Account activation emails are sent when you sign up for a new LimaCharlie account. If you do not see the activation email in your inbox, it can typically be found in a spam / junk folder. If you're a user of Microsoft Office 365, or similar service that has server-side filtering, you may wish to check your online Quarantine (or equivalent). See the Microsoft instructions for details.
Please reach out to our support team and we can verify if a successful delivery response message was received from your mail server.
