Blip vs Zenvia vs Sailer AI: communication platform or sales platform?

Blip vs Zenvia: both are communication platforms for large brands, built for bots, customer service and high-volume messaging. Blip stands out in conversational journeys for large accounts; Zenvia in multichannel messaging with SMS and RCS and public plans. Sailer AI is a different category: a CRM with AI agents and seller governance, built for sales.

Sailer wrote this comparison, so we tried to be especially fair. Blip and Zenvia data comes from each company's own website, checked in October 2026, and may change. In several scenarios Blip or Zenvia is the right call, and we say which.

Blip vs Zenvia vs Sailer AI at a glance

What Blip is

Blip is the former Take Blip, renamed in June 2023. It serves large companies in retail, financial services, telecom, education and energy, and says it processes more than 20 billion messages a year. Customers named on its site include Itaú, Bradesco, Claro, Stellantis and Energisa.

The platform organizes the customer journey into stages (listen, attract, convert and engage) and offers AI agent building, a copilot for human agents, in-conversation payments and its own chat channel. It is an official Meta Business Solution Provider. For small businesses, the company offers Blip Go, which adds an AI agent, a kanban pipeline and campaigns to an existing WhatsApp Business number through coexistence.

What Zenvia is

Zenvia sells Zenvia Customer Cloud, a customer experience suite that brings together channels, data and automation, and says it has more than 10,000 customers. Anyone looking at Zenvia for WhatsApp finds an official Meta partner (BSP) that connects numbers through the official API, lets several agents work from one number and offers coexistence to migrate from the regular app while keeping the number.

On AI, Zenvia's bet is orchestrating Meta Business Agent, Meta's own agent launched in 2026. Its site puts it plainly: the intelligence is Meta's, the operational brain is Zenvia. Beyond WhatsApp, Zenvia offers SMS, RCS, email and voice, plus more than 20 native connectors, including Salesforce, Zoho and RD Station Marketing.

Blip vs Zenvia: where each one shines

If you are choosing between the two, the practical differences are:

• Blip is stronger with large accounts running complex conversational journeys: flow-designed bots and agents, high service volume, in-conversation payments and a long track record with banks and telecoms. Base monthly prices aren't shown on the site; Enterprise is quoted on request.
• Zenvia is stronger in multichannel messaging, especially SMS and RCS next to WhatsApp, and it has a ladder of public plans that starts free. Channel usage is billed separately in packages.
• Both were designed for a brand to talk to many customers through company numbers and agent queues. Service and communication at scale are the core. Consultative selling with a book of accounts per rep is not.

How Sailer AI is different

Sailer AI is a CRM and AI agent platform for WhatsApp sales: it connects the brand's numbers and each seller's own number to the official API, puts AI agents and people in the same team inbox, fills in the CRM on its own and measures every conversation. The difference from Blip and Zenvia isn't having WhatsApp or AI. It's what sits at the center.

The CRM at the center, not on the side

In Blip and Zenvia, the CRM is an external system to integrate. In Sailer, the deal is the main object: the conversation creates and updates the contact and deal, moves the pipeline stage and records the loss reason. If you run Salesforce or HubSpot, Sailer reads contact, account and opportunity context, writes fields and notes, moves stages and syncs account ownership. See the platform and the Salesforce integration.

AI agents that sell

Crew agents were built to run a sale: qualify, handle objections, book, close and hand off to the right person with context. Every change runs in a sandbox before it reaches a customer. At Amor Saúde, AI scheduling and cross-selling of the Cartão de Todos card reached 24% scheduling conversion and 28% card conversion, with the cost of serving each lead down 66%. More on the WhatsApp AI agent page and in the Amor Saúde case.

Each seller's number under governance

Many companies sell through each rep's own WhatsApp, not a central number. Fleet connects those numbers to the official API with coexistence, gives each one an owner and a book of accounts, sends campaigns from the owner's number and keeps history and an audit trail when someone leaves. At Arco Educação, 125 of 135 consultants joined in two months, sending 16,500 messages from their own numbers with a 26% reply rate.

A Blip or Zenvia alternative: when switching makes sense

Switching makes sense when the problem is sales, not communication. The usual signs:

• WhatsApp became a consultative sales channel, but the pipeline lives outside the platform and the CRM isn't updated.
• Bots answer questions but don't qualify, handle objections or book meetings.
• Reps use their own numbers and the company has no visibility or campaigns per book of accounts.
• Managers can't measure conversation quality beyond a sample.

You don't always need to switch. Many companies keep Blip or Zenvia for customer service and run Sailer in the sales operation, with the CRM as the meeting point.
