How it scored

Every dimension is scored against this discipline’s published rubric. Open one to see the claim it was scored on, what the rubric measures there and how much it weighs, and where the evidence came from.

How we scored this

We read the agency’s public record first-hand — its site, pricing, case studies and independent reviews — and score what is checkable: what is published, not how it is phrased. There is no keyword counting or sentiment scoring. The label is a judgment on those facts, which is why each dimension shows the fact that decided it, the band it was judged against, and the sources — so you can check the call, and tell us if you think it is wrong. The full method, and who pays, is on how we vet.

Lifecycle strategy and flowsExcellent

Excellent — 5 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 22% of the total score.

Benchmark — across the 22 other agencies evaluated in this discipline, this dimension runs Excellent 9 · Strong 10 · Adequate 1 · Weak 2. The typical agency here scores Strong, and none scores higher than this one.

What this dimension measures: Real lifecycle depth: segmentation, automated flows (welcome, abandoned cart/browse, post-purchase, winback, onboarding, churn), and a retention roadmap, not just batch campaigns.

Scores high — Named flow architecture and lifecycle strategy score 4-5.

Scores low — 'We'll send your newsletters' scores 1-2.

What we found — Retention-first lifecycle (browse→buy→repeat→winback) is the entire model. That is the high band above, which is why it scored Excellent.

lifecycle — lifecycle marketing: the automated email and SMS journey across a customer’s relationship — welcome, abandoned cart, post-purchase, win-back.

churn — the rate at which customers cancel.

What we found — Deliverability-conscious, engagement-driven sending. That is the high band above, which is why it scored Strong.

Verdict

Rejoiner is a retention-first ecommerce email partner, software plus an optional done-for-you managed team, operating since 2013 with $70M+ generated across 35 countries, and it carries the strongest verified review profile in the category (G2 4.8/36, Capterra 5.0/47, Clutch 5.0/14). Its whole practice is the rubric's core, converting browsers to buyers, buyers to repeat, and lapsed customers back, and one client saw email conversion rise 100%+ while email volume decreased (revenue up, sends down is precisely the 2026 signal). Pricing is fixed (platform from $25/mo, managed from $1,500/mo), which reviewers prefer over percentage-of-sales models.

The only caveat: costs stack as you add services, and there's a lot of platform feature surface to absorb. A top ecommerce lifecycle pick.
