How it works

You're billed on emails sent, not on the size of your list.

Most email marketing tools turn a growing list into a growing bill. day3 doesn't. Keep as many subscribers as you like, and pay only for the emails you send.

1

Bring your whole list

Import 200 contacts or 200,000, same price. Subscribers are free and unlimited, so a growing audience never grows your bill.

2

Send when you have something to say

Each email to each subscriber is one send. A campaign to 1,000 people uses 1,000 emails, the only number that touches your bill.

3

Watch one monthly cap

Your plan has a monthly email allotment. The meter fills as you send and pauses cleanly at the cap, with no surprise overage. Need more room? Move up a plan.

Why the two models diverge

A list and a sending schedule grow at different rates. The list compounds: every launch, every mention, every month of organic signups adds to it, and nothing takes people off it except unsubscribes. Sending stays roughly flat, because it's governed by how often you ship something worth announcing, which is a function of engineering time rather than of audience size.

Per-subscriber pricing meters the first curve. Send-based pricing meters the second. For a software team those two numbers drift apart month after month, and the gap between them is most of what you'd otherwise be paying.

There's a second effect that matters more than it sounds. When contacts cost money, every list decision is quietly a billing decision: prune the inactive, don't add the trial signups, delete the churned accounts. That's optimising your list for your invoice rather than for your business. When subscribers are free, the right list is simply the accurate one.

The arithmetic, on real numbers

Every price below is read straight off the current plan ladder, so this table can never disagree with the pricing page.

Where send-based pricing loses

Divide your monthly sends by your subscriber count. Below about one, meaning you don't email everyone every month, this model is working for you and the gap widens as the list grows. Well above one, meaning a daily or weekly letter to a modest list, a per-subscriber plan can genuinely cost less. That last row is the shape: 1,000 people emailed every day is 30,000 sends against a list most tools would charge very little to hold.

One number to watch

No contact tax, no surprise overage. The plan price is the price, and the meter shows exactly where you stand.

Common questions

How is day3's pricing different from Mailchimp or ConvertKit?
Most tools charge by subscriber count, so your bill climbs as you grow, even if you rarely email. day3 charges by emails sent. Subscribers are unlimited and free.
What counts as one send?
One email to one subscriber. A campaign to 1,000 subscribers is 1,000 sends against your monthly allotment. Transactional email through the API counts the same way, out of the same allowance.
What happens if I hit my monthly limit?
Sending pauses cleanly at the cap. No overage, no surprise charge. Move up a plan for more headroom and sending resumes immediately.
Do unused emails roll over?
No. Your allotment resets each billing period. Pick the plan that matches how often you send.
Why is this cheaper for most teams?
List size and sending frequency are different things. A founder with 50,000 subscribers who emails monthly pays far less than on a per-subscriber plan priced for that list.
When is send-based pricing the worse deal?
When you mail a small list very often. Divide your monthly sends by your subscriber count: below about one, send-based pricing is working in your favour. Well above one, meaning a daily or weekly letter to a modest list, a per-subscriber plan can cost less. We'd rather you did that arithmetic than discovered it later.
Does a test send count against my allowance?
Yes, because it's a real email through the real pipeline. Test sends only reach addresses you name, so the cost is a handful of emails rather than a campaign.
Can I change plans mid-month?
Yes, up or down, and changes apply from the next billing period. Since allowances don't roll over, the usual pattern is moving up for the month you make a big send and back down afterwards.

Stop paying for subscribers you don't email.
