Postmark + Memtro

What happened to every transactional email your Postmark server sent.

Connect one Postmark server with its Server API token and Memtro finds a message by recipient, tag or subject and follows its delivery, open, click and bounce events, lists bounces, and reports sends, bounces, complaints, opens and clicks. The hourly sync remembers each finished day's totals. When asked, and once an administrator has granted each action by name, it sends emails, one at a time, from a template or up to 50 in a batch, delivered at once to the recipients outside the company and never recalled. It also reactivates bounced addresses and manages suppressions, templates and message streams.

In Memtro

What you can do with Postmark in Memtro

Ask in plain English from chat, your editor, a scheduled job or your own agent. The model picks the right Postmark tool, reads what it needs, and answers with the source cited.

What it does

  1. 01Find messages by recipient, sender, tag, status, subject or date, and read one message's body and its events in order
  2. 02Bounces by type, address or tag, with whether Postmark deactivated the address and can reactivate it
  3. 03Sends, bounce rate, complaints, opens and clicks for any range in the past year, per day or tag, and an hourly sync of each finished day's totals
  4. 04Templates, message streams and, with the account token, every server, domain and sender signature
  5. 05When asked and granted, sends an email, a template email or a batch of up to 50 from a confirmed sender. Each is delivered at once and cannot be recalled
  6. 06When asked and granted, reactivates a bounced address, suppresses or unsuppresses addresses on a stream, creates, edits or permanently deletes templates, creates or archives streams and retries failed inbound messages

Acts when asked

When you ask it to

These tools change something in Postmark. The model is told to use them only when you ask for exactly that, and an administrator grants each one by name to the teams that may use it; a personal connection acts only after its owner allows it.

  1. 01Send an email from a confirmed sender to the recipients given
  2. 02Send an email rendered from a template
  3. 03Send up to 50 separate emails in one batch
  4. 04Reactivate an address Postmark deactivated after a bounce
  5. 05Suppress addresses on a message stream, or lift their suppression
  6. 06Create, edit or delete a template
  7. 07Create a message stream, or archive one
  8. 08Retry a failed inbound message

Events

When it happens

Turn events on in the connection's Events tab on the Connections page, then add the address it shows as a webhook in Postmark, choosing the same kinds; the tab shows Postmark's own steps. Each event can start a job, with the event as its input. Postmark sends a secret with every delivery, and one without it is refused.

Events and webhooks

  • 02A message bounced

In practice

Ask it like you would a colleague

Once Postmark is connected, these are the kinds of things people ask. Plain questions, no syntax. If the answer lives partly in another system you have connected, Memtro looks there too.

Postmark + Memtro
  • Did the password reset to priya@northwind.co.uk on 3 November get delivered?

  • Which addresses hard-bounced this week and are now deactivated?

  • What were our bounce rate and spam complaint rate in October?

  • What happened to the receipt tagged order-confirmation sent to jo@acme.com yesterday?

  • Reactivate jo@acme.com now that their mailbox is fixed and resend the receipt

01

It never arrived

A customer says the receipt never came. Support asks Memtro, which finds the message by recipient, reads its events and reports a hard bounce at 09:14 with Postmark's description and that the address is now deactivated.

02

Back in the inbox

Joe Martin at Acme says his mailbox is fixed. Support asks Memtro to reactivate his address and resend the receipt. Memtro checks the bounce can be reactivated, reactivates it, then sends the receipt template to him from the confirmed sender, delivered at once.

Teams

Where it fits

The teams that lean on Postmark most, a question each of them asks, and what they connect beside it.

Better together

Works with

A record in Postmark is rarely the whole story. Connect the systems that hold the rest and Memtro checks them together, then remembers what it learned so the next question starts further along.

Also in Email, calendar and chat

Using something else for the same job, or both? Each connector has its own tools; connect as many as you like.

Setup

How to connect

Connect withServer API token
  1. 1

    In Postmark open Servers → the server → API Tokens and copy a Server API token. It reaches only that server's messages, bounces, statistics, templates and streams, and with it Memtro can send from that server once the actions are granted

  2. 2

    To see the account's servers, domains and sender signatures too, copy an Account API token from Account → API Tokens. Only the account owner and admins can see it

  3. 3

    In Memtro open Connections → Postmark, paste the Server API token (and the account token if you have one) and connect

  4. 4

    Ask what happened to the email a customer says never arrived

Also works from

Chat in the dashboard, the OpenAI-compatible API, scheduled jobs, and any MCP client: Claude Code, OpenCode, Cursor, Claude Desktop. The Postmark tools are the same everywhere.

FAQ

Questions

Can Memtro change anything in Postmark?+

Only when you ask, and only what it has been granted: send an email from a confirmed sender to the recipients given; send an email rendered from a template; send up to 50 separate emails in one batch; reactivate an address Postmark deactivated after a bounce; suppress addresses on a message stream, or lift their suppression; create, edit or delete a template; create a message stream, or archive one; retry a failed inbound message. Every other tool reads, searches or lists. The Connections page labels the tools that act, an administrator grants each one by name to the teams that may use it, and a personal connection acts only after its owner allows it.

Who can use a Postmark connection?+

A personal connection serves only your own requests. A shared connection serves the organisation: everyone, or only the teams an admin chooses. Admins can always add shared connections; other members need the permission.

Does Memtro store my Postmark data?+

Credentials are encrypted at rest. Tool results are cached briefly so agent loops do not repeat identical calls, and the facts the model extracts are saved to your organisation's memory with provenance (system, record and link) so they can be checked and superseded. An hourly sync anchors recently changed Postmark records into memory as entities.

How do I connect Postmark?+

Server API token. In Postmark open Servers → the server → API Tokens and copy a Server API token. It reaches only that server's messages, bounces, statistics, templates and streams, and with it Memtro can send from that server once the actions are granted.

Can Postmark start a job?+

Yes. Turn events on in the connection's Events tab on the Connections page, then add the address it shows as a webhook in Postmark, choosing the same kinds; the tab shows Postmark's own steps. A job set to start "When an event arrives" then runs once for each matching event, with the event as its input. The run treats the event as outside data, never as instructions, and anything the run remembers is kept as unverified.
