Omnivery is a security-first transactional email platform for teams whose password resets, 2FA codes, receipts, and confirmations have to arrive โ in the inbox, on time. It provides both an SMTP relay and a REST API natively compatible with the SendGrid v3, Mailgun v3, and SparkPost v1 schemas, so most integrations migrate with no code changes.
Its foundations are unusual for the category. Omnivery runs on 100% owned infrastructure โ no third-party cloud โ and enforces strict sender vetting: every customer and every sending domain is reviewed before activation, there are no free plans, and the result is a clean shared-IP neighbourhood that outperforms dedicated IPs for most senders. Deliverability is handled by senior human analysts who contact you before issues become incidents, not by automated alerts.
On compliance, Omnivery is certified to ISO 27001, ISO 27701, and HIPAA โ a combination unique among transactional providers โ never stores message content, and offers data residency in the EU or US. Native security features include phishing protection, email journaling for litigation defence, and a Bot Detection API that identifies non-human interactions.
Heritage: 18+ years of deliverability expertise originating with Mailkit (2006, Czech Republic).
LaunchZone is the launchpad for new tools โ a launch platform and discovery directory where makers introduce digital products, AI tools, creative work, and SaaS platforms to the world.
Launching a product with no existing audience is the hardest part of building. We fix that by giving every maker a fair shot: submit a product in minutes, pass a quick human review, and launch into a weekly cohort where you compete for visibility against products launched the same week โ not against a years-old archive of established tools.
Discovery is organized around three worlds, each showcased the way its audience actually browses: โ Digital & AI: agents, automations, dev tools and indie apps, surfaced in trending feeds and AI category leaderboards โ Creative & Design: fonts, templates, brand kits and video, shown with rich visual gallery cards โ SaaS & B2B: subscription platforms with verified MRR badges, alternative pages, and high-intent buyer traffic
Every approved listing is permanent and includes a dofollow backlink โ real, lasting SEO value that keeps working long after launch day, alongside real first users and honest community feedback. Rankings are earned through upvotes, never bought.
Launching is always free. Optional upgrades โ a featured spot, instant listing, or a verified badge โ add extra visibility for makers who want it.
We also build free tools for makers: SEO analyzer, DR checker, OG checker, sitemap extractor, favicon generator, and more.
Whether you're shipping your first side project or your fifteenth product, LaunchZone gives you what every launch deserves: a fair start, real users, and a link that keeps working.

LaunchZoneOmnivery's answer
Omnivery is a transactional email platform that runs on 100% owned infrastructure โ no third-party cloud โ and admits only vetted senders, so every customer sends from a clean IP neighbourhood rather than a shared pool full of unknown accounts. Three things set it apart from SendGrid, Mailgun, and Amazon SES: it is certified to ISO 27001, ISO 27701, and HIPAA together (a combination no other major transactional provider holds), it never stores message content, and it includes a Bot Detection API that flags security-scanner clicks, Apple MPP opens, and botnet fraud. Deliverability is handled by senior human analysts who reach out before problems become incidents โ not by automated alerts.
LaunchZone's answer:
LaunchZone is the only launch directory where visibility resets weekly instead of accumulating forever โ new products compete fairly against peers, not a decade-old archive. Every listing also earns a permanent dofollow backlink, turning one launch into a lasting SEO asset, not just a day of traffic.
Omnivery's answer
Omnivery closes the gaps the major providers leave. Against SendGrid, Mailgun, and Amazon SES you get 100% owned infrastructure (no third-party cloud), the ISO 27001 / 27701 / HIPAA trio, native bot detection, and deliverability run by senior human analysts rather than automated alerts โ a combination none of them offer together. Migration is low-risk: the REST API is natively compatible with SendGrid v3, Mailgun v3, and SparkPost v1, so most integrations move with a credential swap, and one-click migration carries over suppression lists, bounces, and unsubscribes. Kiwi switched in 45 minutes and saw a 17% click-rate improvement. And with data residency available in both the EU and US, teams with regional compliance requirements are covered either way.
LaunchZone's answer:
Product Hunt and similar sites bury new makers under years of established launches with no fair ranking reset. LaunchZone runs a fresh weekly cohort, free human-reviewed listings, a permanent dofollow backlink for lasting SEO, and free maker tools โ real growth, not just a one-day traffic spike.
Omnivery's answer
Omnivery is built for teams that treat email as mission-critical infrastructure and can't afford a password reset, 2FA code, receipt, or booking confirmation to arrive late or land in spam. In practice that means SaaS and product teams, e-commerce and marketplaces, travel and booking platforms, and regulated industries โ financial services, insurance, and healthcare (Omnivery is HIPAA-certified, with BAAs available). It's a particularly strong fit for regulated and privacy-sensitive teams that need compliance enforced at the infrastructure level โ with data residency available in the EU or US โ and for utilities, banks, and public-sector bodies running legacy systems that can send via SMTP but can't be rebuilt around a REST API.
LaunchZone's answer:
Indie hackers, solo founders, and small teams (1โ50 people) launching digital products โ AI tools, dev apps, SaaS platforms, or creative/design work. They have little to no existing audience or marketing budget and need early users, honest feedback, and lasting SEO visibility from one fair launch.
Omnivery's answer
Omnivery grew out of Mailkit, an email platform founded in the Czech Republic in 2006 that became known for deliverability โ "the ones who know how to deliver." Over the years, customers kept asking to use that sending infrastructure directly as an SMTP and API service. Founder and CEO Jakub Olexa saw that most sending services shared the same weakness โ loose abuse controls and weak privacy enforcement dragging down everyone's reputation and deliverability โ so Omnivery was built on the opposite principle: strict sender vetting, no free plans, owned infrastructure, and compliance first. The company was founded in 2021 and the platform launched in May 2022, carrying 18+ years of deliverability heritage.
LaunchZone's answer:
We watched makers ship great products and launch into total silence โ buried under years of established listings with no fair shot. So we built LaunchZone: a weekly cohort where every launch competes on equal footing, plus a permanent SEO asset that outlasts the spike.
Omnivery's answer
LaunchZone's answer:
LaunchZone is a young platform built for early-stage makers rather than enterprise clients โ our focus is indie hackers, solo founders, and small teams launching new products, not named enterprise accounts.
Omnivery's answer
Omnivery runs entirely on its own infrastructure โ no third-party cloud provider โ built security-first with support for multiple geographic data-storage regions. Sending is delivered through a high-performance mail transfer agent exposed as both an SMTP relay and a REST API that is natively compatible with the SendGrid v3, Mailgun v3, and SparkPost v1 schemas, with real-time webhooks for delivery events. The Bot Detection API is powered by 20+ proprietary datasets built over 8+ years, combining IP reputation, user-agent analysis, behavioural pattern matching, and honeypot data.
