Email Link (Mailto Link) are links on websites that lead the user to a specified email address. The client clicks on one of the mailto links and launches the mail client on the gadget, which is specified by default, where the user can immediately send a message to the email address specified in the mailto link.
Such a system can be a good tool for marketing and communication with potential clients. Since email is the easiest way to connect, the mailto link allows you to get the most out of every customer.
However, there are also downsides to using an email link. Most spam programs collect email addresses by scanning web pages for use in their mailing lists. Also, email addresses can be collected and sold for use in databases. And even using a high-quality spam filter will not always help to get rid of such a large influx of new emails. Therefore, if you want to save user data, you should think about using the analogs of such a system.
