Klaviyo email marketing agency for Shopify brands
1% Agency is a Klaviyo email marketing agency for Shopify brands doing $100K+ per month. We build and run your flows, campaigns, segmentation and SMS with one goal: a bigger share of revenue from channels you own. Across our clients, email and SMS bring 30% of revenue on average.
Why email matters more as you scale
Paid traffic gets more expensive as you scale, because each new customer comes from a colder audience. Email and SMS keep the blended numbers profitable. For a store doing $300K per month, the gap between a neglected program and a properly built one looks like this:
| Email program | Share of revenue | Monthly revenue from email | Contribution at 55% margin |
| Neglected | 12% | $36,000 | $19,800 |
| Average | 18% | $54,000 | $29,700 |
| Properly built | 28% | $84,000 | $46,200 |
That is $26,400 per month of extra contribution at near-zero marginal cost.
Flows we build first
| Flow | Trigger | Typical share of email revenue |
| Welcome series | New subscriber | 25-35% |
| Abandoned checkout | Reached checkout, did not pay | 20-30% |
| Abandoned cart | Added to cart, did not check out | 15-25% |
| Browse abandonment | Viewed a product, did not add it | 5-10% |
| Winback | No purchase in 60-90 days | 5-15% |
Then post-purchase, cross-sell and upsell, back-in-stock and price-drop alerts. Having flows switched on is not the same as having them work, so we A/B test each flow against real audience samples.
Campaigns, segmentation and SMS
- A campaign calendar built around your launches, promotions and seasonality
- Segments by purchase history, engagement and product interest
- SMS for launches, restocks and high-intent reminders
- Signup popups with an offer that makes subscribing worth it
We aim for a flow to campaign split between 60/40 and 70/30, with email at 25-30% of total revenue.

What share of revenue should email bring?
For a Shopify brand with a properly built program, 25-30% of total revenue. Under 15% usually means flows are missing or running on templates.
