How to create a simple HTML form that sends email on Firebase?

[Antonio Ooi]

Hi,

I'm new to Firebase. I just posted a question on Stack Overflow yesterday but nobody seem to reply me, so I posted it here again:

I just want to know how to create a simple enquiry form that sends email to myself and the user who fills up the form upon submit button click. But I don't know which API to use as I can't seem to find any of this API in Firebase documentation (except those that managing the user email and password). I never code in PHP before except ASP.NET (but I can learn). I heard about SendGrid and Zapier but the examples given are too brief until I don't know where to start from. Furthermore, I do not want to create too many accounts just to achieve a simple thing: A HTML form that sends email!

As mentioned in my Stack Overflow post here, I do not need user authentication or database. I just want my site visitors to submit their enquiry to us. I obviously can't do this on my Google Blogger website -- that's why I need Firebase where I can embed my HTML form there.

I really need all your help here because my online form service provider is forcing me to upgrade my account with the monthly price in USD that I can't afford, so I decided to build my own simple forms using Firebase. As a beginner, I really need your help here.

Thank you very much in advance!

Antonio
