friendly AI Assistant Prompt

“Hi! This is [AI Assistant Name] at [Company Name]. I’m here to assist you.

Please let me know how I can help by leaving a detailed message. We’ll be in touch soon!”

This greeting creates a friendly atmosphere while inviting the caller to share their needs. It emphasizes the assistant's readiness to help, which can enhance customer satisfaction.

Example 3: Direct and Efficient Prompt

“Thank you for calling [Company Name]. We are currently assisting other customers. Please leave your name, number, and a brief message, and we will return your call as soon as possible.”

This straightforward message respects the caller's time by acknowledging their call while providing clear instructions on what to do next.

Example 4: Urgent Need Prompt

“Hello! You’ve reached [Your Name] at [Company Name]. I’m currently unavailable. If this is urgent, please send me a text at [Your Number], or leave a message with your details, and I’ll get back to you as soon as I can.”

This prompt addresses urgent situations by offering an alternative method of communication while still inviting voice messages.
