Email & SMS Retention
We build and manage email and SMS programs that lift repeat purchase rate and lifetime value - flows, campaigns, and list health aligned to the same growth plan as your ads.
✓ Flows that recover revenue on autopilot
✓ Repeat purchase rate and LTV, not just opens
✓ Email and SMS run by senior operators
How it works
Retention compounds when it's run like a system - the right flows, a real calendar, and steady testing instead of the occasional blast.
1
Audit + strategy
We review your flows, list health, and calendar to find where revenue is leaking - then map a plan tied to LTV and repeat rate.
2
Build + launch
We build the core lifecycle flows and a real campaign calendar in your email and SMS platforms, wired to clean segments.
3
Optimize + scale
We test subject lines, offers, timing, and segments regularly - and grow the owned-revenue share month over month.
What's included
Everything required to run email and SMS at a high standard - strategy, flows, campaigns, list health, and reporting tied to revenue.
1
Strategy + priorities
We align retention to your margins and goals so flows and campaigns focus on repeat revenue, not vanity opens.
2
Lifecycle flows
Welcome, abandonment, post-purchase, and winback - the automations that quietly drive 30 to 50% of email revenue.
3
Campaigns + calendar
A planned monthly calendar of email and SMS mapped to promotions, launches, and seasonality - never last-minute.
4
List health + deliverability
Segmentation, sunset flows, and hygiene so you reach the inbox and protect sender reputation as the list scales.
5
Tracking + reporting
We report owned-revenue share, repeat purchase rate, and LTV plainly - tied to blended MER, not siloed opens and clicks.
6
One plan with your ads
Retention built around the same numbers your paid team runs on, so acquisition and lifecycle pull in the same direction.
