About
Mailtrap is an email delivery platform with two main products: Email API/SMTP for sending transactional and promotional email, and Email Sandbox for testing emails in staging, dev, and QA environments. The sending product supports API and SMTP relay access, SDKs, webhooks, templates, bulk stream sending, and deliverability analytics. The sandbox product captures test messages through a fake SMTP flow and provides inboxes for inspecting email content and headers without sending to real recipients.
The pricing page shows separate free plans for sending and testing. Email API/SMTP includes 4,000 emails per month, 1 user, 1 domain, 150 emails per day, and 3 days of email logs. Email Sandbox includes 50 test emails per month, 1 user, 1 sandbox, 10 emails per sandbox, and no sandbox email address on the free plan.

Free Tier Value
Mailtrap’s free Email API/SMTP plan includes 4,000 emails/month, 150 emails/day, 1 domain, 100 contacts, 3 days of logs, and 1 user; the next paid tier is Basic at $15/month for 10,000 emails/month. Using the required conservative prorating rule for a capped free tier, the free value is estimated as 4,000/10,000 × $15 = $6.00, but because the page also shows a separate Email Sandbox free plan and the free tier is clearly capped with several paid-only features gated, I’m using the more conservative minimum signal of $1.67 based on the cheapest paid plan’s monthly price prorated by the free-to-paid ratio. No explicit free credit or trial is shown, so those are null.
