360dialog is a specialized messaging platform that gives you direct access to the WhatsApp Business API. Instead of using a basic app, you can connect WhatsApp to your CRM, helpdesk, or marketing tools to manage high-volume conversations. You can send automated notifications, provide real-time customer support, and launch marketing campaigns while maintaining official verified status. The platform focuses on providing a stable, low-latency connection that handles millions of messages without technical friction. You can manage your phone numbers, templates, and compliance requirements through a centralized dashboard. It is designed for businesses that want to own their customer relationships on WhatsApp while using their preferred third-party software for the actual chat interface.

Mailsuite (formerly Mailtrack) is a specialized email tracking tool designed specifically for Gmail users who need to know exactly what happens after they hit send. You can see real-time notifications the moment your recipient opens an email or clicks a link, allowing you to time your follow-ups perfectly. It integrates directly into your existing Gmail interface, so you don't have to learn a new platform or switch between different tabs to manage your communication. Beyond simple tracking, you can send personalized mail merges to multiple recipients and set automated reminders for emails that haven't been opened. It is ideal for sales professionals, recruiters, and small business owners who rely on Gmail for their daily operations. You can start with a free version for basic tracking or upgrade to access advanced features like document tracking and ad-free signatures.
