Gleam vs ShortStack: Which Giveaway Platform Is Right for You?

ShortStack and Gleam both run giveaways, but they approach them from different directions.

ShortStack is as much a landing page builder as a contest tool. The campaign page is the primary canvas, and that orientation makes it genuinely strong for agencies and brands where visual presentation is the priority. If the brief is a beautifully designed, branded promotional experience, ShortStack delivers.

Gleam is built for what comes after that - campaigns that grow email lists, social audiences, Discord communities, and e-commerce customer bases simultaneously, verified at the action level, feeding into a connected marketing system that keeps working after the giveaway closes. For brands where the campaign is part of something bigger, Gleam is built for it.

ShortStack's landing page builder is its clearest strength. Where most contest platforms treat the campaign page as an afterthought, ShortStack makes it the centrepiece. Fully branded, mobile-responsive campaign pages with custom templates, photo contests, quizzes, spin-to-win mechanics, and voting campaigns - all without a developer. For agencies running client campaigns where the visual experience matters as much as the outcome, that depth is genuinely useful.

The built-in email functionality adds to that picture. Autoresponders, scheduled sends, and follow-up campaigns are all native, which means post-entry communication doesn't require a separate email platform.

Customer support is consistently well-regarded, with reviewers across G2 and Capterra noting fast response times.

ShortStack caps stored entries on every self-serve plan. The Startup plan at $49/month stores 2,000 entries. Business and Growth plans store between 10,000 and 25,000. Unlimited entries require enterprise pricing negotiated directly with ShortStack. Reviewers on Capterra note this as a consistent frustration - having to manage entry limits across campaigns adds operational overhead that shouldn't exist on a paid plan.

Gleam does not cap entries on any paid plan. A campaign that goes viral does not hit a ceiling. A brand running multiple concurrent promotions does not need to track limits across each one.

For brands running campaigns at any meaningful scale, this is the most practical difference between the two platforms.

Gleam verifies entry actions through platform integrations where APIs allow it - checking that a social follow, video view, or page visit was actually completed before recording the entry. On Pro and above, campaign operators can access all entry data and investigate individual entries before drawing winners. A site-wide user block removes bad actors across all Competitions and Rewards in one action.

ShortStack's approach is form-based. Entries are collected through landing page submissions, and fraud protection focuses on moderation tools for those submissions. This works well for photo contests and form-based lead capture, but does not extend to verifying that a social follow or video view actually happened.

For brands where lead quality affects email deliverability, retargeting accuracy, or CRM data integrity, Gleam's API-based verification is a more robust foundation.

ShortStack runs contests and landing pages well. The gap with Gleam opens up when a campaign needs to connect to a wider marketing system.

Gleam is built around four products that work independently and together: Competitions, Rewards, Capture, and Galleries.

A Gleam Rewards programme runs year-round, giving every participant a guaranteed outcome - a coupon code, gated content, early access - rather than a one-in-thousands chance. ShortStack has refer-a-friend mechanics within campaigns but nothing equivalent to a standalone rewards system.

Gleam Capture converts site visitors who never entered a contest - exit intent popups, scroll-triggered forms, countdown banners - feeding the same integrations as every other Gleam product. ShortStack has no equivalent.

Gleam Galleries pulls user-generated content from hashtags and campaign submissions into a live, embeddable social proof wall on your website that keeps working after every campaign closes. ShortStack collects photo contest submissions but has no standalone hashtag-fed gallery.

And because all four products share the same platform, a user who enters a competition, unlocks a reward, and later subscribes via a Capture popup is one enriched contact in your CRM - not three separate records from separate tools.

Gleam connects to 40+ email and CRM platforms, including Klaviyo, Mailchimp, HubSpot, Salesforce, Marketo, ActiveCampaign, and Drip. E-commerce integrations with Shopify and WooCommerce let brands verify purchases as entry actions or connect campaign data directly to their store.

ShortStack integrates with major email platforms and supports Zapier for broader connections. The CRM integration depth is more limited, and for brands where campaign data needs to flow into a sales pipeline or marketing automation platform, that gap matters.

ShortStack starts at $49/month with a 2,000 entry cap. Gleam starts at $29/month with no entry caps and no campaign limits. The free plan comparison reflects the same gap: Gleam's free tier runs unlimited campaigns with limited features, while ShortStack's caps at 20 entries - not enough to run or meaningfully evaluate a real campaign.

ShortStack is a well-built platform for agencies and brands where the campaign experience needs to look exceptional. Within that use case it performs well, and the landing page builder is a genuine strength.

For brands building repeatable audience growth rather than one-off branded experiences, Gleam is the stronger choice. No entry caps, API-based action verification, a broader integration ecosystem, and a full platform that extends into rewards, lead capture, and UGC - all at a lower starting price, all on one platform feeding the same data.
