Detailed Comparison by Category
Pricing and Transparency
One of the most significant differences between the two platforms is the pricing model.
Aurora Inbox offers a fixed price of $99 USD per monthclearly published on its website. This model allows SMBs to budget with certainty, with no billing surprises. There are no hidden costs for additional features or variable message volume fees (beyond the standard WhatsApp Business API costs).
Sirena/Zenviaon the other hand, operates on a model of customized prices that requires contacting the sales team to get a quote. This approach is common in platforms oriented to larger companies, but represents a barrier for SMBs that need to make quick decisions with defined budgets. Costs can vary significantly depending on the volume of conversations, number of agents and functionality required.
Verdict on prices: Aurora Inbox offers greater transparency and predictability, ideal for businesses that need to control costs. Sirena/Zenvia may be more flexible for large companies with specific needs, but the lack of price transparency makes initial comparison difficult.
Artificial Intelligence and Automation
Artificial intelligence is where Aurora Inbox makes a substantial difference compared to Sirena.
Aurora Inbox incorporates advanced AI agents they can:
- Answer customer questions autonomously 24/7
- Training with PDF documents of your company (manuals, catalogs, policies)
- Learning from URLs of your website to provide accurate and up-to-date answers
- Schedule appointments and manage calendars automatically
- Present products from the catalog when the customer enquires
- Transfer to a human agent when the situation requires it (human-in-the-loop).
Sirena/Zenvia offers basic automation focused on:
- Chatbots with predefined flows (decision trees)
- Simple automatic answers
- Automatic distribution of conversations
- Integrations with Zenvia's broader platform for campaigns
The fundamental difference is that Aurora Inbox uses state-of-the-art generative artificial intelligence that understands context and generates natural responses, while Sirena relies primarily on automation based on predefined rules and flows.
Verdict in IA: Aurora Inbox far surpasses Sirena in artificial intelligence capabilities, offering conversational agents that actually understand and respond like a human, versus rules-based chatbots.

Aurora Inbox offers a truly unique experience omnichannel:
- WhatsApp Business APIFull integration with all functions
- Facebook Messenger: unified management in the same tray
- TikTokemerging channel for capturing young leads
- Web Chatwidget that can be installed on any website
All channels are unified into a single inbox, allowing the team to manage all conversations from one place.
Sirena/Zenvia has its main strength in WhatsAppHistorically, it was one of the first platforms to offer WhatsApp Business API in Latin America. Through the Zenvia platform, SMS, email and voice are also accessed, although these channels work more independently and not always with the same unified experience.
Verdict in channels: Aurora Inbox offers a more cohesive and integrated multichannel experience. Sirena/Zenvia has strength in WhatsApp and access to traditional channels (SMS, voice) through the Zenvia ecosystem, but with less integration between them.

- Online registration without the need to contact a salesperson
- WhatsApp connection via QR code scanning or Business API

- Initial contact with sales team for quotation
- Onboarding process guided by an account executive
- Technical setup that can take days or weeks
- Longer learning curve due to the breadth of the Zenvia platform
- Support available but with origin in Portuguese (Brazilian)

What happens to Sirena now that she is part of Zenvia?
Since Zenvia acquired Sirena, the platform has been gradually integrated into the Zenvia ecosystem. This means that some customers have experienced changes to the interface, pricing structure and support.

Aurora Inbox represents a fresh alternative focused exclusively on the conversational AI experience for the LATAM market.
