Email & lifecycle agency stop renting every customer from paid.
Most brands overpay for new customers and underwork the ones they have. We build email and SMS as a retention system: core flows first, campaigns only when they have a job, measured on revenue and list health — not open-rate theater.
Higher LTV. Recovered revenue. Cleaner list health.

Direct answer
What is lifecycle marketing?
An email and lifecycle agency builds the journeys that convert trials, recover carts, and keep LTV moving. I built this desk because I kept watching brands treat the inbox like a free media channel — then wonder why paid had to refill the bucket every month. Most teams run a sending tool: a campaign calendar, an open-rate slide, a welcome series that still says 'Hi {{first_name}}.' That is not retention.
Klaviyo's own benchmark data is blunt: automated flows generate about 41% of email revenue from roughly 5% of sends, with revenue per recipient many times a campaign. Healthy programs sit in a 40–60% flow-revenue range. If you are under 30%, you do not have a lifecycle engine. You have a newsletter. SpikeROAS maps the moments, builds the core flows, then treats subject, offer, and timing like media — with a kill rule.
SMS is a scalpel when the list and the law allow — GDPR, consent, quiet hours, and whatever your market actually requires. It is not a second inbox for junk. We implement on Klaviyo, HubSpot, or Salesforce. We do not rent lists. We do not torch a domain for a one-week spike. Lifecycle stays on the same P&L as paid so email cannot steal credit with a last-click miracle.

Fit
Who this lifecycle agency is for
Ecommerce, SaaS, and sales-led teams with a list, a CRM, or a leaky post-click journey — in any market whose consent rules we can honor.
Ecommerce & DTC
Welcome, abandon, browse, post-purchase, replenish, win-back. SMS as a scalpel when consent is real. The job is repeat purchase and contribution — not a prettier campaign theme.
SaaS and trials
Activation, expansion, and failed-payment sequences. Not a weekly product dump. If the trial does not activate, more ads will not save the unit.
Lead-gen nurture
SQL-aware drips that respect people who are not ready — and stop nagging the ones who never will be. Paid should not be the only way a good name comes back.
Who we will not take
- Blast-only programs with no flows and no list hygiene.
- Bought lists. We will not torch your domain for a one-week spike.
- Teams that want daily SMS without a consent architecture that would survive an audit.
- Shops that want email to 'prove' paid is unnecessary via last-click. We will not run that movie.
The leak
Why the inbox underperforms
Campaigns without flows
A pretty newsletter and an empty welcome series. Flows fire on intent. Campaigns fire on a calendar. If flow revenue is thin, you are running a sending tool, not a system.
Spam as a growth hack
Deliverability dies, then paid has to refill a poisoned list. Authentication, sunsets, and consent are P&L issues — not IT chores.
Attribution fights
Email takes credit for branded search and yesterday's ad. We will not let lifecycle steal blindly. Flow and campaign revenue are reported honestly, next to paid.
One message for everyone
VIP and unengaged get the same send. That is how you train people to unsubscribe — and how you teach the mailbox providers you are noisy.
On the desk
Email and lifecycle services on the desk
Blueprint, core flows, tests, hygiene. Then campaigns that have a job. We do not sell unlimited sends.
Lifecycle map
Welcome, nurture, abandon, win-back, VIP. Where a human should hear from you — and where they should not. The map is the product. The calendar is a consequence.
Platform build
Klaviyo, HubSpot, or Salesforce journeys. We implement on your stack, not a mystery ESP. The objects and events have to be true or the flows will lie.
Offer and creative tests
Subject, offer, timing — with a kill rule, like ads. Welcome and abandon get tested first. Vanity A/B on a blast is not a program.
SMS
A scalpel when the list and the law allow. Combined email-plus-SMS flows often earn more per subscriber. Combined spam is still spam.
Deliverability and hygiene
Authenticate. Sunset unengaged. Stop lighting the domain on fire. A poisoned list makes every other channel more expensive.
Revenue dashboard
Flow revenue, campaign revenue, and a grown-up view versus paid. Open rate is a distorted metric. Click, revenue per recipient, and list health are the desk.

Map the moments
Audit flows, list health, consent, and the sends that should never have gone out. You get a kill list before we write another campaign.

Build the core
Welcome, abandon, nurture. The 80/20. Then browse, post-purchase, or win-back once the spine is live.
Days 51–90
Optimize like media
Tests with a kill rule. Sunset policy live. Campaigns only if they have a job. Flow vs campaign revenue on one scoreboard.

Protect LTV
Lifecycle stays on the desk so paid is not the only way you grow. Replenish, VIP, and expansion come after the core is earning.
The fork
SpikeROAS vs a blast shop vs in-house
Flows and hygiene beat another newsletter theme. Hire us when you need a retention system on the same P&L as paid. Stay in-house when the core flows are already earning and deliverability is clean.
| Factor | SpikeROAS | Typical agency | In-house |
|---|---|---|---|
| Priority | Core flows before campaigns | Monthly campaign calendar | Whoever has Canva |
| Discipline | Kill rules, sunsets, consent | Send more | Fear of unsubscribes, so they send anyway |
| Attribution | Does not steal credit from paid | Last-click email miracle | ESP default |
| SMS | Scalpel, consent-gated | Second blast channel | Often ungoverned |
| Markets | One system. Local consent, language, and quiet hours. | One sequence, mailed everywhere | Strong at home; risky abroad |
Pricing philosophy
No fake menu. An honest gate.
Lifecycle is scoped on flows, ESP complexity, and list size — not 'unlimited campaigns.' If the money is in automations, that is what we price. On the call we will tell you flows-first or 'your deliverability is the fire.'
- Klaviyo vs HubSpot vs Salesforce changes the build. We will not pretend they are the same.
- SMS is optional and gated by consent in your market. We will not bolt it on to chase a fad.
- We do not rent lists. Bought names are how domains die.
- Best paired with CRO and paid so the click, the page, and the inbox tell the same story.
The call
What happens in 30 minutes
- 30 minutes. Working session, not an ESP tour.
- Which platform, roughly how big the list is, whether core flows exist, and whether you have a deliverability problem you can feel.
- We will tell you flows-first, hygiene-first, or stay in-house.

FAQ
Questions we get about Email & Lifecycle
What is lifecycle marketing?
Lifecycle marketing is the system of automated and campaign messages — email, SMS, in-app — that move a person from first touch to repeat revenue. It includes welcome, abandon, nurture, win-back, and VIP. We measure revenue and list health. Open-rate theater is not the product.
Should we prioritize email flows or campaigns?
Flows first. Klaviyo benchmark data shows automations can drive about 41% of email revenue from a small slice of sends. Healthy programs often sit at 40–60% flow revenue. Campaigns still matter for launches and commercial moments. They do not replace a missing welcome or abandon series.
Email or SMS?
Both when the list and the law allow. SMS is a scalpel; email is the spine. Combined flows can earn more per subscriber. We will not bolt SMS onto a messy list, or ignore quiet hours and consent, to chase a channel fad.
Do you blast newsletters?
Campaigns yes, vanity blasts no. If a send does not have a job — a segment, an offer, a reason — it does not send. Flows come first. A prettier campaign theme is not a lifecycle program.
Which platforms do you build on?
Klaviyo, HubSpot, and Salesforce journeys. We implement on your stack. We are not migrating you to a pet ESP for our convenience. If your objects and events are a mess, we say so before we write pretty emails on top of a lie.
How do you handle deliverability?
Authentication, list hygiene, and sunset policies. Sending more to a poisoned list is how you fund paid forever. If the domain is already on fire, that is week-one work — not a footnote after the campaign calendar.
Will email steal credit from ads?
It can, if you let last-click lie. We report flow and campaign revenue honestly and keep paid in the conversation so you do not pause media because an email opened. Lifecycle protects CAC. It does not pretend paid is optional.
How fast does lifecycle pay back?
Core flows can recover revenue in weeks on ecommerce — abandon and welcome especially. Nurture for long B2B cycles is slower and still worth doing. We will not quote a fake 2–4x ROI as a guarantee. That range is typical when the stack was empty, not a promise.
Do you work with lists worldwide?
Yes — when consent, language, and sending infrastructure can honor the market. GDPR, local spam rules, and quiet hours are not optional. We will not run one English blast to every country and call it lifecycle.
Do you buy or rent lists?
No. Bought names are how domains die and how paid has to refill the bucket. If someone sold you a list, the first job is usually to stop the bleeding, not to send a welcome discount.
