Where can I find my Mailgun invoices?

They live under Account then Billing in the Mailgun control panel at app.mailgun.com/app/account/billing. The Invoices tab inside that page lists every monthly invoice with its date, amount, and status. Each row has a download link for the PDF. There is no separate billing portal outside the app, so an Admin with billing access is the only way in.

Does Mailgun send invoices by email automatically?

Yes. Mailgun emails the invoice PDF (or a link to it) to the billing contact on the account after each successful charge. If the wrong person is getting the email, update the billing contact in Account Settings, not the login email. The two are separate fields. Adding an extra billing contact so your accountant gets a copy directly is supported on the Growth plan and above.

What is the difference between Mailgun's plan fee and my overage charges?

The plan fee is the fixed monthly subscription for Foundation, Growth, or Scale, which includes a set number of emails per month. Overage charges apply when you send more than the included volume, billed per thousand additional messages at your plan's overage rate. Both numbers appear on the same invoice as separate line items, and both are prorated when you upgrade or downgrade mid-cycle. The Flex pay-as-you-go tier skips the plan fee entirely and charges per thousand sent.

How are dedicated IP add-ons billed on Mailgun?

Each dedicated IP is a flat monthly fee on top of your plan, added to the same invoice as a separate line item. If you run more than one dedicated IP for sender reputation isolation, every IP shows as its own line. Cancelling a dedicated IP stops the charge at the end of the current billing cycle, not immediately, so expect one more invoice to include it after you click cancel. Dedicated IPs are not available on Foundation or the free tier, which is why they tend to appear in the invoice detail only once you move up plans.

Why does Mailgun charge me separately for email validation?

Mailgun Validations is a standalone product, priced per validated address, and metered independently of your sending volume. Validating a list of 50,000 addresses will add a validation line item to your monthly invoice, on top of any regular sending charges. The cost is separate from your plan's included volume, so a single list cleanup in an otherwise quiet month can produce a larger invoice than months of normal traffic. Budget for it when you plan a migration or an audit.

Why is my Mailgun invoice billed by Sinch AB instead of Mailgun?

Sinch acquired Mailgun in 2021, and accounts provisioned or renewed under the integrated billing model are invoiced by Sinch AB, a Swedish entity. This matters for European customers because VAT is handled under Swedish tax rules, and the reverse-charge mechanism applies if you supply a valid EU VAT ID. Older accounts created before the integration may still see Mailgun Technologies, Inc. (a Texas entity) as the seller, with US sales tax rules in play. Check the seller field on the PDF before entering the invoice into your accounts.

How can I avoid surprise Mailgun invoices from a usage spike?

Mailgun supports spend alerts under Account then Billing then Alerts. You set a monthly spend threshold and a percentage trigger, and Mailgun emails the billing contact when usage crosses it. The alert does not cap sending, so the invoice will still land, but you get warning in hours instead of at month-end. Pair that with a webhook on the Mailgun API to track real-time volume if you run promotions, viral sign-up flows, or anything where traffic can 10x overnight.

Can my accountant see Mailgun invoices without full sending access?

Yes. Mailgun supports user roles under Account then Users. Grant the accountant the Billing Admin role, which gives access to the Billing section without the permissions to create domains, rotate API keys, or send email. Not every Mailgun plan exposes granular roles, so on smaller plans the practical answer is to forward the PDFs through Inbox Ledger rather than invite the accountant into the product.

How far back does Mailgun keep invoice history?

Invoices are generally visible in the Billing History for the life of the account, but Mailgun does not publish a formal retention guarantee beyond the standard accounting window. Treat the dashboard as a working archive, not a permanent record. For tax and audit purposes, keep your own copies in an accounting system with multi-year retention. A cancelled or downgraded account can lose access to the invoice tab altogether, which is the worst time to discover you never downloaded the PDFs.

Can I pull Mailgun invoice PDFs through the API?

The Mailgun API exposes sending, logs, validations, and analytics endpoints, but it does not return billing PDFs directly. You can pull usage data to reconcile your own spend, but actual invoice documents only exist through the control panel UI. Finance teams with significant Mailgun volume either download each PDF by hand every month or connect the account to an automation layer that captures the PDFs on delivery. The API is useful for cost-optimization work like spotting which domains or routes are pushing you over plan, but not for the PDFs themselves.

My Mailgun invoice is higher than expected. Where should I look first?

Start with the invoice detail and confirm the plan fee is what you expect. Then check the overage line against your Analytics dashboard for the same period. Next, look for a dedicated IP line item that may have been added by a teammate, or an email validation batch that ran mid-month. If all of those match, drop into the Logs and filter by domain to see which sender drove the volume. Most surprise invoices come from a single misconfigured retry loop or a sign-up flow that dual-sends notifications, both of which are visible in the logs once you know to check.

What is the difference between a Mailgun invoice and a Sinch invoice?

If your Mailgun account is billed by Mailgun Technologies, Inc., you receive a Mailgun-branded invoice with Texas sales tax rules. If your account has been migrated to Sinch AB billing, you receive a Sinch-branded invoice for the same service, with EU VAT rules and a Swedish tax ID. The product, the PDF layout, and the line items are effectively identical. The difference matters only for your accounts payable records, where the vendor name on the invoice must match the vendor record you reconcile against. Many finance teams end up maintaining both entities for one or two cycles during the transition and then retire the old one.

How to get Mailgun invoices

Step-by-step guide to downloading your Mailgun billing documents.

Step-by-step: download invoices from Mailgun

1
Sign in to the Mailgun control panel
Go to app.mailgun.com and sign in with the email that owns the account. If your team uses SSO through Sinch, pick the Mailgun workspace from the account switcher. Billing is account-scoped, not domain-scoped, so you do not need to pick a sending domain to see invoices. You do need a role with billing access, which is Account Admin by default. Developer and Support roles are locked out of the Billing section entirely.
2
Open Account then Billing
Click your profile icon in the top-right, choose Account from the menu, then pick Billing in the left sidebar. The direct URL is app.mailgun.com/app/account/billing. This page shows your current plan (Foundation, Growth, Scale, or pay-as-you-go Flex), the primary payment method, the next renewal date, and the running spend since the last cycle. If your account was created before the Sinch acquisition, the layout is the same but the billing entity has changed.
3
Go to the Invoices tab
Inside Billing, click the Invoices tab (sometimes labelled Billing History depending on the rollout). You will see a table of monthly invoices covering the plan fee plus any overages and add-on purchases. Dedicated IP charges, extended log retention, email validations bought through the Validation product, and Mailing Lists overages each appear as separate line items on the same invoice, not as separate documents.
4
Download each invoice as PDF
Click the invoice number or the download icon on the row to save the PDF. Mailgun issues the PDF through its own billing system, with either Mailgun Technologies, Inc. or Sinch AB listed as the seller depending on your region and when the account was provisioned. Invoices in the system typically go back to account creation, but archive retention is not guaranteed beyond the standard accounting window, so keep your own copies.
5
File by month and cross-check with API usage
Use a naming pattern like date plus Mailgun plus amount so the PDFs sort chronologically next to your other transactional email vendors. For any month where the bill jumps, open the Logs and Analytics sections and match the volume line on the invoice against the sent counts on your domains. Viral sign-up spikes, a rogue retry loop, or a validation batch can add hundreds of dollars in a single night and you want the reconciliation trail before the question comes up.

About Mailgun billing

Mailgun gets your transactional email delivered at API speed. The billing side moves at its own pace, and it costs you time every single month.

If you run Mailgun on a Growth or Scale plan with a dedicated IP, extended log retention, and the occasional validation batch, one invoice carries four or five different economic stories. Pull it apart carefully or your reconciliation next quarter will be a scavenger hunt.

Mailgun has been owned by Sinch since 2021. Accounts provisioned after the integration are billed by Sinch AB in Sweden, which applies EU VAT rules. Older accounts are still billed by Mailgun Technologies, Inc. in Texas under US sales tax. Check the seller field on every PDF before you file it, because your accountant will treat Sinch AB and Mailgun Technologies as two separate vendors whether you want them to or not.

About Mailgun

Mailgun, founded in 2010 and acquired by Sinch in 2021, is a transactional email API aimed at developers who need programmatic control over sending, tracking, and validating email. The product covers SMTP relay, HTTP API sending, inbound routing, Mailing Lists, suppression management, and the standalone Mailgun Validations service for list hygiene. Plans include Foundation, Growth, and Scale subscription tiers, plus a pay-as-you-go Flex option that skips the monthly fee. Billing is account-level and monthly, with plan fees, message overages, dedicated IP add-ons, log retention tiers, and validation charges all consolidated into one invoice per cycle.

Why people stop doing this by hand

One Mailgun account on a flat Foundation plan with no overages, no dedicated IP, and no validations is a tidy monthly invoice. Pull the PDF, file it, done in ninety seconds.

The pain starts the moment your product grows. Dedicated IPs get added for deliverability. Log retention gets extended for compliance. A single validation batch runs before a big campaign. A viral sign-up spike pushes you into overage territory for half the month. Every one of those events makes the invoice more interesting to reconcile and more annoying to explain to finance when the charge lands.

Developers face a specific version of this problem. The Mailgun API exposes everything you could want for cost engineering: sent counts by domain, log retention settings, validation usage, webhook-level delivery data. What it does not expose is the invoice PDF itself. So you can build elegant dashboards that predict the bill and still have to click through the control panel to download the actual document your accountant needs. Six months of that and most teams decide the time is better spent on product work.

Sinch billing migration is the quieter headache. Accounts cutting over to Sinch AB get new vendor records in every accounting system they touch, and the old Mailgun Technologies records have to be kept open for the audit trail on pre-migration charges. During the overlap, one Mailgun account can produce invoices from two different legal entities in the same quarter. That is a reconciliation problem no amount of engineering time will make elegant.

Next step

One Mailgun account, predictable volume, no dedicated IP or validation add-ons: the control panel is enough, and the monthly click is not worth automating. Multi-tier plans with overages, dedicated IPs, extended log retention, validation batches, or a Sinch billing migration in progress: connect Mailgun to Inbox Ledger once and let the PDFs flow into your accounting system with every line item already parsed.

Where to look in the dashboard

Account then Billing is the main billing hub, with current plan, payment method, and invoice history in one place
Account then Billing then Invoices (or Billing History) is where PDFs live, one per monthly cycle
Account then Billing then Alerts is where you set spend notifications for overage protection
Account then Account Settings is where the legal entity name, billing address, and VAT ID are stored
Logs and Analytics let you reconcile invoice volume against what was actually sent during the period
Validations (under Sending) has its own usage counter that feeds into the same monthly invoice

Before you start — quick checklist

Your legal entity name and billing address match what is on record in Account Settings
VAT or tax ID is printed if required in your country, especially for EU and UK accounts billed by Sinch AB
The plan fee line matches the tier you are actually subscribed to (Foundation, Growth, Scale, or Flex pay-as-you-go)
Overage charges for messages above the plan-included volume are itemized and match what your Analytics dashboard shows for the period
Dedicated IP add-ons, extended log retention, and email validation purchases appear as separate line items, not bundled into a generic usage figure
The document is a finalized invoice PDF with an invoice number, not a mid-cycle usage estimate or balance summary

Pro tips

Mailgun's plan fee and message overage are two different numbers on the same invoice. The plan fee is predictable every month. The overage scales with volume and is where most surprise charges come from. Check both lines before signing off.
A dedicated IP is a flat monthly add-on on top of your plan. Teams running transactional email on a shared IP and then adding a dedicated IP for deliverability often forget to account for this line, and the first invoice after the change looks wrong. It is not wrong, it just now includes an extra fixed fee per dedicated IP.
Log retention tiers (1 day, 5 days, 30 days depending on plan) are included up to a limit, but extended retention beyond the plan default is a separately billed add-on. If your compliance policy requires 90 days of logs, expect a line item for it.
Email validation through Mailgun Validations is metered per validated address, not per email sent. A one-off cleanup of a large list can create a large standalone charge in the same month as your normal sending, and both will appear on the same invoice. Budget for validation separately.
Viral sign-up spikes can push a low-traffic account over its plan volume in hours. Set a spend alert in Account then Billing then Alerts so you get a notification when usage crosses a threshold you choose. It will not cap sending, but it will tell you before the invoice does.
Mailgun is owned by Sinch since 2021. Accounts provisioned after the integration are billed through Sinch AB (Sweden), which affects VAT handling for European customers. Older accounts may still be billed by Mailgun Technologies, Inc. in Texas. Your bookkeeper may need to track both as separate vendors during the transition period.
