About CandorStack

CandorStack is written by Asen, a solo builder based in Sofia, Bulgaria, with a background in data science. I build and run small online businesses on the exact category of tools this site reviews: newsletter platforms, email marketing, AI voice and video, and the automation glue between them.

That's the whole premise. I'm not a reviews desk with 40 freelancers, I'm one person whose business depends on these tools working. When a platform's deliverability slips or a pricing change quietly doubles a bill, I'm the one it happens to, and that ends up in the review.

Why "candor"

Because the tool-review space mostly runs on the opposite. The standard playbook is thin summaries of vendor marketing with affiliate links attached. The bet behind this site is that plain honesty, real use, dated facts, and visible downsides, is both rarer and more useful.

What this site earns from

Some links are affiliate links: if you buy through them, the vendor pays a commission at no extra cost to you. Which relationships exist and how they're handled is spelled out in theaffiliate disclosure, and the rules that keep them from bending verdicts are in how I test.
