Who is InboxShuttle a good fit for?+
We partner with ecommerce brands doing $75k+ per month that want retention to become a meaningful revenue channel. If your goal is stronger repeat purchase rate, higher LTV, and more consistent email revenue, we’re likely a good fit.
How quickly will we see measurable revenue impact?+
Some improvements can appear early as flows and campaigns go live. In most cases the strongest lift happens over 60–90 days as the retention system matures and optimization compounds.
How do you measure success?+
Revenue comes first. We track flow revenue growth, campaign revenue per recipient, repeat purchase rate, LTV, and deliverability health. Open rates are directional. Revenue and retention are the real scorecard.
Why are your retainers structured this way?+
Our work focuses on building and optimizing a complete retention system, not sending isolated campaigns. Performance improves as flows, segmentation, testing, and campaign strategy work together over time.
Is there a minimum commitment?+
Yes. All engagements require a 3-month minimum. Retention systems compound over time. Most brands see the strongest results once flows, campaigns, and segmentation are running together as a cohesive system.
What makes InboxShuttle different from other email agencies?+
Many agencies focus primarily on sending campaigns. We design and optimize a full retention system across welcome, abandoned cart, post-purchase, and win-back flows, then continuously improve performance through structured testing.
Which platforms do you work with?+
We primarily work with Klaviyo, the industry standard for ecommerce email and SMS. We can also support brands using Omnisend, Drip, and other ESPs. If you’re not yet on Klaviyo, we can help with the migration.
Do you work with brands outside ecommerce?+
Our focus is ecommerce brands where retention systems have the biggest impact. Most of our clients run on Shopify and sell physical products with repeat purchase potential.
Do you replace our internal marketing team?+
No. We typically work alongside founders, growth leads, or marketing teams and take full ownership of the retention channel.
What do you need from us to get started?+
We typically need access to your ESP (such as Klaviyo), historical campaign and flow data, and basic visibility into store performance. Retention systems work best when we can analyze customer behavior, purchase patterns, and existing lifecycle performance before building improvements.
What happens after I apply?+
We review every application to make sure we can create meaningful impact for your brand. If it looks like a strong fit, we’ll invite you to a 25-minute strategy call to walk through your retention opportunities and next steps.
