Mailgun pricing, explained: every plan and what it costs
Mailgun is free for 100 emails a day. Paid plans start at $15 a month for 10,000 emails (Basic), $35 for 50,000 or $75 for 100,000 (Foundation), and $90 to $1,250 for 100,000 to 2.5 million (Scale). Extra emails cost from $1.80 per 1,000 on Basic down to $0.40 on the largest Scale tier. Validations and the Optimize deliverability tools are priced separately.
We build SendForAI, an email API that runs on Amazon SES at cost, so we're not neutral. Every Mailgun number below comes from Mailgun's own pricing pages, read November 7, 2026, and there's a section on where Mailgun is the better choice.

What each plan costs at your volume
Mailgun bills overage per 1,000 extra emails, so you can stay on a smaller plan and pay overage, or move up a tier. This table takes the cheaper of the two on each plan family, so you can see what staying on a plan costs as you grow.
| Emails / month | On Basic | On Foundation | On Scale | Cheapest Mailgun option | SendForAI |
|---|---|---|---|---|---|
| 10,000 | $15 | $35 | $90 | $15 (Basic 10k) | $5 |
| 50,000 | $87 | $35 | $90 | $35 (Foundation 50k) | $9.40 |
| 100,000 | $177 | $75 | $90 | $75 (Foundation 100k) | $14.90 |
| 250,000 | $447 | $240 | $215 | $215 (Scale 250k) | $31.40 |
| 500,000 | $897 | $515 | $400 | $400 (Scale 500k) | $58.90 |
| 1,000,000 | $1,797 | $1,065 | $700 | $700 (Scale 1M) | $113.90 |
| 2,500,000 | $4,497 | $2,715 | $1,250 | $1,250 (Scale 2.5M) | $333.85 |
Monthly USD before tax, overage billed in whole blocks of 1,000. SendForAI is $5 in a month you send (10,000 emails included), then $0.11 per 1,000; over a million it adds a dedicated IP at AWS's price and $0.02 per 1,000 for infrastructure.
Three things the table shows
- Basic is only for small volumes. At $1.80 per 1,000 extra emails, Basic costs more than Foundation 50k ($35) once you pass about 21,000 emails a month.
- At 100,000 emails, Foundation is $15 cheaper than Scale. Same volume, $75 against $90. Scale's extra $15 buys 30-day logs instead of 5, 5,000 email validations, SAML single sign-on, dedicated IP pools and live phone and chat support.
- Foundation stops at 100,000. Above that it's overage at $1.10 per 1,000, and from about 228,000 emails a month the Scale tiers are cheaper.
Add-ons: validations and Optimize
Email address validation is sold per 100 checks: from $1.20 per 100 on Basic and Foundation, and from $0.80 per 100 on Scale, which also includes 5,000 a month. Mailgun Optimize, its deliverability toolkit, is a separate subscription:
- Pilot: $49 a month, 2,500 validations and 25 inbox placement tests.
- Starter: $99 a month, 5,000 validations and 50 inbox placement tests.

Where Mailgun is the better choice
- You receive email too. Mailgun includes inbound routing on every plan (5 routes on Basic, full routing from Foundation). SendForAI only sends.
- You want SMTP. Every Mailgun plan, Free included, has an SMTP relay, so older apps and plugins work unchanged. SendForAI is API-only.
- You need validation and deliverability tooling in one place. List validation, inbox placement tests, 30-day logs, single sign-on and phone support are all available. SendForAI has none of those and is in early access: payments run in test mode and our Amazon SES production access is under review.
If you mostly send, the gap is price: $75 against $14.90 at 100,000 emails a month, and $700 against $113.90 at a million. See Mailgun alternatives for SendGrid, Postmark, Resend and Amazon SES at the same volumes, or SendForAI pricing.
Mailgun pricing FAQ

How much does Mailgun cost for 100,000 emails a month?
$75 a month on Foundation 100k, or $90 on Scale 100k. Scale costs $15 more for the same volume and adds 30-day logs instead of 5, 5,000 email validations, SAML single sign-on, dedicated IP pools and live phone and chat support.

Basic charges from $1.80 per 1,000 extra emails, Foundation from $1.30, and Scale from $1.10, falling to $0.40 per 1,000 on the 2.5 million Scale tier. Overage makes Basic expensive fast: past about 21,000 emails a month, Foundation 50k at $35 is cheaper.
Does Mailgun include a dedicated IP?
Mailgun's pricing FAQ says one dedicated IP is included with Foundation 100k and Scale plans, and extra IPs cost $59 per IP per month. Scale also supports dedicated IP pools.
Does Mailgun still have the Flex pay-as-you-go plan?
Not on its current pricing page. Older reviews describe a Flex plan with a free trial and per-1,000 pricing; today's self-serve options are Free, Basic, Foundation and Scale, with Enterprise by quote.
Is there a cheaper alternative to Mailgun?
Amazon SES directly costs about $0.10 per 1,000 emails if you build bounce handling, suppression and unsubscribe yourself. SendForAI runs on SES with those built in: $5 in months you send includes 10,000 emails, then $0.11 per 1,000. See our Mailgun alternatives comparison for SendGrid, Postmark and Resend too.
