Find link prospects, send AI-personalized outreach,
and track placed backlinks — in one workflow.
For SEO professionals who need real links, not vanity metrics. ColdSEO handles discovery, personalization, sending, and placement tracking — so you can focus on strategy.
What is ColdSEO? ColdSEO is a link-building outreach platform that finds prospects by domain authority and content topic, generates Claude-powered personalized emails, rotates sends across your inboxes, and tracks which campaigns produce real backlink placements.
Generic cold email tools waste your domain reputation.
Sending 500 lookalike emails a day from one inbox is how SEO pros get blacklisted, marked as spam, and pushed off Google's radar. The "more is better" playbook has been broken for two years.
ColdSEO is built for link-building outcomes.
We optimize for the only metrics that matter: replies, link placements, and domain reputation. Everything in the product — from inbox rotation to AI personalization to warmup — is engineered to keep your sending healthy and your reply rates high.
What does ColdSEO include?
Six tightly integrated systems instead of six tools you have to glue together.
Prospect Finder
Search by keyword, competitor backlinks, content topic, or upload a domain list. Filter by DA, traffic, language, country, and spam score.
AI Personalization
Claude-powered first lines tuned for outreach copy. Reference real things on the recipient's site. Skip the generic templates.
Inbox Rotation
Connect Gmail, Workspace, Microsoft 365, or custom SMTP. Round-robin sends across mailboxes with per-inbox daily caps.
Reply Detection
Threaded replies route into a unified inbox with auto-categorization: interested, not interested, out of office, bounce.
Link Placement Tracking
Set a target URL and we scan replied prospects' sites for the backlink. See exactly which campaigns produce real links.
Domain Health Monitor
Per-inbox reputation gauges, automatic warmup, daily-cap throttling, List-Unsubscribe headers — all the deliverability hygiene built in.

People also ask
What is cold email outreach for SEO?
SEO cold email outreach is the process of contacting website owners, editors, and content creators to earn backlinks, guest posts, or link placements. ColdSEO automates the discovery, personalization, sending, and tracking — without burning your domain reputation.
How is ColdSEO different from Pitchbox, Mailshake, or Lemlist?
ColdSEO is built for link-building outcomes specifically: prospect discovery by domain metrics (DA, traffic), AI personalization tuned for outreach copy, and placed-link tracking that closes the loop. Generic tools optimize for send volume; we optimize for replies and links.
Will ColdSEO get my email account banned?
Not when used correctly. We rotate sends across multiple inboxes, throttle send rates, run continuous warmup, attach List-Unsubscribe headers, and respect domain-level cooldowns. Spam complaints come from generic copy at high volume — both of which we actively prevent.
Do I need my own email account to send campaigns?
Yes. You connect your existing Gmail, Google Workspace, Microsoft 365, or custom SMTP inbox. ColdSEO never sends from a shared infrastructure — every email lands from your domain, which is what makes outreach trustworthy.
How does the AI personalization work?
For each prospect, we feed the recipient's domain, role, and your campaign goal into Claude, which generates a tailored opening line that references something specific about their site. You keep full control of the rest of the email.
Can I import prospects from a spreadsheet?
Yes. CSV import with column mapping is supported on all plans. You can also pull prospects directly from the Prospect Finder using domain authority, organic traffic, language, and country filters.
What is link placement tracking?
When you set a target URL on your campaign, ColdSEO periodically scans replied prospects' sites for backlinks pointing to that URL. You see, in your dashboard, exactly which campaigns are producing real links — not just opens and replies.
Is there a free plan?
Yes. The Free tier includes 50 prospect credits, 100 email sends, 25 AI personalizations, one connected inbox, and one active campaign. Enough to validate the workflow before upgrading.
How long does email warmup take?
Warmup ramps over 2–4 weeks depending on starting reputation. You can begin sending campaigns immediately at conservative limits, and warmup continues automatically in the background to lift your daily cap as your inbox proves itself.
Can my agency manage multiple clients?
Yes. The Agency plan supports up to 25 connected inboxes, 5 team seats, white-label exports, and full API access. Run separate campaigns per client without juggling tools.
