Mailtrap Pricing Review: What You’ll Pay for Email Testing in 2025

Mailtrap started as a simple email testing tool but has grown into a full email delivery platform used by over 150,000 people monthly, including PayPal, Atlassian, and Adobe. 

What makes it interesting? They’ve kept their testing roots while building out production email sending — kind of like having a practice field and the main stadium in one place. The pricing spans from a pretty generous free tier all the way up to enterprise deals, which sounds standard enough, but there’s more nuance when you dig in.

Mailtrap Pricing Overview

Here’s the thing about Mailtrap’s pricing: they split it between Email API/SMTP (for actually sending emails) and Email Sandbox (for testing), though you don’t need both for basic campaigns. The smart bit? They charge by email volume, not contacts. So if you’ve got 50,000 subscribers but only email them once a month, you’re golden.

One subscription covers both transactional and marketing emails — no juggling multiple plans. Annual subscriptions knock off 20%, which adds up if you’re sending serious volume. They take the usual payment methods: credit cards, PayPal, and bank transfers for the big enterprise folks. No sneaky setup fees, though watch those overage charges if you blow past your monthly limit.

Mailtrap Monthly Pricing

The free tier gives you 3,500 emails monthly — honestly, one of the better free deals out there. Basic plans start at $10/month for 10,000 emails and scale up to $50 for 100,000 on that same tier. 

But here’s where it gets interesting: the Business tier (starting at $85/month for 100,000 emails) is where most growing companies land. Why? Dedicated IPs, better support, longer log storage — the stuff that matters when email becomes mission-critical.

For testing, Email Sandbox runs from free (50 test emails) up to enterprise levels. Most dev teams find the $15/month Team plan hits the sweet spot. You can adjust your plan month-to-month based on what you actually need, which beats being locked into something that doesn’t fit.

Mailtrap Monthly Plans

Free Plan

You get 3,500 emails monthly with a 150 daily cap on the free plan. Perfect for side projects or testing the waters. You’re limited to one domain and 100 contacts, plus logs only stick around for three days.

Basic Plan

Basic comes in three flavors: 10K emails ($10), 50K ($25), or 100K ($50) monthly. Contact limits scale accordingly — 5,000 to 50,000. You get five domains, three user seats, and logs hang around for five days. Pretty reasonable for a growing startup.

The real value? Email templates and bulk sending unlock here. Overages run $1 per thousand emails, which won’t kill your budget if you occasionally spike.

Business Plan

Business tier runs from $85/month (100K emails) up to $425 (750K emails). This is where things get serious. Dedicated IP with automatic warm-up? Check. Support for 3,000 domains and 1,000 users? Yep.

Logs stick around for 15 days, email bodies for 7 — crucial when you’re debugging that one weird delivery issue. Overages drop to $0.88 per thousand, better than Basic tier. The SSO integration and deliverability safeguards make sense at this scale.

Enterprise Plan

Enterprise pricing is custom, typically for folks sending over 1.5 million emails monthly. You’re looking at 2.5 million+ contacts, unlimited users, the works. But the real draw? A dedicated deliverability manager — basically someone whose job is keeping your emails out of spam folders.

They’ll migrate you for free if you’re sending over 200K monthly. Logs stay for 30 days, plenty of time for compliance audits. Custom SLAs, dedicated support, all that enterprise stuff.

Mailtrap Pay-as-you-go Plan

Mailtrap doesn’t have traditional pay-as-you-go like some competitors. Instead, they use overage pricing — $1 per thousand on Basic, down to $0.55 on Enterprise. It’s actually pretty clever. You pick a base plan, and if you go over, they just bill the extra. No pre-buying credits.

Sender, for example, charges $29 for 5,000 pay-as-you-go emails. For sporadic senders, that might work better. But if you’re consistently sending with occasional spikes? Mailtrap’s overage system probably saves you money; it just depends on your sending patterns.

Mailtrap Transactional Emails Pricing

Here’s something refreshing: Mailtrap doesn’t split pricing between transactional and marketing emails. One quota, one price. Simple. They do keep the streams separate technically though — bulk emails won’t mess with your transactional delivery, which matters when you’re sending password resets.

At $10/month for 10,000 emails, they’re competitive with Postmark ($15 for the same volume). The platform gives you 25+ code snippets to get started quickly. Webhooks, detailed SMTP logs, millisecond tracking — all the stuff developers need for order confirmations and system alerts.

Mailtrap SMS Pricing

Short answer? They don’t do SMS. Unlike Mailjet which handles both email and SMS, Mailtrap sticks to email only. Is that a problem? Depends what you need.

If you need both channels in one place, consider tools like Sender, which integrates text messaging on the same dashboard as their email campaigns. But if you’re email-focused, Mailtrap’s specialization means you’re not paying for features you won’t use. Their API plays nice with third-party SMS services if you need to add it later, though that’s another integration to manage.
