What ad formats work best for SaaS and apps?

The most effective SaaS ads show interface screenshots, quick demos or concrete user results. Mimero's software templates include layouts optimized for CTAs like "Free trial" and "Request demo".

Should I showcase features or social proof in software ads?

Combining both works best: use features for cold audiences and social proof (reviews, client logos, metrics) for retargeting. Our templates cover both approaches.

About This Template

This 9:16 Story template is built for promoting an AI email assistant or productivity SaaS using clear, credible social proof. The design features a deep-to-bright blue gradient background with a subtle curved grid pattern, contrasted by oversized yellow quotation marks that instantly signal “customer quote.” A rounded white headline card at the top delivers a bold benefit statement, while the main body copy highlights a concrete outcome (saving 2–3 hours on email). A small circular headshot and name/title line anchor the testimonial in reality and help reduce skepticism at the awareness stage. Psychologically, this creative leans on social proof and time-saving efficiency—two high-intent triggers for busy professionals who feel overwhelmed by inbox work but may not yet be actively searching for a tool. The hierarchy is easy to scan on mobile: headline first, proof second, attribution last. Customize it by swapping the quote for your best quantified result, matching the yellow accent to your brand color, and replacing the headshot with a real customer or industry persona for the strongest trust lift.

When to Use This Template

1Perfect for top-of-funnel awareness ads for an AI email assistant, using a bold headline and a clear testimonial cue (yellow quotes) to stop the scroll.
2Ideal for retargeting busy professionals with a quantified claim (e.g., “save 2–3 hours”), since the layout makes numbers highly scannable on mobile.
3Great for LinkedIn Story-style placements or vertical placements where credibility matters, thanks to the name/title attribution block.
4Useful for promoting a new feature like “smart reply drafts,” because the template’s central paragraph naturally explains a single capability without feeling like documentation.

Marketing Strategy

This template works because it sells an unfamiliar productivity tool to an “unaware” audience using instant social proof. The oversized quotation marks and the headshot/name block make the message feel like a real recommendation rather than a brand claim, reducing skepticism early in the funnel (TOF awareness). The headline is broad enough to hook (“best tool for productivity”), while the body copy adds a specific, believable metric (“2–3 hours”) that anchors value in time saved—one of the strongest ROI frames for email-heavy roles. The clean typographic hierarchy is optimized for fast mobile scanning: promise, proof, attribution. It follows best practices by keeping the benefit concrete, showing who said it, and using high-contrast color accents to guide attention without clutter.

How to Customize

✓Replace the headline with a category-specific promise (e.g., “Inbox zero for sales teams”) while keeping it inside the white rounded card for maximum contrast.
✓Swap the testimonial sentence to include one hard metric (hours saved, replies per day, response time reduced); the centered paragraph layout highlights numbers well.
✓Use a real customer headshot and match the title line to your ICP (e.g., “Customer Success Manager”); the attribution area is the trust driver here.
✓Keep the yellow quote marks, but adjust the shade to your brand accent color—those corners are the visual anchors of the design.
✓If space allows, add a small logo mark near the attribution line only; avoid placing it in the headline box to keep the quote feeling authentic.
