Should I offer a discount in exchange for an email address?

Question

I'm running an e-commerce store and want to grow my email list while also potentially increasing conversions. I've heard about email capture strategies involving discounts, but I'm unsure about the best approach. Is offering a discount in exchange for an email address an effective marketing tactic? What are the potential benefits and risks? I want to ensure I'm not devaluing my brand or attracting low-quality leads while trying to expand my customer database and improve my marketing reach.

Discount-for-email is the most common and highest-converting email capture strategy in e-commerce. The question isn't whether to offer it, but how to do it without training customers to only buy when discounting or attracting low-quality subscribers who never convert.

Making Discount-for-Email Work Without Training Deal Seekers

Make it explicitly first-order only: "10% off your first order" not "10% off any order"
Set a genuine expiry: Code expires in 48-72 hours - creates urgency to use it
Deliver value beyond the discount: Your email welcome series should be worth reading even after the discount is used
Segment discount subscribers separately: Track their LTV separately to see if they become good repeat customers
Don't re-discount excessively: If someone joined for a discount, don't keep offering them discounts - treat them as a regular subscriber after the welcome offer

Key metric to track: What % of email sign-ups from your discount popup convert to a purchase within 30 days? This tells you the quality of your capture rate. If sign-up rate is high but conversion is below 20-25%, your popup is collecting uninterested subscribers and the discount offer needs adjustment.
