The short answer

Consider four things together: were you expecting the message, does the full sender address make sense, does the link lead to the right provider, and is the requested action plausible? No single positive sign proves authenticity.

Start with the context

What does the email want you to do: pay, sign in, download a file or reply? Match it to an order or action you actually made. A familiar logo, your name and flawless writing can all appear in a fake message. A spelling error alone does not prove fraud either.

Ask four quick questions

  1. Context: can I identify the actual order, account or request?
  2. Sender: have I checked the complete address rather than just the display name?
  3. Destination: does the real link address belong to the provider?
  4. Action: am I being pressed to send money, enter passwords or codes, or install something?

If something does not add up

Stop the process. Open the provider's app, your own bookmark or a web address you already know. Look for the supposed alert there, or call a number obtained independently. If you cannot resolve the doubt, get a second opinion before acting. An automated email check can explain clues, but it cannot know which orders you made.

The key point

Context, address, destination and requested action need to make sense together.
