Find out where a message really came from and whether it can be trusted: read its headers, check a domain’s SPF, DKIM and DMARC records, and open an .eml file safely. Build mailto links, and make or read .ics calendar invites.
Email Header AnalyserPaste an email's headers to see who really sent it, the servers it passed through and how long each took, and whether it passed SPF, DKIM and DMARC, with anything that looks like spoofing or phishing pointed out.
Email File ViewerOpen a saved email (.eml, or Outlook's .msg) to read it, with pictures from the web blocked so the sender can't tell you opened it, save its attachments, and check its links for text that shows one site but goes to another.
SPF, DKIM & DMARC CheckerPaste a domain's SPF, DKIM or DMARC record to have each part explained and mistakes pointed out: too many lookups, a weak ending, a missing policy, short keys. Give the domain to get the commands that look the records up.
mailto Link BuilderMake a mailto: link that opens a new email with the address, subject, body, cc and bcc filled in, correctly encoded, as a link, HTML or Markdown; or paste a link to read and change it.
Calendar InviteOpen a calendar invitation (.ics) to see when it really is, in its own time zone and yours, who’s invited and how they’ve replied, how it repeats, and anything wrong with it. Or make an .ics file for an event, and Google Calendar and Outlook links, for people to add it to their calendars.
vCard Viewer & ConverterOpen contacts saved as vCard (.vcf) files, from phones, Outlook, Google or Apple Contacts, see who's in them, and save them as one file, a file per contact, or a CSV spreadsheet. Reads vCard 2.1, 3.0 and 4.0 and writes 3.0 or 4.0, and turns a contacts CSV into vCards.
Guides
Is this email genuine?Check a suspicious email: read it safely, trace where it came from, see whether it passed SPF, DKIM and DMARC, and look at its links and attachments.
Moving contacts between contact appsMove your contacts from one app or service to another, such as Outlook, Google Contacts, Apple Contacts or a CRM: export them, merge and tidy the files, fix garbled names, and save them in the format the new app imports.
