FlowSprint
For agencies and studios
Black Friday · Nov 27 · 73 days out

You sell the Klaviyo work. We write it.

White-label BFCM email suites for agencies. 12 campaign emails, 3 flows and a send calendar, delivered in 72 hours with your name on the document and none of ours. $497 a suite.

The Q4 problem isn't demand

You already sell retention. The problem is that every client wants their Black Friday emails built inside the same six weeks, and the writing is the part that doesn't scale. You can add another Klaviyo build in an afternoon. You cannot add another copywriter in November.

So the work gets squeezed, or pushed, or quietly turned down. This exists so you don't have to do any of those.

$497 What a suite costs you. Flat, per client, no retainer and no minimum.
Yours Whatever you bill. Most agencies price a BFCM email engagement in the low thousands — that spread is yours to keep.
72h From completed intake to finished suite. Late means you pay nothing and keep the work.

How it works

  1. You send us the intake

    A ten-minute form: the client's products, exact offer mechanics, brand voice, best sellers, platform. Fill it in yourself from what you already know, or forward it to the client — whichever is less friction for you.

  2. We write the suite

    Strategy brief first, then 12 campaign emails and 3 flows — subject line, alternate subject, preview text, body copy, CTA and a design note for each, plus trigger timing and exit conditions on the flows. Then the send calendar with dates, times, segments and a suppression plan.

  3. You get it unbranded

    A clean document with your agency's name on it, or no name at all. We never appear. Tell us the brand name when you send the intake and it arrives ready to forward.

  4. You review, revise, deliver

    One revision round is included — send a consolidated set of notes within 14 days and we turn them around inside 48 hours. Your client deals with you throughout. We never contact them.

What we never do

Being straight with you

FlowSprint is new. We have no agency logos to show you and no case studies, and we'd rather say that than manufacture either.

What we have is the work. Read a complete suite — 21 emails and a full calendar, written for a store we invented so we're not publishing someone's real campaign. Judge the writing and decide from that.

The 72-hour guarantee is the other half of the answer: if we're late, you pay nothing and keep whatever we've written. The risk of trying us once is capped at your time.

Questions you're probably about to ask

Is this AI-written?

AI-drafted, strategy-led, and read end to end by a person before it leaves. The part that matters is what it refuses to do — it will not invent a number. You can see that in the sample: the highlighted fields are exactly where a generic tool would have made something up.

Can we send you several clients at once?

Yes, though slots are capped weekly so every suite stays inside 72 hours. Tell us how many you're expecting and we'll tell you honestly what we can hold.

What platforms?

Platform-agnostic copy — Klaviyo, Mailchimp, Omnisend, Attentive, Shopify Email. We write the words, flow timing and calendar. You build it in whatever they're on.

What if the copy misses the brand?

That's what the revision round is for, and voice is the thing the intake asks about most. If a revision still doesn't land, tell us and we'll sort it out rather than argue about it.

Try one.

The honest way to evaluate this is one real client suite, not a conversation. Email hello@flowsprint.net with the client's store URL and roughly what their offer looks like, and we'll send the intake form back the same day.

If it's useful, do it again in November. If it isn't, you've lost one intake form's worth of time and no money.
