Intro
BillionVerify has free tools for addresses, domains and messages. Here is what each one does. Start with the address. The Email Checker runs a live check on one address, and reports each flag separately. The Email Verifier asks one question. If you send to this address, will the receiving server accept it? The Email Validator is the quick screen. It checks the format and the mail servers, then stops before SMTP. Validate Email Address shows where an address breaks: at the format, the domain or the mailbox. The Disposable Email Checker tells you whether this is a temporary inbox. The catch-all check tells you whether a domain accepts mail for any address. Role Account Detection flags shared mailboxes, like info, sales or support. The Free Webmail Checker separates personal providers, like Gmail, from company domains. The Email Spam Checker looks at the domain behind an address. It doesn't read your message. The Bounce Email Checker asks the question before you send, so the bounce never happens. The Bounce Rate Calculator is for a send you've already made. Email List Cleaning handles a whole list. The free demo takes up to 20 rows, and each row keeps its reason.
Check your domain
Next, your domain. The SPF Checker reads the record your DNS actually serves. The DKIM Checker reads your public key. It needs your domain and a selector. The DMARC Checker reads your live policy and its tags. All three have a generator too, for the record you publish. The DNS Checker shows what your nameservers are serving right now. And MX Lookup shows which servers accept mail for your domain, and in what order.
Test a message
Then, the message itself. The Email Deliverability Test grades one real message across six layers. This one needs a signed-in account. The Email Header Analyzer reads the headers of mail you already received. The text stays in your browser.
More tools
And a few more tools. The Email Extractor pulls addresses out of any text, right in your browser. The phone validator checks whether a number fits its country's numbering plan. Reverse Email Lookup reports what is publicly observable about an address. It's not a people search. And the LinkedIn Carousel Downloader saves the slides from a public post.
