T-Shirt Campaign Launch Checklist for Merch Sellers

Start with a 30‑minute trend scan on Google Trends, Etsy Top Sellers, and Instagram hashtags. Write a concise prompt (e.g., “retro neon skull with bold sans‑serif text, 4‑color palette #ff4500 #1e90ff #ffffff #000000”) and feed it into DesignLumo (https://www.designlumo.com). In seconds you receive a layered PSD file with editable text layers, vector shapes, and color swatches. Duplicate the file, tweak fonts in Canva or Adobe Express, and export PNG and SVG versions. Aim for at least five distinct concepts per hour; track concept‑to‑sale conversion and stop iterating on designs below a 2% CTR benchmark.

Upload your brand assets—logo, color hexes, typography—into DesignLumo’s Brand Kit feature. Enable the auto‑apply toggle so every new AI design inherits your exact colors and font families without manual re‑entry. Cross‑check with Canva’s Brand Kit (canva.com) to ensure any social assets stay on‑brand. Run a weekly audit using a simple spreadsheet that logs asset ID, color code usage, and font match; flag any deviation over 5% variance. Consistent branding lifts perceived trust and can increase average order value by 7‑10% according to Shopify data.

Generate three style variants of a core design (e.g., color swap, typography change, icon orientation) in DesignLumo. Upload each variant to Google Optimize (optimize.google.com) linked to your Shopify product page. Set a 7‑day test with a 10% traffic split and measure add‑to‑cart rate. If a variant outperforms the baseline by 15% or more, promote it to the live product and archive the losers. Document results in a Notion table for future reference, cutting future design guesswork by half.

Export your layered PSD from DesignLumo and upload it to Placeit (placeit.net) using the “Custom Design” option. Choose three realistic models (urban street, studio backdrop, lifestyle flat‑lay) and let Placeit auto‑fit the design onto each apparel mockup. Download high‑resolution PNGs (300 dpi) and a WebP version for faster site loading. Track conversion lift by comparing product page bounce rates before and after adding the new mockups; a 0.5‑second load time improvement can raise conversions by up to 3%.

Once designs are finalized, open DesignLumo and use the “Export All Sizes” command to output PNGs at 300 dpi with transparent backgrounds for each SKU (t‑shirt, hoodie, tote). Name files using a strict convention: product‑type_color_style.png (e.g., tee_black_vintage.png). Upload the batch to Printful (printful.com) via their CSV bulk import tool, mapping each file to the correct product. Verify the mockup preview, then enable “commercial use rights” in DesignLumo to avoid licensing issues. This workflow reduces manual upload time from 10 minutes per item to under 1 minute per batch.

Create a 1080 × 1080 Instagram post template in Canva (canva.com) with placeholders for design image, caption overlay, and CTA button. Export the template as a Canva brand kit and link it to DesignLumo via the “Download PNG” API (requires a free API key). Use Zapier to trigger a workflow: when a new design folder appears in DesignLumo, Zapier pulls the PNG, drops it into the Canva template, and schedules the post in Buffer (buffer.com) for optimal times (based on your audience’s peak hours). Measure engagement lift; a 20% increase in likes is typical after automation.

Design a 600 px wide email header in DesignLumo using your latest merch graphic and brand colors. Export as a high‑quality JPEG (70 % quality) and upload to Klaviyo (klaviyo.com) as a reusable block. Build a segmented flow targeting past purchasers who bought merch in the last 90 days, offering a 15% “new drop” discount code. Set the send time to 10 am local time and track open rates; aim for >25% and click‑through >5%—metrics that typically double repeat purchase frequency.

Create three ad creatives in DesignLumo: a bold graphic, a lifestyle mockup, and a limited‑edition badge. Export each as 1080 × 1080 PNGs under 150 KB. Upload to Facebook Ads Manager (facebook.com/adsmanager) as a carousel ad, linking each card to the corresponding product page. Use CBO (campaign budget optimization) with a $500 test budget, and set a ROAS target of 4:1. Pause under‑performing cards (CTR < 0.8%) after 48 hours and reallocate spend to the top‑performer, improving overall ad efficiency by 30%.

Identify 10 micro‑influencers (10‑50 k followers) in your niche using Upfluence (upfluence.com). Send each a free sample packaged with a QR code linking to a custom landing page built in Carrd (carrd.co) that showcases your latest designs. Encourage them to post a Reel or TikTok using the product within 7 days. Track UGC performance via UTM parameters; aim for at least 200 clicks and a 3% conversion rate per influencer. Repurpose the best videos in your ads and email newsletters for a continuous content loop.
