Free email tools

Check an address, find the emails on a website, fix the records that send you to spam. No sign-up. The same engine that runs nvoke.

Start from the problem

You rarely need a tool. You need a symptom gone. Find yours.

Symptoms and the tool that fixes each
IfUse
Your emails bounce

The address may not exist anymore. Ask its mail server before you send again.

Email verifier
You guessed firstname@company.com

Guesses bounce and burn your domain. Check the guess, or find what the company really publishes.

Email verifier
You have a company, not a contact

Most companies publish an address somewhere on their site. We read the pages where it hides.

Email extractor
The contact page is a form

The imprint, privacy policy or team page often still lists an address.

Email extractor
Your mail lands in spam

Missing or weak SPF, DKIM or DMARC is the usual cause. Gmail and Yahoo require all three from bulk senders.

SPF and DMARC
You just set up a new sending domain

Check the records before the first message, not after the first hundred go to spam.

SPF and DMARC

Built on the real engine

These are not demo toys. Every check runs on the same verifier and crawler that nvoke customers use, with the same rules.

Asks, never guesses
Verdicts come from the mail server. When it will not answer, we say so.
Polite crawler
nvokebot reads robots.txt first, one page a second, at most eight pages a site.
Nothing gets sent
No test email, no tracking pixel. nvoke has no send button anywhere.

Questions

Are the tools really free?
Yes. No account, no card, no email gate. Each network gets a few checks an hour and there is a daily cap for everyone, because every check costs us real mail server and crawler time.
What is the catch?
There is none hidden. The tools are a sample of what nvoke does at scale: find companies, read their websites and check every address. If you need that for hundreds of companies, sign up.
Do the tools send any email?
No. The verifier talks to the mail server and hangs up before a message would be sent. nvoke has no send button at all.
Can I use them from a script or an agent?
Use the nvoke API instead. It does everything the app does with an API key, and agents get an MCP server. The docs are at nvoke.run/docs.

One check is a toy. A list is a pipeline.

Paste your site. nvoke finds the companies that buy from you, reads their websites, checks every address and drafts an opener for each. 50 verified emails a month, free.
