3 Recommendations

  • Model future campaigns after Campaign C - replicate its subject line style, content, and CTA.
  • Clean the email list before the next send - Campaign D's 6.7% bounce rate indicates too many invalid addresses.
  • Improve CTAs in underperforming campaigns - use specific action-driven language instead of generic phrases.

04 // Insights & Optimization

From data to decisions

Here's how GoodTea's campaign data translates into strategy.

01 Key insights
High open, high CTR
Campaign C achieved both the highest open rate (40%) and CTR (6.5%) - meaning the subject line, content, and CTA all worked together. This is the benchmark to model future campaigns after.
Open vs CTR gap
Campaign B opened at 28% but only clicked at 3.3%. People opened but didn't act - a classic sign the subject line worked but the email content or CTA failed to follow through.
Conversions follow CTR
Campaign C led in conversions (150) while Campaign D had the fewest (40) - confirming that CTR is the strongest predictor of actual sales, not just open rate alone.
02 Problems identified
High bounce rate
Campaign D's 6.7% bounce rate is well above the industry standard of 2%. This signals a dirty email list with invalid or inactive addresses that need to be removed before the next send.
Weak CTA performance
Campaigns B and D show a significant gap between opens and clicks. The CTAs in these emails are likely too generic - phrases like "click here" or "learn more" don't give recipients a clear reason to act.
03 Recommendations
→
Model Campaign C
Replicate Campaign C's subject line style, email structure, and CTA language across future sends to consistently hit higher open rates and conversions.
→
Clean the list
Remove invalid and inactive addresses before the next send. A clean list improves deliverability, reduces bounce rate, and ensures metrics reflect real engagement.
→
Sharpen the CTA
Replace vague CTAs with specific, action-driven language. Instead of "Learn more" try "Shop the spring collection" or "Claim your 25% off" - clear and direct drives more clicks.
04 Optimization examples
Subject line
Before
"Spring sale - shop now"
↓
After
"These ones have your name on them, Suzi - GoodTea spring teas are in"
Personalized, curiosity-driven, no spam triggers
Call to action
Before
"Click here" or "Learn more"
↓
After
"Shop the spring collection"
Specific, action-driven, tells the user exactly what happens next
Email structure
Before
Long text blocks, no images, buried CTA at the bottom
↓
After
Short intro, bullet points, product images, one clear CTA
Easy to scan, visually engaging, CTA visible without scrolling
Bonus Advanced strategy
A/B
A/B Testing
Test two subject lines per campaign - one direct, one curiosity-driven. Send each to 20% of the list, then send the winner to the remaining 60%. This is how Campaign C's style can be validated and refined over time.
Best send time
Industry data shows Tuesday and Thursday mornings between 9–11am consistently produce the highest open rates. GoodTea should test these windows against current send times to find what works best for its specific audience.
↓
Funnel improvement
The open-to-click gap across campaigns suggests a mid-funnel leak. Adding social proof (reviews, ratings) directly inside the email body - before the CTA - can bridge this gap and push hesitant readers to click.
