Hello! As per your project post, you’re looking to extend your existing Acelle Mail and Postal infrastructure with a custom domain management and deliverability intelligence layer. From what I understand, the goal is to centrally manage 300 sending domains and 20 Postal nodes while automating warm up workflows, reputation monitoring, blacklist tracking, and intelligent domain rotation to maintain stable and predictable email delivery performance. My focus will be on delivering a custom Acelle integrated module featuring: domain and IP inventory management, hybrid warm up scheduler with approval workflow, reputation scoring engine, blacklist monitoring dashboard, bounce and complaint tracking, real time alerting, Postal node management, intelligent domain rotation logic, sending capacity allocation, performance analytics, and detailed deliverability reporting. I specialize in email infrastructure, Acelle Mail customization, Postal integration, PHP and Laravel development, automation systems, monitoring platforms, and scalable backend architectures. My focus will be on building a centralized control layer that provides visibility, automation, and operational safety while remaining flexible enough to support future infrastructure growth. Let’s connect to review your current Acelle and Postal architecture, warm up policies, deliverability requirements, and reporting expectations so we can design the most effective management system. Best regards, Nikita Gupta.

I have experience working with Acelle Mail, Postal, SMTP infrastructure, Laravel-based systems, and custom automation modules. I can develop a clean Acelle-integrated domain management solution that handles warm-up workflows, domain/IP rotation, reputation tracking, blacklist monitoring, and centralized management across your Postal cluster. My approach is to build the module with scalability and maintainability in mind, ensuring smooth integration with your existing environment while providing clear reporting, approval workflows, and monitoring dashboards. I can also provide deployment scripts, documentation, architecture updates, and a complete handover session. Available to start immediately and review your technical specification.

You have a solid setup with Acelle and Postal, and I’ll build exactly the glue you need to tie it all together. The warm-up scheduler will propose a ramp-up plan based on your rules, await your approval, then run automatically—giving you control without manual busywork. Blacklist monitoring will track complaints, bounces, and reputation in real time, sending alerts directly in the Acelle dashboard so issues get caught early. For domain rotation, I’ll create logic that balances sends evenly across your 300 domains and 20 Postal nodes, always factoring in warm-up status and reputation scores for each domain/IP pair. This means your campaigns stay safe, predictable, and scaled efficiently. I’ll deliver a clean plugin or source package that installs smoothly on your setup, plus easy-to-follow docs and updated architecture diagrams. If extra services are needed, I’ll include scripts (docker-compose or bash) for bootstrapping your VPS nodes. The final session will confirm the scheduler, blacklist alerts, and rotation all work as planned. Do you want the warm-up rules based on volume, engagement, or both? Also, how often should blacklist monitoring update to balance accuracy with system load? Ready to jump in and get this working for you fast.

Your rotation logic will fail if you treat all 300 domains equally - domains in warm-up cannot handle the same volume as established ones, and without per-domain throttling tied to reputation scores, you'll burn through IPs in the first week. Before architecting the module, I need clarity on two things: What's your current bounce rate threshold before you pause a domain, and are your 20 Postal nodes sharing IP pools or does each node have dedicated IPs? This determines whether I build rotation at the domain level or the IP level. Here's the architectural approach: - ACELLE PLUGIN ARCHITECTURE: Build a Laravel-based module that hooks into Acelle's campaign scheduler and injects rotation logic before each batch send, pulling real-time reputation data from Postal's API. - WARM-UP SCHEDULER: Implement a state machine that tracks each domain through 5 phases (10/day → 50/day → 200/day → 1K/day → full volume) with manual approval gates and automatic pause triggers if bounce rate exceeds your threshold. - BLACKLIST MONITORING: Set up cron jobs that query 15+ RBLs every 4 hours, parse Postal webhook logs for spam complaints, and push alerts to Acelle's notification system when any domain crosses into yellow/red zones. - ROTATION ENGINE: Use Redis to maintain a weighted queue where each domain gets a send-capacity score based on warm-up phase + last 24h bounce rate, then distribute batches proportionally across healthy domains only. - DOCKER ORCHESTRATION: Package the monitoring stack (Redis, cron container, log parser) as a docker-compose file that deploys to all 20 nodes with a single bash script. I've built 3 similar deliverability systems for SaaS companies sending 500K+ emails daily. Let's schedule a 15-minute call to walk through your Postal webhook structure and confirm your reputation thresholds before I start development.

Twenty Postal nodes means 20 separate rDNS records, 20 DKIM selectors, and 20 SPF includes that all need to align with the sending domains mapped in Acelle. When even a few nodes have mismatched PTR records or stale DKIM keys, ISPs correlate the whole cluster's reputation at the domain level, so inbox rates drop and it's not obvious which node is responsible. I'd run a DNS and auth audit across all 20 nodes first, then standardize Postal's config, set up Acelle's sending server pools with warmup-aware segmentation so cold IPs ramp separately from established ones, and dial in bounce and complaint thresholds per pool. Deliverable: all 20 nodes passing rDNS/DKIM/DMARC checks, Acelle routing configured for proper IP rotation and warmup control, and a runbook for adding nodes. Five days, 63,750 INR. Is Postal already installed on all 20 nodes, or does provisioning need to be part of the scope?

I don't understand what Acelle is, but I have cluster experience and have configured the entire Postfix suite. Perhaps communicating with me won't cost you anything. I will comprehensively assess your needs, and I will only issue a formal quote when I can provide you with a complete service. If you feel it's necessary, please contact me. Thank you! Also, I don't understand why you need so many domains and VPS for email. Please note, do not send spam.

⭐⭐Jaroslav Caprata - - - - - PHP & Email Infrastructure Developer⭐⭐ Hello, your Acelle and Postal environment is already well prepared, and I can help build the management layer needed to coordinate domains, servers, and deliverability controls efficiently. I have experience developing custom PHP modules, SMTP infrastructure integrations, Linux automation tools, and dashboard extensions for large-scale messaging platforms. For this project, I can create a clean Acelle-integrated module that manages domain rotation, warm-up workflows with approval controls, reputation-based sending decisions, blacklist monitoring, and balanced distribution across your Postal nodes. The architecture will remain modular so additional deliverability rules, monitoring sources, and domain-management features can be added later without major refactoring. I will provide well-documented source code, installation instructions, deployment scripts, architecture documentation, and comprehensive testing of all required workflows. Jaroslav Caprata is ready to review your technical specification and discuss the best implementation approach for a reliable, maintainable solution. I look forward to working with you.

⭐ Hi there ! Your Acelle + Postal setup needs a control layer that manages warm-up, reputation, and safe rotation without creating deliverability chaos. I built a self-hosted email system with Acelle, Postal, multiple SMTP nodes, bounce tracking, and domain-level sending rules. It handled 120+ sending domains with staged warm-up, complaint alerts, and automatic pause rules for risky domains. For your case, I can build a clean Acelle module for warm-up approval, blacklist checks, bounce/complaint monitoring, and rotation across 300 domains and 20 VPS nodes. I’ll also include clear setup docs, scripts if needed, and a walk-through test for each flow. The main thing is making sure the system doesn’t just “send more,” but sends predictably with limits, reputation checks, and proper suppression handling. Do you want the module built as an Acelle plugin, or is a separate dashboard connected to Acelle acceptable?
