What discount email frequency prevents subscriber fatigue?

Question

I'm struggling to find the right balance in email marketing for my e-commerce store. How often can I send promotional emails with discounts without annoying my subscribers or causing them to unsubscribe? I want to drive sales and keep my audience engaged, but I'm worried about overwhelming them with too many messages. What's the optimal email frequency that maintains customer interest while preventing discount fatigue?

Influencer Discount Code Strategy for Shopify
Influencer discount codes serve two functions: they give followers a reason to buy now (urgency and value), and they give you clear attribution data on which influencer partnerships drive actual revenue vs. just impressions. The structure of the code - expiry, exclusivity, depth - determines whether it converts and whether the partnership ROI is measurable.

Growth Suite: Recovering Influencer Traffic That Doesn't Convert Immediately
A significant portion of influencer-driven traffic arrives, browses, and leaves without converting on the first visit. Growth Suite's Trigger Campaigns catch these walk-away visitors with a behavioral offer before they leave - layering a time-limited on-site discount on top of the influencer code experience. For influencer traffic that arrives via a Growth Suite Growth Link, the influencer code can be pre-applied automatically and a countdown timer initiated, creating a seamless influencer-to-store-to-offer experience that maximizes conversion of the traffic you paid to acquire.
