MailerSend Pricing Plans and Cost Per 1,000 Emails at Every Volume

MailerSend costs $7 a month for 5,000 emails on Hobby, $35 a month for 50,000 on Starter and $110 a month for 50,000 on Professional. Starter climbs to $600 for 1 million emails and Professional to $1,600 for 2 million. Paying yearly takes 10% off Starter and Professional and 20% off Hobby. The free plan sends 500 emails a month and still asks for a card.

Those numbers come from the plan data behind MailerSend's own pricing slider, which the page fills in with a script, so the static page text alone shows blank prices. The cost per 1,000 emails, the upgrade thresholds and the yearly totals further down are our arithmetic on that data.

Billing is in US dollars even when you switch the page to euros or pounds. MailerSend says taxes may apply on top.

Starter has five volume steps, from 50,000 to 1 million emails. Professional has seven, from 50,000 to 2 million. Starter stops at 1 million, so a sender above that is moved to Professional whether or not they want the extra features.

Yearly prices are the monthly figure less 10%, which is how MailerSend's own pricing script calculates them. Hobby is the exception: $5.60 a month billed as $67.20 a year, a 20% saving against $7, even though the toggle above the cards says "Save 10%".

On Starter, MailerSend costs $0.70 per 1,000 emails at 50,000 a month, $0.68 at 100,000 and $0.60 at 1 million. On Professional it costs $2.20 per 1,000 at 50,000 and falls to $0.80 at 2 million. Hobby works out at $1.40 per 1,000 if you use all 5,000 emails.

Starter is close to flat across its range: the unit price only drops by a dime between 50,000 and 1 million. Professional starts expensive and gets steadily cheaper, because what you pay for at the bottom is seats, domains, retention and an account manager rather than volume. At 50,000 emails Professional costs $75 more than Starter. At 1 million the gap is $400.

Extra emails cost $1.50 per 1,000 on Hobby and $1.30 per 1,000 on the 50,000 and 100,000 steps of both Starter and Professional. Higher steps carry cheaper overage, down to $1.00 on Starter at 1 million and $0.50 on Professional at 2 million. MailerSend keeps sending once you pass your allowance and bills the extra blocks of 1,000.

Overage is always dearer than the plan rate, so the useful number is where moving up a step becomes cheaper than paying for extras. Our arithmetic on the published rates:

The Hobby line matters most for small senders. A product that sends 15,000 emails a month pays $7 plus 10 blocks at $1.50, so $22 on Hobby, which is still cheaper than Starter's $35. At 30,000 a month Hobby comes to $44.50 and Starter wins.

MailerSend has a free plan with 500 emails a month, 1 sending domain, 1 template, 1 user plus an accountant role, 1 API token and 1 webhook. The plan card lists 1,000 API requests a day while the FAQ says 100, so plan on the lower figure. MailerSend asks for card details even on the free plan, which its FAQ says is to prevent abuse, and it says the free plan is not charged.

There is also a 14-day trial of Professional features. Both are built for testing an integration, not for running production mail: 500 emails a month is about 16 a day. For a business with real volume the decision is between Hobby at $7 and Starter at $35, and the threshold above tells you which.

Two other terms are worth knowing before you pay. MailerSend's terms say refunds are not given if you buy the wrong monthly or yearly plan, even by mistake, so check the volume step before choosing yearly. And the nonprofit discount it offers cannot be stacked with the yearly price.

MailerSend sells extra sending domains at $4.00 each, US and Canada phone numbers for SMS at $2.00 each, longer activity retention from $5.00 and DMARC monitoring at $2.00 per domain. Dedicated IPs are quoted by its team and are reserved for Enterprise accounts that send more than 100,000 emails a week.

Plans also carry email verification credits and SMS allowances that grow with the volume step. At 50,000 emails, Starter includes 100 verification credits and 100 SMS, and Professional includes 400 credits and 150 SMS. At 1 million emails the figures are 2,500 credits on both, with 7,000 and 10,000 SMS.

At 50,000 emails a month MailerSend Starter costs $35, against $19.95 on SendGrid Essentials, $20 on Resend Pro, $30 on SMTP2GO and $55 on Postmark Basic. At 100,000 a month it costs $68, roughly double Resend Pro and SendGrid Essentials at about $35, and below Postmark's $115 step for 125,000.

MailerSend is not the cheapest relay per email. What the price buys is a combined email and SMS account, a drag and drop template builder, inbound routing and 5 seats on Starter. If your mail is purely developer-sent transactional email, Resend and SendGrid are cheaper at these volumes. Detailed breakdowns are on our Resend pricing, SendGrid pricing and Postmark pricing pages.

No. MailerSend's terms say it is not acceptable to send emails to recipients whose data was purchased, rented or acquired from a third party, and marketing email requires the recipient's consent. A cold prospect list fails both tests.

The terms also let MailerSend terminate an account that draws abuse complaints above its allowed level, without a refund. That is the real cost of trying it: a shared relay protects its IP reputation for every other customer, so it closes accounts that put it at risk. SendGrid, Postmark, Mailgun, SMTP2GO and Amazon SES take the same position, which we cover in whether you can use SendGrid for cold email.

Cold outreach goes out from mailboxes you own. A Google Workspace or Microsoft 365 inbox on your own domain sends at a human pace, and the reputation it builds is yours. ColdMailer is built for that setup: you connect your inbox, import prospects, and it writes one personalized email per person, runs the follow-ups in the same thread and caps each inbox's daily sends. Our guide to the best SMTP server for cold email compares the mailbox options, and the SMTP email sender page shows how the connection works.
