Vet senders with evidence
Check signup and sending domains against their mail setup, parking status and infrastructure history. Every finding shows the record it came from.
Email intelligence · ESP partners
Know what every domain on your platform really is.
Can it take mail? Who runs its mail? Is it parked? Does it enforce DMARC? What infrastructure sits behind it? Datazag answers these for the domains your customers sign up with, send from and link to.
You get the evidence, not an approve-or-reject verdict. Keep the customer experience under your brand while Datazag supplies the email, risk and threat intelligence underneath.

Email intelligence
A domain with an MX record is not a mailbox.
- 176.2M
- domains publish a mail (MX) record
- 169.8M
- domains can actually receive mail
- 158.9M
- domains can receive mail and are not parked
We classify every domain this way, so you know which ones can really take mail. Figures as of 2026-09-27. Method and caveats →
Partner value
Protect reputation. Create new customer value.
Use Datazag to make onboarding and abuse decisions on evidence, then package the same intelligence into trust, hygiene and protection services for your customers.
Protect deliverability
Give abuse, compliance and deliverability teams external context for the domains, links and infrastructure moving through the platform.
Launch new services
Add brand protection, customer hygiene reports, link checks and deliverability intelligence as paid customer-facing offers.
Embed into your workflow
Use API, webhooks, reports, exports or cloud data shares across onboarding, pre-send checks, abuse review and analytics pipelines.
Partner service catalog
Create services around trust, abuse and deliverability.
Choose the first commercial motion: signup checks, pre-send link checks, infrastructure change alerts, customer hygiene, deliverability intelligence or brand protection.
Signup checks
Check customer domains, websites, DNS, mail setup and infrastructure history at signup and at tier upgrades.

Commercial model
Built for partner margin, not channel conflict.
The model is designed so the ESP owns the customer relationship, commercial packaging and product experience. Datazag provides the intelligence infrastructure as a predictable platform layer behind the offer.
Partner owns packaging
You decide whether the intelligence is used for internal controls, premium customer features, managed services or paid add-ons.
Datazag is the platform layer
The underlying intelligence is priced by scope: customer estate, domains, checks, data volume, delivery route, white-label needs and SLA.
Designed for service margin
Partner terms are designed to leave room for meaningful margin without publishing a fixed discount or margin percentage.
No channel conflict by design
For partner-led accounts, the customer relationship stays with the ESP. Datazag remains infrastructure behind the product experience.
Margin principle
Partner price minus Datazag platform cost equals the service margin you control.
Partner economics depend on how the capability is packaged: internal abuse controls, premium link checks, hygiene reports, brand protection, deliverability analytics or customer-facing trust services. Datazag is designed as a predictable input cost so partners can build repeatable recurring revenue around it. Specific discounts and margin targets are handled privately in the partner agreement.
Protect core sending
Reduce abuse, support load and reputation damage that can erode the value of the platform.
Attach premium features
Sell link-risk checks, customer hygiene, brand protection or deliverability intelligence to existing customers.
Reuse one intelligence layer
Apply the same data across signup checks, pre-send checks, alerts, reports and analytics.
Package trust services
Sell evidence, monitoring, hygiene, reporting and remediation rather than raw data access.
Usage rights
Built for platform services, not raw data resale.
Partners can package Datazag intelligence into their own platform controls, customer reports and managed services; Datazag data itself remains a licensed intelligence layer. Detailed terms are handled in the partner agreement.
Included
Use Datazag intelligence to power partner-led platform controls, customer reports, alerts, enrichment workflows and portal features for your own customers.
Not standalone resale
Raw data, API access, data shares or bulk exports are not for resale, sublicensing, marketplace publication or standalone redistribution by default.
Downstream partners
Services sold through your own resellers, franchisees or channel partners require written approval, pass-through terms and a separate commercial model.
Operating model
From signup and campaign activity to better decisions.
Datazag collects and explains external infrastructure signals. ESPs convert those signals into controls, analytics, customer services and recurring value.

Screen
Check customer domains, websites, DNS and infrastructure during signup, onboarding or tier upgrades.
2→
Check
Look at campaign links, landing pages, redirect chains and sending domains before or during send.
3→
Decide
Feed the evidence and reason codes into allow, warn, throttle, block or review workflows.
4→
Analyze
Enrich SMTP logs, campaign history and abuse queues with domain and infrastructure intelligence.
5
Monetise
Package the same intelligence as hygiene, protection, reporting or deliverability services.
Delivery
Use the route that fits your platform.
The same intelligence layer can support signup checks, pre-send checks, alerting, customer portals, managed reports, log enrichment and data-driven products.
API
Domain lookups for signup checks, link checks, customer portals, policy engines and review queues. Each answer comes with its evidence.
Webhooks
Push alerts and infrastructure changes into abuse, compliance, deliverability or customer-success workflows.
Reports and exports
Generate white-label hygiene reports, brand-protection evidence packs and account-review material for customers.
Cloud data shares
Use Iceberg or Delta datasets for warehouse analytics, SMTP log enrichment, customer segmentation and large-scale joins.
Managed alert feed
Receive alerts for risky domains, new certificates, infrastructure shifts and lookalike domains, each with its evidence.
Pilot path
Start with one workflow, then package the value.
A partner pilot should prove signal quality, policy fit, operational value and commercial packaging before rollout across the customer base.
Select a workflow
Choose signup risk, pre-send link checks, SMTP log enrichment, customer hygiene or brand protection as the first pilot motion.
Connect sample data
Start with a small set of customers, campaigns, links, sending domains or log samples so results are easy to validate.
Validate decisions
Review signal quality, false-positive handling, enforcement fit, analyst usefulness and customer-facing reporting value.
Package the rollout
Decide whether the production motion is internal control, premium add-on, customer report, branded service or analytics layer.
Next step
Build the ESP partner motion around your platform.
Start with one workflow, validate the intelligence, then decide whether the production motion is signup checks, pre-send link checks, change alerts, deliverability analytics or a customer-facing protection service.
