Email Verifier
Validate email format with RFC-style rules, check DNS MX (and related mail-host) records, flag disposable domains and role-style addresses, surface catch-all risk and random-looking local parts, and run non-delivery mailbox checks where enabled. Free single-address verification; paid batch adds list runs with the same per-address detail on the page, filters (for example deliverable-only), and copy or download of filtered results (emails-only list, CSV, or readable report) plus a ZIP archive.
Email Deliverability Test
See how a message is likely to land before you send: paste or upload raw email source for a clear report on domain authentication signals, simple content-risk hints, and copy-friendly summaries. Subscribers can analyze larger single messages and run multi-file batches packaged as one ZIP with per-message results plus a summary file. When you explicitly use the AI Assistant option, you get optional wording suggestions aimed at clearer outreach.
Email Cleaning & Scrubbing
Paste or upload an email list (CSV or TXT) to scrub invalid addresses, flag disposable domains and role-style inboxes, and review safe, risky, and invalid rows with filter tabs. Download safe addresses as plain text for imports. Paid subscribers can scrub one or more list files in one run and download a ZIP with per-source results and stats; when you enable the AI Assistant option, each source can also include suggested duplicate clusters for likely typos or casing variants.

Comprehensive SEO analysis checking meta tags (title, description, keywords), heading hierarchy (H1-H6), keyword density, mobile responsiveness, page speed, image alt attributes, canonical tags, Open Graph tags, structured data, and actionable optimization recommendations.
Website Traffic Checker
Website Traffic Checker helps marketing and SEO teams evaluate channel performance by converting pasted traffic rows into quality and opportunity signals. You can input channel-level data including visits, unique visitors, bounce rate, average session duration, and conversion rate, then run one-click analysis to identify which traffic sources deserve immediate optimization. The tool computes weighted quality and opportunity scoring so teams can prioritize actionable channels instead of treating all traffic equally. This addresses a common analytics pain point: data exports exist, but prioritization remains unclear and slow. A sample input button accelerates onboarding and ensures formatting consistency. The optional AI Assistant is user-triggered and provides a premium channel improvement roadmap based on analyzed performance outputs, while AI processing remains securely handled on the backend.

This solves a frequent user pain point where people need quick disposable-looking email identities for short-lived workflows and data-entry testing. The output is generated instantly with deterministic input controls so teams can reproduce patterns across environments. A sample input button helps new users understand expected settings. An optional premium AI Assistant can analyze generated batch strategy and suggest alias hygiene actions such as segmentation, lifecycle cleanup, and use-case grouping. Processing is explicit, stateless, user-triggered, and built for fast repeat use.
