    Users can easily set up email addresses with their own custom domain names, enhancing brand professionalism and consistency.

Possible disadvantages

  • Limited Brand Recognition
    As a newer or lesser-known provider compared to Google Workspace or Microsoft 365, StackMail may lack the trust and reputation that larger providers have established.
  • Fewer Third-Party Integrations
    Compared to major email service providers, StackMail may offer fewer integrations with third-party apps and services, limiting its versatility for some businesses.
  • Limited Advanced Features
    It may not offer the same breadth of advanced productivity and collaboration tools that come bundled with larger platforms like Microsoft 365 or Google Workspace.
  • Smaller User Community
    Due to a smaller user base, there may be fewer community resources, third-party tutorials, or troubleshooting forums available online.
  • Uncertain Long-Term Support
    As a smaller company, there might be concerns regarding the long-term viability, updates, and continued support of the service compared to more established providers.
  • Viber, WhatsApp and SMS
    All three channels on one platform, one contract and one bill, with Viber delivered directly as an Official Rakuten Viber Messaging Partner.
  • Automatic SMS failover
    Messages that cannot be delivered on Viber or WhatsApp are re-sent as SMS automatically, with nothing to configure.
  • Customer segmentation
    Segments from any contact list by attributes, tags and reaction to past campaigns, plus purchase-based segments when a store is connected.
  • Personalisation
    Variables reach text, images, links, button labels and every Viber carousel card, so one campaign becomes thousands of individual messages.
  • AI-assisted content
    Campaign copy and visuals generated inside the platform in seconds.
  • Transactional messaging API
    OTP and 2FA codes, order updates, payment reminders and service alerts triggered from any system through one REST API.
  • eCommerce automation flows
    Pre-built cart recovery, second purchase, post-purchase upsell, win-back and back-in-stock flows, triggered by connected store data.
  • Analytics and ROI tracking
    Delivery, opens, clicks and cost on every campaign, plus revenue, orders, AOV and cost per sale when sales data is connected.
  • Shopify, WooCommerce and Magento
    Native store integrations that bring customers, orders and catalogue into segmentation, recommendations and revenue tracking.
  • Lead Generation Forms
    Opt-in forms that grow a consented messaging audience from people you already reach.

Questions & Answers

As answered by people managing StackMail and Abelo.

Who are some of the biggest customers of your product?

Abelo's answer:

Abelo works with online retailers and enterprises across retail and eCommerce, financial services, logistics and insurance. Customer names are shared with their permission on request.

What makes your product unique?

Abelo's answer:

Abelo is both the messaging provider and the intelligence layer. Businesses usually have to choose between a provider that delivers messages but cannot target or measure them, and a marketing tool that relies on someone else's delivery. As an Official Rakuten Viber Messaging Partner, Abelo delivers Viber messages directly under the business's own verified name, and builds segmentation, personalisation, automation and ROI tracking on top. Personalisation reaches the image, the button and every card in a Viber carousel, not just the text. Promotional messages triggered through the API report as named campaigns, with the same tracking as campaigns sent from the platform. Delivery and intelligence, on one contract.

Why should a person choose your product over its competitors?

Abelo's answer:

Because most messaging platforms stop at "delivered". Abelo shows what each campaign earned: revenue, orders and cost per sale tracked to every campaign and automated flow when sales data is connected, plus delivery, opens, clicks and cost on everything. It's an Official Rakuten Viber Messaging Partner, so Viber messages go out directly with no reseller in the chain, and anything that can't be delivered on Viber or WhatsApp is re-sent as SMS automatically. Marketers launch campaigns without a developer, developers trigger messages through one REST API, and online stores on Shopify, WooCommerce or Magento switch on pre-built revenue flows instead of designing them. One platform, one contract, one bill.

How would you describe the primary audience of your product?

Abelo's answer:

Two groups. Marketing and eCommerce teams at retailers and online stores, such as CMOs, CRM managers and eCommerce directors, who use Viber, WhatsApp and SMS to turn their customer base into more orders. And digital, IT and operations teams at enterprises such as banks, insurers and logistics companies, who depend on messages that must arrive: one-time passwords, transaction alerts, delivery updates and payment reminders. Both use the same platform: marketers through the web app, developers through the API.

What's the story behind your product?

Abelo's answer:

Abelo is built and owned by Trebbble, a design and engineering company that has shipped mobile and digital products for banks, telecom operators and energy providers since 2010, and has always been self-funded. Abelo started as VibeCart, a Viber marketing platform for online stores. Building it, the team saw the same gap again and again: businesses had to choose between a messaging provider that delivers but can't measure, and a marketing tool that measures but rents someone else's delivery. In July 2026 VibeCart became Abelo, and Abelo became an Official Rakuten Viber Messaging Partner. The platform now covers transactional messaging and enterprise use cases as well as eCommerce, across Viber, WhatsApp and SMS.

Which are the primary technologies used for building your product?

Abelo's answer:

Abelo is a cloud-based SaaS platform with a REST API and webhooks, documented at docs.abelo.ai. It connects natively to Shopify, WooCommerce and Magento, and delivers Viber messages directly as an Official Rakuten Viber Messaging Partner. Built by Trebbble's in-house engineering team, with enterprise-grade security and GDPR compliance.
