“Hey, just checking if you saw our offer?”
It’s the kind of message that either gets ignored or, worse, blocked.

Mass-blasting customers without context is like shouting into the void. But imagine this instead: a WhatsApp message lands with your name on it, referencing your last order, paired with a voice call that actually understands your query. Now we’re talking engagement, not interruption.

With Outreach by Verloop.io, connect with your audience. Whether it’s a festive sale reminder, a payment nudge, or a personalised welcome message, Outreach helps businesses break through the noise with WhatsApp campaigns that are not just timely but tailored.

And the magic doesn’t stop at chat. With Voice AI, you can add human-like conversations to your outbound strategy, making every call feel like it was made just for them.

The results?

• Businesses using WhatsApp campaigns report up to 98% open rates and 45–60% response rates, a world apart from traditional email or SMS outreach.
• Voice AI can reduce operational costs by up to 40%, while increasing first-call resolution and call containment, especially during peak periods.

In this blog, we’ll explore how Verloop.io’s Outreach solution helps you reach more customers, boost conversions, and build lasting relationships and all without sounding like a bot.

What is Outreach?

Outreach by Verloop.io is a proactive customer engagement tool that allows businesses to send personalised messages and voice calls at scale using WhatsApp and Voice AI.

Think of it as your automated outreach engine—designed to help you connect with the right customer, at the right time, through the right channel. Whether it’s a festive promotion, order update, payment reminder, or re-engagement campaign, Outreach enables your brand to deliver context-rich, two-way conversations that drive action.

Here’s what you can do with Verloop.io’s Outreach:

• Run WhatsApp campaigns with personalised templates, segmentation, and real-time analytics.
• Trigger Voice AI calls that sound natural and can handle dynamic user responses.
• Automate follow-ups based on customer behaviour or journey stage.
• Track campaign performance and iterate with insights.

Unlike traditional marketing blasts, Verloop.io’s Outreach is designed to feel human, relevant, and helpful, boosting open rates, conversions, and long-term loyalty.

Why is proactive engagement important?

Waiting for customers to reach out is a missed opportunity.

Instead of sitting back and hoping a customer asks for help, proactive engagement allows businesses to initiate conversations at the right moment, on the right channel. Whether it’s sending a WhatsApp reminder about a delivery, a personalised discount code, or a voice call to confirm an appointment, being one step ahead shows customers you’re paying attention.

And the data backs it up:

• Brands that engage proactively see a 25–30% increase in customer satisfaction (Source: Forrester).

• Proactive support reduces inbound queries by 20%, freeing up agent bandwidth for more complex issues.

• Businesses using proactive messaging on channels like WhatsApp have reported 2x higher conversion rates.

With Outreach by Verloop.io, you can use WhatsApp and Voice AI to deliver timely nudges, reduce churn, and build stronger relationships, without waiting for the customer to make the first move.

Why Use WhatsApp for Outreach Campaigns?

When it comes to outbound engagement, WhatsApp isn’t just another messaging app, it’s where your customers already are. With over 2 billion users worldwide and a staggering 98% open rate, WhatsApp offers unmatched visibility and responsiveness compared to traditional channels like SMS or email.

But the real power lies in what you can do when you pair WhatsApp with proactive outreach.

Here’s why running your outreach campaigns on WhatsApp, especially through Verloop.io, makes business sense:

It’s real-time and personal

WhatsApp messages are seen faster and responded to sooner. And when you combine that immediacy with personalised messaging, customers don’t feel spammed—they feel seen. From using first names to referencing past purchases or issues, WhatsApp enables brands to talk to customers, not at them.

It drives higher engagement

Compared to emails that often land in spam or go unread, WhatsApp messages get opened, clicked, and replied to. Campaigns run on WhatsApp through Verloop.io often see engagement rates 2–3x higher than traditional channels.

Two-way communication at scale

WhatsApp isn’t just for sending messages—it’s built for conversations. With Verloop.io, you can go beyond broadcasting updates. Enable customers to reply, ask questions, or take action—all within the same chat. Whether it’s Quick Reply buttons, CTAs, or voice-assisted follow-ups, your outreach becomes interactive and dynamic.

It’s secure and compliant

Customers are more likely to trust communication on WhatsApp because of its end-to-end encryption. Verloop.io ensures that all your campaigns comply with WhatsApp Business API policies, including opt-ins, so you’re always on the right side of data privacy regulations like GDPR or PDPA.

It scales with automation

You don’t need a large team to send 10,000 messages. With automated campaign flows, integrations with MoEngage/CleverTap, and Voice AI follow-ups, Verloop.io helps you scale your outreach without compromising on personalisation or quality.

You get insights, not just delivery receipts

Outreach campaigns on WhatsApp via Verloop.io don’t end with message delivery. You get detailed reports on open rates, replies, clicks, and even customer responses saved as variables, so you can iterate and improve with every campaign.

If you want outreach that actually gets seen—and more importantly, drives action—WhatsApp is no longer optional. It’s essential.

What’s new with WhatsApp Outreach?

Managing outbound campaigns shouldn’t feel like a juggling act. With Verloop.io’s updated Outreach dashboard, support and marketing teams get a streamlined way to plan, personalise, and optimise WhatsApp campaigns at scale—without switching between tools or relying on guesswork.

Here’s a breakdown of the latest features that make proactive engagement smarter, faster, and more actionable.

Preview campaigns at a glance

Earlier, campaign names alone made it difficult to identify what message was sent and to whom. Now, with a message preview directly on the dashboard, you can quickly spot which campaign is what, reducing confusion and saving you from opening each one manually.

Smarter search to find what matters

Looking for a specific campaign or template from last quarter?

You no longer have to remember exact titles. The improved search functionality now lets you find campaigns using keywords from the message content, making it easier to navigate large volumes of outreach.

Fully customisable dashboard

Not every team tracks the same metrics. The latest update allows you to customise your view by adding or removing columns such as delivery status, engagement rate, template name, and more. You can rearrange columns based on your workflow or hide the ones you don’t need, so your dashboard shows only what’s relevant to you.

Test messages before going live

Spotted a typo too late?

We’ve all been there. With the new testing feature, you can now send a test version of your WhatsApp message before the campaign goes live. This ensures formatting, links, and variables work exactly as intended—no surprises for your end users.

Real-time performance tracking

Campaign success shouldn’t be a mystery. The Outreach dashboard now shows performance insights such as open rates, clicks, and delivery metrics. These actionable stats help you analyse what’s working, optimise messaging, and improve results over time.

Make messages interactive

One-way messages are easy to ignore. With support for WhatsApp Interactive Messages, you can now include Quick Reply buttons and Call-to-Action buttons in your campaigns, making it easier for users to respond, book, buy, or chat with just a tap.

Store responses as variables

What if your campaign could learn from how customers respond?

Now, you can capture user responses from outreach campaigns and store them as variables. This data flows directly into your reports, allowing for richer segmentation, smarter follow-ups, and improved personalisation in future interactions.

Built-in payments dashboard

Running out of messaging credits mid-campaign is a marketer’s worst nightmare. Verloop.io solves this with an integrated Payments Dashboard where you can recharge your wallet instantly, ensuring that your outreach efforts continue uninterrupted.

Why Use Voice AI for Outreach Phone Calls?

While WhatsApp messages are great for silent scrolls, sometimes your message needs a voice. Whether it’s a time-sensitive update or a personal reminder, phone calls still carry unmatched urgency and human connection. But manually calling thousands of users?

That’s where Voice AI outreach steps in.

With Verloop.io’s Voice AI, brands can now run automated, intelligent outbound calls—at scale—without compromising personalisation or responsiveness.

Here’s why Voice AI on phone calls is a game-changer for outreach:

It’s direct and attention-grabbing

Let’s face it—people ignore emails and swipe away notifications. But a phone call? That gets attention. Voice AI makes it possible to reach customers in real-time, ensuring important messages—like payment reminders, appointment confirmations, or reactivation nudges—are actually heard.

It sounds human, not robotic

Verloop.io’s Voice AI doesn’t rely on pre-recorded IVRs. Instead, it uses conversational AI trained on real human speech. This means calls don’t just sound natural—they can understand responses, adjust tone, and follow context, making every interaction feel tailored, not templated.

Two-way conversations at scale

Outbound calls used to be one-way announcements. With Voice AI, you can create two-way voice flows where customers respond with natural speech, and the AI understands. Want to confirm a delivery slot? Collect feedback? Let users opt in or out?

All of this can be automated.

Cuts costs without cutting corners

Instead of hiring hundreds of agents for cold calls or follow-ups, Voice AI allows you to run thousands of intelligent outbound calls simultaneously, reducing operational costs by up to 40%—all while maintaining consistent quality and tone.

Measure what matters

Every Voice AI call is trackable. From call success rates to user responses, Verloop.io provides detailed call analytics so you can understand what’s working, tweak scripts, and optimise future outreach campaigns.

Works alongside WhatsApp

The best part?

You don’t have to choose. Verloop.io’s Voice AI works in sync with WhatsApp campaigns, allowing you to create multi-channel outreach journeys. Missed a WhatsApp message? Follow up with a call. Need to reinforce a voice message? Send a chat. It’s all connected.

Whether you’re looking to reduce no-shows, re-engage dormant users, or simply keep customers informed, Voice AI gives your outreach strategy a voice—literally.

Verloop.io Voice AI

When a customer picks up the phone, every millisecond counts. A delayed “hello” or robotic tone can instantly break trust. That’s why Verloop.io’s Voice AI is built with ultra-low latency, generative AI, and adaptive voice capabilities, delivering conversations that are fast, intelligent, and incredibly human.

This isn’t just another voice bot. It’s an AI agent that listens, understands, and responds, like your best support rep would.

Built for low-latency, real-time voice

Verloop.io uses ONNX-optimised Voice Activity Detection (VAD) and advanced audio stream processing to detect when a user starts or stops speaking in real time. Combined with efficient response generation, this enables sub-second turn-taking, so your customers never experience dead air or awkward overlaps.

Why does that matter?

Because nearly 18% of voice AI calls in India are dropped due to delays or poor experience. With Verloop.io, latency isn’t an issue—it’s an advantage.

Powered by Generative AI

At the heart of Verloop.io’s Voice AI lies generative AI trained on large language models (LLMs). This allows the agent to go beyond fixed flows or decision trees and instead:

• Generate natural responses on the fly

• Handle complex, multi-intent queries

• Personalise tone based on context and sentiment

• Recover gracefully from interruptions or ambiguous replies

The result?

Conversations that feel dynamic and empathetic, not robotic or pre-programmed.

Speech normalisation for real-world conversations

Accent?

Background noise?

Fast talkers?

No problem.

Verloop.io’s AI includes speech normalisation models that clean, clarify, and interpret speech inputs in noisy or imperfect conditions—ensuring accurate transcription and intent recognition across diverse geographies and voice patterns.

This means better understanding, fewer errors, and less need for customers to repeat themselves.

Speech profiles that adapt to your brand

Tone matters—especially on calls. With custom speech profiles, you can choose how your Voice AI sounds: energetic, calm, professional, or friendly. Whether you’re a bank confirming a loan application or a D2C brand nudging a cart abandonment, your AI agent will always sound on-brand.

And because the system is generative, it learns and adjusts over time, refining its tone, vocabulary, and delivery based on ongoing interactions.

Seamless multi-channel engagement

Voice AI doesn’t operate in isolation. It works hand-in-hand with Verloop.io’s chat and WhatsApp channels. You can create cross-channel journeys, like sending a WhatsApp message first, then placing a voice call if there’s no response, carrying over context across all channels.

Built-in intelligence and analytics

You don’t just get automation—you get insight. With Verloop.io, every call is logged, analysed, and translated into performance dashboards. Track metrics like:

• First-call resolution

• Call containment rate

• Drop-off points

• Response accuracy

• Sentiment trends

This lets you continuously optimise scripts, training data, and flows without flying blind.

If you’re looking to transform your outbound engagement with natural-sounding, AI-powered phone calls that convert, Verloop.io’s Voice AI is your go-to solution. Fast, flexible, and fully brand-aligned—it gives your outreach strategy a voice that truly connects.

How can your brand use proactive messages? 

Proactive messages can do wonders to enhance your customer engagement which in turn boosts your ROI. For instance, a Forrester study found that 40% of surveyed companies saw higher CSAT scores because of proactive communications. Additional benefits include:

• Reduction in call centre load 
• Improvement in agent productivity
• Increase in revenue
