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: 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...
