About
Email marketing should bill you for what you do, not what you keep.
day3 is a small, EU-built email tool with a single opinion: you should pay for the emails you send — never for the size of your list.
Why it exists
Most email tools punish you for growing.
Nearly every email platform charges by subscriber count. Your list grows, your bill climbs — even in the months you don't send a thing. It taxes the exact thing you're trying to do: build an audience.
day3 flips that: keep as many subscribers as you like and pay only when you hit send. One price, known upfront.
What we won't do
The short list of things day3 refuses to be.
No tax on your list
Keep 200 subscribers or 200,000 — the price is identical. Growing your audience never grows your bill.
No surprises, no upsell
No overage at month-end. No funnels, no sales call before you can send.
Your list is yours
We never sell, rent, or mine your subscribers. We process them to send your email and report on it — nothing else.
Who's behind it
A small operation, on purpose.
day3 is built by Morten Pradsgaard — the same person behind exit1.dev — under Pradsgaard Labs EMV in Copenhagen, Denmark. Deliberately small — shipped by someone who'd rather fix the product than staff a sales team.
That means you talk to the person who builds it. Email hello@day3.app and a human who can actually change the software reads it.
Built in the EU, hosted in the EU.
day3 runs entirely in the European Union, on Vercel and Supabase. Your data — and your subscribers' data — stays in the EU, encrypted in transit and at rest.
