Free email tools

No sign-up and nothing to install. Pick the job you’re trying to do.

01

Check an email you received

Not sure a message is genuine? Check who really sent it before you click anything.

Is This Email Real? → Compare a sender with the addresses and domains the company itself publishes. Email Header Analyzer → Paste a message’s headers to trace its route and see its SPF, DKIM and DMARC results.

02

Find and organise your mail

Build searches that find the email you need — or the large ones filling your storage.

Gmail Search Builder → Search by sender, date, size, attachment or label without memorising operators. Outlook Search Builder → The same for Outlook for Windows, Outlook.com and Outlook on the web. Email Signature Generator → A clean signature to paste into Gmail or Outlook.

03

Set up an email app

Get the server details an email app asks for, and see where a domain’s mail is delivered.

Email Settings Finder → IMAP, POP3 and SMTP settings for an email address. MX Lookup → Which mail servers receive email for a domain.

04

Protect a domain you own

Stop other people sending email as your domain, and keep your own mail out of spam.

SPF, DKIM & DMARC Checker → Check all three records for a domain in one go. SPF Record Generator → Build a valid SPF record for the services that send your mail. DMARC Record Generator → Create the DMARC policy to publish in DNS. DMARC Report Analyzer → Read the DMARC reports you receive: who sends as your domain, and what fails.
