Junk emails, also known as spam, are unwanted and unsolicited messages sent to a large number of recipients through email. These messages are often advertisements for products or services, but can also be phishing scams or attempts to spread malware.
Junk emails can clog up inboxes and be a nuisance to sort through, and it is recommended to mark them as spam and delete them.
These emails can also come through forms on your website. There are ways to protect against spam through Recaptcha and email filtering. However, spam senders are always looking for ways around these systems and it’s not guaranteed they’ll be able to block 100% of the spam emails coming through your site.
