I'm locked out of my 6 year old Chipotle account because they now say my email address is invalid when I login. Here is me asking for their help:

I also reached out to them on Twitter but they directed me to this form. I followed up with them on Twitter with what happened in this screenshot but they are now ignoring me.

The best of validation is just to confirm that the email contains a
@
and a.
and if it does send it an email with a confirmation link.TLDs are valid in emails, as are IP V6 addresses, so checking for a
.
is technically not correct. For examplea@b
anda@[IPv6:2001:db8::1]
are both valid email addresses.I feel like using
a@[IPv6:2001:db8::1]
is asking for trouble everywhere online.But its tempting to try out, not many people would expect this.
try user@123.45.67.89.in-addr.arpa or user@d.e.a.d.b.e.e.f.0.1.2.3.4.5.6.7.8.9.a.b.c.d.e.f.0.0.0.0.1.2.3.4.ip6.arpa just for the giggles. Mix it with BANG-Adressing:
123.45.67.89.in-addr.arpa!d.e.a.d.b.e.e.f.0.1.2.3.4.5.6.7.8.9.a.b.c.d.e.f.0.0.0.0.1.2.3.4.ip6.arpa!user
Jeez and I feel like I'm tempting fate just by using a custom domain.
