What's the optimal frequency for sending promotional emails?

Growing Your Email List for Cosmetics

List growth rate and list quality are both important - but quality wins long-term. A list that grows by 500 genuinely interested subscribers per month will consistently outperform one that grows by 2,000 random signups, because deliverability, open rates, and revenue per email all depend on subscriber engagement.

List Growth Tactics by Quality and Volume

Cosmetics-Specific List Building Tactics

• Skin concern quiz: "What's your #1 skin concern?" - collects email AND segmentation data simultaneously. High opt-in rate because customers receive personalized product recommendations.
• Shade match tool: Email required to receive shade recommendation results
• Sample request: Email address to receive product samples or deluxe minis
• Waitlist for new launches: Email capture through product pre-launch interest creates high-intent subscriber segments

Smart Capture with Growth Suite

Growth Suite's Personalized Email Capture Campaigns use behavioral targeting to show capture prompts only to visitors who demonstrate genuine interest - those who have browsed multiple products, spent meaningful time on key pages, or shown exit behavior after significant engagement. This targeting ensures you're capturing subscribers who are likely to open and buy, rather than maximizing raw signup volume. The result is a faster-growing engaged list rather than a large unresponsive one.
