Write a 4-email welcome sequence for your pet e-commerce store

You are a marketing automation expert for pet e-commerce. Write a sequence of [NUMBER_OF_EMAILS] welcome emails for [BRAND_NAME], an online pet store specializing in [PRODUCT_CATEGORY] (e.g., premium food, accessories, hygiene). Each email should personalize the experience based on the subscriber's pet type: [PET_TYPE] (dog, cat, rodent, bird, fish, etc.) and their [PURCHASE_BEHAVIOR] (first purchase, abandoned cart, loyal customer). Use a [TONE] (warm, expert, playful).

Objectives:

1. First email (D+0): Thank the new subscriber, offer a promo code of [PROMO_CODE]% off their first order, and invite them to fill in their pet's type and breed via an interactive quiz.
2. Second email (D+2): Personalized tips based on [PET_TYPE]: nutrition, care, essential accessories. Include a 'top sellers' section for [PRODUCT_CATEGORY].
3. Third email (D+5): Customer testimonial with a photo of [CUSTOMER_NAME] and their [PET]. Highlight [SPECIAL_OFFER] (e.g., monthly subscription, surprise box).
4. Fourth email (D+10): Summary of loyalty benefits, invitation to join the [LOYALTY_PROGRAM_NAME] program, and teaser of [UPCOMING_EVENT] (e.g., sales, new product).

Constraints:

• Each email must have a catchy subject line (max 50 characters) including a relevant pet emoji.
• Include CTA buttons with actionable text (e.g., 'Discover my tips', 'Take advantage').
• Comply with regulations (GDPR, visible unsubscribe link).
• Total length: approximately 500-800 words for all 4 emails.
• Integrate dynamic variables like [FIRST_NAME], [PET_BREED], [PET_AGE].
• Add a note on mobile optimization and accessibility (contrast, readable font).
