Automatic series of emails for a multilingual online store

For a multilingual niche perfume online store, I have created automatic series of emails: welcoming new subscribers, motivation after the first order, reminder of abandoned cart.
In the list of tasks:
Texts for 14 emails.
Unique design.
Assembly of email templates.
User segmentation by events and language localization.
Setting up automatic email sending based on events.
In just the first three months of work, the sales chains from these emails generated several hundred thousand euros!
