Unfortunately this is a common issue with some email providers that filter messages for security or spam purposes. It is not uncommon for 3Commas email messages to be falsely marked as spam or junk.
What can I do?
Please log-in to the webmail interface of your email provider and search for any messages from firstname.lastname@example.org
Some email providers don't send messages they may think are spam to your Smartphone or Email program, so you have to go to the webmail directly to check.
It can greatly help if you add email@example.com to your webmail address book as this sometimes "whitelists" the sending address for future messages, to ensure they are not marked as spam or filtered from your smartphone or preferred email program.
If this still does not help, please contact support and we will try to assist you!
