EmailGuard wins for teams managing authentication, monitoring, and verification in one platform. GlockApps wins for teams that need seed-list inbox placement testing depth above everything else. The split is breadth versus depth, and the table below shows where each line falls.
EMAILGUARD VS GLOCKAPPS: FEATURE COMPARISON
WHAT IS THE DIFFERENCE BETWEEN EMAILGUARD AND GLOCKAPPS?
GlockApps is built around seed-list placement testing and multi-filter spam scoring. EmailGuard is a broader [email deliverability](/blogs/email-deliverability) platform covering authentication lookup and generation, DMARC report monitoring, blacklist monitoring, contact verification, and secondary-domain infrastructure alongside placement testing.
The difference shows up in workflow scope. GlockApps answers one question repeatedly and in detail: where did this message land across providers and filters. EmailGuard answers that question, then continues into whether the DNS records are correct, whether the addresses are valid, whether the sending assets are listed, and whether the secondary domains behind a campaign are configured properly. One tool measures placement, the other manages the conditions that produce it.
What Is EmailGuard?
EmailGuard is an email deliverability platform combining inbox placement testing, email authentication tooling, monitoring, and contact verification in a single workspace-based system. The platform runs [inbox placement tests](/blogs/inbox-placement-test) across major mailbox providers, performs SPF, DKIM, and DMARC lookups, generates those same records through wizard and raw interfaces, parses inbound DMARC aggregate reports, monitors blacklist status for domains and IPs, verifies contact lists, and provisions hosted redirects and domain masking for secondary sending domains. Agencies, cold-email operators, and in-house outbound teams use it to manage many domains and mailboxes from one account rather than investigating one asset at a time.
What Is GlockApps?
GlockApps is an inbox placement testing and deliverability monitoring tool built primarily for marketing and outbound teams. The platform sends test messages to a seed network, then reports whether each copy landed in the primary inbox, a promotions tab, or the spam folder across providers including Gmail, Yahoo, AOL, and Outlook. It also scores messages against named spam filters and checks sending IPs against blocklists.
HOW DOES EMAILGUARD TEST INBOX PLACEMENT COMPARED TO GLOCKAPPS?
GlockApps offers deeper seed-list variety, and that is its strongest dimension. Its full inbox placement tests distribute a message across up to 115 seed addresses and multiple named spam filters, producing granular provider-by-provider and filter-by-filter placement data. Practitioner guides frequently recommend it for that reason. Teams whose entire mandate is placement measurement get more raw destination coverage from GlockApps than from any general-purpose platform.
EmailGuard approaches placement testing differently. Tests run against EmailGuard seed addresses across major mailbox providers, and the value concentrates in what surrounds the test rather than in the seed count alone. Placement results attach to connected domains and email accounts inside a workspace, so a result is stored against a specific sending asset rather than existing as a standalone report. Tests run through the interface for one-off checks or through the API for scheduled runs across an entire mailbox fleet. That structure supports mailbox health rotation, pre-campaign gates, and client-facing reporting across many workspaces.
Choose GlockApps when seed and filter variety is the deciding factor. Choose EmailGuard when placement results feed an operational process across multiple domains, mailboxes, and clients.
What Does EmailGuard's Inbox Placement Report Show?
EmailGuard's inbox placement report returns placement outcomes per mailbox provider rather than a single aggregate score. The report exposes four categories of value:
1. Placement location per provider, including primary inbox and spam or junk
2. Categorized tab placement, such as promotions, where the provider exposes it
3. Provider-specific outcomes surfaced for Gmail, Outlook, and Yahoo
4. Comparative results across domains, mailboxes, subject lines, and message variants
Because tests associate with connected assets, results stay comparable over time. A mailbox tested weekly produces a trend line rather than an isolated snapshot, which is what makes automated pausing and restoration of degraded mailboxes possible.
HOW DOES EMAILGUARD SCORE SPAM RISK COMPARED TO GLOCKAPPS?
EmailGuard's Email Tester analyzes a real test send across 162 potential data points spanning subject line, message body, attachments, and authentication. Those data points also cover spam-filter signals, technical message construction, and other deliverability and engagement risks in the scoring model. The output is a score plus prioritized findings, designed as a pre-flight inspection of the complete email rather than of its wording alone.
EmailGuard separates content analysis from full message analysis. The [email spam test](/blogs/email-spam-test) returns a spam score, a count of spam-trigger words, and the highest-risk words found, which suits the copywriting and editing stage. The Email Tester runs after the message is constructed.
GlockApps scores messages against named filters instead. Users select SpamAssassin, Barracuda, or Google's spam filter, then receive numeric scores and a breakdown of the factors contributing to each. That filter-by-filter structure helps when debugging a specific filter rejection. GlockApps identifies which named filter objected; EmailGuard identifies which of 162 signals across content, authentication, and message construction created risk.
HOW DOES EMAILGUARD HANDLE SPF, DKIM, AND DMARC COMPARED TO GLOCKAPPS?
Email authentication splits into four distinct capabilities, and collapsing them into one line hides the real gap between these platforms. The four are lookup, validation, generation, and ongoing monitoring.
EmailGuard covers all four. Lookup and validation run through dedicated tools for each protocol: the [SPF checker](/blogs/spf-checker) inspects published records and flags missing sources, multiple records, and syntax problems; the [DKIM checker](/blogs/dkim-checker-lookup) resolves a domain and selector pair to confirm the public key is published; the [DMARC checker](/blogs/dmarc-checker-lookup) validates policy, alignment configuration, and reporting addresses. Generation runs through separate wizard and raw interfaces per protocol. Monitoring runs through [DMARC monitoring](/blogs/dmarc-monitoring-tools), which receives aggregate reports, parses the XML, aggregates sending sources, and surfaces authentication failures and volume over time.
GlockApps covers lookup and validation, and provides DMARC analytics inside its reporting. It does not generate SPF, DKIM, or DMARC records. A lookup tool reports that a record is broken; a generator produces the corrected record. For teams progressing a [DMARC policy](/blogs/dmarc-policy) from p=none toward quarantine or reject, the difference between reading a report and publishing a fix determines how long the domain sits unprotected.
Can EmailGuard Generate SPF, DKIM, and DMARC Records?
Yes. EmailGuard provides three generator sets alongside its lookup tools. The [SPF record generator](/blogs/spf-record-generator) offers a wizard that builds a record from selected sending services such as Google, Microsoft, and Mailchimp, plus a raw generator supporting failure policy, include, IPv4, IPv6, A, MX, and exists mechanisms. The [DKIM record generator](/blogs/dkim-record-generator) produces a public DNS record and private RSA key from a domain, selector, and key length. The [DMARC record generator](/blogs/dmarc-record-generator) builds a valid record from policy selection and aggregate-report destinations, including multiple recipients. GlockApps offers no equivalent generation capability.
HOW DOES EMAILGUARD MONITOR BLACKLISTS COMPARED TO GLOCKAPPS?
Both platforms check blacklist status, and the difference is continuity rather than presence. GlockApps checks sending IPs against more than 50 blocklists as part of its inbox placement and spam test workflow, producing a snapshot tied to a test event.
EmailGuard runs [blacklist monitoring](/blogs/email-blacklist-monitoring) as an ongoing process across a wider asset set. Coverage extends to domains, IP addresses, sending servers, connected domains, and connected email accounts. The platform supports ad-hoc checks through its [email blacklist checker](/blogs/email-blacklist-checker) for troubleshooting and automated monitoring for detection, sends alerts when a listing appears, notifies when a listing is removed, breaks down the relevant blacklist result, and supplies the information required to pursue delisting. Monitoring cadence varies by plan and product configuration, so verify current behavior against the live plan rather than assuming a fixed interval. A snapshot confirms whether an asset was listed at test time, while continuous monitoring detects the listing on the day it happens and shortens the window during which campaigns keep sending from damaged infrastructure.
HOW DOES EMAILGUARD VERIFY EMAIL LISTS COMPARED TO GLOCKAPPS?
EmailGuard verifies contacts. GlockApps does not offer contact verification, so this is a clean separation rather than a difference of degree.
EmailGuard's [email verification tool](/blogs/email-verification-tool) checks syntax, domain validity, and mailbox existence, then returns one of four status categories: good, unknown, risky, or invalid. Verification runs in real time for single addresses or in bulk through contact-list upload, list management, and downloadable processed results. The API supports signup validation, CRM import cleaning, pre-campaign list cleaning, and lead-enrichment pipelines.
Verification protects reputation at a stage no placement test reaches. Invalid addresses produce hard bounces, and hard bounces damage sender reputation regardless of where valid messages land. A campaign scores well on placement testing and still degrades a domain when 12% of the list does not exist. Status semantics also require business rules: invalid addresses get suppressed, good addresses get sent, and risky and unknown addresses get handled according to source quality and campaign tolerance.
HOW DOES EMAILGUARD PROTECT SENDING DOMAINS COMPARED TO GLOCKAPPS?
EmailGuard provides secondary-domain infrastructure through hosted redirects and a domain masking proxy. GlockApps provides neither, the widest capability gap here.
Cold-email operators run outreach from [secondary domains](/blogs/secondary-domains-cold-email) to keep campaign volume away from the primary domain. Each secondary domain then needs a destination, and a bare registrar redirect is visually and technically obvious to anyone inspecting it. Hosted redirects solve the operational half: EmailGuard assigns clean IP infrastructure from rotating pools, manages SSL certificates, centralizes redirect management, and supports dedicated or custom IPs by request, with API management for provisioning across large domain fleets.
[Domain masking in cold email](/blogs/domain-masking) solves the presentation half. The masking proxy makes a secondary domain display the primary website rather than performing an obvious redirect, so each secondary domain appears to be its own site. EmailGuard reports net-positive reply-rate improvements of 2x to 5x through corporate filtering environments including Proofpoint, Barracuda, and Mimecast. Those figures are EmailGuard's own claims rather than independent benchmarks. Masking carries documented limits: some destination hosts block proxy connections, some require firewall allowlisting, and configurations fall back to hosted redirects when proxying is unsupported.
HOW DOES EMAILGUARD PRICE DELIVERABILITY AGAINST GLOCKAPPS?
Comparable pricing requires a comparable unit, and these platforms meter differently. GlockApps prices around test volume and seed access, with published third-party figures placing entry paid plans between $59 and $85 per month depending on plan structure and billing period. EmailGuard prices around connected assets, with plans defining connected-domain and connected-email-account limits alongside test allowances.
A team running placement tests on three domains pays for tests with GlockApps. A team running authentication checks, DMARC monitoring, blacklist monitoring, verification, and placement testing across 40 domains pays for asset capacity with EmailGuard and receives all five capability sets under one line item. Assembling equivalent coverage from separate tools requires a placement tester, a DMARC platform, a blacklist monitor, and a verification service, each with its own subscription.
Plan quotas and pricing change, so confirm current figures on the [EmailGuard pricing page](https://emailguard.io/pricing) before budgeting. Paid EmailGuard plans have included unlimited team members and unlimited workspaces, which affects per-seat cost for agencies specifically.
Is There a Free Way to Check Deliverability With EmailGuard?
Yes. EmailGuard's lookup and generator tools are free without a paid plan, covering SPF lookup, DKIM lookup, DMARC lookup, and MX record checks, plus the SPF, DKIM, and DMARC generators. Those tools resolve most [email authentication](/blogs/email-authentication) problems on a single domain. GlockApps also offers a limited free tier of two spam tests. Paid plans on both platforms unlock volume, monitoring, and asset management.
HOW DOES EMAILGUARD HANDLE DATA SECURITY COMPARED TO GLOCKAPPS?
Deliverability tooling handles real contact data and real message content, which makes data handling a procurement filter. Test sends contain live copy, contact verification involves uploaded address lists, and DMARC reports expose sending infrastructure.
EmailGuard publishes security documentation and maintains a Trust Center covering safeguards, data handling, and compliance scope. Verify current certifications and their exact scope against those materials rather than assuming platform-wide coverage of any single framework. GlockApps does not surface comparable public security documentation in the materials reviewed, so buyers with vendor-risk requirements should request it directly.
WHICH DELIVERABILITY TOOL SHOULD YOU CHOOSE: EMAILGUARD OR GLOCKAPPS?
Choose based on whether placement measurement is your whole problem or one part of it. GlockApps delivers more seed and filter variety inside a single dimension. EmailGuard delivers authentication generation, DMARC report monitoring, continuous blacklist monitoring, contact verification, and secondary-domain infrastructure alongside placement testing, organized by workspace so multiple clients and domain fleets stay separated.
Teams running one brand and one sending domain need only placement data. Teams running dozens of domains, hundreds of mailboxes, or multiple client accounts need the surrounding operations layer, because the failure modes multiply faster than any single test detects them.
When EmailGuard Is the Better Choice
1. Teams managing authentication across multiple domains and mailboxes
2. Operations requiring contact verification and list hygiene before sending
3. Cold email programs protecting a primary domain through masking or redirects
4. Agencies needing workspace separation, unified monitoring, and client reporting
When GlockApps Is the Better Choice
1. Marketing teams focused exclusively on seed-list placement testing depth
2. Operations requiring maximum provider and named-filter coverage in placement reports
IS EMAILGUARD FREE TO USE?
Yes. EmailGuard offers free access to its SPF, DKIM, DMARC, and MX lookup tools plus all three record generators, with no paid plan required. Paid plans add connected domains, connected email accounts, inbox placement tests, DMARC monitoring, blacklist monitoring, and contact verification volume.
DOES EMAILGUARD OFFER A FREE TRIAL?
Yes. EmailGuard provides trial access to paid platform features, and the free lookup and generator tools stay available without signup. Trial length, card requirements, and included quotas vary by current plan structure, so confirm active terms on the pricing page before starting an evaluation.
IS EMAILGUARD CHEAPER THAN GLOCKAPPS?
Yes, at equivalent capability coverage. GlockApps entry paid plans have been documented between $59 and $85 monthly for placement testing alone. EmailGuard bundles placement testing, authentication tooling, DMARC monitoring, blacklist monitoring, and verification into one subscription, removing three or four separate tool costs.
DOES EMAILGUARD RUN INBOX PLACEMENT TESTS?
Yes. EmailGuard runs inbox placement tests across major mailbox providers including Gmail, Outlook, and Yahoo, reporting primary inbox, spam, and categorized tab placement. Tests run ad-hoc through the interface or on a schedule through the API, with results stored against connected domains and email accounts.
DOES EMAILGUARD CHECK SPF, DKIM, AND DMARC RECORDS?
Yes. EmailGuard covers three separate capabilities per protocol: lookup retrieves the published record, validation confirms syntax and configuration, and generation produces a corrected record. DKIM lookup requires both domain and selector. Each protocol has dedicated wizard and raw generator interfaces for provider-specific and custom configurations.
DOES EMAILGUARD MONITOR DMARC REPORTS?
Yes. EmailGuard receives DMARC aggregate reports automatically, parses the XML, and aggregates results in a dashboard. Reporting surfaces sending sources, email volume, historical pass and fail rates, authentication trends, DMARC failures, and AI-based insights supporting progression from p=none toward enforcement.
DOES EMAILGUARD MONITOR BLACKLIST STATUS?
Yes. EmailGuard monitors blacklist status for domains, IP addresses, sending servers, connected domains, and connected email accounts. The platform supports ad-hoc checks and automated monitoring, alerts when a listing is detected, notifies when a listing is removed, and supplies the result breakdown needed for delisting.
DOES EMAILGUARD VERIFY EMAIL LISTS?
Yes. EmailGuard verifies contacts through syntax, domain validity, and mailbox existence checks, returning good, unknown, risky, or invalid status. Removing invalid addresses before sending reduces hard bounces directly, protecting the sender reputation every subsequent campaign depends on.
CAN EMAILGUARD MONITOR MULTIPLE DOMAINS?
Yes. EmailGuard organizes domains and email accounts inside workspaces, and paid plans have included unlimited workspaces with plan-defined connected-domain and connected-email-account limits. Reporting separates results by workspace and by connected asset, keeping agency client data isolated. Confirm current limits against active pricing.
DOES EMAILGUARD HAVE AN API?
Yes. The EmailGuard API covers authentication, account management, workspaces, team members, domains, email accounts, contact verification, blacklist checks, DMARC reports, email authentication tools, content spam checks, hosted redirects, and spam-filter email tests. Documentation and token creation run through the developer materials.
DOES EMAILGUARD REQUIRE A LONG-TERM CONTRACT?
No. EmailGuard offers monthly billing alongside annual options, so no multi-year commitment is required to access paid capabilities. Annual billing reduces the effective monthly rate. Confirm current cancellation terms and billing intervals on the pricing page, since plan structures change.
