Method
How we compare. Read from their own pages, and dated.
- Rasket
- Rasket is an email API for developers: one REST API and a dashboard for transactional email and campaigns, with inbound mail, signed webhooks and an MCP server in the same product and on the same key.
- How these pages are written
- Every claim about another product is read from that company's own pricing or documentation page, and the day it was read is kept with it. Anything we could not read from a public page says Not published rather than a guess, and each page has a section naming the rows the other product wins. We build Rasket, so the pages are written by an interested party — which is why every cell is one you can check against the other company's own page.
