In terms of SMTP, some free hosting providers limit their services. In this case, you can use an external SMTP such as u003cstrongu003eGmail u003c/strongu003eor u003cstrongu003eu003ca href=u0022https://codeless.co/out/sendinblue-emailu0022u003eSendinblueu003c/au003eu003c/strongu003e. To use these services, you must create an account and obtain the SMTP server later.
