ColdSEO review (2026): is the free plan enough?
Cold email outreach for link building with placed-link tracking
ColdSEO report card
Fair · out of 4.0 · graded Oct 23, 2026
Best for budget cold outreach that counts links won
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.
Who ColdSEO is for
- Fits if you do your own link outreach on a small budget
- Works for judging a campaign by the links it produced
Who ColdSEO is not for
- Tight if you're staying free: 100 sends, 50 prospect credits and 25 AI first lines a month, from 1 inbox and 1 campaign
- Not for you if you want a trial of a paid plan: billing starts on day one, with a refund only if you downgrade within 14 days
- Pricey if you need more than one seat, the API or white-label exports, which come only with Agency at $159 a month
- Watch out: monthly credits don't roll over, and top-up packs cost extra, such as $15 for 500 prospect credits
- Skip it if you don't have mailboxes of your own to send from
Why ColdSEO gets a 2.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyPro 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.
- CFree plan and trialFree 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.
- CFeaturesA 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.
- CEase of useNo rating on record. You connect your own mailboxes, let warmup run and build sequences before the first campaign goes out.
- CPlatforms and integrationsWeb 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 ColdSEO, 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.
What you could make
- Link outreach: an app builder makes this well.
What you could not
- A network of real inboxes that open and answer your emails.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. ColdSEO’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is ColdSEO?
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.
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.
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.
