Hi, we are developing a new webapp using NextJS and Supabase. Since yesterday afternoon, Supabase stopped sending the magic link for email sign-up/sign-in. Our code base hasn't changed in the last two days so we don't think our code is causing a problem. Here is the error message we get from Supabase server:
time="2021-09-19T14:14:00Z" level=error msg="500: Error sending magic link" component=api error="Error sending magic link email: gomail: could not send email 1: 421 Domain app.supabase.io is not allowed to send: Poor mailing list quality" method=POST path=/magiclink referer="https://www.getskylls.com/" remote_addr="67.149.210.16:60346" request_id=bcfb3554-0653-4dbc-9e84-a5d2446aae11
