Respond.io alternative for businesses

Respond.io alternative for WhatsApp Business API Solution Provider

Social messaging apps are now granting businesses the power to remain competitive. Other than cultivating customer loyalty in the long run, chatting with customers helps businesses build real connections and drive sales by transforming conversations into conversions.

3.09 billion smartphone owners access messaging apps for communication. 90% of consumers prefer to be contacted via messages. As people grow fond of chatting online, they use it not just with families and friends but also with businesses.

All this explains the rising popularity of messaging platforms such as Respond.io, where businesses unify customer communications to ease work operations. Nevertheless, to maximize revenue and minimize expenses, business owners must always explore better WhatsApp Business API options available on the market.

If you still don’t know where to start, here’s a Respond.io alternative as your starting point!

Respond.io vs SleekFlow: what we offer as the best WhatsApp Business Solution Provider (BSP)

Respond.io and SleekFlow have significant similarities regarding the services and features provided. Although Respond.io looks cheaper at first glance, the features are actually limited.

SleekFlow is a Meta partner for business messaging

As opposed to Respond.io, SleekFlow offers an omnichannel platform with comprehensive features, a sufficient number of contacts, flexible add-ons, and more to accelerate sales, boost conversions, and reinforce customer support with seamless workflows.

So, which should you really choose? Read on to find out. 

Assigning conversations to multiple users instead of one

Contacts can be assigned to only one agent on Respond.io. On the other hand, SleekFlow users can have up to 5 collaborators aside from the agent owning the chat, ensuring that each customer receives necessary assistance and accurate information as soon as possible as relevant departments or employees can attend to inquiries whenever needed.

Collaborator tools

Besides that, SleekFlow has incorporated handy little details such as displaying agent names in chats for the ease of customers, scheduling messages right in the reply section, setting your online status to ‘active’, and more.

Extra customer contacts: the more, the better

Having the number of customer contacts restricted to 100 is common for the free plans, but SleekFlow has pushed open doors to assist businesses by allowing 2,000 and 10,000 customer contacts for Pro and Premium Plan users. As for Respond.io, they supply 1,000 and 3,000 Monthly Active Contacts (MAU) for the equivalent tiers.

*MAU refers to contacts that have sent or received texts from your business, excluding broadcast messages, in a single month. You have to pay Respondio a rather pricey amount for each 100 MAU over the limit.

Depending on the size of your business, choosing the appropriate plan is critical to optimizing the budget for a higher ROI. If your company has a larger client base, you should definitely go for a premium solution with extra contacts for highly efficient operations.

Although Respondio labelled their total contacts excluding MAU as unlimited, the storage of contacts is actually limited to 20x of your MAU limit. For example, if you're on their Team Plan with 1,000, you can only have 20,000 total contacts. It is not unlimited.

WhatsApp for marketing WhatsApp catalog

If you're struggling to get commerce features to support your sales teams on Respondio, you can find them on SleekFlow. As leads come in from various messaging channels, your team can attach the in-chat catalog for them to browse through the latest collection of products or services.

Once the prospective customers finish inquiring and decides to make a purchase, your salesperson can instantly generate and send a payment link for them to complete orders right in the chat.

Broadcast messages with simpler steps

On Respondio, you will need to add contacts to Segments for broadcast campaigns. These segments are groups of contacts you gather with labels you create. In the case where someone in your team accidentally deletes the label, your contact will be automatically removed from the segment. As a result, there might be contacts that are missed out when you send messages in bulk.

Create contact lists on SleekFlow

On SleekFlow, you can easily add contacts to lists for broadcast campaigns. Even if a label is not added, the contacts can be consolidated into organized lists.

Free onboarding support for the official WhatsApp Business API

On Respond.io, the analytics are separated into different reports. Their users can only review the activities of their agents, message performance, and other metrics. Conversations are managed like tickets.

SleekFlow analytics contains all those elements, accompanied by other additional metrics such as delivery rate, bounce rate, read rate, and reply rate for the campaigns created. You can even compare two segments at a time!

Unified CRM to convert prospects with accelerated speed to lead

Automated responses are useful to reduce the loss of leads and drive conversion as customers are provided with the answers at once. You can also customize automated workflows on Flow Builder to guide customers smoothly down the marketing and sales funnel.

And as we all know, happy customers share their experiences with others. That’s free marketing!
