What is EmailGuard?
EmailGuard is an email deliverability and security platform built for cold outreach teams, agencies, and sales organizations that need to maintain inbox placement at scale. The service consolidates authentication monitoring, blacklist tracking, content testing, and domain infrastructure management into a unified workspace designed to prevent deliverability issues before they damage sender reputation.
Unlike point solutions that address only DNS configuration or spam testing, EmailGuard provides continuous monitoring across authentication protocols (SPF, DKIM, DMARC), real-time blacklist surveillance, and inbox placement validation for major providers. The platform’s domain masking proxies and hosted redirect features are particularly valuable for agencies managing multiple client campaigns or teams running high-volume cold email sequences across secondary domains.
EmailGuard targets operators who treat deliverability as infrastructure rather than an afterthought—revenue teams that understand sender reputation requires proactive monitoring, rapid remediation, and consistent hygiene across every domain and IP in the sending pool.
Key Features
Authentication Management
- Instant DNS Lookup & Generation: Connect any domain to audit existing SPF, DKIM, and DMARC records; generate compliant configurations if records are missing or misconfigured
- Continuous Monitoring: Automated checks verify authentication remains intact; alerts trigger when changes break alignment or policies
- DMARC Analytics: Historical failure data surfaces spoofing attempts, misaligned subdomains, and third-party sender issues
Reputation & Blacklist Surveillance
- Multi-Database Coverage: Monitors 100+ blacklist databases including Spamhaus, SURBL, and domain-specific lists
- Real-Time Alerts: Instant notifications when domains, IPs, or sending servers appear on blocklists, with remediation guidance
- Spamhaus Intelligence Integration: Pro and higher tiers include credits for querying Spamhaus threat data and reputation scores
Inbox Placement & Content Testing
- Provider-Specific Testing: Validates delivery to Gmail, Outlook, Yahoo, and other major inbox providers with placement reports
- 162-Point Spam Analysis: Evaluates email content against trigger networks, header formatting, link reputation, and attachment safety
- Spam Checker: Pre-send content review identifies high-risk phrases, HTML issues, and authentication mismatches
Domain Infrastructure
- Masking Proxies: Route secondary domains through shared or dedicated IPs to isolate primary brand reputation from cold outreach risk
- Hosted Redirects: Managed link shortening with SSL certificates and clean IPs; avoids blacklisted redirect domains in cold campaigns
- Dedicated IP Add-On: Optional $100/month upgrade for isolated sending infrastructure per workspace
Contact Validation
- Real-Time Email Verification: Syntax, domain, and mailbox validation to reduce bounces and protect sender score
- Monthly Credit Pools: 50 to 50,000 verification credits depending on tier; suitable for list hygiene or real-time API validation
Pricing

- Business ($129/month): 75 domains, 300 email accounts, 20,000 verification credits, 500 inbox tests, 1,000 spam checks, 25 proxies, 300 Spamhaus credits
- Agency ($199/month): 200 domains, 1,000 email accounts, 50,000 verification credits, 1,500 inbox tests, 3,000 spam checks, 120 proxies, 500 Spamhaus credits
All paid plans support unlimited workspaces and team members. Custom enterprise agreements are available for organizations requiring higher limits or dedicated support.
Ideal Use Cases
Cold Email Agencies: Domain masking proxies and high domain limits make EmailGuard well-suited for agencies managing outreach across multiple client brands or secondary sending domains. The Agency tier’s 120 proxy slots and 200-domain capacity align with shops running concurrent campaigns for 10+ clients.
Outbound Sales Teams: Revenue teams sending cold sequences benefit from daily blacklist checks, inbox placement testing, and content spam scoring before launching campaigns. Pre-send validation reduces the risk of damaging primary domain reputation during experimentation.
Email Marketers: Marketing teams maintaining multiple subdomains or shared IP pools can consolidate authentication monitoring and deliverability testing in one platform. DMARC analytics help identify unauthorized senders or misaligned third-party services.
Compliance-Focused Organizations: Companies in regulated industries can use EmailGuard’s authentication verification and DMARC reporting to ensure outbound email meets anti-spoofing standards and maintains audit trails for security teams.
Implementation Notes
Onboarding involves connecting domains via DNS verification, then running initial authentication and blacklist audits. The platform guides users through SPF, DKIM, and DMARC setup if records are missing; most teams complete setup within 30 minutes. Weekly or daily monitoring begins immediately after domain connection.
Integration relies primarily on DNS-level configuration rather than direct CRM or ESP connections. Teams use EmailGuard as a monitoring and testing layer before sending through their existing outreach tools (e.g., Instantly, Smartlead, Apollo). The contact verification API can be integrated into custom workflows or list-cleaning scripts, though native integrations with major platforms were not documented.
Deliverability Considerations: Domain masking proxies require careful subdomain setup and DNS propagation—expect 24-48 hours for full resolver updates. Hosted redirects perform best when configured early in campaign planning; migrating mid-campaign can disrupt tracking. Dedicated IP add-ons improve isolation but add $100/month per workspace; shared IPs suffice for most teams unless sending volume exceeds 50k/day per domain.
Limitations: The free tier’s weekly blacklist checks and 10-email-test cap suit experimentation but not production monitoring. Pro and Business tiers offer meaningful credit pools, though high-volume teams may exhaust inbox placement tests quickly during ramp periods. No mention of API rate limits or webhook support for automated remediation workflows.
