Most cold email problems aren't the copy — they're the sending domain. SPF not configured. DMARC missing. On a spam blacklist from the previous owner. SendReady audits all of it in 30 seconds and gives you a 0-100 deliverability score. Fix problems before you launch, not after your first campaign bounces. $19 one-time, no API key needed.
Verifies your SPF record exists, is correctly formatted, and doesn't exceed the 10-lookup limit that breaks deliverability silently.
Checks DMARC policy existence, alignment mode (relaxed vs strict), and whether your policy is none/quarantine/reject. Required by Gmail and Yahoo since 2024.
Checks for common DKIM selectors (google, mail, selector1, selector2, default). Confirms your signing key is published and valid.
Confirms your domain has valid MX records configured — the basic check that the domain is set up for email at all.
Checks WHOIS for domain registration date. New domains under 30 days have much higher spam filter suspicion. Flags if you're sending too early.
Checks Spamhaus (SBL, XBL, DBL), Barracuda, SpamCop, SORBS, and 3 others. If you're listed, your emails are filtered before they're read.
SendReady gives every domain a 0-100 deliverability score based on all checks combined, weighted by impact.
New domains need to build sending reputation before cold outreach. SendReady outputs a day-by-day warmup schedule based on your domain age and current score.
