Create and Configure SMTP and API for My Web Application

I'm looking for an expert to create and configure an SMTP and API for my web application. I need both of these services to be set up, and I'm not sure if it's necessary to enable TLS encryption yet - I'm open to advice on that.
If you have experience in configuring both the SMTP and API for a web application and know what additional features may be necessary for the security of my website, please get in touch.
