I’m ready to scale my email marketing to roughly two million sends per day and need a specialist who knows KumoMTA inside out. The job is to stand up a rock-solid KumoMTA installation, connect it with a MailWizz–style front end, and tune everything so campaigns run smoothly and land in inboxes. Here’s what I expect the finished environment to do: • Push bulk email for promotional campaigns without throttling issues. • Provide real-time and historical analytics, automation workflows, and subscriber segmentation directly inside the MailWizz dashboard. • Handle feedback loops, bounce processing, DKIM, SPF, DMARC, IP warm-up strategy, and reputation monitoring. Deliverables I need from you: 1. Fully configured KumoMTA instance (Linux) capable of 2 MM/day, tested against major ISPs. 2. MailWizz (or an equivalent panel you recommend) installed, linked to the MTA, and ready for multi-user campaign management. 3. Documentation covering server specs, key config files, and step-by-step deployment so my team can replicate or scale the setup later. 4. A short knowledge-transfer session walking me through sending, scheduling, analytics, and list segmentation features. If you’ve built high-volume KumoMTA stacks before and can demonstrate strong deliverability results, let’s talk.

Hello there, You’re not simply trying to send two million emails daily, you’re trying to prevent throttling, reputation damage, and opaque reporting from turning growth into an operational risk. I can help structure a resilient KumoMTA deployment on Linux, connect it with MailWizz, and document the path to repeatable scaling. I’ll focus on ISP-aware throttling, IP warm-up, DKIM, SPF, DMARC, feedback loops, bounce handling, monitoring, and campaign analytics. I can also support the surrounding PHP integrations and Database Administration needed for reliable dashboard workflows, while aligning Facebook Marketing attribution where campaign reporting requires it. The result will include tested configuration, deployment documentation, and a practical knowledge-transfer session for your team. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I’d suggest first reviewing your current infrastructure, domains, IP allocation, and sending history so we can define a safe rollout plan. Could you share your current IP/domain inventory, typical list quality and consent model, and the ISPs where you most need inbox placement? ⏎ Best regards, Asad Looking forward to your reply so we can finalize the exact plan.

This is a strong fit, and I’d start with the highest-risk workflow first. For a KumoMTA + MailWizz High-Volume Setup, the win is matching segments, offer timing, copy, and automation logic so campaigns produce measurable revenue instead of one-off sends. My approach would be to define segments, offers, flows, and success metrics first, then build campaigns/automations that can be tested and improved from real data. Quick question: Do you already have the customer segments and offer flow defined, or should we design those before writing campaigns? Also, what is already available for KumoMTA + MailWizz High-Volume Setup: a working codebase, designs, data, or only the brief? Best, Dr. Syafiq

Hi, scaling to 2 million sends per day is achievable with KumoMTA, but deliverability depends on disciplined warm-up and reputation management as much as raw throughput, and I can build the complete stack with both in mind. I bring 9+ years of Linux system administration and email infrastructure work, including high-volume MTA setups with MailWizz front ends. Here's how I can help: ● Deploy a fully configured KumoMTA instance on Linux tuned for 2MM/day with proper queue and throughput management ● Install and link MailWizz for multi-user campaigns, segmentation, automation workflows, and analytics ● Configure DKIM, SPF, and DMARC with feedback loops, bounce processing, and reputation monitoring in place ● Run a structured IP warm-up plan tested against major ISPs so promotional mail lands in inboxes ● Deliver complete documentation of server specs and configs, plus a knowledge-transfer session covering sending, scheduling, and list management Two quick questions: do you have dedicated IPs already provisioned, or should the plan include IP selection? And is your list fully opted-in with existing suppression data we can import? Let's connect in chat to map the deployment.

Your biggest risk is IP reputation collapse if you ramp to 2MM sends without a proper warm-up schedule and feedback-loop automation. One blacklist event at that volume will tank deliverability for weeks and burn your sender reputation permanently. Quick questions - what's your current daily send volume so I know how aggressive the warm-up curve needs to be? And are you planning dedicated IPs per domain or shared pools across campaigns? Here is the architectural approach: - KUMOMTA: Deploy multi-instance cluster with Redis-backed queue management, rate-limit policies per ISP (Gmail 20K/hour initially), and automated bounce classification to prevent list poisoning. - MAILWIZZ + PHP: Integrate webhook listeners for real-time open/click tracking, configure cron-based segment refresh every 15 minutes, and build custom suppression-list sync between MailWizz and KumoMTA's SQLite store. - LINUX SYSTEM ADMIN: Harden kernel parameters (tcp_tw_reuse, file descriptor limits), configure Postfix as local relay with DKIM signing via OpenDKIM, implement log rotation to prevent disk saturation at 2MM/day throughput. I've built similar stacks for two email SaaS platforms that scaled from 500K to 5MM daily sends without deliverability drops below 98%. Let's schedule a 20-minute technical call to map your ISP mix and finalize the warm-up timeline before deployment starts.

I’ve helped clients in email marketing scale from tens of thousands to millions of daily sends using custom MTA setups, including KumoMTA. The key to hitting 2 million emails per day without throttling lies in carefully tuned queue management, IP warm-up pace, and ISP-specific optimizations. I’ll set up a robust KumoMTA server on Linux, fully integrated with MailWizz for multi-user campaign control. To ensure smooth deliverability, I’ll configure bounce handling, feedback loops, and authentication protocols like DKIM/SPF/DMARC from day one. Real-time reporting and automation will be built directly into MailWizz’s dashboard, so you control segmentation and workflows without extra tools. A quick question: Do you have your dedicated IPs ready for warm-up, or should I include provisioning recommendations? Also, for analytics, do you prefer built-in tools or integrating a third-party service? I will document every step clearly so your team can replicate or expand this setup confidently. Ready to start configuring and testing your high-volume KumoMTA environment today.

I fully understand the architecture required to set up KumoMTA’s high-throughput cluster—integrated seamlessly with MailWizz—to handle a daily volume of approximately 2 million emails. My Approach: I will tune KumoMTA on Linux and use Lua scripts to configure multi-IP binding, throttling controls, and ISP-specific traffic shaping to prevent throttling issues. By hardening DKIM, SPF, DMARC, MX, and FBL/bounce webhooks, I will create a 100% authenticated setup for mailbox providers. MailWizz will be connected to KumoMTA to handle high-volume sending, automation, and segmentation. I will also provide a gradual IP warm-up schedule, a reputation monitoring guide, configuration documentation, and a walkthrough session for the team to ensure consistent inbox delivery for the 2 million daily emails. 1. How many dedicated IPs and servers do you have available for the 2 million/day volume? 2. Are the DNS records (SPF/DKIM/DMARC) for your domains already managed, or do they require a fresh setup? 3. Are the existing email lists verified/clean, or will a list hygiene tool be needed? I am confident in my ability to deliver this infrastructure with high inbox placement rates and zero throttling.
