Mailgun Pricing: How Much It Really Costs in 2025

Here’s the thing about Mailgun pricing—it’s not as straightforward as you might hope. The company offers several plans with different email volumes and features, but figuring out what you’ll actually spend can get tricky once you start adding things up.

I’ve spent time digging through their current pricing structure to give you the real picture. Whether you’re sending a few hundred emails or millions, this guide will help you understand what each plan costs and what you actually get for your money.

Mailgun Pricing Overview

Mailgun charges based on how many emails you send, not how many contacts you have. That’s different from platforms like Sender.net, and it can work in your favor if you have a big list but don’t email them constantly.

The pricing starts with a limited free plan and goes up to custom enterprise deals. You’ll find four main monthly plans plus a pay-as-you-go option for businesses with unpredictable sending patterns. What catches people off guard is that many useful features—like email validation and dedicated IP addresses—are locked behind the more expensive plans.

They bill monthly and prorate upgrades, which is nice. But watch out for overage charges when you exceed your plan’s email limit. The good news? They don’t charge per user, so your whole team can access the account without extra fees.

Mailgun Monthly Pricing

Monthly plans work best if you send emails regularly and want predictable costs. Each plan includes a certain number of emails, plus you can buy extra volume at discounted rates when you go over.

The monthly approach gives you access to features like analytics, API access, and basic support right away. But if you want the really useful stuff—send time optimization, email validation, dedicated IPs—you’ll need to jump up to the pricier tiers.

Enterprise pricing kicks in when you need more than 2.5 million emails monthly. At that point, you’re looking at custom quotes and dedicated account managers. It provides cost certainty, though you might end up paying for emails you don’t use during slower months.

Mailgun Monthly Plans

Free Plan

The free plan gives you 100 emails per day without requiring a credit card. It’s perfect for testing things out or handling basic notifications for small apps—think password resets or account confirmations.

You get one domain, basic API access, and email tracking. But the logs only stick around for one day, and support is ticket-only with potentially slow response times. You can’t exceed that daily limit either, so forget about any marketing campaigns.

It’s genuinely useful for development and proof-of-concept work. Just don’t expect to run a real business on it for long.

Foundation Plan

At $35 monthly for 50,000 emails, Foundation is where things get serious. You get email templates, inbound routing, and logs that stick around for five days instead of one. The big win is support for 1,000 custom domains—handy if you’re managing multiple brands or client accounts.

Extra emails cost $1.00 per thousand, which isn’t terrible. You also get webhooks for real-time tracking and 24-hour message retention. But you’re still on shared IP addresses with no email validation features.

This plan works well for small businesses with steady email needs. If you’re sending order confirmations, newsletters, or customer updates regularly, Foundation probably makes sense.

Scale Plan

Scale jumps to $90 monthly for 100,000 emails, but you get some genuinely useful upgrades. Email validation (5,000 validations included), dedicated IP addresses, and send time optimization that uses machine learning to figure out when people actually read their email.

The support improves to live chat, logs stick around for 30 days, and you get inbox placement testing. Additional emails drop to $0.80 per thousand. The dedicated IP is huge if you’re worried about sender reputation—you’re not sharing with other Mailgun users who might mess things up.

This tier makes sense for e-commerce sites, SaaS apps, or anyone who needs reliable delivery and can’t afford emails ending up in spam folders.

Enterprise Plan

Enterprise pricing is custom, starting around 2.5+ million emails monthly. You get everything from Scale plus dedicated account managers, deliverability consulting, and guaranteed SLAs for uptime and performance.

They’ll customize IP pools, routing, and basically whatever you need. The catch? You’re looking at serious money and probably need a dedicated technical team to make the most of it.

Most businesses never need this level of service. But if you’re processing millions of transactions or running a platform with thousands of users, the custom approach starts making sense.

Mailgun Pay-as-you-go Plan

The Flex plan is pay-as-you-go after three free months. You pay $0.80 per thousand emails with no monthly minimums or commitments. It’s perfect if your email volume bounces around unpredictably.

You get full API access, unlimited daily sending, and the same tracking features as Foundation. No monthly fees unless you’re actually sending emails. The downside? You’re still on shared IPs with limited support options.

This works great for seasonal businesses, startups testing ideas, or anyone who can’t predict their email needs. But if you’re sending consistently, monthly plans usually work out cheaper.

Mailgun Transactional Emails Pricing

All plans handle transactional emails—those automated messages like order confirmations, password resets, and account notifications. The per-email costs are the same whether you’re using monthly plans or pay-as-you-go.

Higher-tier plans add features that actually matter for transactional email: send time optimization, email validation, and dedicated IPs. These help ensure your important messages actually reach people instead of getting stuck in spam folders.

The webhook system lets you track delivery status in real-time, which is crucial for things like password resets where you need to know if the email made it. Dedicated IPs in Scale and Enterprise plans provide reputation isolation—important when you’re sending thousands of account notifications daily.

SMS Pricing

Here’s something that might surprise you: Mailgun doesn’t offer SMS services. They focus entirely on email delivery. If you need text messaging alongside email, you’ll have to integrate with a separate SMS provider.

Most Mailgun users who need SMS end up pairing it with services like Twilio or AWS SNS. You can use Mailgun’s webhooks to trigger SMS messages when emails fail or for multi-channel campaigns, but it requires separate billing and technical setup.

Platforms like Sender.net offer both email and SMS in one package, which might be simpler if you need both. But Mailgun’s email specialization means better deliverability and more technical flexibility—you just lose the convenience of unified billing.
