Computer Tricks and Secrets

Short answer: you can find clues about an email sender's origin in Gmail by viewing the full email headers ("Show original"), which reveal the sending servers and sometimes an originating IP address you can look up for an approximate location. It is useful for spotting scams, but it only gives a rough, often server-level location, not the sender's home address. Here is how, and what it can and cannot tell you. How to view the full headers Open the email in Gmail. Click the three-dot menu (More) at the top right of the message. Choose Show original . A new tab shows the raw email with all headers: From, Received (the server hops), SPF/DKIM results, and more. What the headers tell you Received lines: trace the path the email took through mail servers, read from bottom to top for the origin. Originating IP: sometimes present near the earliest Received line; you can look it up in an IP geolocation tool for an approximate region. SPF/DKIM/DMARC: whether...

Short answer: you can often learn who is behind an email address using legitimate methods, searching the address online, checking connected social and public profiles, and inspecting the email's details, but you cannot magically unmask an anonymous sender, and "people finder" sites that promise that are usually scams. Here is what actually works and how to handle a suspicious sender. Start with a simple search Paste the full email address into Google (in quotes). People reuse the same address across forums, social media, listings and profiles, so a search often surfaces a name, a business, or accounts linked to it. This free step identifies more senders than any paid tool. Check social and connected accounts Some platforms let you search by email to see if an account exists (though privacy settings increasingly limit this). Gravatar and similar services sometimes show a profile linked to an email. The name portion before the @ often hints at the real name. I...

Short answer: the old hack of routing Gmail alerts through Twitter SMS no longer works, but you no longer need it. Modern phones deliver instant push email, and Gmail's own priority and filter tools let you get alerted only for the messages that matter. Here is how to set up smart, instant email alerts without the noise. Why the old Twitter-SMS method died Years ago people piped Gmail into Twitter to receive free SMS alerts. Twitter ended SMS notifications and locked down its API, so that route is gone. The good news: smartphone push notifications are instant and free, making the whole workaround unnecessary. Get instant push (but only for what matters) The problem is not getting notified, it is getting notified too much. Set Gmail to alert you only for important mail: Gmail app (Android/iPhone): Settings > your account > Notifications > choose High priority only . Gmail's AI then buzzes you only for messages it judges important. Label-based alerts: create...

Short answer: to check if an email address is valid, first confirm the format is correct, then use an email verification tool to check whether the domain and mailbox actually exist, without sending anything. You can never be 100% certain an address is live without emailing it, but these steps get you close. Here is how, and how to avoid looking like a spammer. Step 1: Check the format A valid email has the shape name@domain.tld with no spaces or illegal characters. Obvious typos (missing @, "gmial.com", trailing dots) fail here. This catches simple mistakes instantly, but a well-formed address can still be fake, so keep going. Step 2: Verify the domain exists The part after the @ must be a real domain with mail servers (MX records). If the domain does not exist or has no mail server, the address cannot receive email. Email verifier tools check this automatically. Step 3: Use an email verification tool Free and freemium tools like Hunter's Email Verifier and si...

Short answer: to get a professional email like you@yourdomain.com, you need a domain name plus an email service to host mail on it. The cleanest option is a paid service like Google Workspace or Microsoft 365; the cheapest is the free email hosting many domain registrars include. Here is how to set it up and why it is worth it. Why a branded email matters An address at your own domain (you@yourbusiness.com) instantly looks more credible than yourbusiness123@gmail.com. It builds trust with customers, reinforces your brand in every email, and is more professional for a business, freelancer or portfolio. It is one of the cheapest credibility upgrades you can make. What you need A domain name (yourdomain.com), a few dollars a year from any registrar. An email service to send and receive mail at that domain. The options, compared Option Cost Best for Google Workspace Paid/user Gmail interface + business tools Microsoft 365 Paid/user Outlook + Office apps Registrar free...
