Description

Ha Tang serves as a comprehensive platform for customer support, email, and payment solutions tailored for Vietnamese enterprises and software development teams. It consolidates various communication channels, including Zalo (both Official Account and personal), Facebook Messenger, Instagram, TikTok, WhatsApp, email, and live chat functionalities on websites and mobile applications, into a single shared inbox. The platform utilizes an AI assistant that leverages the organization's knowledge base, adheres to situational protocols, prepares order drafts, and efficiently transfers chats to human representatives when necessary. Additionally, it facilitates VietQR bank transfers by linking them to specific orders and generates electronic invoices upon payment completion. Its email functionality allows for transactional message delivery via a REST API and SMTP, including features such as domain verification, inbound email management, and team group support. Developers are provided with extensive tools, including REST APIs, webhooks, and SDKs for Node, Flutter, iOS, and Android, as well as an MCP server for enhanced functionality. Agents can operate seamlessly through a user-friendly web dashboard and native applications optimized for iOS, Android, and macOS, ensuring a versatile experience for both users and developers alike.

Description

SMTP Senpai, offered by MailSenpai, serves as the SMTP relay for emails generated by your applications, websites, and tools, handling everything from sign-ups and password resets to order confirmations, notifications, and contact forms. You can connect using standard SMTP (port 2525 or 587 with STARTTLS), a REST API that provides JSON responses, or a dedicated form endpoint suitable for web forms, even on static sites. All outgoing emails are DKIM-signed using your own domain, for which we supply the necessary DNS records and verify them on your behalf. Automatically, we suppress bounced addresses, maintain a 90-day log of all sent emails, and provide you with a comprehensive weekly report. Rather than suspending your account upon exceeding a certain threshold, we issue a warning and guide you on what needs to be addressed. Our servers and data operations are based in the EU, and we offer support in both Italian and English through tickets and email. Try us out with a 14-day free trial that requires a card for registration (you can cancel anytime), and then continue with plans starting at €12.90 per month for up to 10,000 emails on an annual subscription. This service ensures reliable email delivery while offering flexibility and support for your communication needs.
