The short version
- The first two weeks are audit and foundations, not sending.
- Most brands see improvement inside 30 days, usually from a broken or missing flow.
- By day 60 to 90 the compounding starts to show in attribution.
- Approvals, brand direction and creative assets stay on your side.
Most agency pages tell you what they deliver without telling you when anything happens or what is expected from you. This is the version we would want to read.
Here is roughly how the first 90 days go, what moves and when, and the parts that stay your responsibility no matter who you hire.
Before anything: the audit
Nothing should get built before someone has looked at the account properly. That means how your store data is syncing, which events are actually arriving, how the list has been segmented historically, what the flow layer covers, and what your sending reputation looks like.
Those four things set the ceiling on everything that follows and they are almost never audited. A large share of accounts we look at are missing key events or never had the tracking enabled that makes browse abandonment possible, which quietly caps what any automation can do.
The audit should also produce an honest answer about whether the engagement is worth doing at all. If you already have a strong in house team, the right answer is sometimes no.
Month one: foundations and the fastest wins
The first weeks go on account structure, engagement based segmentation, deliverability, and fixing or building the flows that carry the most revenue. Welcome, abandoned checkout and post purchase come first because that is where the money is.
This is usually where the first improvement shows, and it is often unglamorous. A broken conditional split, an abandoned checkout sequence that was one email long, or browse abandonment that was never switched on. Most brands see something move inside 30 days for exactly this reason.
A campaign calendar starts running in parallel, segmented from the beginning rather than sent to everybody.
Month two: depth and testing
With the foundations in place, the work moves to branching the flows properly, cart value, category, purchase number, and building out the remaining sequences: browse abandonment, win back, VIP and replenishment if you sell consumables.
Testing becomes routine here rather than occasional. At least two meaningful tests a week on lifecycle performance, run inside the flows as well as on campaigns.
This is the month where the account starts to feel like a system rather than a list of tasks.
Month three: compounding
By day 60 to 90 the effect starts showing in attribution rather than in individual sends. On one account, attributed revenue moved from $383,309 to $822,942 a month, and email went from 25.16% to 39.07% of total revenue. On another it went from $168,892 to $319,437 a month.
Your results depend on where you started, your list size and how often your customers buy. A store with a large neglected list moves faster than a small one with an already tidy account. The audit should give you a realistic version of this rather than a brochure version.
What stays your job
Brand direction and approvals. You know your customers and your margins better than any agency will in the first quarter, and the fastest programmes are the ones where the client answers questions quickly.
Creative assets. Photography and brand materials come from your side, in house or through a freelancer.
Being reachable at the start. Most of the input needed from you is front loaded into the first couple of weeks to get up to speed on the brand. After that it is approvals and a regular check in.
How to judge whether it is working
Ask for attributed revenue as a share of total store revenue, and watch it monthly. Ask for the flow versus campaign split. Ask what was tested last month and what the test showed.
If the reporting leads with open rate, push back. It is the easiest number to move and the least connected to your bank account.
