MailerLite WooCommerce POS — Oliver POS Integration Guide

Oliver POS doesn't have a partnership with MailerLite. It supports MailerLite because MailerLite ships an official WooCommerce sign-up plugin that already syncs subscribers and orders from WooCommerce into MailerLite. Oliver writes every in-store sale into WooCommerce as a normal order, the plugin treats it the same way it treats an online order, and every newsletter, workflow, and e-commerce report picks up counter customers. MailerLite does the email. WooCommerce is the system of record. Oliver is the till on top.

What MailerLite is, exactly

MailerLite is a clean, affordable email-marketing platform popular with small businesses worldwide. Its appeal is simplicity at low cost — generous free tiers, a friendly drag-and-drop editor, and segmentation that's enough for SMB use cases without being overwhelming. The platform is widely used by independent retailers and solo entrepreneurs who want professional email without enterprise complexity.

The MailerLite Sign-Up Forms for WooCommerce plugin adds sign-up forms to WordPress and connects WooCommerce checkout opt-ins to MailerLite subscriber groups. Order data flows in via the e-commerce integration, populating MailerLite's segmentation and workflow conditions.

How Oliver POS feeds in-store sales into MailerLite

The MailerLite WooCommerce POS flow inside Oliver:

1. The cashier rings the sale on the Oliver register and taps Charge.
2. Oliver prompts to attach a customer with email + marketing consent.
3. The cashier takes payment through whatever WooCommerce payment gateway the store uses.
4. Oliver writes a standard WooCommerce order.
5. The MailerLite plugin syncs the subscriber and the order into MailerLite.
6. Automations triggered by "subscriber added to group" or "order placed" fire on the in-store sale the same way they would on an online sale.

The MailerLite WooCommerce plugin — what Oliver rides on

Oliver rides on the official MailerLite plugin. Setup mirrors any other MailerLite onboarding: install the plugin, paste your MailerLite API key, pick the group, and let sync handle the rest.

Why pushing in-store sales into MailerLite matters

For a single-location retailer, simplicity at low cost often means the marketing team is one person who needs every contact and every purchase in one place to make decisions. Oliver POS closes the loop by pushing counter sales through WooCommerce into MailerLite, so the segmentation reflects the whole business and the e-commerce dashboard tells the full revenue story.

What this is NOT

Oliver POS is not a MailerLite partner. There's no co-marketing agreement, no revenue share, and no special pricing. Oliver doesn't insert itself between WooCommerce and MailerLite; the data path is the same one any WooCommerce store uses. Oliver doesn't charge a markup or per-contact fee. Your MailerLite account is entirely between you and MailerLite.

Setup in 4 steps

1. Install the official MailerLite plugin and connect to your MailerLite account using your API key.
2. Pick the subscriber group to receive WooCommerce customers and verify the initial sync completes.
3. Install Oliver POS, sign in to the register, and confirm the customer-capture prompt with marketing consent is enabled at checkout.
4. Run a small live test sale at the counter and confirm the subscriber and order appear in MailerLite within seconds.
