Free tools
Tools to help you build better outbound, from defining your ICP to diagnosing deliverability issues before they cost you pipeline.
ICP Builder
Define your ideal customer profile in minutes. Answer a few questions about your best customers and get a structured ICP you can use to build lists, write copy, and brief your team.
Email Deliverability Checker
Test any sending domain and get a full deliverability report, with an authentication score across MX, SPF, DKIM, and DMARC, plus actionable fixes for anything that's pulling your score down.
SPF Checker
Validate your SPF record instantly. Paste your domain and see whether your SPF is correctly configured, which IPs are authorised, and any syntax errors that could cause emails to fail authentication.
DKIM Checker
Verify your DKIM signature is set up correctly. Enter your domain and selector to confirm your public key is published, your signature is valid, and your record isn't missing anything critical.
DMARC Checker
Check your DMARC policy in seconds. See whether your record exists, what policy is in place (none, quarantine, or reject), and whether your alignment is set up to protect your domain from spoofing.
Blacklist Checker
See if your domain or sending IP is on a DNS blocklist. Check against Spamhaus, Barracuda, SpamCop, and more, and catch reputation listings that quietly send your cold email to spam.
Inbox Volume Calculator
Work out how many inboxes and domains your campaigns need. Enter your monthly prospect volume and emails per prospect to size deliverability-safe sending infrastructure before you scale.
