They Had a Product. Zero Email Marketing.

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.


Two Parallel Engines Built From Scratch

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.

1
Cold Email Infrastructure Setup
Configured DNS (SPF, DKIM, DMARC) for all sending domains. Set up dedicated mailboxes via Google Workspace. Ran full warm-up sequences before sending a single campaign email. Built the entire sending infrastructure on Mystrika.
2
ICP Research & Lead Generation
Defined the ideal customer profile — small business owners, accountants, CPAs, realtors and finance professionals who needed bookkeeping software. Scraped, verified and enriched targeted lead lists. Built segmented lists for each audience segment to enable personalized outreach.
3
Cold Email Campaign Strategy & Execution
Wrote multi-step cold email sequences targeting CPAs, realtors and real estate agents. Ran A/B tests on subject lines and copy. Managed campaigns across multiple audience segments — including NY Real Estate Agents (15,105 sent), CPA campaigns, and USBCCI Expo registrants.
4
Inbound Email Infrastructure (Fluent CRM)
Built the entire inbound email system inside Fluent CRM from zero. Created behavioral automation funnels for different user segments — new signups, dormant users who didn't connect their bank account, users who exceeded spending thresholds, and free plan users eligible for upgrade nudges.
5
Free-to-Paid Conversion Sequences
Wrote and set up behavioral drip sequences specifically designed to convert free users to paid. Built trigger-based campaigns for users who exceeded $15,000 YTD expenses, dormant users who hadn't connected their bank account, and users who hadn't selected a plan. Copy was conversational, story-driven and high-converting.
6
Seasonal & Promotional Campaigns
Created Black Friday campaigns, year-end tax strategy newsletters, and 1099 compliance guides — all timed to high-intent moments in the bookkeeping calendar. These drove some of the highest open rates across the entire engagement.

80%+ Unique Open Rates Across Multiple Campaigns

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:

99.60% Open Rate. Built From Zero.

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.

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.

Email Became Their #1 Traffic Channel & MRR Grew to $34K

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.

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.

MRR Growth Dashboard — 6 Month View
Bookkeeping SaaS MRR Growth in 6 Months

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.


What Made This Work

Building both cold and inbound email in parallel from day one meant every cold email signup immediately entered a nurture sequence — no leads were wasted at the top of the funnel.
Behavioral triggers outperform time-based blasts every time. The sequences that hit 99%+ open rates were triggered by specific user actions, not a calendar. The email arrived at exactly the right moment.
Subject lines that sound like a real person wrote them get opened. "My wife made me write this email" — 96.96% open rate. Authentic, human copy will always beat polished marketing language.
Cold email infrastructure quality directly determines open rates. The 80%+ unique open rates on cold outreach weren't luck — they came from perfect DNS setup, a proper warm-up strategy, and verified lead lists with accurate ICP targeting.
Email as a channel has a compounding effect. By month 6, email was generating 36.69% of all sessions — more than organic search and paid combined. The asset you build in month 1 keeps paying off every month.
