Overall AI readiness assessment

How ready mailveri.com is for AI systems

87/100

MailVeri is a legitimate email verification SaaS. Its llms.txt is accessible, well-formatted, and consistent with the homepage. No content policy violations were detected. Approved for inclusion.

Audit context

llms.txt is accessible and contains 1,674 tokens. No accessible llms-full.txt was detected, so deeper context still has to be assembled from regular pages. No separate ai.txt policy was detected; it is optional, but can clarify training, retrieval, and attribution preferences.

robots.txt is available. 11 of 11 tracked AI bots are not blocked. Declared sitemaps: 2. The homepage exposes Schema.org types Organization, WebSite, SoftwareApplication, FAQPage; 7 OpenGraph tags were found and markup completeness is 100%.

The mobile Lighthouse profile adds Performance 70/100, Accessibility 96/100, Best Practices 96/100, SEO 100/100, and experimental Agentic Browsing 100/100. These signals have a limited weight: they complement rather than replace llms.txt, robots.txt, and structured-data checks.

Agentic Browsing

What these results mean

Mobile performance is 70/100, with the largest visible content block appearing in 5.3 s and the browser main thread blocked for 20 ms. Layout shift was 0. The main thread is where the browser runs JavaScript, calculates layout, and paints the page; long work there delays both user input and browser-agent actions.

Accessibility scored 96/100, Best Practices 96/100, and technical SEO 100/100. The experimental Agentic Browsing category scored 100/100. It measures signals Google currently tests for software agents and is shown separately from the llmsmap AI-readiness score.

Free the main thread and accelerate the first view

Split long JavaScript tasks, defer non-critical scripts and styles, and shorten blocking request chains. This helps the primary content appear sooner and makes controls usable earlier.

Reduce code that loads without helping the page

Remove unused CSS and JavaScript, load heavy widgets on demand, and limit third-party scripts. Less code means less parsing and background work on the device.

Optimise images and their loading order

Serve correctly sized modern formats, prioritise the primary visual, and lazy-load content below the first viewport.

Reduce network delay

Improve server response time, remove unnecessary redirects and repeat downloads, and use compression, caching, and selective preconnect hints.

# MailVeri

> MailVeri is a high-throughput, enterprise-grade email verification SaaS platform designed for sales outreach, lead generation pipelines, marketing automation, and AI agents. It delivers 99%+ deliverability accuracy with pay-as-you-go pricing starting at $0.0002 per email (up to 90% cheaper than legacy providers), featuring credits that never expire and zero monthly subscriptions.

## Overview & Core Capabilities

MailVeri operates a dual-engine email validation architecture:
1. **Real-Time Single Verification API**: Sub-second synchronous verification specialized for point-of-capture form validation, lead scoring, CRM triggers, and AI agent tool calling.
2. **High-Throughput Bulk Verification Daemon**: Scalable async processing for massive list uploads (CSV, Excel, TXT) supporting up to 1,000,000 emails per batch with automated webhook dispatch upon completion.

### Comprehensive 9-Step Verification Suite
- **Syntax & RFC 5322 Validation**: Rejects malformed addresses, illegal recipient delimiters, and invalid characters.
- **DNS & MX Record Lookup**: Verifies destination mail exchange records with fallback cache.
- **Deep SMTP Direct Handshake**: Direct carrier handshake verifying mailbox existence without delivering actual emails.
- **Catch-All Domain Detection**: Probes domain-level wildcard acceptance to prevent deliverability traps.
- **Disposable & Temporary Domain Isolation**: Live in-memory database filtering 100,000+ burner email providers (e.g., Mailinator, TempMail, GuerrillaMail).
- **Role Account Classification**: Flags departmental/functional aliases (`admin@`, `support@`, `sales@`, `info@`, `billing@`) to reduce spam complaint risks.
- **Full Inbox Detection**: Identifies over-quota storage mailboxes that bounce incoming mail.
- **Provider-Specific Normalization**: Automatic alias deduplication and canonicalization for Gmail, Outlook, iCloud, Fastmail, and Yahoo.
- **Zero-Waste Billing Protection**: Automatic 100% credit refund on any inconclusive or temporary `UNKNOWN` verification result.
