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, Founder & engineer, under Pradsgaard Labs EMV in Herning, Denmark. Same person behind exit1.dev. 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.

Why it costs what it costs

$1 a month is the real price, not a launch price.

A price this low invites a fair question: is it a loss leader that gets repriced the moment we have you? It isn't, and the arithmetic is short enough to show you.

Delivery costs us about $0.10 per 1,000 emails through AWS SES, and it's perfectly linear. There are no volume discounts upstream for us to hand down. That's why the price per thousand flattens as the plans get bigger instead of collapsing.

At the cheap end the binding cost isn't email at all. It's card fees. A $1 charge loses roughly a third of itself to payment processing before we see it, which is why nothing below $1 a month can exist and why the smallest plans sit above the trend line rather than on it.

Every tier covers its own costs as it stands. Nothing here is subsidised by a future price rise, and there's no venture money that needs a return on a schedule.

Where we are

day3 is new. Here's what that buys you, and what it costs you.

We're not going to invent a customer count or borrow someone else's logo. day3 is early, and you'd find out soon enough anyway.

What that buys you: the person who reads your email is the person who can ship the fix, usually in days. Nothing is grandfathered into a legacy plan, because there isn't one yet. And every change that lands is dated and public in the changelog, so you can judge the pace yourself rather than take our word for it.

What it costs you: no third-party reviews to read, no separate docs site yet, and a narrower product than the platform you might be leaving. If those matter more than the price and the focus, a bigger tool is the right call and we'd rather you knew now.

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.

A young product on audited, enterprise-grade infrastructure. Here's exactly how we handle security and data protection.

Trust & transparency

Everything we'd want to read before trusting a tool with a list.
