SaaS email marketing agency for founders who own retention.

B2B SaaS at Series A and Series B is the core. Vertical SaaS (industry-specific platforms), horizontal SaaS (broad-market tools), and product-led growth SaaS where lifecycle is the primary expansion lever. We do not work with pre-product startups, pre-activation companies whose users have nowhere meaningful to land, or companies whose unit economics will not survive the engagement cost. We tell you no when it does not fit, and we tell you on the diagnostic call, not three months in.

SaaS marketing is the full stack: acquisition, activation, retention, expansion, brand. SaaS email marketing is the lifecycle layer specifically: onboarding, expansion, retention, and win-back flows tied to product events. We run it inside the broader engagement when the brand needs the retention curve fixed before scaling acquisition. Email alone will not save a brand with bad product-market fit, but proper lifecycle is the cheapest lever for net revenue retention at every stage from Series A onward.

Deliverability is treated as discipline, not a setup task. Domain warmup before any new sending pattern. SPF, DKIM, and DMARC properly configured. Transactional emails on a separate IP pool from marketing emails. List hygiene and engagement-based pruning every quarter. We audit inbox placement quarterly with seed lists across Gmail, Outlook, and Yahoo. Sender reputation problems are the single fastest way to break a lifecycle program, and most agencies do not look at them until something visibly breaks in the dashboard.

Onboarding rebuilds produce visible activation lifts inside 30 to 60 days of going live. Net revenue retention shifts take 90 to 180 days because the cohort math needs at least one full retention cycle to play out before the new behavior shows up in the numbers. Expansion ARR programs show in 60 to 120 days. We set the lag expectations with the board at kickoff so the team is not chasing weekly noise in numbers that move on quarterly arcs.

We work with whatever your stack is. Most B2B SaaS engagements run on Customer.io, Iterable, Braze, or HubSpot. We do not switch ESPs unless your current platform is structurally blocking the work, in which case we say so on the diagnostic call and scope the migration separately. The first thirty days are mapping your existing flows to the new architecture, not pitching software. The platform is a tool, not the engagement.

Yes. The 950M lifetime view count aggregates the operator's work across the last decade across B2B and B2C. The 35 percent average CAC reduction is across portfolio engagements. Mailly is our own B2B SaaS, named in our public proof points file. Every named-account SaaS email marketing engagement number is shared under NDA on the diagnostic call. The internal voice audit rejects fabricated stats automatically, so you will not see unsourced retention claims anywhere on this page.

Horizontal SaaS where product activation is well-defined and the user is the buyer (productivity, developer tools, marketing tech). Vertical SaaS at Series A and Series B where lifecycle is the primary expansion path. Product-led growth SaaS broadly. We are less specialized in enterprise-only SaaS with twelve-month sales cycles where email is not the primary retention lever, and we will say so on the call if your model is closer to that shape so you can hire a partner with deeper enterprise email experience.

If you have a working in-house lifecycle team and need senior staff augmentation, hire a fractional executive. If your churn problem is fundamentally a product problem (broken activation, missing value moment, unclear pricing tier mismatch), fix that first because no email sequence will save it. If your runway is under six months, fundraise first. We have turned SaaS founders down for all three reasons in the last year, and we will tell you no on the diagnostic call if any of these apply.
