MailerSend pricing: plan fees, limits and yearly billing

MailerSend’s public tiers are Free at $0 for 500 emails per month, Hobby at $6.30, Starter at $31.50, and Professional at $99. Hobby includes 5,000 messages, while Starter and Professional list 50,000. Hobby is shown as $75.60 billed yearly, Starter as $378, and Professional as $1,188. I checked the MailerSend pricing page on October 7, 2026.

Scenario arithmetic

At 400 messages, Free is $0, and 500 is the monthly ceiling. At 5,000, Hobby is $6.30 per month; its yearly display totals $75.60, which is 12 × $6.30. At 10,000, the available included volume depends on moving beyond Hobby, so compare the next tier instead of assuming Hobby overage.

At 50,000, Starter is $31.50 per month, or $378 across twelve monthly equivalents. Professional is $99 for the same listed email volume, or $1,188 yearly. The difference is $67.50 per month, which buys unlimited users and domains plus 150 SMS according to MailerSend's pricing page. If your only need is email API throughput, Starter is the lower-cost fit; if agency access and many domains matter, Professional’s extra controls may justify the premium.

MailerSend also advertises a 14-day trial with Professional features, limited to 500 emails per month. Treat that as a trial window, not as a second production allowance.

Free plan reality

Free is sized for occasional testing. The 500-message cap and 100 daily API-request limit are separate constraints; a low message count can still collide with request volume if your code retries or renders many templates. One domain and one user also make it a poor fit for a multi-environment team.

Why annual billing matters

The page presents annual totals alongside monthly equivalents. Record both when comparing vendors: Hobby’s $6.30 monthly equivalent becomes $75.60 billed yearly, Starter’s $31.50 becomes $378, and Professional’s $99 becomes $1,188. Cash timing and cancellation terms belong in procurement review; the headline monthly figure alone does not tell that story.

Plan-specific gotchas

Starter and Professional both list 50,000 email, so the decision is about account shape rather than just volume. Starter has five seats and ten domains. Professional removes those ceilings and includes 150 SMS, which can matter for an agency or a product with multiple brands. Do not pay for Professional merely because the word “scale” appears; count users, domains, and SMS needs.

Who should choose MailerSend?

Choose Free for a small integration test. Choose Hobby for a side project near 5,000 monthly messages. Choose Starter for a growing product that fits 50,000 messages and a five-seat team. Choose Professional when unlimited access, many domains, or included SMS is part of the operating requirement.

For an alternative with a larger free message allowance, compare Resend. For dedicated transactional streams, see Postmark. For a managed SMTP-first path, read SMTP2GO.

Migration notes

Export templates and variables, sender domains, suppression lists, API keys, and webhook mappings. Recreate each domain in a non-production workspace, authenticate it, and send a small password-reset cohort. Store MailerSend’s message identifier alongside your own event ID. Keep the former provider ready until retries, bounces, and unsubscribe behavior are confirmed.

Seat and domain planning

MailerSend’s two 50,000-message plans make account shape the deciding factor. Count the people who need to edit templates, the domains that need independent authentication, and any SMS usage before choosing Starter or Professional. A five-seat limit can be fine for a product team and awkward for an agency with client reviewers. Write the expected team size into the renewal record so a domain expansion does not become an emergency upgrade.

Keep annual billing visible in cash planning. The monthly equivalent is convenient for comparison, while the yearly totals describe when the money leaves the account. Review cancellation and renewal terms with the same care as the message allowance.

Account-shape note

Make seat, domain, API-request and SMS assumptions visible in the purchase request. The plan with the right email number can still be the wrong account shape if reviewers cannot access templates or a new brand cannot be authenticated.

Competitor cost check

At 10,000 emails, Mailgun Basic starts at $15 and Amazon SES Essentials is 10 × $0.16 = $1.60 in usage charges. At 50,000, Mailgun Foundation is $35 and SES is 50 × $0.16 = $8.00, while MailerSend Starter is $31.50. At 100,000, Mailgun Scale is $90 and SES is $16.00; MailerSend still lists 50,000 on Starter and Professional, so a 100,000 forecast requires a quote or a different plan assumption. These comparisons exclude engineering and support work.

What the email price does not include

MailerSend’s cards specify seats, domains, API requests, and SMS, but they do not promise dedicated IPs, a retention duration, inbound routing, or a premium support response on every plan. Free has one user and one domain; Hobby has five seats and one domain; Starter has five seats and ten domains; Professional lists unlimited users and domains plus 150 SMS. Annual billing is preferable when the $75.60, $378, or $1,188 commitment matches a stable forecast and procurement accepts the cash timing. Monthly billing is safer when team size or domains may change before renewal.
