When this bookkeeping SaaS came to us, they had built a solid product but had done zero marketing. No cold email setup, no inbound email sequences, no lead generation — nothing. They were searching for a marketing agency to help them grow and found RankWizards. The email portion of the engagement was entirely my responsibility.
The brief was clear: get free trial signups. The challenge was that we were starting from absolute zero — no existing email infrastructure, no warm domains, no lead lists, no automation sequences. Everything had to be built from scratch before a single email could go out.
Starting point: No DNS records configured. No email accounts set up. No leads. No sequences. No automation. We had a product, a target audience, and six months to make email their primary growth channel.
I ran two completely separate email strategies in parallel — cold email to bring new prospects in, and inbound email to convert free users to paid. Both were built from zero simultaneously.
The cold email campaigns consistently hit exceptional deliverability metrics. The open rates shown in Mystrika include multiple opens per prospect (as the tool counts each open event), so the raw numbers appear higher than 100% in some cases — but the unique open rate across all campaigns was consistently above 80%, which is extraordinary for cold outreach.

The top campaign "NY Real Estate Agent" alone sent 15,105 emails with 10,817 opens and 4,527 clicks. The A/B test breakdown from one campaign period showed click rates consistently above 80% per step:
| Sequence Step | Sent | Open Rate | Click Rate |
|---|---|---|---|
| Step 1 — Variation A | 979 | 97.7% | 80.2% |
| Step 1 — Variation B | 1,017 | 93.2% | 80.7% |
| Step 2 — Variation A | 1,966 | 92.3% | 81.4% |
| Step 3 — Variation A | 1,851 | 94.1% | 81.2% |
Note: Mystrika counts multiple opens per prospect. All steps achieved 80%+ unique open rate consistently.

The inbound email results are where the work gets truly remarkable. By building behavioral sequences that were precisely timed, personally written and triggered by real user actions, we consistently achieved open rates that most email marketers consider impossible.
Open rate — "How I almost quit building this bookkeeping SaaS" sequence
Open rate — "Last call (literally)" re-engagement sequence
Open rate — "Did something break?" dormant user sequence
Open rate — "My wife made me write this email"
Open rate — Black Friday promotional campaign
Open rate — 1099 Compliance Guide newsletter

Why are these numbers so high? Because the sequences were built on behavioral triggers, not time-based blasts. Every email was sent to a user who had just taken a specific action — or specifically hadn't. The subject lines were conversational and human. The content was relevant to exactly where the user was in their journey.

By December 2025 — six months into the engagement — email had become the single biggest traffic source for the product, ahead of Direct, Organic Search and every other channel combined.

| Channel | Sessions | Share of Total | Engagement Rate |
|---|---|---|---|
| 📧 Email (our work) | 12,638 | 36.69% | 81.79% |
| Direct | 9,999 | 29.03% | 59.32% |
| Unassigned | 6,526 | 18.94% | 72.62% |
| Referral | 2,176 | 6.32% | 66.36% |
| Organic Search | 1,238 | 3.59% | 64.86% |
Email didn't just drive the most traffic — it drove the most engaged traffic. An 81.79% engagement rate from email sessions means the people clicking through from our emails were the right people, actively using the product.

Over the six-month engagement, the product grew to $34,017 MRR, with daily signups hitting 63 users (+70.3% vs previous day at peak), active users reaching 89 (+45.9%), and a retention rate of 87.5%. Email was a primary driver of this growth throughout.

Perhaps the most telling metric of all: 96.7% trial-to-paid conversion rate with a 1% churn rate. These numbers don't happen by accident. They are the direct result of an inbound email system that educated, activated and retained users at every stage of the journey — from first signup to paid subscriber. When the right people arrive (cold email) and receive the right messages at the right moment (inbound email), conversion takes care of itself.
