Should I Fire My Email Marketing Agency? What Changes After the Switch and What Does Not
Switching email agencies is lower friction than switching a Meta ads agency. There is no equivalent of Meta's learning phase reset: Klaviyo flows keep running through a transition, campaigns can continue on their existing schedule, and list data stays intact. The cost of switching is different and often underestimated: it is accumulated list knowledge. A good email agency over 12 months learns what subject line approaches work for this specific audience, what send times generate the best engagement on this list, which segments perform differently, and what the list's baseline behavior looks like. A new agency starts with none of that and will spend 30 to 60 days building it from scratch before they can optimize with any real confidence.
What Does an Email Agency Actually Own?
The clearest measure of whether an email engagement is working is flow revenue as a percentage of total email revenue. For a brand with an established list and core flows in place, the benchmark among email practitioners is 25 to 35 percent of total email revenue coming from automated flows. Below 15 percent on an established list means something in the flow setup or live status is not working, regardless of what the monthly report says.
Beyond flows, a functioning email agency should also be managing campaign frequency, with at minimum two sends per month to engaged segments, and improving list health over time, not letting unengaged contacts accumulate until deliverability degrades.
Fixable Problems: What Firing and Switching Can Actually Fix
Flows never properly built or left in draft
If the five core flows — welcome, abandoned cart, post-purchase, browse abandonment, and win-back — were never built or were left as drafts that went live without proper setup, a new agency can rebuild them correctly. This is the clearest case for switching: the structural work was not done and the current agency is not doing it. A new agency with a strong setup process closes this gap in the first 30 days of an engagement.
Campaign cadence too low
An email list that is not being mailed regularly enough loses engagement over time. Contacts who opted in to hear from the brand but receive one email every six weeks are more likely to mark the next email as spam or simply forget the brand entirely. A new agency with a proper campaign calendar and segmentation approach can recover engagement from a list that has been underused, though the recovery takes several months of consistent sending to established segments.
No segmentation
Sending the same email to the full list regardless of purchase history, engagement level, or product interest is one of the fastest ways to degrade deliverability and reduce revenue per email. An agency that has been doing this for months has likely accumulated a pool of unengaged contacts that is hurting open rates across the board. A new agency can clean the list and implement proper segmentation, though deliverability recovery after months of poor sending practice takes time.
Structural Problems: What Switching Will Not Fix
The list is too small to generate meaningful revenue
A list under two to three thousand engaged contacts has a structural ceiling on how much revenue flows and campaigns can generate, regardless of how well they are built. If the list has not grown because traffic to the site is low or the opt-in capture is broken, switching agencies does not fix either of those. The email channel's output is constrained by the list entering it, and the list is constrained by the traffic and capture mechanisms upstream.
The product is not suited to repeat purchase
Email's highest-leverage function in ecommerce is driving repeat purchase and reactivating lapsed customers. If the product category does not naturally lead to repeat purchase, and there is no subscription or loyalty mechanism in place, email's structural ceiling is lower than the benchmarks suggest. Switching agencies does not change the repeat-purchase economics of the product.

What to Do Next
If the flow audit shows structural gaps that have not been addressed, switching to an agency with a strong build process is the cleaner path. If flows are built but list performance is still below benchmark, the issue may be upstream of the agency entirely, and a revenue system audit identifies which layer is actually constraining email output.
