GlockApps Alternative for Blacklist and DMARC Monitoring
· 5 min read
Checks run by DNS only. Nothing is sent from or to your domain.
The best GlockApps alternative depends on why you are leaving. If you need to know the minute a sending domain or IP lands on a blacklist, and you manage more than a handful of domains, BlacklistMonitoring checks 109 blacklists every 5 to 60 minutes plus SPF, DKIM and DMARC, from $49 a month. If inbox placement seed tests are the only thing you use, GlockApps is still one of the strongest tools for that job.
We make a competing product, so this page sticks to what GlockApps publishes on its own pricing page and says plainly where it is the better buy. Prices change, so check glockapps.com before you sign anything.
Why people look for a GlockApps alternative
GlockApps grew up as a spam testing tool. You send a campaign to a seed list, and it reports whether each copy landed in the inbox, the promotions tab or spam at Gmail, Outlook, Yahoo and others. It has since added DMARC analytics, uptime monitors and IP reputation monitors. The complaints we hear from teams who switch usually fall into four groups:
- Blacklist coverage is tied to IP monitors. The plans count IP reputation monitors (1 on Free, 10 on Essential, 20 on Growth, 25 on Enterprise). Teams on shared sending platforms such as Google Workspace, Microsoft 365 or an ESP care more about their domains than about an IP they do not own.
- Credits run out. Spam tests use credits, and a team testing every campaign across several brands can burn through a plan's allowance well before the year ends.
- Agencies outgrow the counts. An agency with 40 client domains, or a cold email team rotating 60 secondary domains, needs monitoring by the domain, not 10 or 20 IP slots.
- They need the alert, not the test. A placement test tells you how one message did at one moment. It does not wake anyone up when Spamhaus lists your domain at 2 a.m. on a Saturday.
GlockApps pricing in 2026
GlockApps lists four plans on its pricing page. The monthly figures below match the annual totals divided by twelve, so they are the rates when you pay for a year up front.
| Plan | Price per month | Spam test credits | DMARC messages | IP reputation monitors | Uptime monitors |
|---|---|---|---|---|---|
| Free | $0 | 2 | 10,000 | 1 | 5 |
| Essential | $59 | 360 | 600,000 | 10 | 15 |
| Growth | $99 | 1,080 | 1,200,000 | 20 | 25 |
| Enterprise | $129 | 1,800 | 12,000,000 | 25 | 30 |
Every plan allows unlimited DMARC domains, which is a real strength. Extra DMARC volume is billed per 100,000 messages, and spam test credit packs are sold on top.
Is GlockApps worth it?
GlockApps is worth it when your main question is "will this campaign reach the inbox at each provider?" and you test campaigns before you send them. It is a weaker fit when you need continuous blacklist alerts across many domains, because its blacklist checks run through a small number of IP reputation monitors rather than per-domain monitoring.
Put another way, GlockApps answers a question you ask before a send. Blacklist monitoring answers a question you did not know to ask, at the moment the problem starts. Most growing senders end up needing both. The open question is which one you pay the bigger bill for.
GlockApps vs BlacklistMonitoring compared
| GlockApps | BlacklistMonitoring | |
|---|---|---|
| Core job | Inbox placement and spam testing | Blacklist and authentication monitoring with alerts |
| Entry paid plan | Essential, $59/mo billed yearly | Starter, $49/mo, or $24/mo billed yearly |
| Domains and IPs watched for blacklists | 10 to 25 IP reputation monitors | 10, 100, 500 or 5,000 domains and IPs |
| Blacklists checked | Not itemized on the pricing page | 109 IP and domain blacklists |
| Check frequency | Not stated on the pricing page | Every 60, 15 or 5 minutes by plan |
| Inbox placement tests | 360 to 1,800 credits a year | 50 a month on Business, 300 on Agency, 1,500 on Scale |
| DMARC report parsing | Yes, unlimited domains | Yes, 50,000 to 25,000,000 messages a month by plan |
| Uptime monitoring | Yes, 5 to 30 monitors | No |
| Alerts with removal steps | Not described | Each alert names the list, return code, likely cause and removal link |
| Client workspaces and white label reports | Not listed | Agency and Scale plans |
Where GlockApps wins: more placement test volume for the money, unlimited DMARC domains and uptime monitors in the same account. Where we win: per-domain blacklist coverage at volume, checks in minutes, and alerts that tell the person on call what to do next.
Which GlockApps alternative fits your team?
Cold email agencies and outbound teams
Outbound teams run many secondary domains and burn some of them on purpose. What hurts is a domain getting listed and nobody noticing for a week while sequences keep running. Monitoring every sending domain on a 15 minute check, with a Slack alert, is the core need here. Our deliverability monitoring for cold email agencies page shows how workspaces map to clients. Pair it with the placement test only when you change copy or infrastructure.
Email marketing agencies
Agencies need proof for clients as much as alerts for themselves. A monthly report showing that every client domain stayed clean, with the DMARC sources grouped by sender, is what renews a retainer. That is what the white label deliverability reports on the Agency plan are for.
Ecommerce and SaaS teams
Here the money is in transactional mail: order confirmations, password resets, invoices. A listing on the domain that sends those costs revenue within the hour. These teams usually keep a placement tool for marketing campaigns and add continuous blacklist monitoring on the transactional domain and IPs.
Teams that mostly run placement tests
If you send a few big campaigns a month and test every one, stay with GlockApps or compare it with other seed testing tools. You will get more tests per dollar there than from a monitoring product.
Can you use GlockApps and blacklist monitoring together?
Yes, and many teams do. Monitoring only reads public DNS and blacklist data, so it never conflicts with a placement tool. DMARC also accepts several reporting addresses in one rua tag, so both services can receive the same aggregate reports while you compare them. A sensible setup is placement tests before major campaigns and continuous monitoring in between.
One gap neither tool fills for most teams is website uptime. GlockApps bundles a few uptime monitors, and we do not. If you drop GlockApps, put your signup and checkout pages on a dedicated uptime monitoring service that checks every 30 seconds so a down landing page does not get blamed on deliverability.
How to move from GlockApps in an afternoon
- List every domain and IP you send mail from, including secondary cold email domains and the IPs of any dedicated ESP pools.
- Run a quick check on each with the email blacklist check so you start from a known baseline.
- Create your account, paste the list into the bulk add box and choose your alert channel: email or Slack on Starter, plus Microsoft Teams and signed webhooks on Business and higher.
- Add the DMARC address from your workspace to each domain's
ruatag, next to the GlockApps address for the first month. - Keep your GlockApps plan until its credits run out, then decide whether you still need dedicated placement testing or whether the tests included in our Business plan cover you.
How much does a GlockApps alternative cost?
A BlacklistMonitoring plan costs $49 a month for 10 domains and IPs, $149 for 100, $499 for 500 and $1,499 for 5,000, and yearly billing halves each price. Inbox placement tests start on the $149 Business plan with 50 a month. Full details are on the pricing page, and the HetrixTools comparison and MxToolbox comparison cover the other two tools teams most often weigh against us.
The fastest way to decide is to run a check on your own sending domain at the top of this page. If it comes back clean, you know where you stand today. Monitoring is what tells you the day that changes.
