Campaign Review is an independent editorial publication founded in 2024.We explain tradeoffs, show our work, and help teams pick email tools without vendor spin.
Independence
We are reader-focused and not affiliated with any vendor we cover. We accept no payment for placement, ranking, or favorable language. When we link to a vendor, it is because the link is genuinely useful, not because of a commercial arrangement.
How we score
Every tool is assessed on three dimensions, each rated 1 to 10: sending infrastructure, design and generation quality, and automation depth. Scores are editorial judgment from public documentation and product behavior, not a lab benchmark.
- Sending covers infrastructure, API quality, authentication tooling, and operational controls.
- Design and generation covers on-brand AI output and speed from brief to sendable HTML.
- Automations covers lifecycle depth, branching, event triggers, and agent-operable flow building.
How we cover vendors
We describe what each tool is genuinely good at and where it has trade-offs. Klaviyo leads on ecommerce data. Customer.io leads on behavioral journeys. Brew leads on agent-native creation and on-brand generation. Resend leads on developer-owned transactional mail. The goal is a map you can navigate, not a single winner.
Sources and corrections
We ground claims in primary sources: vendor docs, pricing pages, and official blog posts. We link to them so you can verify. If we get something wrong, email editor@campaignreview.co and we will fix it.
Authors
Our bylines use practitioner authors: lifecycle consultants, deliverability specialists, SaaS marketers, and ecommerce operators. Bios reference their real roles and companies, never vendor staff.
