MailerLite + Memtro

Campaign results, group health and who opened what, straight from MailerLite.

Connect MailerLite with an API token and Memtro reads subscribers with their fields and engagement, groups with counts and rates, campaigns with opens, clicks, unsubscribes and bounces and who opened or clicked, sign-up forms and automations. It reads on demand and there is no hourly sync. When asked, and once an administrator has granted each action by name, it can add, update and delete subscribers, manage groups and custom fields, and draft, schedule or send campaigns. Sending emails the whole audience outside the company and cannot be undone, and forgetting a subscriber erases them permanently after 30 days.

In Memtro

What you can do with MailerLite in Memtro

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

What it does

  1. 01The account at a glance: total subscribers, the largest groups, the latest sent campaigns and automations running
  2. 02A subscriber by email with status, source, groups and emails sent, opened and clicked with rates
  3. 03Campaigns newest first with sent, unique opens, clicks, unsubscribes, spam reports and bounces, and who opened or clicked one
  4. 04Groups with active, unsubscribed, unconfirmed, bounced and junk counts, sign-up forms with conversions, and automations with who entered or completed
  5. 05When asked and granted, adds, updates or deletes subscribers, moves them between groups and creates, renames or permanently deletes groups and custom fields. Joining a group can start an automation that emails them
  6. 06When asked and granted, drafts and edits campaigns, then sends one now or schedules it, emailing everyone in its groups. Sending now cannot be undone, and deleting a campaign removes its report permanently

Acts when asked

When you ask it to

These tools change something in MailerLite. 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. 01Add a subscriber, or update the one with that email, optionally into groups
  2. 02Update a subscriber's fields, status or full set of groups
  3. 03Delete a subscriber (their data is kept in case they resubscribe)
  4. 04Forget a subscriber under GDPR, erased permanently after 30 days
  5. 05Create a group
  6. 06Rename a group
  7. 07Delete a group permanently
  8. 08Add a subscriber to a group
  9. 09Remove a subscriber from a group
  10. 10Draft a regular email campaign
  11. 11Edit a draft campaign
  12. 12Send a campaign now or schedule it, emailing its whole audience
  13. 13Cancel a scheduled campaign back to draft
  14. 14Delete a campaign permanently
  15. 15Create a custom subscriber field

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 MailerLite for you. Each event can start a job, with the event as its input. MailerLite 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 MailerLite 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.

MailerLite logoMailerLite + Memtro
  • How did the 'Autumn offers' campaign do, and who clicked?

  • Which groups have the highest open rate, and which has the most bounces?

  • Is tom.ashby@example.co.uk subscribed, which groups is he in, and does he open anything?

  • Is the welcome automation still running and how many people are queued in it?

  • Add jane.cole@northwind.example to the Webinar group

01

Who clicked

The marketing lead asks who clicked in Tuesday's campaign. Memtro returns the campaign's stats, then the subscribers who clicked with their opens and clicks, so sales can follow up the ones who are already customers.

02

Scheduling the newsletter

Priya Shah asks Memtro to send the approved November newsletter draft to the Customers group at 9am on Thursday. Memtro reads the campaign, checks its subject and groups, and schedules it in MailerLite. It stays cancellable back to draft until it starts, and then emails every subscriber in the group.

Teams

Where it fits

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

Better together

Works with

A record in MailerLite 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 Marketing automation

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 withAPI token
  1. 1

    In MailerLite open Integrations → MailerLite API → Generate new token, name it and copy the token: it is shown once

  2. 2

    This is for the current MailerLite at dashboard.mailerlite.com. A token from MailerLite Classic uses a different API and will not work

  3. 3

    In Memtro open Connections → MailerLite, paste the API token and connect. MailerLite allows 120 requests a minute per token

  4. 4

    Ask how the last campaign did or who clicked it

Also works from

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

FAQ

Questions

Can Memtro change anything in MailerLite?+

Only when you ask, and only what it has been granted: add a subscriber, or update the one with that email, optionally into groups; update a subscriber's fields, status or full set of groups; delete a subscriber (their data is kept in case they resubscribe); forget a subscriber under GDPR, erased permanently after 30 days; create a group; rename a group; delete a group permanently; add a subscriber to a group; remove a subscriber from a group; draft a regular email campaign; edit a draft campaign; send a campaign now or schedule it, emailing its whole audience; cancel a scheduled campaign back to draft; delete a campaign permanently; create a custom subscriber field. 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 MailerLite 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 MailerLite 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 MailerLite?+

API token. In MailerLite open Integrations → MailerLite API → Generate new token, name it and copy the token: it is shown once.

Can MailerLite 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 MailerLite 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.
