Mission-critical communications infrastructure

The infrastructure you rely on when communication cannot fail.

A password reset, a fraud alert, a payment confirmation - each is a promise moving through a system. Omnivery is the transactional email infrastructure that delivers those promises with the trust, reliability, intelligence and privacy their consequence demands. Strict sender vetting protects the reputation everyone relies on - so your most important messages reach the inbox, worldwide.

White-glove deliverability

A senior analyst on your sending, from day one

Your deliverability is our product. Everywhere else, deliverability expertise is a separate invoice: a consulting tier, a premium add-on, a business unit that bills you when sending goes wrong. We do not have a deliverability business unit, because deliverability is the business.

  • Included, not invoiced. A senior deliverability analyst is part of the service from the day you onboard, on a standing call cadence. Not a support tier you upgrade into.
  • We contact you first. We monitor your sending around the clock and reach out the moment a pattern looks wrong, while it is still small and fixable.
  • Every destination counts. Not just Gmail, Outlook, Yahoo and Apple - a receiver is not less important because it is smaller.
  • A real person answers. Email or call us and you reach someone who can act. Suggest a feature or an integration and we will look at it.

Privacy & security

Privacy isn't a checkbox. It's customer experience.

We treat customer data as a responsibility, not a resource - with multiple layers of protection behind every critical message.

  • ISO certified to the strictest quality, privacy & security standards.
  • GDPR compliant - we don't just make claims, we actively built the platform for compliance.
  • We never store message content. Metadata is kept for 30 days only.
  • Strict privacy mode - fully anonymize your message metadata.
  • Phishing protection - we stop unauthorised links from being sent and alert your security team immediately.
  • Email journaling - avoid litigation by archiving a copy of every transactional message.

How our GDPR compliant email API works →

Compliance & data quality

Always current, always accurate

Up-to-date email standards are always deployed, so you're never caught unprepared by changes from Google, Yahoo and others - and the data you get back reflects reality. Regulated senders can read how this works for HIPAA compliant email and for EU transactional email.

Compliance

Configured for every receiver

Our infrastructure always sends according to the receiving side's requirements, with extensive provider relationships that reach important niche markets worldwide. Content is periodically sampled to prevent account takeovers and drive a maximum reputation score.

Inbox monitoring

Made easy

Use a single address to populate hundreds of seed addresses for effortless inbox-placement monitoring.

Data quality

The actual SMTP response

The receiving server's actual response, passed through as received. No obfuscation, no placeholder codes, no rewritten bounce reasons.

Bot detection

Half of screened clicks were bots

By June 2026, 50% of the clicks screened by our Bot Detection API were non-human, up from 34% a year earlier. Detection uses 20+ proprietary datasets so your engagement data measures people, not machines.

Bot Detection API

Identify and manage non-human interactions

Intelligence is only as good as its data. Omnivery's Bot Detection API separates humans from machines - security scanners, Apple MPP, botnets - so the decisions you and your AI make rest on signals that reflect reality. The market figures below are first-party findings from The State of Email Bots 2026, drawn from Omnivery's own sending and screening data.

  • 8+ years of industry expertise built into every classification.
  • +40% increase in active customer engagement, reported by customers using Bot Detection.
  • +10% month-on-month engagement growth for those customers.
  • ~50% of B2C email opens are non-human, a level unchanged since Apple Mail Privacy Protection landed.
  • 2% to 16% rise in the B2C bot click rate between 2023 and 2026. The click is following the open.
  • $14.4M in fraudulent ad spend saved for beehiiv over six months.
