How to get free MX record

I am a student and building a website with a minimum cost. I have hosted a website on google cloud VM and brought a domain from godaddy but didn’t buy SSL as Cloudflare was providing free SST, I also didn’t buy email because it was quite costly for me. currently, I am using Gmail as my primary email id for the website, is there any way I can get a free MX record just like SSL? I just need a basic email address nothing anything fancy, so speed or performance doesn’t matter right now. slow one will also work for me.

If you are a student then please sign up for GitHub students developer pack also for free email. Wait for some day’s cloudflare email routing is in beta then you can get free email. Till then you can use improvmx.
