Vonage WhatsApp Inbox: Why Use Respond.io
In this section, we'll discuss how to start messaging with Vonage WhatsApp API. Because the API is just a pipe that transmits information to and from WhatsApp's network, it does not come with a messaging interface.
Why You Need a Vonage WhatsApp Inbox
This means there is no place to easily answer WhatsApp messages unless you connect your WhatsApp API account to a third-party WhatsApp Inbox like respond.io.
You may be inclined to connect your Vonage WhatsApp API account to your company CRM just like you would with email. While conventional CRMs like Hubspot or Salesforce are great for managing customer information, they lack proper messaging features.

Because of that, most agents prefer to send and receive emails directly from Gmail or Outlook, even though their emails are connected to a CRM.
Unlike CRMs, a Vonage WhatsApp Inbox like respond.io is designed to help you manage messaging conversations. Respond.io comes with full-fledged messaging features such as Comments and Snippets, allowing agents to collaborate and respond faster.
A Vonage WhatsApp Inbox is great for messaging customers via WhatsApp, but what about other Channels?
Delight Customers with Multichannel Capability
Going multichannel gives customers the flexibility to contact you however they want, which builds customer loyalty. Here are some examples of how the multichannel approach makes things easier for your customers.
Some channels work better in certain settings. For instance, your customers may prefer contacting you with email over WhatsApp at work. By offering email as an alternative contact channel, you are well on your way to gain loyal customers!
Here’s another instance where multichannel capability comes in handy. WhatsApp may work great for customers on the go, but not for those on your website. Offering web chat in addition to WhatsApp makes it easier for customers to contact you wherever they are.

Going multichannel makes your customers' lives easier, but increases the workload of agents and salespeople. They have to juggle different platforms, respond to customers on one platform while checking for incoming messages on another platform.
The multichannel approach has another drawback. When someone contacts you on two different platforms, it's hard to understand customer context because the conversation becomes siloed.
Imagine this scenario: a salesperson had a long conversation with a customer on WhatsApp and promised him a special deal. But when the customer comes in on web chat, this looks like a new chat to the Support agent who knows nothing about the deal.
Respond.io helps overcome these challenges, letting you adopt omnichannel the easy way and understand customer context better with Contact Merge.
Make Agents Lives Easier With Omnichannel Capability
Looking to use multiple channels but don't want to burden your Sales and Support team?Respond.io is the perfect omnichannel solution for you. It allows managing conversations from different Channels in one unified platform.
Respond.io supports all the popular channels, including mainstream apps like WhatsApp, Messenger, and Instagram. It also supports niche messaging apps such as Telegram, Viber, WeChat and LINE, which are popular in certain countries.

And did we mention, respond.io supports email and web chat too. You can manage email and web chat conversations on respond.io along with messaging apps as part of the omnichannel strategy.
To go truly omnichannel, consider Contact Merge. Contact Merge integrates chats with the same customer across different channels, giving you a clearer picture of what's going on.
Break Down Silos and Understand Customer Context With Contact Merge
By providing context to conversations, Contact Merge empowers your Support team to respond more empathetically to customers. Agents can simply scroll up to review conversations that took place on different channels.
With Contact Merge, the Support agent in the previous example can easily find out the promise made to the customer by the salesperson over WhatsApp and deliver the right response.

Merging Contacts on respond.io is simple, you can merge chats with a Contact from different Channels into one unified profile and conversation with just a few clicks. Connect your Vonage WhatsApp API to respond.io to experience the power of Contact Merge. To get started, create a free respond.io account.

Respond.io With Vonage WhatsApp integration: 6 Quick Wins To Get You Started
Respond.io with Vonage WhatsApp integration works for all use cases and workflows. However, we will start with six quick things you can do to get the best out of your Vonage WhatsApp Inbox.
1. Import or Sync WhatsApp Contacts To Respond.io With Vonage WhatsApp Integration
Whether you want to reach out to a prospect or send proactive notifications to your customers, the first step to using a Vonage WhatsApp Inbox is always importing contacts.

Importing Contacts to respond.io is a breeze because you can import single or multiple Contacts by uploading a CSV file. You can even sync Contacts on the fly with Contacts API. Once done, you are ready to connect with your Contacts. If you want to connect with more customers, consider Click-to-WhatsApp Ads.
2. Run a WhatsApp Marketing Campaign With Click-to-WhatsApp Ads
Click-to-WhatsApp ads let you connect with leads without having to request their contact information. When clicked, Click-to-WhatsApp ads take leads right to the WhatsApp conversation. You can message them back if they send the first message.

WhatsApp campaigns will inevitably increase the incoming message traffic and it will be challenging to handle a high volume of messages in an organized manner. This is where Contact Assignment comes in.
3. Assign Contacts to Multiple Agents
Contact Assignment helps your Sales team stay organized, even with a high volume of incoming messages. There are two ways to assign Contacts on respond.io, which are Picking and Auto Assignment.

The Picking method works great for smaller businesses. It let agents manually assign a pending Contact to themselves or others. If you are flooded with messages, turn on Auto Assignment and Assign to Online Users Only to ensure prompt responses.
If you have a lot of website visitors, you can set up a contact form and use Vonage WhatsApp Inbox to reach out to them.
4. Reach Out to Prospects Who Filled Out a Contact Form
WhatsApp is an effective way of reaching out to prospects who submitted a contact form. They are more likely to respond because they’ve expressed their interest first by filling up their details. You can start a WhatsApp chat by sending a Template Message.

But first, you need to create a Template Message on Vonage. Once approved, import the Template Message to respond.io and you are ready to send the first message to prospects.
You can continue the conversation if customers reply. Salespeople may not be able to respond right away because they aren’t always deskbound. We’ve created a mobile app for your Sales team to answer messages on the go.
5. Respond to Inbound Messages from the Mobile App
The respond.io mobile app lets you respond to incoming messages on the go. It's complete with Dashboard, Contacts, Messages & Settings modules which makes it easy to answer messages and add teammates from the app.

You’ll receive a new notification every time a new message comes in. With push notifications, agents won't miss any message even when they are away from the desk. Download the Android & iOS apps from Google Play Store & Apple App Store.
Other than having 1:1 conversations, a Vonage WhatsApp Inbox also lets you send messages en masse. This is useful for sending important updates like a scheduled maintenance announcement.
6. Send Proactive Notifications With Vonage WhatsApp Inbox
WhatsApp Notifications are more likely to be read because they trigger push notifications that are hard to ignore. Respond.io lets you schedule a broadcast notification and even select your audience to send notifications to.

Before sending WhatsApp Notifications, you should collect opt-in from your customers. Customers may block you if you spam them with unwanted messages, which affect your Quality Rating.
