Marketo not recognizing ".us.com" email format as valid email address

[megweber221]

A user tried to register through a Marketo form for one of our upcoming webinars, but Marketo is not recognizing the email format as valid. I think it's because the email contains ".us.com." Is there a way to allow this email format?

For more context, the email is: [first initial].[last name]@[company name].us.com

@megweber221 Hi!

1. Check the "Global Form Validation Rule" in the admin settings for exclusions

2. Check the webpage code for the invalid address exclusions

If any/above is not setup and still the issue persists...please share the lading page URL for further exploration.

CSS doesn’t have anything to do with email validation.

I checked the Global Form Validation Rules in the Admin space, and we had a rule that excluded a number of email domains, including "us.com". I removed that from the rule and was able to register the user for our webinar. Thank you for your help!

You’ll need to supply your URL.

This is not standard behavior. Marketo only validates that the email address is syntactically valid (sandy@example.us.com  is valid).
