MailerLite to PostgreSQL Integration

How Datrise loads MailerLite into PostgreSQL

Datrise syncs MailerLite's subscribers, groups, campaigns, automations, email events, and forms into PostgreSQL as a typed table per source entity. Flexible or custom fields land in jsonb columns, and timestamps such as created, updated, and status changes are typed as timestamptz.

Sync is incremental: Datrise uses a watermark on each entity's updated-at, applied with INSERT … ON CONFLICT DO UPDATE, so re-runs update only what changed. Optional declarative range partitioning by load date for high-volume tables. PostgreSQL folds unquoted identifiers to lowercase, so Datrise normalizes mixed-case source fields to snake_case.

Ideal for operational analytics and application backends that need fresh, queryable copies of your data.

Endpoints

MailerLite: Email campaigns, automations, and landing pages.

PostgreSQL: Open-source relational database with strong SQL and extensions.

How MailerLite entities map to PostgreSQL

MailerLite entity	PostgreSQL object	Notes
subscribers	`mailerlite_subscribers`	id PK · custom fields → jsonb columns
groups	`mailerlite_groups`	id PK · linked to mailerlite_subscribers
campaigns	`mailerlite_campaigns`	id PK · linked to mailerlite_subscribers
automations	`mailerlite_automations`	id PK · linked to mailerlite_subscribers

FAQ

How does Datrise handle MailerLite's custom fields in PostgreSQL?

Flexible values are stored as jsonb columns, so new fields don't require a migration; strongly-typed fields — dates, numbers, and references — are promoted to native PostgreSQL types.

How does the MailerLite to PostgreSQL sync stay up to date?

It runs incrementally — Datrise uses a watermark on each entity's updated-at, applied with INSERT … ON CONFLICT DO UPDATE.
