Followup Smartlead.ai Campaigns
With Topa.io, you can connect your Smartlead.ai email campaigns directly to Topa and automatically send AI-generated voicemails, SMS messages, and WhatsApp messages to your prospects. This helps you 5X–10X your reply rates by combining email + voicemail + SMS + WhatsApp follow-ups. Follow the steps below to set up your Smartlead.ai campaign.
How the Integration Works
Once connected:
Smartlead.ai sends an email / an email is opened / an email is clicked.
Smartlead.ai triggers a webhook event.
Topa receives the webhook.
Topa automatically:
Finds the contact's cellphone number
Drops a voicemail (optional)
Sends an SMS (optional)
Sends a WhatsApp message (optional)
You can also configure multiple follow-up steps, allowing voicemail, SMS, and WhatsApp messages to trigger throughout your Smartlead.ai email sequence.
Step 1 — Create a New Smartlead.ai Campaign
From your Topa.io dashboard:
Click Create New Campaign
Select Smartlead.ai Campaign
Optional Settings
Daily Voicemail Limit
Apply a limit to control how many voicemails are sent every 24 hours. This helps manage sending volume and costs.
Step 2 — Enter Campaign Details
Fill in the required campaign information:
Campaign Name
Send Number
AI Voice
You can click Test to preview the AI voice.
Writing Your Voicemail Script
Your voicemail message is created in two parts.
Enter the template text for:
Part 1
Part 2
Example Structure
Part 1: Greeting and context
Part 2: Call-to-action or follow-up instructions
Use punctuation to improve clarity and pacing in the AI-generated audio.
Step 3 — Generate and Preview the Voicemail
Before continuing, you must generate the second part of the voicemail message.
Click Generate
Listen to the preview audio
Confirm the message sounds natural and that names or phrases are pronounced correctly
If needed, you can:
Adjust wording
Add punctuation (such as !, …, or -)
Click Generate again to regenerate the audio
Repeat until the voicemail sounds correct.
Step 4 — (Optional) Enable SMS and WhatsApp Follow-Up
If your sending number supports SMS, you can send a follow-up message alongside the voicemail.
SMS
Toggle Send SMS
Enter your SMS message
If your WhatsApp account is connected to Topa.io:
Enable WhatsApp
Enter your WhatsApp message
Supported Variables
{name}
{company}
Example Message
Hi {name}, I just left you a quick voicemail about the email I sent. Feel free to reply here if it's easier.
Note: WhatsApp messaging is available once your WhatsApp account is connected to Topa.io.
Step 5 — Add Additional Campaign Steps
You can trigger voicemail, SMS, and WhatsApp actions on multiple steps within your Smartlead.ai email sequence.
By default:
Step 1 triggers a voicemail, SMS, and/or WhatsApp message when the email is sent.
You can also:
Add additional steps
Trigger voicemail, SMS, and WhatsApp messages later in the email sequence
Topa allows up to 10 campaign steps.
This allows you to create multi-touch outreach across:
Email
Voicemail
SMS
WhatsApp
Step 6 — (Optional) Add a Campaign Webhook
If you want to receive voicemail and SMS delivery results through a webhook, you can enable this feature.
Example Webhook Response
{
"destinationnumber": "+447534000000",
"name": "Jonny",
"company": "",
"email": "",
"linkedinurl": "",
"custom1": "",
"custom2": "",
"custom3": "",
"date_time": "2025-12-08T16:12:27.833665+00:00",
"campaign": "Test",
"voicemail_text": "Hi Jonny...",
"detail": "Voicemail drop successful (machine_end_beep)",
"voicemail_status": "SUCCESS",
"sms_status": "sent",
"source": "webhook"
}Step 7 — Create the Campaign and Copy the Webhook URL
Click Create Campaign
Copy the Webhook URL shown on the confirmation screen
You will use this URL when connecting Smartlead.ai in the next step.
Step 8 — Connect Topa.io to Smartlead.ai
Inside Smartlead.ai:
Go to Settings → Webhooks
Click Add a Webhook
Paste the Webhook URL from Topa.io
Set Event Type to Email Sent (or another event if desired)
Select the Smartlead.ai campaign you want to connect
Click Save
Once connected, Topa will automatically trigger voicemails, SMS messages, and WhatsApp messages based on email activity in Smartlead.ai
Step 9 — Manage Leads and Conversations in Topa
When leads are processed through the campaign, Topa can automatically:
Find B2B cellphone numbers
Deliver voicemails
Send SMS messages
Send WhatsApp messages
You can manage these leads inside Topa's Inbox, where you can:
Reply to SMS messages
Reply to WhatsApp messages
Send additional voicemails
Continue conversations with prospects
Topa also functions as a mini CRM, allowing you to:
Add notes
Assign lead owners
Update lead statuses
Manage a blacklist
You can also enrich additional B2B contacts and push them into the inbox to start SMS or WhatsApp conversations.
Step 10 — (Optional) Provide White-Label Access to Clients or Staff
You can provide a white-label login to team members or clients.
From their login, users can view:
Delivered voicemail records
SMS delivery results
WhatsApp conversations
Inbox conversations with leads
Enriched cellphone numbers
They can also:
Reply to leads via SMS
Reply to leads via WhatsApp
Send voicemails
Manage blacklist entries

The white-label dashboard contains no Topa branding, allowing agencies to share campaign results with clients while maintaining their own brand experience.
