What free email tools does Valid Email Checker offer?

A handful of standalone tools that work without an account. Some are companion utilities to the verification engine (DKIM/SPF/DMARC for deliverability), others are pure utilities (email signature, bulk address generation).

Free Email Verifier

Live at /tools/email-verifier. Run the same verification engine our paying customers use, on a single address, three times per day for free. Use it to spot-check a suspect address, demo the product to a colleague, or quickly clean up a tiny list. Results show the canonical status (Safe / Invalid / Disposable / Catch-All / Role Account / Spam Trap / Disabled / Inbox Full / Unknown) — no signup, no card, no friction.

DKIM record checker and generator

DKIM (DomainKeys Identified Mail) signs your outbound emails cryptographically so receiving servers can verify they came from you. The /dkim-record-checker tool reads the DKIM record published in your DNS and tells you whether it's valid. The /dkim-record-generator helps you create one if you don't have one yet.

SPF record checker and generator

SPF (Sender Policy Framework) tells receiving servers which IPs are authorized to send mail for your domain. Missing or wrong SPF records are one of the most common reasons legitimate mail lands in spam. /spf-record-checker validates your existing record; /spf-record-generator builds a new one for your domain and sending platforms.

DMARC record checker and generator

DMARC ties DKIM and SPF together and tells receiving servers what to do when a message fails authentication (none / quarantine / reject). /dmarc-record-checker reads your current policy and flags issues; /dmarc-record-generator builds a policy from scratch with a recommended starting configuration.

Email signature generator

/email-signature-generator builds professional HTML email signatures from a small form (name, title, company, photo, social links, optional banner). Export the HTML and paste it into Gmail, Outlook, Apple Mail, or any signature-supporting client. Useful for individuals and small teams that want consistent signatures without buying a separate tool.

Emails generator

/emails-generator creates realistic bulk email addresses (up to 50,000 at a time) drawn from 26 country-specific name patterns and configurable domain rules. Useful for QA test data, load testing forms, or generating placeholder content. Export to CSV, XLSX, JSON, or TXT.
