Automatically purify your MailerLite lists with AI

Swiftask analyzes your MailerLite subscribers, detecting inactive or invalid addresses. Keep your list healthy and high-performing without manual effort.

Result:

Drastically improve your open rates and protect your sender reputation in the long run.

Cluttered MailerLite lists hurt your campaigns

Sending emails to inactive or non-existent contacts damages your sender reputation. ISPs flag these sends as spam, reducing the deliverability of your important messages.

Main negative impacts:

  • Plummeting open rates: The more inactive subscribers you have, the lower your stats, penalizing your campaigns with actually engaged customers.
  • Blacklist risk: High bounce rates alert ISPs, increasing the risk that your legitimate emails go straight to the junk folder.
  • Wasted marketing costs: You pay to store and send emails to contacts who never convert, wasting your marketing budget.

Swiftask automates your MailerLite database cleaning. The AI agent identifies low-engagement segments, verifies email validity, and performs sorting based on your business rules.

BEFORE / AFTER

What changes with Swiftask

Manual MailerLite management

You export your lists periodically, check open stats one by one, and manually delete inactive users. It's tedious, slow, and often overlooked.

Intelligent Swiftask cleaning

Your AI agent monitors continuously. It detects inactive users based on your criteria and cleans your MailerLite database automatically. Your list is always fresh.

Deploy your cleaning agent in 4 phases

STEP 1 : Configure your agent

Create your agent in Swiftask and define inactivity criteria (e.g., no clicks in 6 months).

STEP 2 : Secure MailerLite connection

Connect your MailerLite account via API to allow the agent to read and manage your subscriber lists.

STEP 3 : Define exclusion rules

Set actions: permanent deletion, unsubscribe, or move to a re-engagement list.

STEP 4 : Execution and monitoring

The agent runs in the background. Track cleaning actions directly in your Swiftask dashboard.
