Verifi.Email

@Verifi.Email validate the email address support@acme-corp.io and tell me if it's safe to send to

The address support@acme-corp.io is valid and deliverable. Syntax is correct, MX records exist and point to Google Workspace servers, no spoofing indicators detected, and it's not a disposable address. The domain has strong SPF and DMARC policies in place. Safe to add to your outreach list.

This example shows single-address validation, which is the most common use case for verifying a contact before sending. The MCP returns structured signals (syntax, MX, spoofing, disposable) that the AI synthesizes into a plain-English recommendation. Requires API key with validation quota; each check consumes one credit.

@Verifi.Email check the domain health for newclient.com — we're about to send a campaign and I want to know if their mail setup will cause deliverability issues

Domain newclient.com has partial email authentication: SPF is configured correctly (score 10/10), but DKIM is missing (score 0/10) and DMARC is set to 'none' policy (score 3/10). BIMI is not configured. Recommendation: emails sent to this domain should deliver, but replies from their domain may land in spam folders due to weak sender authentication. Consider advising them to harden DMARC before launch.

This example demonstrates the domain health check, which audits SPF, DKIM, DMARC, and BIMI configurations. Useful when onboarding a new client or partner to assess their email infrastructure risk. The MCP returns numeric scores and the AI translates those into actionable advice. No side effects; read-only operation.

@Verifi.Email validate this list of emails from our signup form: alice@example.com, bob@tempmail.net, carol@, dave@company.co.uk — flag any that look risky

Validated 4 addresses: alice@example.com is valid and deliverable. bob@tempmail.net is valid syntax but flagged as a disposable address (high risk for fraud or low engagement). carol@ is malformed and invalid. dave@company.co.uk is valid with strong MX records. Recommendation: accept alice and dave, reject carol outright, and consider blocking or quarantining bob due to disposable provider.

This example shows bulk validation (up to 10 addresses per request), which is ideal for cleaning form submissions or import lists in one pass. The MCP processes all inputs synchronously and returns per-address results, including malformed entries. The AI layers on risk interpretation (disposable = fraud signal). Each address consumes one validation credit.

When batch validation beats manual scrubbing for outbound teams

A 6-person sales team runs weekly cold-email campaigns and pulls leads from conference lists and LinkedIn exports. Half the bounces come from typos or dead domains, not bad targeting. The Validate Emails tool handles up to 10 addresses per call, so you can wire it into a Switchy prompt that checks each batch before import. The MX and disposable-address signals catch role accounts and burner emails that would tank your sender reputation. If your list is over 500 contacts per week, you'll hit rate limits fast and need a dedicated validation service. Below that threshold, this MCP keeps your CRM clean without a separate SaaS contract.

Why single-address validation matters for customer-facing workflows

A 3-person support team triages inbound tickets from a shared inbox and needs to flag suspicious senders before escalating to engineering. The Validate Email tool runs one address at a time and returns syntax, spoofing, and disposable flags in under two seconds. You can drop it into a Switchy agent that scans the From header and surfaces risk scores alongside the ticket summary. The spoofing check catches domain typos that slip past basic regex. If you're processing more than 50 tickets per hour, the single-address limit becomes a bottleneck and you'll want a webhook-based validator. For smaller teams doing manual triage, this MCP adds a verification layer without leaving the workspace.

When SPF and DMARC checks belong in your pre-launch checklist

A 4-person marketing team launches a new product subdomain and needs to confirm email authentication before the first campaign goes out. The Check Domain Health tool scans SPF, DKIM, DMARC, and BIMI records and returns protocol scores plus provider-specific fixes. You can wire it into a Switchy prompt that runs the audit and formats the output as a go/no-go checklist. The provider recommendations catch misconfigurations that would send your emails to spam. If you're managing more than three sending domains, you'll want a monitoring dashboard that tracks changes over time. For one-off launches or quarterly audits, this MCP gives you the technical read without a separate compliance tool.
