Guides
Cold email infrastructure guides
Every record and check that decides whether an outbound launch is Ready, Needs Fix, or Do Not Launch. What each one is, why it matters, and how to set it up.
Cold email infrastructure scorecard
21 launch checks in one table: what breaks when each fails, which tool category covers it, and whether OutboundQA catches it. Free to download and post.
Open the scorecard
SPF for cold email
The exactly-one-record rule, the 10 DNS lookup limit, and the SPF mistakes that block a launch.
DKIM for cold email
Selectors, public keys in DNS, and DKIM setup for Google Workspace and Microsoft 365.
DMARC for cold email
Policies, alignment, rua reports, and the Gmail and Yahoo requirement that made DMARC mandatory.
MX record checker and mail routing guide
How MX records route replies and bounces, provider records for Google and Microsoft, and common mistakes.
Domain warmup and safe sending volume
Why new domains are high risk, ramp schedules, per-inbox daily limits, and domain age.
Email blacklists: check and delist
The RBLs that matter, how listings happen, how to check before launch, and the delisting process.
Tracking domains: CNAME and SSL
Custom tracking domains, the CNAME to your sending tool, and why broken SSL kills click-through.
Google and Yahoo bulk sender requirements
SPF, DKIM, DMARC, one-click unsubscribe, and the spam-rate thresholds bulk senders must meet.
How the guide set fits together
Each guide explains one part of the launch stack. The launch decision needs the parts together: authentication, routing, tracking links, blacklist checks, and the sender rules Google and Yahoo expect.
Authentication
SPF, DKIM, and DMARC decide whether receivers can trust the sender. Start with the DMARC guide, then verify the record with the free DMARC checker.
Check DMARCLaunch readiness
MX records, sender requirements, domain age, and blacklist checks turn a setup into a launch decision. Use the combined checker when one record is not enough.
Run the readiness checkTool comparisons
Some teams use DMARC platforms for ongoing monitoring. Compare the EasyDMARC alternative page when the job is one workspace verdict before launch.
Compare EasyDMARCRun the matching checks
Use the guides to understand the setup, then verify the records with the same free tools linked from each guide.
DMARC Checker
Look up a domain's DMARC record and read its policy in plain English.
AUTHAuth Checker
Run SPF, DKIM, and DMARC together for a sending domain before launch.
DELIVDeliverability Checker
Check observable cold email infrastructure readiness across MX, SPF, DKIM, DMARC, blacklist, age, tracking-domain, and SMTP egress identity signals.
