Three products with separate free plans: sending, a testing sandbox and marketing. Mailtrap sells three separate products, each with its own free plan: Email API and SMTP for sending, Email Sandbox for testing and Email Marketing for campaigns. The sending Free plan gives 4,000 emails a month with a 150 per day cap, 1 user, 1 domain and 3 days of logs, and the pricing FAQ says no credit card is required. Basic is $15 a month for 10,000 emails, $20 for 50,000 and $30 for 100,000, and Business starts at $85 for 100,000 with a dedicated IP. The Sandbox Free plan allows 50 test emails a month. G2 shows 4.8 from 77 reviews and Capterra shows 4.8 from 36, with praise for ease of use and delivery. Trustpilot reviewers also report an account removed without warning and an automated rejection during a migration attempt, so test before you move production mail.

👍 Good boy
+One account covers sending, testing and marketing, with a free plan for each. The sandbox catches test mail so it never reaches real recipients.
+4,000 free sending emails a month with no credit card, per the FAQ, is a useful allowance for early-stage and staging use.
+G2 reviewers rate ease of use first and one wrote that SMTP setup was smooth and delivery fast and dependable. G2 shows 4.8 from 77 reviews.
+A Trustpilot reviewer said they send around 450k messages a month and Mailtrap handles that volume without any noticeable lag.
+Another Trustpilot reviewer said Mailtrap was one of the first to offer email sandboxes and that it works great for testing.
+Business adds a dedicated IP, 24/7 email and live chat support, 100 users and 15 days of logs. Mailtrap lists SOC 2 Type 2 and ISO 27001.
+Hitting the monthly limit returns a clear SMTP error, "535 5.7.0 Monthly messages limit reached", and you upgrade or wait for the next period.
👎 Watch out
−The Free plan is capped at 150 emails a day and keeps logs for 3 days, which is short for debugging a delivery problem.
−A Trustpilot reviewer wrote that Mailtrap can remove your account at any time without warning, and another said an automated bot rejected their migration of transactional mail within minutes.
−Mailtrap says in a reply on Trustpilot that it applies compliance and anti-abuse checks to protect deliverability. Expect a check when you move real traffic.
−A Trustpilot reviewer who was otherwise happy said the email logs on lower plans are a bit tight.
−Click tracking and HTTPS link branding are not on Free, per the comparison table, and dedicated IP and auto warm-up start at Business.
−Sending, Sandbox and Marketing are sold separately, so a team that uses all three manages three plans.
−Free and Basic support is email only on weekdays. Live chat and 24/7 support start at Business.
The catch
Mailtrap is three products. The pricing FAQ says they are sold separately and each has a free plan: sending (4,000 emails a month), sandbox (50 test emails) and marketing (500 contacts, 1,500 emails).
The sending Free plan has a 150 per day cap and 3 days of logs. That fits a side project or a staging environment and gets tight on a busy day.
Trustpilot reviewers describe two risks worth testing: an account removed without warning, and an automated rejection when migrating transactional mail. Mailtrap says it applies compliance and anti-abuse checks to protect deliverability. Send a small, clean batch first and keep a second provider ready.
Hitting your monthly limit returns an SMTP error until you upgrade or the next period starts.
