Affiliate Disclosure

Last updated: October 12, 2026

Newsletter Stack Guide is reader-supported. Some links on this site are affiliate links. If you click one and then buy or subscribe, we may earn a commission from the company, at no extra cost to you.

Affiliate programs we may take part in include those run by newsletter and email marketing platforms (for example beehiiv, Kit and systeme.io) and web hosting companies. If we join the Amazon Associates program, this applies too: as an Amazon Associate we earn from qualifying purchases.

What this means for you:

• We put a short disclosure at the top of every article that has affiliate links, before the first link.
• Affiliate links are marked with rel="sponsored".
• Commissions do not decide our conclusions. We point out drawbacks, and we include tools that have no affiliate program when they're the right choice.
• We only describe hands-on testing if we actually did it. Otherwise, the article is labeled "research-based".

We follow the U.S. Federal Trade Commission's guidance on endorsements (FTC Endorsement Guides).
