Quick answer

I'd pick MailerLite. It is cheaper in all three setups I price, on both billing bases. At 500 contacts the gap is small: Comfort is $12/month billed monthly and Campaign Monitor Lite is $13/month billed monthly. At 5,000 contacts it is wide: Comfort is $49/month billed monthly and Lite is $75/month billed monthly. MailerLite also has a permanent free plan up to 250 subscribers, and Campaign Monitor has only a trial. Campaign Monitor is the one to pick if you need more than 3 logins and don't want to move up to MailerLite's Power plan, because every Campaign Monitor plan has unlimited seats. Prices as of 1 Oct 2026.

Across the three setups below: MailerLite in 3 of 3 scenarios.

Which one fits you?

  1. Solo marketer or small business, a list just past the free tier

    MailerLite

    My pick

    $10.80/mo billed annually

    At 500 contacts MailerLite Comfort is $12/month billed monthly, or $10.80/month billed annually. Campaign Monitor Lite is $13/month billed monthly, or $11.70/month billed annually. MailerLite is cheaper on both billing bases, but only by about a dollar a month. If your list is still under 250 subscribers, MailerLite's free plan costs nothing at all.

    Why this pick, and when to skip it

    Skip it if you want several people logging in from day one without a seat cap. Campaign Monitor Lite has unlimited seats for about the same money.

  2. Growing list, sending regularly

    MailerLite

    My pick

    $44.10/mo billed annually

    At 5,000 contacts MailerLite Comfort is $49/month billed monthly, or $44.10/month billed annually. Campaign Monitor Lite is $75/month billed monthly, or $67.50/month billed annually. This is the clearest gap on the page, and it holds on both billing bases.

    Why this pick, and when to skip it

    Skip it if your team needs more than 3 logins. On MailerLite that means the Power plan, which narrows the gap.

  3. Small team managing one list together

    MailerLite logo

    MailerLite

    My pick

    $17.10/mo billed annually

    A team of three on a 1,000-contact list fits MailerLite Comfort, which includes 3 seats. It costs $19/month billed monthly, or $17.10/month billed annually. Campaign Monitor's next band above 500 contacts runs to 2,500, so the same list pays $47/month billed monthly, or $42.30/month billed annually, on Lite.

    Why this pick, and when to skip it

    Skip it if the team will grow past 3 people soon. MailerLite then needs Power, while Campaign Monitor's seats stay unlimited on Lite.

How are Campaign Monitor and MailerLite really different?

  • Free plan or trial only

    A list under 250 subscribers costs nothing on MailerLite for as long as it stays that small. On Campaign Monitor every list pays once the trial ends.

    Campaign Monitor

    No free plan. A 30-day trial, limited to 500 contacts.

    MailerLite

    A permanent free plan up to 250 subscribers, plus a 14-day trial of paid features with no card required.
  • Price once the list grows

    At 500 contacts the two are about a dollar apart. At 1,000 and 5,000 contacts MailerLite is much cheaper on both billing bases.

    Campaign Monitor

    Lite is $13/month billed monthly for up to 500 contacts, then jumps to a band that runs to 2,500 contacts.

    MailerLite

    Comfort is $12/month billed monthly at the 500-subscriber band, and it climbs in smaller steps as the list grows.
  • Seats

    A team of three fits MailerLite's cheapest paid plan. A bigger team pays for Power on MailerLite, but no extra on Campaign Monitor.

    Campaign Monitor

    Unlimited seats on every plan, Lite included.

    MailerLite

    2 seats on Free, 3 on Comfort, unlimited on Power and Enterprise.
  • Automation on the entry paid plan

    Both include automation from the cheapest paid plan, so this rarely decides the pick for a small business. MailerLite also gives you a few automations on its free plan.

    Campaign Monitor

    Automations are included on Lite and every plan above it.

    MailerLite

    3 automations on Free, 50 on Comfort, unlimited on Power.

How I calculated this

For each tool I price every current plan plus the add-ons a setup needs, from the vendor's published prices only, and take the cheapest. Monthly and annual billing are priced separately. When a limit or price isn't published, the tool shows as not fitting instead of a guess.

  • Solo marketer or small business, a list just past the free tier: A list of about 500 contacts, just past the free tiers most vendors offer. One login. Tools priced by emails sent are costed at three mailings per subscriber a month.
  • Growing list, sending regularly: A list of 5,000 contacts, sending regularly. One login. Tools priced by emails sent are costed at three mailings per subscriber a month.
  • Small team managing one list together: Three people logging in to the same 1,000-contact list. Seats, not list size, are the deciding limit. Tools priced by emails sent are costed at three mailings per subscriber a month.

Campaign Monitor vs MailerLite side by side

I compare email/CRM platforms on: Real cost per list size, both billing bases; Free-tier contact ceiling before you must pay anything; Team seats included, and the seat price past that; List segmentation depth; Automation workflow depth and any step/action limits; Deliverability and sending limits (emails per month, per day, or per rolling window); CRM and ecommerce integration depth; What happens past your plan's contact ceiling (overage pricing vs a forced upgrade).

Who should pick Campaign Monitor, and who should pick MailerLite?

Campaign Monitor

Desk research

Campaign Monitor is a contact-tiered email platform with no permanent free plan: you get a 30-day trial capped at 500 contacts, then paid plans from $13/month billed monthly for the same 500 contacts. Its strongest move is unlimited team members on every plan, with drip automations from Lite upward. Prices climb steeply with list size, and Premier gets expensive fast past 10,000 contacts.

Best for: Small teams and agencies who want unlimited seats and automations from the first paid plan, and a simple drag-and-drop email builder.

Strengths

  • A 30-day trial capped at 500 contacts lets you test the builder before paying. It is a trial only, not a free tier.
  • Unlimited team members on every plan, even Lite ($13/month billed monthly). Most competitors hide this behind a top plan.
  • Automations (drip campaigns, pre-built journeys) are included from Lite upward.

Limits

  • There is no permanent free plan. The free offer is a time-limited trial, so a list you want to keep sending to needs a paid plan from day one.
  • Pricing is contact-tiered and the steps are steep, especially on Premier. The entry rate of $13/month billed monthly on Lite covers only the first 500 contacts. Self-serve prices stop at 50,000 contacts; past that the plans switch to Contact Sales with no published price.
  • No paid subscriptions on the platform itself (unlike beehiiv or Ghost). Campaign Monitor is email-only; it doesn't process reader payments.

Skip it if you need a permanent free plan, or you need a deep multi-branch visual automation builder; Campaign Monitor's strength is drip sequences and pre-built journeys, not complex branching.

Campaign Monitor reviewCampaign Monitor pricingCampaign Monitor alternatives

MailerLite logo

MailerLite

Desk research
  • Best for solo marketers and small businesses
  • Best for growing lists sending regularly
  • Best for small teams sharing one account

MailerLite prices by subscriber count, not by locking features behind tiers, so a $12/month billed monthly plan gets the same automation builder and landing pages as the top tier, just fewer of each. The free plan is a real permanent plan, not a trial, capped at 250 subscribers.

Best for: A small business or solo marketer who wants full features at a low subscriber count and doesn't want to pay for a bigger list than they have yet.

Strengths

  • A genuine free plan at 250 subscribers, not a time-limited trial.
  • A 14-day trial of paid features with no card required.
  • Automation and landing pages scale by count, not by locking the builder away from cheaper tiers.

Limits

  • Removing the MailerLite logo needs Comfort or above.
  • API and MCP access on Free is limited and can't send.
  • Refunds are discretionary, not a guaranteed money-back window; MailerLite's terms only commit to a refund if it cancels your service on you first.

Skip it if you resell email under your own brand (MailerLite offers no white-label version), you need logo removal on the free plan, or you need unrestricted API sending without upgrading past Free.

Buying guides that rank Campaign Monitor or MailerLite

Switching between Campaign Monitor and MailerLite

Expect to export your contacts as a file, import them into the new account and rebuild your automations and templates by hand. Neither vendor publishes a migration service for this switch. MailerLite's 14-day trial needs no card and drops back to the free plan afterwards, so testing a rebuild there carries no billing risk. Campaign Monitor's 30-day trial is limited to 500 contacts, so test with a sample of your list.

What would change my pick?

  • A team that needs more than 3 logins. MailerLite then needs Power, and Campaign Monitor's unlimited seats on Lite start to count.
  • Campaign Monitor adding a permanent free plan, or a cheaper band between 500 and 2,500 contacts, would narrow MailerLite's lead at small lists.
  • A price change on either side. The scenario picks recalculate when a vendor changes a price.
