Hi. I'm Al. I solve email problems. I know email marketing best practices, deliverability, email authentication, and how to do things with acronyms like SPF, DKIM, DMARC and BIMI. I blog about that stuff over on Spam Resource and I have written rather a large number of shell scripts (including a double opt-in mailing list signup manager.)

I live in Chicago with my wife Kate Harding.

You can email me at idontwantspam@wombatmail.com (yes, that's a valid address) but do keep in mind that I don't want to be added to your list, I don't want to publish your content on my blog, and I don't want to buy your product or service. Thanks.
