What is SMTP Senpai?

MailSenpai's SMTP Senpai acts as a reliable SMTP relay for all your email needs, including sign-ups, password resets, order confirmations, notifications, and contact forms generated by your applications, websites, and tools. You can easily connect using standard SMTP on port 2525 or 587 with STARTTLS, a REST API that delivers JSON responses, or a specialized form endpoint that works seamlessly with web forms, even on static websites. All outgoing emails are authenticated with DKIM using your domain, and we provide the necessary DNS records while verifying them for you. We automatically manage bounced addresses, keep a comprehensive 90-day log of all sent emails, and deliver an in-depth weekly report for your records. Instead of suspending your account when you exceed a specific limit, we offer warnings and guidance on how to address any issues that arise. Our operations and servers are located in the EU, and we provide customer support in both Italian and English through ticketing and email systems. You can explore our offerings with a 14-day free trial that requires a credit card for registration (cancellation is available at any time), and after the trial, you can choose a subscription plan starting at €12.90 per month for up to 10,000 emails annually. With this service, you can enjoy dependable email delivery while benefiting from the flexibility and support tailored to enhance your communication requirements. Additionally, our commitment to data security and compliance further strengthens our service's reliability.

What is Fluxmail?

Fluxmail facilitates the seamless integration of AI agents and software tools with existing email accounts, whether using hosted or self-hosted environments. It supports a wide array of services, such as Gmail, Google Workspace, Microsoft 365, Outlook, Exchange, and various IMAP/SMTP mail servers. After users grant the necessary permissions, they can engage in activities like searching through their inboxes, reading and managing emails, downloading attachments, composing, sending, or forwarding messages, and organizing their mail with labels and folders. This extensive functionality is enabled by an MCP server specifically designed for compatible AI clients, along with a REST API that serves multiple applications and scripts, and a command-line interface that offers additional versatility. Cloud users can authenticate through OAuth, while those who prefer self-hosted setups can configure their systems using npm or Docker, ensuring that their credentials remain securely encrypted on the host. Additionally, permissions for mailboxes and actions are customizable, allowing for configurations such as read-only access. Ultimately, Fluxmail is designed to serve developers, agent creators, and anyone interested in enhancing their email experience with AI support. By leveraging this adaptable tool, users not only optimize their email management but also empower themselves to utilize artificial intelligence for more effective communication in their everyday lives, thus revolutionizing the way they interact with their emails.
