How we test: every rating on ToolTrusted comes from the same hands-on process — we run each email marketing tool in production, score it on a fixed five-axis rubric, and date-stamp the result. This page documents that methodology in full so you can judge our verdicts for yourself. For who we are and how the work is funded, see About ToolTrusted.
The testing protocol
Before we publish a verdict, every tool is tested in production for at least four weeks — not clicked through for an afternoon. In that window we:
- Send real campaigns to seed lists and measure inbox placement with independent deliverability testing, rather than trusting the vendor’s own numbers.
- Build at least one non-trivial automation in the tool’s workflow editor — a welcome series with branching and tagging — to test real capability, not the demo.
- Contact support at least twice, once during business hours and once off-hours (around 2 AM), and time the response on every channel the plan offers.
- Model the real price at common contact and send volumes, including what’s locked behind upgrades, so the cost reflects what you would actually pay.
- Record the platform version and the test date. Software changes; a review from 18 months ago is not a review of today’s product, so every verdict carries the date we last verified it.
Our five-axis rubric
Each tool is scored 1–5 on five axes, then averaged into the star rating you see in the verdict box:
- Deliverability — independent seed-list inbox placement, sender-reputation policy, and authentication setup quality.
- Pricing transparency — what you actually pay at common contact and send volumes, how the price scales, and what is locked behind upgrades.
- Automation depth — workflow-builder capability, trigger and condition variety, and how powerful the cheapest automation-capable tier is.
- Integration coverage — count and quality of native integrations, especially WordPress, WooCommerce, Shopify, Stripe, Zapier, and the major form builders.
- Customer support — response time, channel availability per plan, and documentation quality.
We do not weight the axes. We would rather be transparent than convenient — a tool that scores 5 on pricing and 1 on deliverability is not a 3-star tool, it is a tool with one fatal flaw, and we would rather you read that section than the headline number.
How scores become verdicts
To keep verdicts comparable across tools and over time, the averaged score maps to a fixed recommendation band:
- 4.5–5.0 — Top pick. Best-in-class for its use case; we recommend it without reservation.
- 4.0–4.4 — Strong choice. Excellent for most users, with minor trade-offs we spell out.
- 3.0–3.9 — Situational. Right for specific needs and wrong for others; read the section before buying.
- Below 3.0 — Not recommended. A material flaw outweighs the strengths for most readers.
What we publish with every review
So you can verify our work, each review states the platform version and the date we tested, a dated pricing snapshot, and the deliverability result we measured. Where we cite third-party averages — Trustpilot, G2, or Capterra — we label them as external data and keep them clearly separate from our own editorial rating. The number in our verdict box is always ToolTrusted’s independent score, never an imported one.
Independence and funding
We earn commissions from some of the tools we recommend, and every page with an affiliate link says so — see our Affiliate Disclaimer, in line with the FTC’s Endorsement Guides. What commissions never do is change a score: we do not take payment for positive reviews, let a vendor approve a draft, or rank by commission. Tools that pay us nothing have topped our rankings, and tools that pay us well have landed in our “not recommended” sections.
Updates and corrections
Tools change — pricing shifts, features ship, deliverability drifts. We re-verify our data on a regular cadence and mark each update with a revision date. If you spot something out of date, tell us via the contact page and we will re-test and correct the post.
Who runs the tests
ToolTrusted’s reviews are written by people who have built and broken email infrastructure for years. Elena Tarrant covers lifecycle and broadcast email, ESP comparisons, pricing, and automation; Raj Kapoor covers deliverability — SPF, DKIM, DMARC, BIMI, warm-up, and migrations. Our verdicts are built on that experience, not on press releases.
