Pricing as of October 2026. **Verdict.** Mailtrap built its name on the email testing sandbox, and many positive reviews are about that. Its newer sending product has fewer reviews and a few sharp complaints about automatic bans. Mailtrap's Trustpilot page is small: we read all 17 readable reviews (September 2024 to May 2026), 10 five-star, 6 one-star and 1 three-star. We read [Mailtrap's Trustpilot page](https://www.trustpilot.com/review/mailtrap.io) in full and used a summary of Mailtrap's pricing page for plan limits. SendHQ is a competing email API and is mentioned where it differs. Quotes are copied verbatim from the linked pages and attributed by the display name and month shown there. Reviews are self-selected, we cannot verify individual claims, and a complaint is not a finding about the company. ## What users praise about Mailtrap - A May 2026 reviewer wrote: they were one of the first to offer email sandboxes, it works great for testing! Another, on the sending product, said The SMTP setup was actually pretty quick and the Node SDK just worked without any problems. - That reviewer reports sending around 450,000 messages a month, which is one data point rather than a benchmark. ## Mailtrap complaints: common themes ### Automatic bans and review holds (at least 4 of 17) A May 2026 reviewer wrote of an automatic ban without having any options to change any settings after a 0.1% delivery issue. A March 2026 reviewer migrating transactional mail said they were rejected by an automated bot within minutes. Another reviewer said Mailtrap blocked our ability to send marketing emails. ### Free plan limits As of October 2026 Mailtrap's free plan is 4,000 emails per month with a 150 per day cap and 1 domain. A 2025 reviewer called the 150 per hour limit on a basic plan too less; limits may have changed. ## Mailtrap pricing (as of October 2026) Mailtrap's [pricing page](https://mailtrap.io/pricing/) is rendered by scripts; a fetch on 1 October 2026 listed, for Email API/SMTP: Free with 4,000 emails per month, 150 per day and 1 domain; Basic from about $15 per month (10,000 to 100,000 emails, 5 domains); Business from about $85 per month (100 domains); Enterprise from about $750 per month.
