Be aware! Always check the sender's email address
Often, the email address is not reliable. Nowadays, on the other hand, attackers also use "spoofing" to make a false email address. With email spoofing, you are sent an email from an email address that does not really belong to the sender. Check the link the button/link refers to by hovering your mouse over the link (without clicking!). You will often already see that it contains a web address, which does not correspond to the website from which the (phishing) email seems to come. The address may look like a trustworthy website, so always check that everything is spelled correctly and the address is correct.
