- You want spam testing, inbox placement, client previews and AI heatmaps in one plan. GlockApps has no rendering previews or heatmaps
- You'd rather start at $9/mo (Basic) or $19/mo (Business) than $59/mo billed annually ($708/yr) for GlockApps Essential
- You want a free tier that renews monthly: 10 spam tests, 10 previews, 10 heatmaps and 3 inbox placement tests, no card required
- You want results in about 30 seconds, an AI assistant on every plan, and a 14-day no-questions refund
// Unspam vs GlockApps
The GlockApps alternative that adds client previews and AI heatmaps
GlockApps is a seed-list placement tester with always-on DMARC, blocklist and IP-reputation monitoring. Unspam covers spam testing and inbox placement too, then adds client previews, AI eye-tracking heatmaps and an AI assistant in one plan: paid from $9/mo, free tier with no card.
Which one fits you?
- You need ongoing DMARC aggregate-report monitoring: GlockApps processes 10,000 DMARC messages a month even on its free plan; Unspam only checks SPF/DKIM/DMARC per test
- You want continuous IP-reputation, blocklist and uptime monitors with email, Telegram and Slack alerts (the Gappie bot) in one dashboard
- You need per-filter spam scores against SpamAssassin, Barracuda and Google's filter, including Gmail tab placement detail

Why teams move from GlockApps to Unspam.
Lower entry price, no expiring credits
GlockApps' Essential plan is listed at $59/mo billed annually ($708/yr); monthly billing runs roughly 30% more, and unused test credits expire at the end of every billing month with no rollover. Unspam's paid plans start at $9/mo, with a 14-day no-questions refund on all of them.
Previews and heatmaps in the same tool
GlockApps tells you where your email landed, but not how it looks. Reviewers note rendering tests require a separate tool like Litmus. Unspam includes client previews and AI eye-tracking heatmaps on every plan, free tier included.
Reports built for fast answers
G2 reviewers say GlockApps' interface and report volume can feel overwhelming for newcomers. Unspam returns a result in about 30 seconds, and the AI assistant on every plan explains what to fix.
