How does IRBIS help with email verification?

IRBIS goes beyond standard email syntax and deliverability checks. It searches the email against 200+ platforms and social networks to determine if a real person is behind it. An email that's syntactically valid but has zero linked accounts is a much weaker lead than one with an active digital presence.

What's the integration approach?

Standard REST API. POST an email or phone to the enrichment endpoint and GET results using the lookupId. Most teams integrate at the point of form submission, CRM contact creation, or lead import. Full documentation at api-docs.espysys.com. Free trial credits on registration.

Lead Enrichment API · Identity Intelligence

Your Leads Are Only as Good
as the Data Behind Them

Q: Can IRBIS detect fake or bot-submitted leads?

Yes. Fake leads typically have thin or non-existent digital footprints — a disposable email with no linked accounts, a VoIP phone number, or a name with no social presence. IRBIS surfaces these signals at the point of form submission or CRM ingestion so low-quality leads never reach your sales team.

Q: Where does IRBIS fit in a lead generation stack?

IRBIS sits between lead capture and lead scoring. You call the enrichment API with an email or phone number right after a form submission or CRM ingestion. IRBIS returns identity signals — social footprint, carrier data, breach status — which your scoring model uses to qualify the lead.

Q: Does it work for B2C as well as B2B leads?

Yes. B2B enrichment tools like Clearbit and Apollo focus on professional identity — company, role, LinkedIn. IRBIS enriches personal digital identity — social accounts, phone intelligence, digital footprint. This makes IRBIS particularly strong for B2C platforms and any use case where the lead is an individual rather than a company contact.

IRBIS enriches emails and phone numbers with social footprint, digital identity signals, and breach data — so your platform delivers qualified leads, not just contact records.

The problem

A Contact Is Not a Lead

An email address and a phone number tell you almost nothing about the person behind them. That's the gap between what lead gen tools collect and what sales teams actually need.

🤖

Fake and bot-submitted leads

Disposable email addresses, VoIP numbers, and bot-generated form submissions look identical to real leads in your CRM. By the time sales calls it a dead end, budget has already been wasted routing it through the pipeline.

👻

Thin identities with no digital history

The email is real. The phone is real. But the person has no LinkedIn, no social presence, no digital footprint at all. These leads look valid on paper but rarely convert — and enrichment before scoring would have filtered them.

🧩

You have the email. You don't know the person.

Your CRM has 50,000 contacts. Each one is just an email and maybe a name. The ones with rich digital identities — active social presence, real phone, established accounts — convert at 3x the rate. You just can't tell them apart yet.

Enrichment signals

What IRBIS Adds to Each Contact

Four enrichment types — each one turning a bare contact record into a qualified identity signal your scoring model can actually use.

✉️

Email → Digital Identity

id: "email"

Search an email address across 200+ platforms and social networks. How many accounts are linked to it? What platforms? How old is the digital footprint? An email tied to a LinkedIn, Twitter, and GitHub account is a fundamentally different lead than one with no linked presence.

Social profilesPlatform countFootprint ageThin = low quality

📱

Phone → Real Person Signal

id: "phone" · "real_phone"

Is the number real and active? Is it mobile, VoIP, or landline? What carrier? Is it registered in WhatsApp or Telegram? A mobile number on a major carrier with messaging app presence is a strong signal of a real, reachable person. A TextNow VoIP number is not.

CarrierMobile / VoIPMessaging appsVoIP = flag

👤

Name → Social Graph

id: "name"

Search by full name across social networks and the open web. Returns matched profiles, linked usernames, and presence consistency. Useful for enriching leads where you have a name but no email yet, or cross-validating that the name matches the email and phone on file.

Social accountsUsernamesPresence score

🔓

Breach Exposure Check

id: "breach"

Has this email or phone appeared in known data breach databases? Breach exposure is a reliable signal for disposable or recycled contact data — addresses that have been used in bulk signups, bot campaigns, or scraped from leaked lists rather than entered by a real person.

Bot / scraped signalBreach countExposure dates

Combine signals for a quality score: A lead with a mobile carrier, 12 linked social accounts, zero breach exposure, and a 5-year email footprint scores very differently from one with a VoIP number, no social presence, and three breach appearances. IRBIS gives you the raw signals — your model builds the score.

How it works

Where IRBIS Fits in Your Stack

IRBIS is identity intelligence infrastructure — it sits between lead capture and lead scoring, giving your model the signals it needs to make better decisions.

Contact submits email, phone, or name

Form submission, CRM ingestion, CSV import, or real-time API call from your product

Your scoring model uses enriched data

Lead quality score, segment assignment, routing logic — IRBIS gives your model better inputs

Route / score / discard

Good contacts reach sales fast. Thin or suspicious ones get filtered. No more junk in the pipeline.

What platforms stop dealing with after adding IRBIS

→ Bot-submitted form entries clogging the CRM

→ Sales reps calling VoIP numbers that go nowhere

→ Disposable emails burning outreach sender reputation

→ Lead scores that treat all contacts identically

→ Paying for 4 separate enrichment providers to cover email, phone, social, and breach

Most teams start with the email endpoint — it catches the majority of thin and fake leads immediately. Phone and breach checks layer on for higher confidence scoring.

How we compare

IRBIS vs Other Enrichment APIs

Most enrichment tools cover firmographic or B2B data well. IRBIS covers personal digital identity — the layer they all skip.

IRBIS and Clearbit/Apollo are complementary, not competing. Clearbit enriches the company layer — IRBIS enriches the person layer. Many teams use both.

FAQ

Enrichment API — FAQs

How does IRBIS improve lead quality?

IRBIS enriches submitted emails and phone numbers with real identity signals — linked social accounts, digital footprint depth, carrier data, and breach exposure. Leads with thin digital footprints, VoIP numbers, or no social presence are flagged before they enter your pipeline or CRM.

What signals does IRBIS add to a lead record?

From an email: linked social profiles, platform accounts, footprint age, and breach history. From a phone number: carrier, line type (mobile vs VoIP), owner name, and messaging app presence. From a name: social graph across 500+ platforms, linked accounts, and presence consistency score.

Can IRBIS detect fake or bot-submitted leads?

Yes. Fake leads typically have no digital footprint — a disposable email with no linked accounts, a VoIP phone, or a name with no social presence. IRBIS surfaces these signals at form submission or CRM ingestion so low-quality leads never reach your sales team.

Where does IRBIS fit in a lead generation stack?

Between lead capture and lead scoring. POST an email or phone to IRBIS right after form submission or CRM ingestion. IRBIS returns identity signals which your scoring model uses to qualify the lead. It's one extra step that changes what your entire pipeline works with.

Is IRBIS a replacement for Clearbit or Apollo?

No — IRBIS is identity intelligence infrastructure. Clearbit and Apollo cover the B2B firmographic layer — company, job title, revenue. IRBIS covers the personal identity layer — social footprint, phone intelligence, breach data. They're complementary and many teams use both.

How does it help with email verification?

IRBIS goes beyond syntax and deliverability checks. It searches the email across 200+ platforms to determine if a real person is behind it. An email with zero linked accounts is a much weaker lead than one with an active digital presence — regardless of whether it delivers.

Does it work for B2C leads as well as B2B?

Yes — and this is where IRBIS is strongest. B2B tools like Clearbit focus on professional identity (company, LinkedIn). IRBIS enriches personal digital identity — social accounts, phone intelligence, digital footprint. It's particularly strong for B2C platforms and consumer-facing products.
