Mailgun pricing in 2026, broken down by plan and overage

Mailgun has four public Send tiers, and the advertised price is only the starting point. The plan that looks cheapest can become more expensive than the next tier once the included volume, overage rate, validation use, and dedicated-IP requirement are part of the calculation. This guide separates those line items so a team can quote the workload it actually has.

All Mailgun figures in this article were verified against the live Mailgun pricing page as of August 2026. Mailgun can change plans, allowances, and rates, so recheck that source before buying.

The short answer

Mailgun Send is publicly listed as Free at $0 with 100 emails per day, Basic from $15 per month with 10,000 emails included, Foundation at $35 per month with 50,000 included, and Scale at $90 per month with 100,000 included. The same live page lists email overages from $1.80 per 1,000 on Basic, $1.30 per 1,000 on Foundation, and $1.10 per 1,000 on Scale. Mailgun pricing is the source for every number in this guide.

The practical choice is usually volume-shaped. Free is a capped way to test the API. Basic is the first paid tier and has one custom sending domain. Foundation adds the broader routing, template, retention, and domain allowances shown on Mailgun's feature matrix. Scale is the public 100,000-email tier, with a lower listed extra-email rate and features such as SAML SSO, send-time optimization, and dedicated IP pools. Mailgun pricing

Mailgun Send plans, line by line

Free: $0 with 100 emails per day

Mailgun Free lists $0 per month and 100 emails per day. It includes RESTful email APIs and SMTP relay, one custom sending domain, tracking, analytics, webhooks, two API keys, one day of log retention, and one inbound route. Those are useful fundamentals for an evaluation or a low-volume integration, but the daily cap is the governing allowance. A monthly total depends on the number of calendar days, so it is more accurate to plan around 100 per day than to treat Free as a fixed monthly bundle. Mailgun pricing

Free does not list a monthly overage option, extra custom domains, or more than one inbound route. Mailgun's plan comparison also shows one day of log retention for Free. If any of those constraints are binding, the paid plan rather than a hypothetical Free overage is the relevant comparison. Mailgun pricing

Basic: from $15 per month for 10,000 emails

Basic starts at $15 per month and includes 10,000 emails per month. Mailgun lists no daily email limit, monthly email overage options, RESTful email APIs and SMTP relay, one custom sending domain, tracking, analytics, webhooks, two API keys, one day of log retention, and five inbound routes. The listed extra-email rate starts at $1.80 per 1,000 emails, and validations start at $1.20 per 100 validations. Mailgun pricing

The important boundary is that Basic is a 10,000-email allowance, not a flat $15 price for arbitrary volume. A 50,000-email workload left on Basic uses 40,000 extra emails. At the page's listed starting rate, that is 40 times $1.80, or $72 in overage, plus the $15 base, for $87 before validations or other add-ons. Foundation is therefore the more direct public plan to price at 50,000 emails. Mailgun pricing

Foundation: $35 per month for 50,000 emails

Foundation is listed at $35 per month after a one-month free trial and includes 50,000 emails per month. Mailgun says it adds full access to its RESTful email APIs and SMTP relays, up to 1,000 custom sending domains, the email template builder and API, tracking, analytics, webhooks, five days of log retention, one day of message retention, and full access to inbound routing. Extra emails start at $1.30 per 1,000 and validations at $1.20 per 100. Mailgun pricing

For teams that need routing or multiple domains, those feature boundaries matter as much as the base rate. Mailgun's public comparison shows five inbound routes on Basic and full inbound routing on Foundation. It also shows five days of log retention on Foundation, compared with one day on the two lower tiers. The page is the authoritative place to check the exact entitlement before relying on a route or retention window in production. Mailgun pricing

Scale: $90 per month for 100,000 emails

Scale is listed at $90 per month after a one-month free trial and includes 100,000 emails per month. The pricing page lists SAML SSO, 5,000 email validations, dedicated IP pools, send-time optimization, live phone and chat support, 30 days of log retention, up to seven days of message retention, and scheduled analytics reports. Its listed extra-email rate starts at $1.10 per 1,000, while extra validations start at $0.80 per 100. Mailgun pricing

Scale is not merely Foundation with another 50,000 emails. It changes both the listed usage rate and the included operations features. Still, the displayed $90 is the price for the stated 100,000-email allowance. A workload above that amount should add the applicable extra-email line, and a workload with a specialized enterprise need should request a quote rather than extrapolate the self-serve cards indefinitely. Mailgun describes Enterprise as a tailored service that includes everything in Scale plus custom features, Deliverability Services, and a Rapid Fire Burst Sending SLA. Mailgun pricing

Overage rates and how to calculate them

The pricing page uses the word "from" for paid-plan overage rates: Basic from $1.80 per 1,000 emails, Foundation from $1.30 per 1,000, and Scale from $1.10 per 1,000. Treat those as the published starting rates, not a promise that every customized account or high-volume contract has the same marginal price. Mailgun pricing

For a standard estimate, use this formula: monthly plan charge plus the number of emails over the included allowance, divided by 1,000, multiplied by the plan's listed starting extra-email rate. Keep validation purchases and IP charges as separate lines. That separation prevents a base-plan comparison from quietly excluding the services the workload needs. Mailgun pricing

Mailgun bills the selected monthly plan and any extra emails and validations used for the prior month at the start of the following month, according to its pricing FAQ. Its FAQ also says a new account is billed a prorated amount for the selected plan during the first month. These billing-timing details do not change the monthly run-rate examples below, but they can change the first invoice. Mailgun pricing

Add-ons: validation, dedicated IPs, Inspect, and Optimize

Validate. Mailgun displays validation pricing as an extra line on the paid cards: from $1.20 per 100 validations on Basic and Foundation, and from $0.80 per 100 on Scale. Scale also lists 5,000 email validations as included. If a team validates 10,000 addresses on Basic or Foundation at the listed starting rate, that is 100 blocks of 100 times $1.20, or $120, separate from email sending. Mailgun pricing

Dedicated IPs. Mailgun's comparison indicates dedicated-IP access at 50,000-email volume and a dedicated IP included at 100,000-plus volume. Its pricing FAQ says one dedicated IP is included with Foundation 100k, Growth, and Scale plans, and that additional IPs cost $59 per IP per month. Because the terminology on the page distinguishes the standard 50,000-email Foundation card from a Foundation 100k configuration, confirm the selected volume and entitlement in the account or with Mailgun before treating an IP as included. Mailgun pricing

Inspect and Optimize. The live pricing page identifies Inspect as a Mailgun product and labels Inbox Placement and Reputation Monitoring as available on Optimize. It does not display a standalone public monthly price for Inspect or a public Optimize price on the pricing page at the time of verification. A budget should therefore request the current quote or in-product price for those services instead of carrying forward an old published number. Mailgun pricing

These are separate purchase questions. Email volume determines the Send tier; list hygiene can add validation usage; dedicated reputation capacity can add an IP line; and deliverability testing or monitoring can require an Optimize discussion. Keeping those lines separate produces a usable budget rather than an incomplete estimate. Mailgun pricing

What is not included in the base plan price

A base Send price is not a universal all-in email budget. The Free plan has the daily sending cap, one domain, one inbound route, and one-day logs listed on the page. Basic lists one custom sending domain, five inbound routes, and one-day log retention. Foundation and Scale expand the stated domains, routing, retention, and security features, but their listed base prices do not erase overage usage, validation purchases where applicable, or additional dedicated IPs. Mailgun pricing

The plan cards also do not state a price for the work an application does around email. For example, a product may need its own message data model, application UI, storage policy, observability, or customer support workflow. Those are architecture decisions rather than Mailgun Send line items, so this guide does not invent a universal dollar amount for them. Mailgun itself presents Send, Validate, Inspect, and Optimize as distinct product areas. Mailgun pricing

Worked example: 10,000 emails per month

At 10,000 emails in a month, Basic's $15 base includes the full volume. There is no listed Basic email overage at that exact allowance. Free cannot be treated as a 10,000-email monthly option because it is capped at 100 per day. The $15 estimate excludes any validations, dedicated IPs, or Optimize-related services because those are separate lines. Mailgun pricing

If the workload also validates 1,000 addresses on Basic at the listed starting rate, it adds 10 blocks of 100 times $1.20, or $12. The estimated total then becomes $27 before taxes and any other separately priced service. This is a calculation from Mailgun's published Basic base, allowance, and validation rate, not a bundled price shown by Mailgun. Mailgun pricing

Worked example: 50,000 emails per month

At 50,000 emails, Foundation's $35 base includes the entire volume. The estimated Send charge is $35 before validation, IP, or Optimize lines. Keeping the workload on Basic would be $15 plus 40,000 extra emails at the listed starting rate of $1.80 per 1,000, or $87. The Foundation card is therefore $52 lower on this published-rate comparison at this exact volume. Mailgun pricing

If the team validates 5,000 addresses on Foundation at the listed starting rate, it adds 50 blocks of 100 times $1.20, or $60. The resulting $95 estimate is $35 Send plus $60 Validate, before any dedicated IP or deliverability-service charge. State the two lines separately because validating five thousand addresses is not included in the published Foundation card. Mailgun pricing

Worked example: 200,000 emails per month

At 200,000 emails, the public Scale card contributes $90 for the first 100,000 emails. The remaining 100,000 emails at Scale's listed starting overage rate are 100 times $1.10, or $110. The resulting Send estimate is $200 before validation, IP, or Optimize costs. Because Mailgun labels the rate "from," this is a starting-rate estimate, not a quote. Mailgun pricing

Scale lists 5,000 email validations included. If an additional 10,000 validations are purchased at the displayed starting rate, they add 100 blocks of 100 times $0.80, or $80. That makes the illustrative $280 total: $200 Send plus $80 additional Validate. One included dedicated IP at the selected 100,000-plus configuration would change the IP line, while each additional IP is listed at $59 per month. Mailgun pricing

When Mailgun is the right choice

Mailgun is a reasonable fit when a team wants an HTTP API or SMTP relay, inbound routing, and a volume-based Send plan with clearly published self-serve cards through 100,000 emails. Basic can fit a 10,000-email workload that needs up to five inbound routes. Foundation can fit 50,000 emails when full inbound routing, templates, additional domains, and longer log retention matter. Scale can fit a 100,000-plus workload that values the listed SSO, validation, dedicated-IP-pool, support, retention, and send-time optimization features. Mailgun pricing

The right choice is not determined by the lowest starting price alone. It depends on whether the send volume is steady, whether validation is needed, whether a dedicated IP is justified, and whether the operational features on the selected card match the implementation. Mailgun's public page provides a plan selector and an Enterprise contact path for workloads that do not map cleanly to the four visible cards. Mailgun pricing

Bavimail comparison

Bavimail publishes a different entry shape. Bavimail Pro is $5 per month, or $48 per year with a $4 monthly equivalent, and includes 50,000 emails per month. Bavimail Startup is $50/mo ($492/yr) and includes 300,000 emails per month. Those are Bavimail's disclosed prices, not Mailgun prices, and the product scope should be evaluated alongside the plan numbers.

At a 50,000-email monthly workload, Mailgun Foundation's listed base price is $35 before separate validation or other add-on lines, while Bavimail Pro's disclosed price is $5 per month for its stated 50,000-email allowance. At 200,000 emails, Mailgun Scale's published starting-rate Send estimate is $200 before its separate lines, while Bavimail Startup's $50/mo ($492/yr) plan includes up to 300,000 emails per month, so the 200,000-email workload is within its stated allowance. Check Bavimail pricing and the live Mailgun pricing page for the current scope and rates before selecting either platform.
