On autopilot.

Your ESP sends. ImpactFlow writes.
Klaviyo, Brevo and Mailchimp are excellent at sending and deliverability. None of them write emails you don’t have to rewrite.

|---|---|---|
| Email copywriting | On you | 14 emails generated after your brief |
| Consistent brand voice | Manual on every email | Brand profile remembered |
| Monthly optimization | Manual, if you remember | AI loop you trigger after import |
| Strategic diagnosis | Not included | Included from onboarding |
| Industry benchmark | Raw numbers | Compared to your sector |
| Pricing model | Priced per contact, rises as your list grows | Flat, regardless of list size |

Frequently asked questions
How long until I receive my sequences?
Instant: as soon as your brand profile is complete, AI generates your sequences. You preview, edit, and export yourself.
Does it work with my ESP?
Yes. Starter includes CSV and one-click draft push to Klaviyo, Brevo and Mailchimp. Scale adds up to 10 workspaces. Nothing is published live automatically.
What happens each month?
From month 2, import your metrics (manually or from Klaviyo), then trigger monthly optimization. You get an online before/after report in the dashboard, with a shareable client link and printable view.
Can I cancel anytime?
Yes, from your dashboard in one click, no justification, no fees. You keep access until the end of the paid period.
Can I edit generated sequences?
Yes. Export to your ESP, or pick from A/B subject and CTA variants.
Is my data secure?
Your data is hosted in Europe (AWS eu-west-1, Ireland) via Supabase. It is never shared with third parties for commercial purposes.
Does this replace Klaviyo?
No · ImpactFlow complements your ESP. Klaviyo, Brevo and Mailchimp are excellent at sending and deliverability. ImpactFlow writes and optimizes the emails. Starter includes CSV and one-click draft push. Nothing goes live automatically.
How does the Shopify integration work?
You create an access token in Shopify Admin (about 2 minutes) and paste it into ImpactFlow. We import catalogue, prices, bestsellers and segments. Copy cites real products, and product cards (image, price, link) go into the email HTML when products exist.
Do you have predictive CLV or send-time AI?
We read Klaviyo Predictive Analytics (their model, sampled profiles) into Analytics. Personalized Send Time is a Klaviyo campaign setting, not an ImpactFlow model. We do not invent CLV from a few Shopify orders.
Does the price increase with list size?
No. Starter is €79/mo (1 workspace, drafts and report). Scale is €149/mo (up to 10 workspaces). None of them scale with list size.
How should I read the numbers on this site?
The Sequence Health Scan uses your Klaviyo account and sector benchmarks. The ROI calculator is a planning tool. On the dashboard, UTM euros are Shopify orders with utm_source=impactflow · a dash means none that month.
Is deliverability a warmup?
No. We show bounce, complaints and unsubscribes from Klaviyo. We do not configure SPF or DKIM. Predictive CLV is Klaviyo’s model, imported into Analytics.
What are your technical limits?
We do not configure SPF/DKIM and we do not run an IP warmup. Predictive CLV comes from Klaviyo’s model, not ours. Revenue per flow uses Shopify orders with utm_source=impactflow · if there are none, we show a dash, not a zero. No sequence goes live automatically: drafts stay drafts until you activate them in your ESP.
