Create an automated welcome series

Set up a three-email automated welcome series for new subscribers from the website popup. Email one should send immediately with a welcome note and the 10% off coupon code NEW10, email two at day 3 with top product picks and social proof, and email three at day 10 with FAQs and a prompt to upgrade. Apply the tag 'WelcomeSeriesStarted' on first send and remove it after the third email. Start the automation for anyone added to the 'Website popups' audience.

Before we activate the welcome series, make approving it easier for the growth lead — surface the expected conversion lift and the coupon margin impact on the first screen, make the coupon code NEW10 prominent in email one, show the timing logic for each step and why day 3 and day 10 were chosen, and flag any content that could increase support requests or conflict with current promotions.

Support just told me customers are redeeming the NEW10 code on returned items and it triggers manual refunds. I launched a welcome series yesterday that uses NEW10 and now I'm worried this will create operational headaches and losses. I don't know how many redemptions to expect or whether the code should be limited by product or first purchase. What's the likely cause and the fastest configuration change to reduce risk before more redemptions happen?

Our automated welcome emails bring more purchases but also spike support and refund work from coupon misuse. This recurring pattern wastes developer and support time. What three habit changes—covering coupon design, email timing, and tagging—would reduce support load while preserving conversion, and which one should we implement first?
