- You want spam testing, inbox placement, client previews and email verification in one plan. GlockApps has no rendering previews or address verification

- You want a free tier that renews monthly: 5 spam tests, 3 inbox placements, 3 device previews, 5 screenshots and 5 heatmaps, no card required
- You want results in about 30 seconds, an AI assistant on every plan, and a 14-day no-questions refund
The GlockApps alternative that adds client previews and email verification

Which one fits you?
- You want DMARC report processing without any paid plan: GlockApps handles 10,000 DMARC messages a month on its free plan. Unspam's Custom plan, from a $5 monthly minimum spent on tests, includes your first DMARC domain free with no cap on report volume, then $6 per domain per month
- 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, Microsoft Exchange Online Protection, Proofpoint and Google's own 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 44% more at $85/mo, and unused subscription credits do not roll over to the next month or year. Unspam's paid pricing starts at $5/mo, with a 14-day no-questions refund on all of them.
No separate render tool needed
GlockApps tells you where your email landed, but not how it looks. Reviewers note rendering tests require a separate tool like Litmus. Unspam includes previews and screenshots across 50+ clients and devices, in light and dark mode, 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.
Unlimited sender accounts
GlockApps caps sending accounts by tier at 1, then 10, then 20. Unspam lets you connect as many sending accounts as you send from at no extra cost, and your monthly quota is metered by tests, not by senders.

Unspam vs GlockApps, answered.
Is Unspam a full replacement for GlockApps?
For spam testing and inbox placement, yes, and it adds client previews and email verification that GlockApps lacks. Both read DMARC aggregate reports now: Unspam's DMARC monitoring is on the Custom plan, with the first domain free. What Unspam does not replace is the rest of GlockApps' continuous monitoring, because it has no IP-reputation or uptime monitors. Neither tool offers inbox warmup.
How does Unspam's pricing compare to GlockApps?
GlockApps' entry Essential plan is listed at $59/mo billed annually ($708/yr); monthly billing costs roughly 44% more at $85/mo, and unused subscription credits do not roll over to the next month or year. Unspam's paid pricing starts at $5/mo, charged per test with a 14-day refund and 15% off annual billing. See pricing.
What's the biggest functional difference between Unspam and GlockApps?
GlockApps pairs placement testing with always-on infrastructure monitoring: DMARC analytics, IP reputation, blocklists and uptime. Unspam pairs placement testing with DMARC monitoring and content tooling: client previews across 50+ clients and devices, an AI assistant and email verification. The gap is narrower than it was, so choose on whether IP reputation and uptime matter to you, or design-side testing does. That same split, monitoring suites on one side and content tooling on the other, is what orders the comparison of this market.
How do the free tiers compare?
GlockApps' free plan includes 2 spam-test credits, 10,000 DMARC messages a month, 5 uptime monitors and 1 IP reputation monitor. Unspam's free plan renews monthly with 5 spam tests, 3 inbox placement tests, 3 device previews, 5 screenshots and 5 heatmaps. AI assistant included, no card required. Run a free test to compare.
