Work in MailerLite with AI, safely

Connects your AI assistant to MailerLite and works out which account and scope you mean before reading or changing anything. It asks for your explicit yes before any step that edits, sends, schedules or deletes.

Use it when

You connect MailerLite to an assistant for the first time
You want help with subscribers or groups and need the changes made carefully
You are not sure which MailerLite tool fits your request

Tools it uses

get_subscriber
add_subscriber
update_subscriber
delete_subscriber
forget_subscriber
list_subscribers
get_subscriber_count
assign_subscriber_to_group
unassign_subscriber_from_group
get_group_subscribers
get_campaign_subscribers
create_group
update_group
delete_group
create_campaign
update_campaign
delete_campaign
schedule_campaign
cancel_campaign

Example

Count the bounced subscribers in my main account, then tell me what would change if we removed them. Don't delete anything yet.

Your main account has 1,284 bounced subscribers. Removing them would delete 1,284 records; deleted subscribers keep their history, so they can re-subscribe later. I haven't changed anything. Tell me which action you want and I'll confirm the exact scope before running it.

Review a sent MailerLite campaign with AI

Reads a sent campaign's recipients and link clicks and reports engagement honestly, separating real signal from small samples. It only reads data and recommends next steps, and asks before changing anything.

Use it when

A campaign went out and you want to know how it did
You need to see which links got clicked and by whom
You want to decide what to change in the next send

Tools it uses

get_campaign
list_campaigns
get_campaign_subscribers

Example

How did our spring newsletter campaign do, and what should we change for the next one?

The spring newsletter went to 1,240 recipients and 186 of them clicked a link, a 15% click rate. The main call-to-action link drew 142 of those clicks, and most came from the webinar signup group. Unsubscribes were 9 (0.7%), which is in line with your list. Recipients are still arriving, so this may rise. I would test a clearer call to action in the next send, and I have not changed anything yet.

Check a MailerLite campaign before it sends

Checks a draft campaign's recipients, sender, subject and content before it is scheduled, and reports what a schedule or cancel would change. It asks before scheduling, cancelling or editing anything.

Use it when

Before scheduling a campaign for a big list
When you need to know exactly who a campaign will reach
When a draft has been edited and you want a final check

Tools it uses

get_campaign
get_campaign_subscribers
get_group_subscribers
get_subscriber_count
schedule_campaign
cancel_campaign
update_campaign

Example

Audit my draft 'Spring offer' campaign before I schedule it for Friday morning.

Campaign 'Spring offer' is a draft with 2,380 verified recipients from the 'Newsletter' group. The sender and subject are set, but one A/B variant has an empty subject line and the footer has no unsubscribe link. Blocking: fix the empty variant and add the unsubscribe before scheduling. I have not changed anything. Shall I make those edits?

Audit MailerLite groups and segments with AI

Maps your MailerLite groups and segments, finds overlapping or empty ones, and checks who a campaign would actually reach. It proposes changes and asks before changing any membership.

Use it when

You suspect duplicate or unused groups and want them mapped before tidying
A campaign audience looks larger or smaller than expected
You want to know who a segment really includes after unsubscribes and bounces

Tools it uses

list_groups
get_group_subscribers
assign_subscriber_to_group
unassign_subscriber_from_group
delete_group

Example

Audit my MailerLite groups and segments and tell me which ones overlap or are empty, and how many people the Spring Launch segment would actually reach.

I found 14 groups and 6 segments. The 'Newsletter' and 'Newsletter list' groups overlap by 92%, so they look like duplicates. 'Old Promo 2022' has no members. The Spring Launch segment matches 3,410 subscribers, but only 2,870 would receive it after unsubscribed and bounced contacts are excluded. I have not changed anything; merging the duplicates would need your yes.

Clean up your MailerLite subscriber list with AI

Finds stale, unconfirmed, bounced and junk subscribers, sorts them into buckets and proposes what to remove or re-engage. It asks before deleting or moving anyone.

Use it when

Before a big send, to remove dead addresses that hurt deliverability
After a import brought in old or unconfirmed contacts
When bounce or junk counts have climbed and you want a plan

Tools it uses

get_subscriber_count
list_subscribers
get_subscriber
get_subscriber_activity
forget_subscriber
delete_subscriber
assign_subscriber_to_group
unassign_subscriber_from_group

Example

Clean up my MailerLite list. Find the bounced and long-unconfirmed subscribers and tell me what you would remove before doing anything.

Your list has 12,400 subscribers: 11,200 active, 600 unsubscribed, 340 unconfirmed, 180 bounced and 80 junk, with 0 left over. I would propose deleting 150 hard-bounced and 290 long-dormant unconfirmed records, keeping all 600 unsubscribed contacts, and moving 410 active-but-silent subscribers into a re-engagement group. Nothing has changed yet. Tell me which buckets you approve.

How MailerLite skills work

Connect MailerLite
The MailerLite MCP server gives the agent its tools.
Ask in plain words
“How did our spring newsletter campaign do, and what should we change for the next one?” Each SKILL.md says when it applies, so only the one that fits is loaded.
Approve any change
The agent calls the tools in order, checks its work, and shows you any change before it makes it.

How to install MailerLite skills

In RevampKey the skills install themselves when you connect MailerLite. In other tools each skill is one folder with a SKILL.md file, and you also need the MailerLite MCP server connected there.

MailerLite skills FAQ

What is a MailerLite agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each MailerLite skill describes one job, which MailerLite tools to use in which order, what to check first and when to stop and ask you.

Do the MailerLite skills change anything on their own?

1 of the 5 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in MailerLite.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect MailerLite; elsewhere you copy the folders into your project or skills directory.

Do I need the MailerLite MCP server too?

Yes. The skills tell the agent how to do the work; the MailerLite MCP server gives it the tools to do it. The MailerLite MCP setup guide covers every client.
