MailerSend + Memtro

Did our password reset email reach the customer, and if not, why?

MailerSend connects Memtro to your transactional email. It reads the account's plan, quota and limits, sending domains with their DNS status, and the sending log for a domain with sender, recipient, subject, status, opens and clicks, and why an email was rejected. It also reads one email's delivery events, templates and scheduled messages. When asked, and once an administrator has granted the action by name, it can send an email, which reaches real people, cancel a scheduled one, manage templates and add addresses to a suppression list. Message bodies are never returned.

In Memtro

What you can do with MailerSend in Memtro

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

What it does

  1. 01Shows the account's plan, emails sent this cycle against the limit, and its rate limits
  2. 02Lists sending domains with whether verified, DKIM and SPF status, whether sending is paused and totals sent, delivered and rejected
  3. 03Reads a domain's sending log over a date window with sender, recipient, subject, status, opens, clicks and why an email was rejected, and one email's delivery events
  4. 04Lists templates and scheduled messages with when each is due to send
  5. 05When asked and granted, sends an email from a verified domain, now or up to 72 hours ahead, which reaches real people and counts against the plan's quota, or cancels a scheduled one
  6. 06When asked and granted, creates, edits or permanently deletes a template, and adds addresses to a suppression list so MailerSend stops sending to them

Acts when asked

When you ask it to

These tools change something in MailerSend. 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 (billed against the plan, reaches real people)
  2. 02Cancel a scheduled email
  3. 03Create an email template
  4. 04Edit an email template
  5. 05Delete an email template
  6. 06Add addresses to a suppression list (they stop receiving mail)

Events

When it happens

Turn events on in the connection's Events tab on the Connections page, choose the kinds you want, and Memtro registers its address with MailerSend for you. Each event can start a job, with the event as its input. MailerSend signs every delivery, and one whose signature does not check out is refused before it is read.

In practice

Ask it like you would a colleague

Once MailerSend 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.

MailerSend logoMailerSend + Memtro
  • Did the password reset email to priya@acme.example arrive?

  • Why were emails rejected on our domain yesterday?

  • How many emails have we sent this cycle against our limit?

  • Is our sending domain's DKIM verified?

  • Add bounced@bigco.example to the blocklist

01

A missing receipt

Tom Reilly, support lead at Acme Ltd, asked whether a customer's receipt email had been delivered. Memtro found the email in the sending log and listed its delivery events, which showed a hard bounce, with the reason MailerSend gave.

02

Stopping a bad address

Maya Okafor, product engineer at Northwind, asked Memtro to stop sending to an address that kept bouncing. Memtro added it to the hard bounces suppression list in MailerSend, so later emails to it are not sent. Removing it again has to be done in MailerSend.

Teams

Where it fits

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

Better together

Works with

A record in MailerSend 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.

How to connect

Connect withAPI token

FAQ

Questions

Can Memtro change anything in MailerSend?+

Only when you ask, and only what it has been granted: send an email (billed against the plan, reaches real people); cancel a scheduled email; create an email template; edit an email template; delete an email template; add addresses to a suppression list (they stop receiving mail). 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 MailerSend 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 MailerSend 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.

How do I connect MailerSend?+

API token. In MailerSend, open Integrations → API tokens → Generate new token, name it Memtro and choose the domain.

Can MailerSend start a job?+

Yes. Turn events on in the connection's Events tab on the Connections page, choose the kinds you want, and Memtro registers its address with MailerSend for you. 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.
