Hi @osandigital,
Thank you for using Rublon.
In that case we’d like to recommend that you use the Rublon Authenticator mobile app (available for Android and iOS), which allows you to use other authentication methods like Push and TOTP.
For sending emails, we use an external service provider who has specialized in email delivery and serves some of the world’s largest organizations. As to our knowledge, there is no better solution available for email delivery. Most likely the email delivery issue needs to be resolved directly on your email server.
Kind regards,
Rublon Team
