Confirm YOUR subscription
First, you'll want to "whitelist" or otherwise tell your email provider that messages from firstname.lastname@example.org are good for you. You'll find a message from me asking you to click a link to confirm that you want to receive content.
Also, if you use Gmail, it could end up in your Promotional tab because we send email to many subscribers at a time. Just move emails from me into your general inbox and you should be good.
