What will you get? An occasional recap email with links back to the posts of interest… and that’s it.
And what do I do with your email? Nothing, other than send out the newsletter.
Lastly, is your email safe? 100%. I own and manage the server account this site sits on. It sits in Australia’s only Tier 4 accredited data centre and no third party has access to anything around here (other than the infrastructure owners). No Mailchimp etc. Ever.
