Best Practices
-
Enable Lead Engage through Lead Routing Rules so new leads receive an immediate response when they enter your CRM. Speed to first contact plays a critical role in engagement and conversion.
-
Prioritize opting in new leads first. Clients typically see significantly higher response rates when Lead Engage is applied to fresh, newly generated leads versus older or colder contacts.
-
Use Lead Engage as a first-touch and qualification layer, not a replacement for human follow-up. Once a lead responds, transition the conversation to a team member as quickly as possible.
-
Monitor conversations regularly, especially during the first few weeks of usage, to ensure responses align with your business goals and communication style.
-
Combine Lead Engage with strong lead management workflows, such as tasks, alerts, and follow-up plans, to maintain momentum after the initial engagement.
- Audit lead records for landline numbers before enabling Lead Engage, especially for large or older databases
- Set up an automation to pause Lead Engage once a lead replies, to prevent redundant outreach and reduce segment consumption at handoff
Troubleshooting Common Issues
| Issue | Likely Cause | Fix |
|---|---|---|
| Lead not receiving messages | Landline number on file | Update lead with mobile number |
| Lead reassigned to another agent | Lead Engage paused | Re-enroll under new agent |
| Opt-in not working | Agent lacks permission | Confirm manager settings |
FAQs
-
Does Lead Engage replace my agents?
No, Sierra AI’s role is to engage and qualify leads. Once a lead responds, your agents take over. -
How much does Lead Engage cost?
$199/month with 12-month commitment (Dialer overages excluded). -
Can I customize the AI’s responses?
No, Sierra AI uses tailored scripts based on your account settings and lead context. -
Can IDX-only customers use it?
No, Lead Engage is not available for IDX-only accounts. -
How long does it nurture leads?
Up to 12 months from initial opt-in. -
What if I don’t want AI to contact certain leads?
You can exclude them in routing rules or simply avoid toggling Sierra AI for that lead source -
Can Lead Engage have conversations in Spanish?
Lead Engage can engage in Spanish conversations and will respond if a lead texts in Spanish or asks for Spanish support. However, this capability isn’t as comprehensive as it is in English and may occasionally produce imperfect responses. - Why am I being charged for messages that weren't delivered?
Twilio bills at the point of send, not delivery. Undelivered messages still count against your monthly allotment. A common cause is leads with landline numbers on file, since texts to landlines will fail but still incur a charge. Before enabling Lead Engage, we recommend auditing your lead records to ensure contacts have valid mobile numbers. This is especially important for large or older databases where landline entries are more likely. - What is a segment, and how does it affect my bill?
Lead Engage bills by segment, not by message. A single text message can use 2–7 segments depending on its length and character encoding. The first message Lead Engage sends is 6 segments by design, it includes required compliance language that cannot be removed. Across a full conversation, Lead Engage averages around 3 segments per message. If you're estimating monthly usage, plan around segment volume rather than message count. - I'm already texting leads manually. Will that affect my Lead Engage usage or bill?
Yes, Lead Engage can run at the same time as Action Plans and manual texting from agents. That means the same lead may be receiving texts from three separate sources simultaneously. Clients who are already active texters outside of Lead Engage carry the highest overage risk. Before going live, confirm whether other text sources are running against the same lead pool.
