Context
Part of a long engagement on tintadlaplastykow.pl (custom CMS, 36k+ SKU, since 2022) — this thread: marketing and analytics. Without automated reviews, reliable transactional email and GA4 e-commerce events, campaigns were hard to judge and product cards lacked social proof. API integrations built on Symfony HttpClient.
Scope
- TrustMate reviews — post-purchase invitations and ratings on product cards (API via Symfony HttpClient).
- Email and newsletter — MailerLite (segmentation) and MailerSend (transactional via API).
- GA4 e-commerce —
view_item,add_to_cart,purchaseevents (gtag.js) for purchase-path measurement.
Result
- After purchase, review invites go out; transactional emails arrive, and GA4 shows the real cart path.
- Custom CMS integrations — TrustMate, MailerLite/MailerSend, GA4 e-commerce events via Symfony HttpClient.
