I need a ready-to-use bulk email program that installs on Windows and comfortably pushes out up to 20 000 cold emails every day. Consistent inbox placement is critical, so the solution must sustain at least 70 % deliverability and handle standard cold-outreach needs such as warmed-up SMTP rotation, throttling controls, DKIM/SPF configuration and automatic bounce processing. Full, real-time analytics are a must: I have to see open rates, click-through rates and unsubscribe rates at minimum, along with spam-complaint flags so I can quickly prune lists. Personalisation isn’t required—plain text blasts are fine—but clean list uploading, suppression management and simple template storage will help keep campaigns organised. Because I’m ready to purchase as soon as it proves itself, I’ll need a trial or test licence long enough to push a live batch and confirm deliverability and reporting accuracy. Deliverables (acceptance criteria) • Windows installer or portable executable of the application • Trial credentials or licence key sufficient for one full test campaign • Brief setup guide covering SMTP integration, DNS settings and analytics dashboard • After successful test, link or invoice for the full commercial licence If you already have a mature, battle-tested Windows solution that ticks these boxes, let’s talk so I can start testing right away.

Hello, I can provide or develop a Windows-ready bulk email application aligned with your acceptance criteria: a portable executable or installer, SMTP rotation with throttling, DKIM/SPF setup guidance, automatic bounce processing, suppression management, plain-text templates, and campaign analytics for opens, clicks, unsubscribes, and spam complaints. The solution can be structured for a controlled live trial, allowing you to validate throughput, inbox placement, reporting accuracy, and list hygiene before purchasing a commercial licence. I’ll also ensure the setup guide clearly explains SMTP integration, DNS records, campaign configuration, and dashboard usage. My Software Development approach will focus on reliable operation at your target volume and maintainable Windows deployment, while the Email Marketing workflow supports practical cold-outreach administration. Could you confirm which SMTP providers and Windows versions you want supported for the live trial, along with how you will measure the 70% deliverability target? I’m ready to review whether you already have an existing mature product to deploy or need a tailored Windows implementation, then define the trial scope and success metrics. Regards, Muhammad Awais

Hi, I understand you're looking for a mature Windows-based bulk email solution with SMTP integration, throttling, bounce processing, suppression management, campaign analytics, and a simple workflow for managing lists and templates. I can help evaluate or configure a solution around these requirements, including SPF/DKIM setup, SMTP integration, controlled sending, bounce and unsubscribe processing, list hygiene, and reporting for delivery, opens, clicks, and complaints. For the trial, I’d recommend validating the actual sending infrastructure and reporting with a controlled test campaign before committing to a commercial license. I would also avoid guaranteeing a fixed inbox-placement percentage, since deliverability depends on sender reputation, domains, recipient lists, mailbox providers, content, and sending practices. If you can share your preferred sending provider/SMTP setup and the approximate test volume, I can confirm the most suitable solution and trial approach.

Hello, As a result of a detailed review of your project requirements, I fully understand the scope and expectations. I have experience with software development, email systems, SMTP integrations, analytics, and Windows application workflows. I can help deliver a Windows-based bulk email solution focused on reliable campaign management, including SMTP configuration, sending controls, list management, bounce handling, suppression management, templates, and reporting features. The main focus will be building a stable application architecture that supports large campaign volumes while maintaining proper email infrastructure practices. I would include configurable SMTP rotation, throttling controls, DNS guidance (SPF/DKIM), campaign tracking, and a simple dashboard for monitoring opens, clicks, unsubscribes, and delivery issues. I would first validate the existing requirements through a controlled test campaign, then provide the installer/executable, setup documentation, and licensing process after successful verification. A couple of quick questions: • Do you already have SMTP providers/accounts available, or should the system support configurable providers? • Do you need integration with any existing contact database or CRM? I’m available to discuss the technical approach and help prepare a solution that is reliable and easy to operate. Best regards, Carlos.
