How this page is made
Alternatives come from Serif's own category, AI email assistants. Prices come from each vendor's pricing page and are compared at the same volume where both can be computed, and by starting price where neither can. "States that Serif doesn't" lists what we found on the other vendor's site and didn't find on Serif's, which doesn't prove Serif lacks it. How prices are read.
