I'm looking to find out if it's possible to use custom HTML in the OTP emails sent through AWS Cognito's Passwordless sign-in feature. Specifically, can I customize the email content when I'm using SES and it's in production?

Unfortunately, you can’t customize the OTP emails yet. I actually reached out to AWS support about a month ago, and they confirmed that this feature isn't available right now.
You might want to check out AWS's documentation on customizing message settings for user pools. They have some guidance that could be helpful! Here’s the link: https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-pool-settings-message-customizations.html
Thanks for the link! But I didn't find any specific info on customizing the email OTP content. I'm really looking to adjust the email appearance.

Ohh, thanks for the update! It's good to know I’m not missing anything.
