Etechinvest designs, deploys, and maintains the SMTP infrastructure behind high-volume email programs. With 8+ years of hands-on experience managing PowerMTA deployments, MailWizz installations, and deliverability crises for agencies and direct clients across multiple industries, we configure every server for maximum inbox placement — not just maximum throughput.Every infrastructure engagement starts with the fundamentals: SPF, DKIM, DMARC, and rDNS configured correctly across every sending domain before the first message goes out. Bounce handling rules, IP rotation logic, and sending domain separation are planned at the architecture stage — not retrofitted after problems appear. A structured IP warm-up plan is built for every new deployment, with monitoring in place from day one so reputation issues are caught before they affect campaign performance.We work with agencies running cold outreach at scale, SaaS platforms sending transactional email, and e-commerce businesses managing high-volume promotional campaigns. Whether you need a single-server PowerMTA setup sending 100K emails per month or a multi-IP architecture handling 5M+ monthly sends, every deployment is engineered to land in the inbox, stay there, and scale without breaking.All work is documented at handoff — every configuration file, every DNS record, every bounce rule — so your team can maintain the infrastructure independently. 30 days of post-launch support is included as standard on every engagement.

Etechinvest designs and deploys professional SMS marketing infrastructure for businesses that need reliable, compliant, and high-deliverability text message campaigns. From Twilio and Telnyx integration to self-hosted Ultimate SMS platform deployment — we build the sending infrastructure, the opt-in compliance layer, and the automation workflows that turn SMS into a high-ROI channel.Unlike generic SMS SaaS platforms, our infrastructure deployments give you full control over your sending numbers, your subscriber data, and your campaign logic. No per-message markup on top of carrier costs, no third-party platform holding your contact list, no risk of your account being suspended because another customer on the same shared platform triggered a carrier complaint.Compliance is built in from day one — not added as an afterthought. Every deployment includes TCPA opt-in flow configuration, keyword-based subscription and unsubscribe handling, and carrier-specific requirements for your number type. For US campaigns using long codes, we handle A2P 10DLC brand and campaign registration to ensure your messages are delivered rather than filtered by carriers.Campaign automation is handled via n8n — self-hosted on your server, connected to your CRM, and triggering sends based on real customer behavior rather than a fixed schedule. Delivery reporting, carrier error diagnostics, and opt-in list management are all accessible through the Ultimate SMS dashboard without requiring technical knowledge to operate day-to-day.Every deployment is documented at handoff and includes 30 days of included support from delivery day.
