What it is

ColdSEO is a link-building outreach platform for SEO professionals, combining prospect discovery, personalized email campaigns and backlink monitoring. Prospect Finder searches by keyword, competitor backlinks, content topic or uploaded domains, with filters for authority, traffic, language, country and spam score. Hunter.io helps locate verified email addresses and check them before a campaign sends. Anthropic’s Claude API generates a tailored opening sentence for each prospect. Campaigns can send through Gmail, Google Workspace, Microsoft 365 or custom SMTP. Replies are threaded and categorized, and campaigns periodically check replied prospects’ sites for links to a chosen target URL. Deliverability controls include inbox rotation, send caps, warmup and unsubscribe mechanisms. ColdSEO offers web and API access, but API access is not included in its plans. The free plan has one inbox, 50 prospect credits and 100 sends per month, 25 AI personalizations and one active campaign. Pro is $79 a month; Agency is $199 a month. Monthly credits expire, and campaigns pause at the cap.
