day3 vs. MailerLite

A MailerLite alternative that meters sends, not subscribers.

MailerLite is a well-built marketing suite for small businesses, and like most of that category it prices by how many contacts you store.

Comparison reflects each product's pricing model and scope, not specific prices, because those change, so always check the latest on MailerLite's own site.

The core difference

The bill is the difference. On a contact-metered plan a list you email once a quarter costs the same as one you email daily. day3 meters sends, so a large, quiet list is cheap and the price only moves when you actually write to people.

The same numbers, both ways

25,000 signups collected over two years, emailed twice a month when something ships.

On day3

$14/mo

50,000 sends a month fits the 50,000-email plan. 25,000 subscribers costs nothing, on this plan or any other.

On MailerLite

Depends

A per-subscriber plan bills for all 25,000 every month, including the months you ship nothing. We don't print their price here, because it changes and a stale figure would be worse than none. Check it on their own site and run these numbers through it.

Why teams move to day3

The list stops costing money

Import every address you have ever collected. Until you email them, they cost nothing.

One allowance, both jobs

Product updates and password resets come out of the same plan and go from the same authenticated domain.

Less to set up

No site builder or funnel to configure first. Verify a domain, import a list, write the update, send.

When MailerLite is the better choice

Stay with MailerLite if its breadth is the point: you want landing pages, a website builder, pop-ups and paid newsletters from one login, or a drag-and-drop designer for image-heavy campaigns. It is a capable suite for a small marketing team, and day3 is a narrow tool for a software team. Stay too if you email a small list very often, because that is the shape where a flat per-subscriber fee reads well.

Moving your list across

Five steps, in this order. The first one is the one people skip.

  1. 1

    Bring your suppression list first

    Push the addresses that bounced, complained, or asked never to be mailed again before you import a single contact. Do it in this order and day3 refuses those rows on the way in, which is the guard working rather than an error. Do it after and you have a window where a re-import can mail someone who already left.

  2. 2

    Import the contacts

    Export your MailerLite subscribers to CSV, including the custom fields you use as merge tags, and upload it. day3 dedupes, honours your suppression list and reports failed rows so you can retry just those. The API takes batches of 1,000 if you would rather script it.

  3. 3

    Carry the opt-outs across as opt-outs

    Contacts already marked unsubscribed import with that status and the date they left on, so your new tool honours a decision made in your old one. Nobody gets re-subscribed by a migration.

  4. 4

    Verify the sending domain

    Connect Cloudflare and day3 publishes DKIM, SPF and DMARC for you, then rechecks until the domain verifies. On another DNS host you get the records to paste. Authenticating the domain you already send from is what keeps your reputation intact through the move.

  5. 5

    Send one real campaign to yourself

    A test send goes to addresses you name, through the same pipeline and the same tracking as the real thing. Compare it against your old tool's output before you point the whole list at it.

What doesn't come across

Websites, landing pages, pop-up designs and paid-newsletter billing do not come across, because day3 has none of them. Drag-and-drop email designs get rebuilt in day3's composer, which is deliberately a writing tool rather than a layout canvas. Automations rebuild rather than import: day3 has triggers, waits and branches, as an early preview, without A/B splits.

Questions

Is day3 cheaper than MailerLite?
It depends on how often you send. day3 never charges for a contact, so the bigger and quieter your list, the wider the gap. A small list emailed several times a week is the case where a per-subscriber plan holds up best.
Can I import my MailerLite subscribers?
Yes, by CSV or API, with custom fields and unsubscribe status intact. Bring your suppression list first and day3 refuses those addresses on the way in rather than quietly re-subscribing anyone.
Does day3 have a drag-and-drop email builder?
No. day3's composer is a writing tool that produces clean, inbox-ready formatting. If your campaigns are laid out like a web page, MailerLite's designer is the better fit.
What about landing pages and forms?
Signup forms yes, as hosted pages, embeds or pop-ups. Landing pages and the website builder, no. day3 collects subscribers and emails them; the rest of your site stays wherever it already lives.
