Omnivery is a security-first transactional email platform for teams whose password resets, 2FA codes, receipts, and confirmations have to arrive — 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 — no third-party cloud — 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 — a combination unique among transactional providers — 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).

Possible disadvantages of iPython

  • Learning Curve
    For beginners, the extensive feature set of IPython may be overwhelming and have a steep learning curve.
  • Resource Intensive
    IPython, particularly Jupyter notebooks, can be resource-intensive, leading to slow performance on large datasets or complex computations.
  • Dependency Management
    Managing dependencies can be challenging, especially when using multiple packages in the same environment, which can lead to conflicts.
  • Limited IDE Features
    While IPython has many interactive features, it lacks some of the more advanced IDE features such as comprehensive code refactoring tools and integrated version control.
  • Exporting and Sharing
    Although you can export notebooks in various formats, sharing them in a way that preserves full interactivity can be complex compared to traditional scripts.

Questions & Answers

As answered by people managing iPython and Omnivery.

Who are some of the biggest customers of your product?

Omnivery's answer:

  • Kiwi.com
  • Notino
  • ČSOB
  • Beehiiv
  • Rouvy
  • TrueML
  • TV Nova
  • TV Markíza
  • Ohne-Makler
  • Upland (Adestra)
  • Cruxo

Why should a person choose your product over its competitors?

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 — 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.

Which are the primary technologies used for building your product?

Omnivery's answer:

Omnivery runs entirely on its own infrastructure — no third-party cloud provider — 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.

What's the story behind your product?

Omnivery's answer:

Omnivery grew out of Mailkit, an email platform founded in the Czech Republic in 2006 that became known for deliverability — "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 — loose abuse controls and weak privacy enforcement dragging down everyone's reputation and deliverability — 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.

What makes your product unique?

Omnivery's answer:

Omnivery is a transactional email platform that runs on 100% owned infrastructure — no third-party cloud — 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 — not by automated alerts.

How would you describe the primary audience of your product?

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 — 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 — with data residency available in the EU or US — 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.

    Competitors: Bird, Mailgun, Twilio
    Pros:    High email deliverability|Excellent support|Secure and easy to use|Bot detection

    Wonderful ESP with so much value

    I've been using Omnivery for a little over a year now, and the platform has continued to evolve in ways that have helped take our email program to the next level. One of the biggest differentiators is its ability to identify and report true human clicks while filtering out bot activity—something I haven't seen by other providers.

    Beyond the technology, the partnership has been outstanding. Whenever we've needed enhancements or had new ideas, the Omnivery team has been open to feedback, collaborative, and quick to work with us on solutions. Having an additional set of experienced eyes reviewing our program week after week has been incredibly valuable.

    I truly appreciate the partnership and look forward to continuing to work with Omnivery for years to come.

    Competitors: Sparkpost, netcore
