Hi @Kal_Lam there are no issues with your email address because you only have one . in the domain. Many email addresses have two . or sometimes more.
Examples you could test with:
name@paris.msf.org
firstname.surname@redcross.org.nz
firstname.surname@kizilay.org.tr
i-surname@fcdo.gov.uk
name@savethechildren.co.uk
isurname@redcrescent.org.my
etc…
Please see the multiple prior threads linked from the above post - e.g. Request for edit to support article: Regex

Be grateful if all the forms Kobo Inc creates could have validation that allows people globally to participate. Thank you.
