Email marketing for Shopify stores where a mistake costs real money

A wrong email on a $30 product costs an unsubscribe. A wrong email on a $2,000 bag, a medical device, a luxury resale item or a brand with a public reputation costs a refund, a complaint, a regulator's letter or a week of damage control. EMMPA works with the second kind of store. The process is different: a review step before every send, segments instead of whole-list blasts, no discount reflex, copy written to the market's rules, and a report that shows revenue, not opens. That is where a $1,000 to $1,700 a month retainer earns its keep; below that level, a good template and a careful founder do the job.

The line we draw

In October 2026 we decided to stop selling email to small brands at a price that only works if the work is sloppy. A $30-product store with a 3,000 list does fine with Klaviyo’s templates and a founder who sends on Thursdays; an agency fee there is overhead. We now take stores where the cost of an error is high:

What changes in the process

  1. A review step before every send. Someone who did not write the email reads it: links, prices, sizes, claims, the segment, the time. On regulated products the review is against the claims list for that market.
  2. No whole-list sends. Every campaign goes to a segment: engaged 90 days by default, recent buyers suppressed, VIPs and press on their own lists with their own cadence. Whole-list sends are where deliverability dies and where the wrong person gets the wrong offer.
  3. No discount reflex. In the stores we run, the share of revenue from flows is 69% and the campaign click rate is 0.64%; stores that send a code every week sit at 0.35% within a year (see the accessories case). High-value and luxury brands cannot afford that, so the offer calendar is one offer a month at most, and often none.
  4. Flows that know the catalogue. Size, brand, material, condition, replenishment cycle. The rug store’s $7.49 per flow recipient and the resale store’s sold-out fallback are the result of building flows on the attributes the buyer actually compares.
  5. Reporting in revenue dollars. Attributed revenue, share of store revenue, flows against campaigns, popup funnel. Opens are reported as a deliverability signal only.
  6. A dedicated project manager on every account, in your time zone’s working hours, who is the single point of contact and who owns the calendar.

What it costs, and why that is the right level

Our retainers are $1,000 a month (Pro, lists of 5,000 to 30,000) and $1,700 (Elite, lists above 30,000), with a written guarantee of +25% to +30% Klaviyo revenue in 60 to 120 days or half price until we hit it. On a store doing $100K a month with email at 15%, the guarantee alone is worth $45K a year. On a store doing $20K a month, the same retainer is a bad deal, and we say so on the first call. Full prices on the pricing page.

Who we turn away

Stores under about $50K a month in revenue, stores not on Shopify and Klaviyo (or not willing to move), one-off template jobs, and any brand that wants a weekly sitewide discount as the strategy. Not because the work is beneath us; because the economics do not work for the client.
