I have an upcoming project in the pipeline that would injest emails based on a users custom email handle. The software should parse the email, strip one time password out of it, and send the data (otp and email Id and time" forward. At the same time, the user uses a browser extension to tell the server that an otp has been sent. The software should "match" the two api calls which would "give" the user the requested otp. I dunno. Should I use amazon ses+lambda+ api gateway or is there a Foss selfhosted option
