Where can I find my Postmark invoices?

Invoices live under Account then Billing in the Postmark dashboard at account.postmarkapp.com/billing. The Invoices tab inside that page lists every monthly invoice with its date, amount, volume tier, and status, and each row has a download link for the PDF. There is no separate billing portal outside the dashboard. The Account Owner role is required to see the Billing section at all, so a developer invited only to a specific Server will not find it.

Does Postmark email invoices to the billing contact automatically?

Yes. Postmark sends an invoice notification by email to the billing contact on the Account after each successful monthly charge, with a link back to the dashboard where the PDF lives. If the wrong person is receiving those emails, the fix is to update the billing contact in Account Settings rather than change the login email, because the two are separate fields. Adding the accountant as an extra billing contact so a copy lands directly in their inbox is supported on current plans.

What is a Postmark Server and why does it matter for billing?

A Server in Postmark is an isolated sandbox for one application. It has its own API tokens, its own sending streams (transactional and broadcast), its own templates, and its own message history. What it does not have is its own billing. Every Server on an Account draws from the same shared monthly email pool, and every Server appears on the same invoice as part of that combined count. Teams running one Postmark account for multiple apps sometimes expect per-Server invoicing and are mildly surprised when the first bill rolls everything into one number. The practical answer is either to use one Account per customer or per cost center, or to accept the unified invoice and reconcile internally from the Activity logs.

How does Postmark's volume-based pricing work on the invoice?

Postmark prices monthly plans by email volume, with tiers at 10K, 50K, 100K, 300K, 700K, 1.5M, 3M, and upward. The plan fee is fixed for the tier you select. If you send above the tier in a given month, Postmark charges per-email overage at a published rate rather than auto-upgrading the plan. Both the plan fee line and any overage line appear on the same monthly invoice as separate items. The invoice PDF shows the tier name, the emails included in the tier, the actual emails sent, and the overage count if any.

How does VAT work on Postmark invoices after the ActiveCampaign acquisition?

Postmark is now billed by ActiveCampaign, LLC, a US entity headquartered in Chicago. US customers are charged applicable US sales tax where required, with no VAT. EU and UK business customers who provide a valid VAT ID in Account Settings receive a reverse-charge invoice with no VAT added, which is correct under standard EU rules for US-supplied digital services. EU consumers without a VAT ID may have VAT collected under the OSS or MOSS scheme depending on jurisdiction. Past invoices cannot be rewritten with a new VAT ID, so add yours in Account Settings before the next charge.

Why does my Postmark invoice say ActiveCampaign instead of Wildbit or Postmark?

ActiveCampaign acquired Wildbit, Postmark's parent company, in 2022. Invoices issued before the acquisition reference Wildbit, LLC as the seller. Invoices issued after the billing migration reference ActiveCampaign, LLC, with Postmark listed as the product on the line item. Both sets of PDFs are valid accounting documents for the same underlying service. Your accounts payable system may treat the two as separate vendors for audit purposes, and most finance teams keep the Wildbit record open until the last pre-migration invoice has aged past the retention window, then retire it.

Can I pay for Postmark annually instead of monthly?

Postmark offers annual billing on request, typically with a modest discount compared to paying month-to-month on the same tier. Annual billing generates one invoice upfront covering twelve months, rather than twelve separate PDFs. Switching an existing monthly account to annual mid-cycle usually produces a credit note for the unused monthly portion plus the new annual invoice on the same day. The self-serve dashboard is oriented toward monthly plans, so the annual switch is most commonly handled through a support ticket rather than a click in the UI.

How can I avoid surprise Postmark overage charges?

The best lever is picking the right tier rather than waiting for overage to trigger. Postmark shows your running monthly email count prominently on the Billing page and the main dashboard, and it exposes a webhook plus API for programmatic volume tracking. For teams with variable traffic, the cleanest pattern is a simple internal alert on sent volume against the current tier, which fires before the tier ceiling and gives you a chance to upgrade before overage rates apply. Postmark does not cap sending automatically, so the invoice will still land if you ignore the warning.

Can my accountant see Postmark invoices without full sending access?

Postmark supports user roles under Account then Users, but billing access is tied to the Account Owner role rather than a dedicated billing-only role. The practical options are either to transfer ownership (not usually what you want), to invite the accountant as an Account Owner and accept that they can see sending too, or to forward the PDFs through an automation layer. Most Postmark customers go with the forwarding approach because the product is opinionated about who owns the Account, and Owner is not a role most finance teams need at the sending level.

How long does Postmark keep old invoices available?

Invoices are visible in the Billing section for the life of the Account. Postmark has historically retained billing history across ownership changes, including the ActiveCampaign migration, which is a stronger signal than most SaaS vendors offer. That said, retention is a matter of vendor policy and not a contractual guarantee beyond the standard accounting window. For tax and audit purposes, keep your own copies in an accounting system with multi-year retention. A cancelled Account can lose access to the Billing tab, which is the worst possible moment to realize you never downloaded the PDFs.

Can I pull Postmark invoice PDFs through the API?

Postmark's API is rich for sending, message events, templates, activity stats, and inbound processing, but it does not expose invoice PDFs as a programmatic endpoint. You can reconcile volume and cost estimates in real time by pulling sent counts from the Stats API, which is how most engineering teams build their own budget dashboards. The actual invoice document, though, only exists through the dashboard download. Finance teams with a year of Postmark history to capture either click through each PDF by hand or connect the Account to a tool that captures the invoice emails as they arrive.

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

Start by opening the invoice PDF and identifying the plan fee line. Confirm the tier matches what you signed up for. Then check the overage line against the Activity view on each Server for the same period. Next, look for a dedicated IP line item that may have been added by a teammate, or an inbound processing line if a Server started parsing replies mid-month. If all of those match and the number still looks wrong, filter the Activity view by Tag or by Stream to see whether one particular flow (password resets, order confirmations, a notification service) is sending far more than it should. Most surprise Postmark bills trace to one specific misconfigured flow, which is visible in the logs once you know which tag to filter on.

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

Step-by-step: download invoices from Postmark

1
Sign in to the Postmark account
Go to account.postmarkapp.com and sign in with the email that owns the account. Postmark has two distinct layers worth knowing about. The first is the Account (the billing entity and the thing your credit card is attached to). The second is the Server (a sandbox for one application, with its own sending streams, templates, and message history). Billing sits at the Account level, so you do not need to pick a Server to find invoices. You do need a role that can see billing, which is the Account Owner role by default. Server Admins and developers invited to individual Servers cannot see the Billing tab at all.
2
Open Billing from the Account menu
Click your profile icon in the top-right of the Postmark dashboard, choose Account from the dropdown, and pick Billing in the left sidebar. The direct URL is account.postmarkapp.com/billing. This page shows your current monthly plan (tiered by email volume from 10K up through several million per month), the card on file, the next renewal date, and the running count of emails sent across every Server on the account. One Account can hold many Servers, but every Server draws from the same monthly email pool and appears on the same invoice.
3
Open Invoices and download each PDF
Inside Billing, click the Invoices tab. You see a table of monthly invoices with date, amount, plan volume, and status. Each row has a download link that produces the invoice PDF. Postmark issues one invoice per monthly billing cycle, with the plan fee and any overage for emails sent above the tier rolled into the same document. Dedicated IPs and inbound processing add-ons appear as separate line items on that same invoice rather than generating their own PDFs. Since the ActiveCampaign acquisition in 2022, newer invoices reference ActiveCampaign, LLC as the billing entity, with Postmark listed as the product. Older invoices still reference Wildbit, LLC and remain valid for bookkeeping.
4
File by month and cross-check against Server activity
Use a naming pattern such as date plus Postmark plus amount so files sort chronologically alongside your other transactional email vendors. For any month where the invoice jumps, open the Activity view on the affected Server and compare the sent count against the volume on the invoice. A single misconfigured retry loop, a bulk announcement sent from a Server sized for transactional traffic only, or a new Server added mid-month are the three things that push a Postmark bill over its tier without warning. All three are visible in the Activity view once you know to check.

About Postmark billing

Postmark is the transactional email service you pick because the sending side is clean and the logs are honest. The billing side is clean too, right up to the point where one Account has four Servers, a dedicated IP, inbound processing on one of them, and a volume tier that is suddenly one step too small.

The invoice rolls every one of those pieces into a single monthly PDF, which is tidy in theory and a reconciliation puzzle in practice whenever the number is bigger than finance expected.

The single most common Postmark billing surprise is forgetting that every Server on an Account shares the same monthly email pool. Add a fourth Server for a new internal tool, send a one-time announcement from it, and the combined count can push the whole Account into a higher tier or trigger overage rates on what used to be a predictable bill. The invoice does not break out volume per Server, so the reconciliation happens in the Activity logs.

About Postmark

Postmark is a transactional email service focused on developer experience, reliable delivery for high-stakes messages like password resets and order confirmations, and generous logging that finance and support teams both rely on. Founded by Wildbit in 2010 and headquartered in Philadelphia, the product was acquired by ActiveCampaign in 2022 and is now billed by ActiveCampaign, LLC out of Chicago. Pricing runs on monthly per-email-volume tiers, with add-ons for dedicated IPs and inbound message processing. Each Account holds one or more Servers (isolated sandboxes per application), and all Servers on the Account bill together on a single monthly invoice.

Why people stop doing this by hand

One Postmark Account on a flat 10K tier with a single Server and no add-ons is a clean monthly invoice. Click, download, file, done in under two minutes. The routine holds up for as long as your product stays in that shape.

The moment a second product goes live, a new Server gets created for it. The moment deliverability becomes a priority, a dedicated IP gets added. The moment support starts parsing replies automatically, inbound processing gets turned on. Each of those changes is a good engineering decision, and each one makes the invoice one line longer and the reconciliation one step more interesting. Finance teams working to a five-day close tend to find that the Postmark hunt alone eats twenty minutes a month once the Account reaches the third Server, mostly because cross-checking the combined volume back to individual Server Activity views is manual clicking.

The ActiveCampaign acquisition added one more wrinkle. Vendor records in accounts payable systems often still carry Wildbit, LLC from the pre-2022 period, and the migration to ActiveCampaign, LLC invoicing has to be reconciled before the old vendor can be retired.

The Postmark API gives you rich sending data, per-tag analytics, and detailed Activity logs. What the API does not give you is the invoice PDF itself, and that is the document finance actually needs. Most teams with more than one Server end up automating the capture side rather than clicking through the dashboard every month.

Next step

One Postmark Account, one Server, flat tier, no add-ons, predictable volume. The dashboard is enough, and the monthly routine is not worth automating.

Multiple Servers, dedicated IPs, inbound processing, occasional overage, or a Wildbit to ActiveCampaign vendor transition still in progress on the accounts payable side. Connect Postmark to Inbox Ledger once and let the invoices land where your accountant actually looks, with every line item already parsed.

Where to look in the dashboard

Account then Billing is the main billing hub with plan, payment method, and invoice history in one place
Account then Billing then Invoices is where PDFs live, one per monthly cycle
Account then Account Settings is where the legal entity name, billing address, and VAT ID are stored
Account then Users controls which teammates can see the Billing tab (Account Owner role only by default)
Servers then Activity on each Server shows message-level logs with generous retention, useful for reconciling invoice volume against actual traffic
Account then API Tokens is for programmatic access to sending and stats, but not to billing PDFs

Before you start — quick checklist

Your legal entity name and billing address match what is on record in Account Settings
Tax ID or VAT number is printed on the PDF if required in your country, especially for EU and UK customers
The plan fee line matches the volume tier you are subscribed to and is not a pro-rated mid-cycle change you did not expect
Overage charges for emails sent above the tier are itemized, not folded into an unlabeled total
Dedicated IP add-ons and inbound processing fees appear as separate line items on the same invoice
The seller on the PDF is ActiveCampaign, LLC for invoices issued after the 2022 acquisition, or Wildbit, LLC for older ones

Pro tips

Postmark's tier pricing steps up in chunks (10K, 50K, 100K, 300K, 700K emails per month and upward). If you cross a threshold with a week to spare, Postmark does not auto-upgrade mid-cycle. You pay per-email overage instead, which is usually more expensive than simply moving up a tier. Check the Billing page before the month closes if your volume is trending high.
Every Server on an Account shares the same monthly email pool. Finance teams sometimes assume each Server has its own plan and get surprised when the fourth Server pushes the combined count into a higher tier. The fix is to review Server count and per-Server volume quarterly, not to try to isolate billing per app.
Postmark is strict about transactional versus broadcast email. Sending marketing newsletters from a transactional Server can get the Server suspended, which also triggers an adjustment on the next invoice. If you need both streams, use the Broadcasts feature or a separate Server dedicated to broadcast traffic.
Inbound email processing (parsing replies into your app through Postmark's inbound stream) is billed separately per 10K processed messages. It appears on the same invoice but as its own line. Teams that use inbound for customer support tickets and for auto-reply detection sometimes pay for it twice without realizing, once for each use case sitting on the same Server.
Dedicated IPs are a flat monthly add-on for reputation isolation on high-volume accounts. The IP does not generate its own invoice. It shows as a single line on the monthly bill, separate from the plan fee. Cancelling an IP stops the charge at the end of the current cycle, not immediately, so expect one more bill to include it.
ActiveCampaign acquired Postmark's parent company Wildbit in 2022. Invoices issued after the migration reference ActiveCampaign, LLC (Chicago, Illinois) as the seller, with the Wildbit name retired. Your accounts payable records may need both vendors open during the transition quarter before retiring the older one.
