> Cold email outreach for link building with placed-link tracking

Checked Oct 23, 2026 · graded Oct 23, 2026 by ToolGPA.

ColdSEO is a web-based outreach tool for link builders. It finds prospect sites by keyword, competitor backlinks or topic, writes a personalized first line for each email with Claude, rotates sends across your own mailboxes and sorts the replies. It then checks the sites that replied for a link to your target page, so each campaign shows the links it produced. Plans are sized by email sends, prospect credits and inboxes.

## Ways to pay less

- **Save 20% with annual billing** (Annual discount): ColdSEO's pricing page lists annual billing at 20% off: Pro is $63 a month ($758 a year) instead of $79 billed monthly. Source: https://coldseo.com/pricing.php

## Key features

- **Prospect Finder:** Search by keyword, competitor backlinks or content topic, or upload a domain list, then filter by domain authority, traffic, language, country and spam score and pull emails.
- **AI-written first lines:** Claude writes an opening line for each prospect that refers to something on their site; personalization can be switched on or off per sequence step.
- **Inbox rotation and warmup:** Sends go round-robin across your connected Gmail, Google Workspace, Microsoft 365 or SMTP inboxes, with daily caps per inbox, automatic warmup and unsubscribe headers.
- **Reply inbox:** Replies land in one inbox, sorted as interested, not interested, out of office or bounce. AI sorting of replies comes with Agency.
- **Link placement tracking:** Set a target URL and ColdSEO scans the sites of prospects who replied for a backlink to it, so each campaign shows the links it earned.
- **Sequence templates:** Ready-made sequences for guest posts, broken links and resource pages, or your own multi-step sequence.

## Good for

- SEO consultants doing their own link outreach on a small budget
- Link builders who want each campaign judged by the links it produced
- Agencies spreading outreach across many client inboxes

## Worth knowing

- The free plan stops at 100 email sends and 50 prospect credits a month, from 1 inbox and 1 campaign.
- Paid plans have no free trial: they are billed from day one, with a full refund if you downgrade within 14 days.
- Monthly credits do not roll over; one-time packs cost $15 for 500 prospect credits, $10 for 1,000 sends and $8 for 500 AI personalizations.
- More than one seat, API access and white-label exports come only with Agency, and sending needs mailboxes of your own.

## ToolGPA grades

**GPA: 2.0 out of 4**, graded Oct 23, 2026. ColdSEO finds prospects, has Claude write a first line for each email, rotates sends across your inboxes and checks which replies turned into links. It's new (founded 2025), the free plan stops at 100 sends a month, paid plans have no trial, and extra seats, the API and AI reply sorting are held back for Agency.

- **Value for money: C.** Pro is $63 a month billed annually ($79 monthly) for 5,000 sends, 5 inboxes and 2,000 prospect credits, inside this category's usual range. Running short means one-time packs, such as $10 for 1,000 sends.
- **Free plan and trial: C.** Free for good with no card, but 100 sends, 50 prospect credits and 25 AI first lines a month from 1 inbox is a taste you'll use up fast. Paid plans have no trial, just a full refund if you downgrade within 14 days.
- **Features: C.** A prospect finder, AI first lines, inbox rotation with warmup, a reply inbox, sequence templates and a scan for links from sites that replied. Outreach end to end, but AI reply sorting waits for Agency and nothing shows links being re-checked later.
- **Ease of use: C.** No rating on record. You connect your own mailboxes, let warmup run and build sequences before the first campaign goes out.
- **Platforms and integrations: C.** Web only, sending through the Gmail, Google Workspace, Microsoft 365 or SMTP inboxes you connect. The API comes only with Agency at $159 a month billed annually.

## Keep it, or make your own?

**Keep it.** To replace ColdSEO you would be making a network of real inboxes that open and answer your emails. That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 25 of the 50 other link building tools grade higher. It costs $756 a year.

- You could make: Link outreach: an app builder makes this well.
- You could not: A network of real inboxes that open and answer your emails.
- You could not: AI features, unless you pay a model provider for each request yourself.
