Quick answer
MailerLite - MailerLite wins for most builders because its free tier is more generous for marketing use, while MailerSend is better only if you specifically need an email API or SMTP workflow.
How the free tiers compare
These products overlap on email, but they solve different jobs. MailerLite is a marketing platform: subscriber management, newsletters, automations, landing pages, websites, forms, and selling digital products or bookings. Its free tier is limited, but it gives a small builder enough of the full marketing stack to launch campaigns without stitching together extra tools. MailerSend is a sending service for developers: API, SMTP relay, templates, verification, logs, and deliverability-oriented controls. Its free tier is much smaller in sending volume and also requires a credit card, so it is less forgiving for casual use. If you want to grow an audience and run campaigns, MailerLite is the easier starting point. If you are wiring transactional or app-generated email into a product, MailerSend fits better from day one.

After you outgrow the free tier
MailerLite uses flat monthly pricing after free: Growing Business at $10/month, then Advanced at $20/month, then Enterprise with custom pricing. MailerSend also uses flat tiers for the first paid plans: Hobby at $5.60/month, Starter at $28/month, and Professional at $88/month. For small-team usage, MailerSend is cheaper at the very bottom paid tier, but MailerLite becomes the better-value marketing stack if you need campaigns, automations, pages, and a website. Costs diverge as volume and team needs rise, especially on MailerSend where higher sending and API limits map to higher tiers.

When to pick each one
Pick MailerLite when…
- You want newsletters, campaigns, or simple marketing automation in one place.
- You need landing pages or a basic website along with email capture.
- You are selling a digital product or booking and want that inside the same tool.
- You are a solo builder who wants the broadest free marketing stack before paying.
- You do not need an API-first email sending service or SMTP relay.
Pick MailerSend when…
- You are sending transactional or app-generated email from code.
- You need SMTP relay, API logs, or developer-facing email infrastructure.
- You want email verification credits as part of the same account.
- You care more about domains, templates, and delivery plumbing than campaigns.
- You are building software and need email tied to product workflows rather than marketing lists.
Bottom line
For the most common builder, MailerLite is the better free-tier pick because it covers the full marketing workflow, not just sending. You get email campaigns, automations, landing pages, a website, forms, and a small amount of selling functionality before paying. MailerSend is the better choice when the job is software email infrastructure, especially if you need API or SMTP from the start. If you are deciding where to begin with a free tier, MailerLite gives more room to build an audience first.
