MailerLite integrations: direct apps and connector apps

Setup guides for specific apps

Each guide says whether the connection is built in or needs a connector, lists the events you can use and gives the setup steps.

• MailerLite and Airtable: There is no native MailerLite to Airtable sync. You connect them through a third-party tool such as Zapier or Make, one direction per workflow.
• MailerLite and Google Sheets: MailerLite connects to Google Sheets only through third-party connectors. Decide the direction first: rows into subscribers, or subscriber events into rows.
• Mailchimp to MailerLite import: The Mailchimp link is a one-way importer, not a live sync. It moves subscribers, tags, custom fields and simple segments; you rebuild templates, automations, forms and landing pages.
• MailerLite and Teachable: MailerLite's directory has no Teachable entry, but Teachable documents a MailerLite app in its App Hub on every plan that sends students one way into MailerLite groups; a connector such as Zapier is the other route.
• MailerLite and MemberVault: MemberVault has a direct MailerLite connection built by MemberVault. It sends subscriber and purchaser information one way, from MemberVault into MailerLite.
• MailerLite and Leadpages: Leadpages connects to MailerLite directly through its automations feature using an API token. It adds or updates subscribers and groups, but does not support tags.

Connecting Airtable or Google Sheets to MailerLite

MailerLite's official Airtable listing and Google Sheets listing point to third-party connectors, including Zapier and Make. Start with the connector's exact trigger and action, not just the presence of both app logos. A listing does not establish two-way sync, instant updates or support for every subscriber status.

Choose direction before choosing a connector

For Airtable → MailerLite, define which approved record is eligible to become a subscriber and what group it belongs to. For MailerLite → Airtable, decide whether you need subscriber records, campaign reporting or both. Those are separate workflows; an available action in one direction does not prove the reverse exists.

For Google Sheets → MailerLite, decide whether a new row, an edited row or a reviewed status should trigger the workflow. For MailerLite → Google Sheets, identify the row to update rather than appending a fresh row for every change. Verify the selected connector's present support for that event before committing to it.

Use these cases to accept or reject the workflow

1. Same record twice: replay one authorized test record. Expect the intended update, not a duplicate subscriber or duplicate downstream action.
2. Changed email or empty field: confirm which record changes and that unrelated data is not erased.
3. Unsubscribed contact: confirm an ordinary source edit does not silently restore marketing eligibility. If the connector cannot preserve the required suppression rule, stop that workflow.
4. Connector outage: establish where failures are visible, who receives an alert and how a recovery run avoids duplicate actions. Do not assume automatic retries are harmless.

Use authorized test records in a controlled setup, without sending campaigns or exposing real contact data. Write the expected result before the test, then record the actual result and time.

When a simpler route is better

A one-off, reviewed import may suit an occasional transfer better than an always-on sync. Frequent updates with important suppression or deletion requirements need a supported connector or a maintained custom integration—not an unattended spreadsheet workaround. Check connector fees, task limits, update delay and support ownership separately from MailerLite's subscription.

MailerLite's integration documentation distinguishes its native integrations from third-party integrations; help with a third-party connection comes from that integration's developer. Confirm that the connector targets your MailerLite version, especially if you still use Classic.

Connection-route sources reviewed September 28, 2026. The Airtable source was available through an indexed official-page extract after the direct page returned a rate-limit error; recheck its current connector list before setup.

How MailerLite integrations should work together

MailerLite describes its directory as more than 100 integrations: some are built and supported by MailerLite, such as Shopify, WooCommerce, Stripe and Zapier, while others, such as Make and MemberVault, are supported by their own developers. List every source that can create or update a subscriber: website, store, checkout, CRM, booking tool, webinar, spreadsheet, API, or manual action. For each field and event, name the authoritative system and allowed direction.

Setup guides for each app: Airtable, Google Sheets, Google Forms, Stripe, WooCommerce, Shopify, Teachable, MemberVault, Leadpages and the Mailchimp importer.

This prevents two-way sync loops, stale overwrites, and conflicting consent state. It also clarifies whether a native integration, automation connector, webhook, API, or scheduled import is appropriate. For every connection, document the source event, destination field, expected delay, retry behavior, and manual recovery step so a quiet sync failure does not become invisible customer drift.

Data and configuration requirements

Confirm supported objects, fields, events, filters, historical sync, update timing, duplicate handling, and error visibility. Test empty values, changed email addresses, unsubscribes, deletions, refunds, and records that fail validation.

An integration can be official and still omit a business-critical event. Document that gap and decide whether a manual process is acceptable before building automations that depend on it.

Protect consent and minimization

Move only the data required for a defined purpose. Preserve consent source and date where needed, honor suppression and deletion, and avoid placing sensitive information into tags, URLs, or systems that do not need it. Review the privacy and processing agreements applicable to the stack.

When several tools can send messages, define which system owns marketing preference and how changes propagate. A delayed unsubscribe sync is both a customer-experience and compliance risk.

Monitor integrations after launch

Create one synthetic or controlled record for recurring verification. Alert on failures, missing events, unusual volume, duplicate creation, or growing latency. Annotate connector, website, checkout, and schema changes.

Keep a fallback for critical workflows and record the last known-good payload. Integration reliability is part of the platform’s operating cost and should be reviewed alongside subscription price. A connection can be tried during MailerLite's 14-day premium trial, which asks for no payment method.
