In their own words
ColdSEO
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.
LinkAssistant
LinkAssistant supports link-building campaigns from prospect discovery and contact research through outreach and backlink monitoring. It lists 10+ ways to find opportunities, including searches tailored by location, niche, and SERP type. Users can also identify prospects from competitors’ backlink profiles using broken-link building and backlink-gap techniques. Prospect assessments can include InLink Rank, domain age, organic traffic, Page Authority, and indexed-page count. Outreach tools cover contact discovery, customizable email templates, and tracking sent emails, replies, and follow-ups. A verification tracker checks whether acquired links remain in place and can flag removals or nofollow tags. Reports can be customized, white-labeled, and scheduled for delivery. The software runs on Linux, macOS, and Windows. The free license allows up to 1,000 prospects per project. Professional costs $129 a year and Enterprise costs $259 a year; both list unlimited prospects per project. Enterprise also lists report saving, emailing, scheduling, and CSV, SQL, and HTML export. The company says its tools serve SEO professionals, marketing companies, website owners, and web developers.
